A turbocharger is an exhaust gas using the inertia momentum of the engine exhaust to drive a turbine, and a turbine impeller driven coaxial impeller then pressure-fed air, into the cylinder so that pressurized.
1. Turbocharged engine theory
of the engine is by fuel combustion in the cylinder to generate power for power, since the amount of fuel sucked into the cylinder by the input limit air amount, the engine generated power will be limited, if the performance of the engine has been running at its best, and then increase the output power can be increased only by the amount of fuel compressed air into the cylinder more, thereby improving the engine work capacity.
2. Disadvantages turbo engine
Relative advantages pneumatic booster mode which is more stable operating performance.
Relative pneumatic booster / supercharger construction and its principle embodiment is more simple and convenient modification.
· high economic cost.
Motor mounting opposing pressurized pneumatic booster / supercharger low cost, does not require too complicated mounting process, manufacturers / buyer from the mounting of this aspect can be significant cost savings.
relatively low power booster · disadvantages.
and the turbo supercharger, since the motor-vehicle battery power constraints, typically the boost only 12 percentage to 16 percentage increase compared.
· vehicle battery life decreases.
Motor booster will work because the continuous vehicle battery life decreased rapidly.
3. How turbo engine maintenance
* not left the car. After
engine is started, especially in the winter, it should be allowed to idle for a period of time sufficient to allow oil lubricated bearings before the turbocharger rotor high-speed operation.
Therefore, immediately after the start Meng throttle must not prevent damage to the turbocharger seals.
• Do not turn off immediately.
After the high-speed operation of the engine for a long time, then turn off should idle 3-5min.
engine operatingWhen made, some of the oil supplied to the turbocharger rotor bearing lubrication and for cooling.
· kept clean.
time cleaning air filter to prevent dust and other impurities into the high-speed rotation of the compressor impeller, the rotational speed causing instability or increased wear bushings and seals.
· always pay attention to check the functioning of the turbocharger.
before moving, closed car, check connections of each airway tube, to prevent loosening caused by falling turbocharger failure and short circuit of air into the cylinder.
