  • Patent number: 5188082
    Abstract: An electronically controlled fuel injection control system for an automotive internal combustion engine equipped with a hot wire mass air flow sensor to detect an intake air flow amount. The fuel injection control system is comprised of a microcomputer adapted to control the amount of fuel to be injected from a fuel injector mainly in accordance with an engine speed and the intake air flow amount. In the control by the microcomputer, a compensation for time lag is applied onto an intermediate variable which is calculated from the intake air flow amount and used for calculating the fuel injection amount.
