Rotary Fuel Injection Pump Developments for High Speed Diesel Engines

The paper describes the new features being introduced to the Lucas CAV rotary fuel injection pump product range to meet current market demands. The introduction of an external means of setting the maximum fuel on the traditional rotary pump forms the basis of the new design described in the paper, which also gives the options of excess fuel, boost and torque control. Demands from the diesel engine designer will continue to advance with the advent of increasingly severe emissions legislation. The paper describes future developments to optimise fuel metering and injection timing controls by employing microprocessors to control a rotary distributor pump electronically.
