1.3 Diesel Engine Electronic Control technology development trends

1.3.1 high-pressure spray

To meet the requirements of emissions regulations, diesel fuel injection pressure from 10 MPa to 200 MPa. The high pressure spray can improve the mix of diesel and air quality, shorten the period of delay on fire, burning more rapidly and thoroughly, and the control of combustion temperature, thereby reducing emissions.

1.3.2 independent injection pressure control

The traditional diesel engine fuel injection system of the jet engine pressure and the speed of the load. Such characteristics of the low-speed, under the conditions of the partial load fuel economy and emissions disadvantage. If the oil supply system is not dependent on speed and load the injection pressure control, you can select the most suitable injection pressure to spray duration, delayed ignition of the best, so that diesel engines in various condition of the economy and the lowest emission of optimal .

1.3.3 improve diesel fuel economy

Users of diesel fuel consumption rate of great concern. High-pressure jet, an independent injection pressure control, small nozzle, the average high-pressure fuel injection and other measures can reduce fuel consumption, thereby enhancing the use of diesel fuel economy.
