Abstract
A fuel controller for an internal combustion engine has a microprocessor which calculates the air intake rate per cylinder per suction stroke of the engine. The microprocessor detects misfiring when the air intake rate undergoes a large increase, due to a fall in enginie rotational speed caused by misfiring. The microprocessor prevents the fuel injector of a misfiring cylinder from supplying fuel to the misfiring cylinder.
