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
Positive Crankcase Ventilation (PCV) System
1. Necessity
Blow-by gas includes a large amount of unburned gas, which leaks out from the gap between the piston ring and cylinder wall into the crankcase. The Positive Crankcase Ventilation (PCV) Read more Positive Crankcase Ventilation (PCV) System
Exhaust Gas Recirculation (EGR) System
1. Necessity
The Exhaust Gas Recirculation (EGR) System recirculates some of the exhaust gases to the intake air system. The flame propagation becomes slow during the combustion when the exhaust gases Read more Exhaust Gas Recirculation (EGR) System
Dash Pot (DP) System
1. Necessity
When the throttle valve closes at high engine speed, a strong vacuum is generated inside the intake manifold. Some of the fuel adhering to the internal walls of the manifold evaporates, Read more Dash Pot (DP) System
