Heavy Duty Fuel Pump for Electronically Controlled Diesel Engines

The need for diesel engines to achieve good fuel economy with low exhaust emissions poses a complex development problem with sometimes conflicting requirements. In order for these to be addressed, there is a need for a flexible high performance fuel system. This paper describes a heavy duty in-line fuel pump designed for electronic control. It is configured to fit class 7 and 8 truck engines, and features high injection pressure with full authority variable timing.
