ABSTRACT:
An electronically controlled fuel-injection system for an internal combustion engine, wherein fuel injection control pulses drive associated fuel injectors for delivering fuel to the internal combustion engine. A fuel pump delivers fuel from an associated fuel tank to the fuel injectors and a pressure regulator associated with the fuel tank maintains a pressure differential across the fuel injectors. Exhaust back pressure from the internal combustion engine is applied to the pressure regulator, such that the pressure differential across the fuel injectors varies in response to pressure changes in exhaust back pressure. A linear relationship between exhaust back pressure and the pressure differential across the fuel injectors provides an inexpensive and accurate electronic fuel injection control system.
