The Delphi DP310 Rotary Mechanical Diesel Fuel Injection Pump is based on the Delphi DP210 Series. It is a viable alternative to electronic control for diesel engine applications up to approximately 129 kW that must meet EU Stage 3A, U.S. Tier III and equivalent emissions standards. The DP310 Injection Pump’s performance capability includes improved injection timing control, enhanced fuel/torque curve shaping and improved pump-to-pump timing.
The main components of the DP310
Injection Pump include:
The Delphi DP310 Rotary Mechanical Diesel Fuel Injection Pump is suitable for three-, four- and six-cylinder engines in off-highway applications. It can be used in naturally aspirated and turbocharged engines, with or without charge air cooling.
The basic operating principal of the Delphi DP310 Rotary Mechanical Diesel Fuel Injection Pump is the same as the highly successful Delphi DP200, DPS and DPA fuel injection pumps. Fuel enters the pump and is raised to a pressure of up to six bar for proper control of fuel quantity and timing. Between injections, fuel is fed through a control (metering) valve into the distributor rotor center. At full fuel, the valve is held open and the pump delivers maximum fuel quantity. It is regulated by the maximum displacement of the pumping plungers and controlled by movable scroll plates. A maximum fuel curve shaping device (torque trimmer) is designed specifically for each engine application to optimize fuel delivery at any engine speed. At lower engine loads, fuel is controlled via the governor, which throttles filling of the pump. During the pumping phase, the plungers are forced inward causing an injection pulse to travel from the pump to the injector in the engine cylinder via the delivery valve and high pressure pipe. Timing of the injection is controlled or altered by rotation of the cam relative to the pumping plungers and drive shaft.
