Turbocharger, Turbochargers, Turbo charger, Turbo Kits, Auto, Car

Solution has been made, but for now, results are quite remarkable. For example, the following introduction to the MINICooperS we are going to carry a 1.6L turbocharged engine maximum power of 175 horsepower, while the new wing of the listing of Core Mazda 2.5L naturally aspirated engine maximum power is only 169 horsepower, this shows turbocharged engine volumetric efficiency is much higher than naturally aspirated engines. So that a substantial power increase is how to achieve it?

● Basic principles of turbochargers – we first explain this simple principle well known to the reader can skip this part

On the principle of turbochargers we have said many times before, this is no longer particularly detailed analysis. In short turbocharger intake side and exhaust from the side of two parts, engine emissions can drive a turbine blade inside the exhaust side, as this leaves the intake side through the bearing and connected to the blade, so the exhaust side leaves can be driven into the gas side leaves, and leaves quickly turn into the gas side effect is that you can produce more fresh air into the inlet, thereby to improve the efficiency of the engine.

In recent years, upgrading of company cars as Automotive, a number of heavy cargo vehicles generally use diesel turbocharger, but often occurs when using early damage of turbocharger failure, analyze the causes, mainly focused on the use of turbochargers, caused by improper maintenance. Is on factors affecting the life of the turbocharger, failure and diagnostics to analyze and explain the use of precautions, intended to reduce the turbocharger failure, prolong life, reduce maintenance costs.
An exhaust gas turbocharger basic knowledge and working principle
Turbocharger is used to increase engine power and reduce emissions of key components. Turbocharger itself is not a power source, which uses the residual energy of engine exhaust to work, its role is to provide more air to the engine. It uses the engine exhausts energy, drive high-speed rotating turbine, and turbine driven compressor impeller coaxial high-speed rotation, press the air to the engine cylinder, the engine of inflation increase the amount of fuel available for more complete combustion, thereby increasing engine power, reducing fuel consumption, and because the improvement of combustion conditions to reduce the exhaust emissions of harmful substances, can reduce the noise.
Turbocharged diesel engine after change after the performance, it makes the engine power has greatly increased, supercharged engine’s power can be increased after the 20% ~ 40% to WD615 machine, for example, the engine’s mechanical efficiency, Turbocharged Engine auxiliary systems consume very little power to increase, although since the outbreak of pressure, the friction surface, friction losses increase, but the large increase in engine power, mechanical efficiency increased nearly 8%. Fuel consumption is decreased, pressure increased backward air pressure, improved combustion conditions, mechanical efficiency, reduce fuel consumption, power quality and significantly reduced engine unit, but also brought an engine with new problems, such as: the engine’s mechanical load increase the heat load increases the engine and so on.
2 factors affect the life of the turbocharger
Use, we found that damage to the turbocharger and engine wear is always in and around the failure occurs after the number of diesel engines will lead to an abnormal condition turbocharger damage. Turbocharger failure, 40% were due to poor lubrication result, 40% were due to external debris caused by the turbocharger, 20% of other causes.
2.1 lubricants. Turbocharger lubricating oil used for lubricating and cooling, but the turbocharger work, its rotor speed up to tens of thousands to hundreds of thousands per minute switch, oil was labeled as a foam, cooling and lubricating properties of their decline, so lubrication system must guarantee the provision of adequate lubrication. If the temperature around 600 ℃ when the exhaust through the turbine room, inadequate bearing lubrication and cooling, lubricating oil channels in the walls of his ring coking, gradually blocked oil duct.
If the dirty oil will soon damage the internal parts turbocharger. As containing dust, pulpy sediment and metal particles of oil will rapidly destroy the parts with the clearance, bearing surface scratches and wear. All these will lead to increased resistance to axial rotation of turbine and loss of balance, the axis of rotation speed decreased, resulting in increased engine power loss, and the rotating imbalance will soon lead to damage to the turbocharger components.
If the quality and grade of oil aging, the various oil additives can not meet the heavy load of work turbocharged diesel engine lubrication requirements, will accelerate the oxidation of lubricating oil deterioration, will increase diesel engine and turbocharger wear parts.
Start the engine, turn off the correct method of operation will seriously affect not turbocharger life. If the engine starts, immediately rose to very high speed, lubricant can not arrive in time to accelerate the turbocharger bearings and wear. After the diesel engine flameout, if not first make the supercharger cooling, and suddenly turn off, stop the supply of oil to the supercharger, turbocharger internal parts will result in overheating, bearing oil duct obstruction in the oil carbonization oil Road, will have bearing bitten the risk of death.
Turbine seal ring leakage caused by the back of coke, will rotate rotating parts made Shibuya, lost power. Rotating parts of the imbalance is caused by leakage of the sealing ring is an important reason. Crank vent or return pipe plug turbocharger or resistance is too large, it can cause seal ring leakage.
2.2 intake. The quality of the work turbocharger is also dependent on the intake system, only the supply of adequate, clean air to ensure the long-term trouble-free turbocharger work, so life expectancy. Therefore, we should regularly check all connectors and hoses into the trachea sealing to prevent leakage. If the compressor to the engine intake pipe leakage, reduced inflation, will result in diesel black smoke. When there are larger particles of dust or sand into the turbocharger compressor damage immediately. Smaller particles also make the work of bending or cutting wheel cutting blade, and make it out of balance, causing bearing and seal wear ring increased. Unbalanced rotating parts and bearings collide, so that bearing on the oil duct narrowing, leading to poor lubrication. As the bearings wear, with the gap increased, so that the work of the compressor or turbine wheel blade against the shell, this fault signal is larger than usual, a lot of noise.

