ABSTRACT:
A fuel injection system for an internal combustion engine is provided wherein fuel supply compensation for low speed, low load or abnormal conditions is variable for a multi-cylinder configuration having one or more cylinders ceased or reduced in operation. Of particular utility in a vertical cylinder bank with compact space for exhaust gas collection and discharge, such as in an outboard motor, said fuel compensation relies upon engine parameters including engine speed and fuel-air ratio to improve engine performance.
