A New Electronically Controlled Injection Pump for Diesels

An electronically controlled rotary-type diesel fuel injection pump has been developed to provide full authority fuel and timing control for light-duty diesel engines in automotive, agricultural and industrial engine applications.

Vehicle testing to date on a 4.3 liter V-6 and a 6.2 liter V-8 diesel engine has resulted in obtaining superior performance in several areas when compared with engines equipped with their original mechanical fuel injection pumps.

An eight-bit single chip microcomputer, and linear stepper motors, along with engine and vehicle mounted sensors provide the full authority electronic control functions.
