2. Necessity of adjusting nozzle opening pressure
For the injection nozzle, the nozzle opening timing varies according to the nozzle needle opening pressure. If the injection nozzle does not open or Read more Fuel System of Diesel Engine 2 of 2
Fuel System of Diesel Engine 1 of 2
The fuel system delivers the fuel to the engine. The injection pump is driven by the timing belt or the timing gear of engine.
HINT:
The injection pump is driven by the camshaft in accordance with Read more Fuel System of Diesel Engine 1 of 2
Diesel Engine Lubrication System
The lubrication system of a diesel engine is basically the same as that of a gasoline engine. The diesel engine uses a specially-designed oil filter because it generates more carbon particles during combustion Read more Diesel Engine Lubrication System
Diesel Engine Valve Mechanism
1. Four-valve mechanism
The valve mechanism of the diesel engine is basically the same as the one on the gasoline engine. However, some valve mechanisms are distinctive to the engine. The four-valve Read more Diesel Engine Valve Mechanism
Diesel Engine Cylinder Head Gasket
The cylinder head gasket is mounted between the cylinder block and the cylinder head. It prevents combustion gasses, coolant and oil from leaking out between the cylinder block and the cylinder head. This Read more Diesel Engine Cylinder Head Gasket

Diesel Engine Combustion Chamber
In a diesel engine, the fuel is injected as mist from the injection nozzle and mixed with the air and is ignited and burned. To obtain good combustion, it is necessary Read more Diesel Engine Proper 2 of 2
Diesel Engine Proper 1 of 2
Piston
The piston of the diesel engine is made to be strong because the compression pressure, combustion temperature and combustion pressure are higher than that of the gasoline engine. In some models, Read more Diesel Engine Proper 1 of 2
Maintaining the proper coolant temperature (Diesel Engine).
Maintaining the proper fuel injection timing, injection pressure and spraying condition.
1. Comparison between diesel knock and gasoline knocking
Diesel knock and gasoline knocking both have a sudden Read more Maintaining the proper coolant temperature (Diesel Engine).
What is Diesel Knock and Gasoline Knock ?
The fuel accumulated during the ignition delay period is burned at one time during the flame propagation period. Thus the pressure inside the combustion chamber rises sharply. The pressure inside the combustion Read more What is Diesel Knock and Gasoline Knock ?
Diesel Engine Output Control
In a diesel engine, fuel is injected after the air is compressed and becomes high temperature and pressure. To obtain a high compression pressure even at low engine speeds, a large amount of air must be Read more Diesel Engine Output Control
