To the public for the pipeline to achieve precise control of hydraulic

To the public for the pipeline to achieve precise control of hydraulic, completely changed the oil pressure with engine speed change phenomenon. Its main features are the following: 1, injection timing and fuel metering completely separate, timely injection pressure and injection process is controlled by the ECU. 2, can be based on engine fuel dispenser pumps operating conditions to adjust each cylinder injection pressure, injection start point, duration, so that the pursuit of optimal control point fuel injection.But with the development of modern technology, these disadvantages diesel are gradually being overcome, and now is not the limousine diesel engines have already started using the.
