Diesel Injection Common Rail SystemIn the engine controlled by a camshaft with an axial plunger distributor pump, the fuel system pressure is linearly related to the engine speed, and the fuel pressure is insufficient at low engine speeds, while the common rail system can be used in all engine speed
Ensure high fuel pressure in all engine speed rangesWith the more stringent emission control, higher and constant diesel injection pressure and better electronic control are required, so many manufacturers take advantage of Many diesel common rail systems are the development direction of diesel engi
diesel engines Fuel injection pressure indicator In the past 2 years, cars with direct injection diesel engines have developed significantly in Europe, with high efficiency and excellent fuel economy, and reduced engine noise. The direct injection diesel engine uses a pump nozzle system. The domesti
CP4 structure principle1. Structural drawing2. Drive modeThe driving methods of CP1H, CP3 and Denso HP oil pumps are driven by eccentric wheels, while CP4 is driven by cams. Therefore, each time the camshaft rotates, oil is supplied twice per cylinder, which greatly improves the CP4 pump oil efficie
