D. TURBOCHARGER (8454)
The mechanism of turbocharger is the use of exhaust
gas energy which rotates turbine and the power is
transmitted to air compressor by a shaft. So it is pos-
sible to supply more fuel to a cylinders and this will
increase the power.
It is recommended not to accelerate suddenly just about
starting or stopping the engine suddenly after driving.
Since the turbocharger runs above 100,000 rpm it is
necessary to allow the engine to idle for 1 or 2 minutes
before stopping, this protect the bearings of the turbo-
charger.
To keep a capacity of turbocharger you should check
the engine oil and air cleaner periodically. Turbocharger
is composed of precision parts. Do not disassemble
or repair without permission.
Turbocharger actuator pressure is 460 mmHg.
The structure of turbocharger is as above.
