The Fuel Supply System Of Diesel Engine; The Speed Governing System Of Diesel Engine - Bison BS-20KVA Operation Manual

(2) Supercharged inter-cooler. Select the supercharged inter-cooler in accordance with the air inlet flow
rate and heat taken away by the supercharged air. Under standard environment, the air temperature
getting into the diesel engine through the inter-cooler should be within 45-50℃, which is specified in
the emission requirements. The pressure drop produced by the inter-cooler must not exceed 10kPa.
(3) Exhaust pipe and muffler. The exhaust pipe diameter must be selected in line with the flow rate of
the exhaust air and with the flow rate of the muffler.

8. The fuel supply system of diesel engine

The fuel and speed regulating systems, consisting of fuel supply pump, fuel filter, fuel injection pump,
high and low pressure fuel pipe and fuel injector, are important parts for a diesel engine.
After fuel is pumped into the fuel filter from the fuel tank by the fuel supply pump, it will get into the
fuel injection pump, where a high pressure is produced. Then the fuel will go through the high-pressure
pipe and be sprayed into the combustion chamber by the fuel injector.

9. The speed governing system of diesel engine

According to the speed regulating performance, series diesel engine can offer mechanical governor
and electronic governor to customers.
(1) Mechanical governor
Mechanical centrifugal-type governor is constituted by driving parts, sliding disk, sliding sleeve,
governing spring and speed governing control shaft.