Proposed in the concessions of the brand since November 4, the ticket slightly above 61 000, the last Audi A7 Sportback offers a pause in our columns for a new promotional video. Ambiance SF program that last spot.

Not much more to tell if you invite them to discover immediately below this new commercial for the Audi A7 Sportback!

On the occasion of the last event “Nardo Highspeedtest 2010″ (so you know where), the German tuner MTM has deployed fine linen. Finally, beautiful bombs with the presence of a triplet of Audithat the vitamin content RS6 Clubsport , the prototype or the R8 coupe TT RS. Among the monsters to attack it is ultimately the super sedan that has the best shot out of the game (in terms of the speedometer).

During the presentation of the Audi RS6 Clubsport by MTM, we argued that the German trainer expected a few v-max 350 km / h at the time to go hunting record. Better.

Yes, the sedan has simply shameless reached the top speed of 362.5 km / h pulling back on the potential of its 5.0 V10 bi-turbo pushed to 730 c..Enough to afford a nice match with some of the most spicy creations Catalogue G-Power …

Note also that the prototype R8 V10 MTM pushed to 777 hp and 880 Nm (the famous proto left to the state site ) failed in his quest to rise above 350 km / h to settle for 347.6 km / h when the mixture over the TT RS coupe, 472 hp, signed a top speed of 312 km / h.

The mechanism that does this is not ‘nothing but a waste-gate valve call that is placed in the vicinity’ of the turbine can, when opened to drain the gas, thus preventing the invest.
The wastegate and ‘as I said a valve and its drive using an expansion box connected to a pneumatic tube to the discharge of the compressor where you have the turbo boost pressure, and’ visible in the photo above with the name “sensor wastegate “.
The azionamentodella wastegate is via a rod that connects to the expansion box on that.
This rod has a stroke that allows for the opening of the wastegate-type progressive and directly proportional to boost pressure.
The movement of the rod but ‘, is bound by a spring and’ contained in the SO expansion box ‘because it moves and’ must boost pressure is such as to overcome the spring load.
From this we understand that and ‘the kind of spring (or rather its preload) to define the maximum boost pressure.
In general, Tc installed in engines for cars are equipped with integrated wastegate, but there are other applications where it is ‘a separate component (typically used in motor racing) and others, and’ absent.
There is also another class of turbo wastegate but the lack of a system with variable geometry for the orientation of the exhaust gas, in this case, ‘the very variable geometry to determine the extent’ of overeating, and these are characterized Tc from a field of operation more ‘large and a small turbo-lag.
An engine equipped with Tc and ‘able to swallow more’ than its volumetric air would allow in terms of aspiration, so that ‘its volumetric efficiency, and sometimes also abundantly than 100%, that’s why’ and ‘easy to run into engine which, although small airspace without express great powers reach high engine speeds.
The use of Tc pero ‘implies a particular distribution of engine torque, in fact, if the volume of exhaust gases’ (eg low speed) too low, the motor acts like a vacuum cleaner (and worse).
The turbo engine has three operating conditions: naturally aspirated, supercharged and transition.
That transition and ‘characterized by the abrupt transition between the other two were repercussions on the power of the motor that will see’ in a narrow range of rpm also increased by 100%.
Also during this transition state and ‘very clear that phenomenon known as turbo-lag that is not’ nothing but the response time of the engine or turbine to the accelerator.

