Turbocharging Indicator Lights
1. Turbocharging indicator lights
The turbocharging indicator lights are built into the combination meter, and inform the driver about operating condition of the turbocharger with green and amber LEDs Read more Turbocharging Indicator Lights
Boost Pressure Control
The turbocharger attains a high output by pumping compressed air into the cylinders. However engine parts will be unable to withstand the explosive force if the boost pressure rises too high. In this case, Read more Boost Pressure Control
Lubrication and Cooling System
1. Lubrication system
Engine oil is supplied from the oil inlet pipe to lubricate and cool the full-floating bearings inside the center housing. After that, the oil passes through the oil outlet pipe Read more Lubrication and Cooling System
How to Increase Fuel Injection Volume
An engine equipped with a turbocharger or supercharger forces a greater volume of air into the cylinder. The power output does not increase until the intake air is burned completely. For this reason, it Read more How to Increase Fuel Injection Volume
What is Turbocharger ?
The turbocharger is a device which uses the energy of the exhaust gas to rotate the turbine wheel at high speeds. There is a compressor wheel on the same shaft as the turbine wheel which compresses air Read more What is Turbocharger ?
Features of Turbocharger and Supercharger
Both the turbocharger and supercharger are a kind of air pump, which force the air into the cylinder to increase the mass of the intake air. The conventional engine draws air in, using the vacuum generated Read more Features of Turbocharger and Supercharger
Necessity of Turbocharger and Supercharger
The turbocharger and supercharger are devices that force air into the cylinders creating a pressure that is greater than the atmospheric pressure in order to increase engine output. Generally, the engine Read more Necessity of Turbocharger and Supercharger
CO/HC Inspection and Adjustment
1. Necessity
Determination of engine condition. By measuring CO/HC, it is possible to determine the engine condition, including the effectiveness of the airfuel ratio, and the operation of the emission Read more CO/HC Inspection and Adjustment
Fuel Evaporative Emission Control (EVAP) System
1. Necessity
The Fuel Evaporative Emission Control (EVAP) System temporarily absorbs the evaporated gas in the charcoal canister and channels it to the engine for burning, in order to prevent the fuel, Read more Fuel Evaporative Emission Control (EVAP) System
