Abstract

A fuel system for an engine (10) has a transducer (16) which supplies an input signal to an electronic fuel control system (15) representing driven demand. A variable gain amplifier (19) modifies the signal applied to the control system and is controlled by a load sensor (20) which detects when a suddenly applied load is placed on the engine such as when an air conditioning compressor (18) is brought into operation when the power output of the alternator (17) is suddenly increased.