Ask to be gradually and ramp up as the basis of all fetish preparers Instead, the new generation of the Porsche 911 is revealed here and there in the magazine aisles Helvetic. On the stand SpeedART, it is possible to discover and appreciate the SP91-R .

Based on the latest 911 Carrera S (supply will also be offered for the Carrera), the program declined by Germans SpeedART revolves around the known principles from mechanical alterations and new aesthetic.

The coupe from Zuffenhausen is offering a reprogramming of the ECU and win a new exhaust system in order to claim an additional mechanical suspicion approval. In figures? Power increases by 20 hp to 25 Nm of torque available in addition. It starts modestly in SpeedArt.

A little less modest turn out the other changes between new side skirts, diffuser and rear spoiler and new front bumper. Finally this version adopts rims 21 “when the passenger has to offer something new between leather and Alcantara. Rather finally sober.

The Ibiza Seat in a real icon. This is the best selling model of the brand. The revolution would therefore risky and this is done, for this new version, more of a face lift than a total change. It’s been four years that the Seat is the fourth generation on our roads and version 2012 does not move away too as we have seen the last Geneva Motor Show with the five-door, SC for three doors and break aka ST. For version Cupra it will unfortunately have to wait the end of 2012 we are told, to know its characteristics. In the meantime we have tried to the most powerful of the range, Version 1.4 TSI FR 150 horses.

Bad weather was the rendezvous during our test on Spanish soil, it does not stop to enjoy his new hood over his sculpted trapezoidal grille and larger.The change does not stop there as the design of the front bumper also adopts a trapezoidal offering a more stable. The optical adopt the new signature LED Seat (our test model was equipped with the optional bi-xenon), which stresses a desired character more powerful. Seat signature is also found in the back with the V-shaped lights for the night, and even remotely easy to spot. The rear bumpers are also slightly redesigned, giving a look a little more robust self.

The restyling is not trivial: the average age of buyers of Ibiza is the youngest in the class with 37 years and the design is cited as a purchasing criteria most important by stakeholders. The target is clear: young people, with an emphasis on technology. This new identity heralds the future brand models and Seat wanted to accompany him with a new slogan that wants to marry the famous Emocion important Spanish Seat and the other component of brand identity, the German technology.

German technology, is found primarily in the Seat Ibiza via TDI and TSI engines, the DSG box, the Start-Stop system etc.. coming from the VW group. The petrol versions range from cheap 1.2 liter 60 hp 1.4 TSI version of our 150. With its 220nm of torque from 0 to 100 is shot down in 7.6 seconds and top speed reaches 212 km / h. This engine is now available for version ST wagon, bringing for the first time the name FR. The more sober of the petrol range is the 1.2 TSI Ecomotive consuming an average of 4.9 litres/100km. Side the TDI range consists of 1.2-liter TDI CR 75 horses, its version Ecomotive, the 90 horsepower 1.6 liter, 105 horsepower and 143 horsepower 2.0-liter finally.

Our version was quite nervous and enjoyable with the seven-speed DSG but also light weight, a good place for Spain: Ibiza FR seems rather small to compete (1280 kg against 1453 kg for example for an Opel Astra 1.4 liter 140 horsepower). Activation of Mode S for Sport makes the machine much more responsive and thoroughly pedal, stationary and on damp ground, you better have both hands on the wheel to avoid the train before drift . In this mode, the engine noise is not unpleasant and is less conspicuous than when the function is disabled. The starter is made ​​with a stopped engine noise fairly shouting until 6000 rpm. ESP is standard on our version and is associated with differential lock XDS for engines above 100 horsepower.

