What is the difference between the high-pressure pump of high-pressure common rail diesel engine and the traditional high-pressure pump in diesel pressure?

The traditional high-pressure oil pump can only supercharge diesel to about 200 kg, and the opening pressure of the matching nozzle is also 200 kg; * * * The diesel pressure provided by the common rail pump to the * * * common rail pipe is above 1600kg, and the diesel pressure of the new * * * common rail pump reaches 2000kg, which ensures that the fuel injector is turned on and enough diesel oil can be injected into the cylinder in a very short time.
