Electronic Control Pump Nozzle Fuel System Diesel Generators

There are two methods for diesel generators to achieve electronic control of fuel injection: one is to improve the electronic control of the speed controller and fuel injector on the basis of the traditional fuel injection pump oil pipe nozzle system; The second is to adopt a new fuel injection concept, which directly controls the fuel injectors.

Electronic control pump nozzle technology is a way of directly integrating all functions of fuel pressure increase, timing, and fuel quantity control onto the cylinder head of a diesel engine. The main design principle of this system is to directly drive the fuel pump to form high pressure through the overhead camshaft at the top of the cylinder.

Due to the absence of additional high-pressure fuel pipelines, pressure loss in the pipelines is eliminated and the possibility of pipeline leakage is avoided. Due to the integration of fuel boosting and injection devices, fuel injection can be completed efficiently and under high pressure in a short period of time, with flexible control of fuel injection quantity, pressure, and timing, and the injection pressure exceeds the level that can be achieved by common rail fuel systems and single pump fuel systems.

But this structure requires the diesel generator to design a cylinder head overhead camshaft structure to increase the stiffness and strength of the cylinder head. Based on foreign product experience, diesel engines designed with this design generally need to withstand a maximum burst pressure of 20MPa in the cylinder. Its advantage is that it can generate higher injection pressure and directly transition to domestic IV and V products. Of course, the entire machine is generally designed to meet the potential for upgrading national IV and V emissions.

The electronic control pump nozzle fuel system has practical application in domestic Bora system diesel cars. In the future, diesel generators need to continuously increase injection pressure, as increasing injection pressure is an effective means to reduce fuel consumption and exhaust pollution in diesel engines, and improve their performance. The electronic control pump nozzle system can achieve high injection pressure and accurately control the injection quantity and timing, which is a new trend in the development of diesel generator fuel injection devices.