Inside the new three-spoke steering wheel dominates the new dashboard whose presentation has been improved, although we still find quite austere.The sports seats are reinforced laterally and the steering wheel and the gear knob are leather-wrapped standard on FR. For other versions, this option is that it will acquire them. The finish is good but the materials on this high-end version sometimes weak as the inside lining of the roof, a sort of basic fabric ready to pilling arrived first month. It must be remembered, however, seen that one is in a car with 20,000 euros, making it more accommodating.

Our version of EN 140 is indeed the most expensive version of the gasoline line before hosting the Cupra as it is billed 20,155 euros, the diesel version 2.0 TDI FR 143 horses being billed 21,080 euros. At the first price for this 5-door Seat offers us the 1.2 petrol 60 hp starting at 11,950 euros against the 1.2 TDI diesel with 75 horsepower is 14,975 euros. Ecomotive versions will be for their proposed 15,675 euros in style and finish gasoline and 17,360 euros in the same finish.

A good design reworked, a stable, strong in the version tested, that about sums up this new Seat Ibiza, despite finishing still below what we can offer Volkswagen. The mission is to provide a vehicle and affordable technology seems accomplished. Marketing begins this month.

Thus, everyone enjoys the peace of mind with regard to order a turbo with us.

The turbo (turbo):The turbo is a turbine driven by exhaust gas that returns the gas compressed in the inlet. It allows to boost engine power.

When to change the turbo?Several cases may be involved in a turbo problem. A lack of engine power, excessive smoke, high fuel consumption, overheating, exhaust temperature is too high, leakage of oil from the turbocharger can be symptoms attributable to the turbocharger. We must then verify the origin of symptoms.

The turbo engine

The turbocharger is a mechanical part annex to the engine for increasing gas pressure allowed, allowing better filling of cylinders in air. The turbo is compatible with internal combustion engines or compression ignition (diesel). Is the compression of gas exhaust , which can rotate the turbine.

The turbocharger comprises a turbine and a compressor. The turbine is driven by the gas exhaust , it drives the compressor that compresses air under pressure to the engine intake. For most turbochargers, they are composed of:
- An air filter
- A cartridge air filter
- An inlet air to the turbocharger with its O
- An upper level of oil
- A cover oil filter
- An oil pan
- A turbocharger
- A sleeve lubrication of the turbocharger, two hollow bolts and gaskets.
- An oil return line with its attached
- 2 seals of the turbo compressor

There are several types of turbo different quality. The advantages are numerous. For a 150 hp 2-liter engine, a turbocharger can develop over 200 hp. The car then has acceleration and overall power of lightning. The counterpart is that the engine is pushed to its limits and you have to do a thorough review of the engine.

Maximize the life of a turbo

It is possible to optimize the life of the turbo. You should know that turbo starts to operate only from a certain engine speed. Having a turbo on his car requires meticulous maintenance. To optimize your vehicle. There must be a warming up before using the vehicle. Before switching off, you must let it run a while the engine idling. For it is oil pump that allows the lubrication of the axis of rotation of the turbine. Excluding the oil pump is driven by the engine, thus preventing an engine off the oil to lubricate properly turbine of the turbocharger compressor. We must therefore wait a few minutes to idle before turning off the engine.

When replacing a turbocharger?

It is not necessarily always have to replace a turbo. Sometimes just a simple repair. Some symptoms may be due from the compressor, but the failure may come from elsewhere. The key symptoms you may experience with the possible causes.

Choosing a turbocharger

There is only one consistent reference for your turbo vehicle. When searching you must learn the turbo code. This code is stamped on your turbocharged vehicle. 6 digits, it usually starts with a 7 or 4.

Instructions for installation of the turbocharger

The replacement turbocharger discussed below corresponds to the references Mitsubishi 491730750 … 753420 … and Garret, these turbos are compatible with some vehicles Citroen C2, C3, C3 II, C4, C4 PICASSO, XSARA PICASSO, C5II, C5 (X7) and BERLINGO II.
The benefit is relatively similar for other types of turbochargers.

