摘要

A method for computing the quantity of injected fuel for an automobile engine equipped with an electronically controlled fuel injection system and an apparatus for detecting an exchange period for lubricating oils and constitutional parts are capable of informing a driver of an exchange period for an engine oil per use of a proper fuel quantity by calculating a total of the accumulated quantity of injected fuel for the automobile engine equipped with the electronically controlled fuel injection system.