Start by making a check of the cleanliness of the intake system.
- Check the air filter, replace if necessary.
- Clean the air filter housing.
- Check for foreign matter in air ducts downstream and upstream of the turbocharger.
- Check that the sleeves of the turbocharger are blocked or pinched.
- Make sure there is no foreign body leaving the head cover of the circuit breathing oil fumes.
- Remove if not already pre-filter which is running at the turbo side hose lube engine block. This filter should be removed when the first oil change .
- Empty résonneur any remaining oil. Replace the gasket at the inlet of the turbocharger, the turbocharger inlet fitting and O-ring air inlet of the turbocharger.
- Remove the heat exchanger air / air: Check for oil and foreign, reverse the heat exchanger air / air, wait 10 minutes. If you find oil or foreign bodies inside, clean with solvent.
When you remove the turbo, check for the nut assembly of the compressor wheel of admission.It can be dismantled due to a sudden stop of the whole circle. This is due to a lack of lubrication or the passage of a foreign body in the inlet of the turbocharger. If the bolt is missing, find it before it causes other damage.
- Replace the stem oil with a new one.

In the case where the vehicle exceeds 60 000 km it is important to make additional checks:
- When you remove the oil pan, check the appearance of oil and walls of the sump.
If the oil is thick: Disassemble valves and check for oil degraded. If this happens you must thoroughly clean the engine or change.
If the oil looks normal: Check the filter clogging suction. If one bolt is loose or if the filter has deposits, replace the intake filter.
If everything is fine, no problem, put properly in place the oil pan.
- Remove the vacuum pump and clean the strainer inlet oil vacuum pump.
- Replace the cartridge with oil.
- Replace the drain plug with new gasket.
- Fill the engine oil quantity recommended for the engine.
- Replace the filler cap.
- Replace the oil dipstick.
- Prime the oil system before starting the engine by disconnecting the injectors, start and run engine for 15 seconds. Reconnect the injectors and erase fault codes.
- Start the engine and let it idle for 5 minutes to allow the turbocharger to reach the correct pressure.
- Stop the engine and wait 15 minutes.
- Recheck the oil level, it should be between the levels prescribed by the manufacturer of the turbocharger.
- Replenish oil if necessary.
- Check the operation by a road test.
- By disconnecting the fuel inlet air to the turbocharger, check the blades of the compressor wheel inlet.

Expert Tips for turbo Yakarouler

Please note, manufacturer warranties do not include the turbo failed because of lack of maintenance associated with these requirements
- Check in an assembly that neither the oil inlet or outlet are not blocked particles deposited on the inner walls of the pipe. Beware also that these pipes are not twisted or bent.
- Always use an oil compatible with your engine.
- Follow the oil change intervals. The engine oil on normal usage should be replaced every two years maximum, even if the mileage is low.
- Follow above all mileage limits before discharge.

After the A6 sedan shown in Detroit last January, Audi unveils its wagon variant before.
As for the trunk version, this fourth-generation wagon road of the Rings adopts a rather conservative style. Indeed, his general appearance, albeit elegant, seems anything but revolutionary over the model it replaces.

To remember the Audi A6 in 1997, the style is both chic and avant-garde from the time we said that the Ingolstadt manufacturer really comes in range. An impression reinforced by the strategy followed during the transition between the current Audi A8 and its predecessor.

If the bow of the new Audi A6 Avant long by 4.93 m optical adopts grille and reshaped, and especially the stern profile appears almost unchanged.

A wide, 87 m high of 1, 46 m, the new estate of the Ingolstadt firm announces a wheelbase of 2.91 m. Benefiting from aluminum components, he sees his weight down to 20%.
Practicality, cargo volume is announced to 565 liters or 5 more than the BMW 5 Series Touring but 130 less than the Mercedes E-Class Estate. Note that the trunk has a double floor as well as slides and straps.

In terms of engines, the Audi A6 Avant 2011 is proposed to launch six engines with direct injection: two petrol and four diesel including the new 3.0 TDI 313 bhp twin-turbo. On transmission, customers can choose between a manual six-speed box Robotic S tronic seven-speed, the multitronic continuously variable automatic transmission or Tiptronic eight reports.

History to justify prices that will probably always salty, the Bavarian manufacturer offers, including equipment, a transverse locking ESP electronic controller or a Audi Drive Select, which adjusts the suspension according to four modes: comfort, auto , dynamic and individualistic.

Audi tradition requires, the cabin again plays the card of refinement with a center console that showcases technology and infotainment. Thus, the large hard drive with eight-inch screen can be controlled using the touch pad while for the HiFi system, the customer can opt for the Advanced Sound System from Bang & Olufsen with 15 speakers.
