摘要： Disclosed is a method for controlling fuel injection for an engine, in which, on the basis of a phenomenon that a part of fuel vaporized from a liquid film adhering to a wall surface of a fuel intake manifold remains in the intake manifold in the form of vapor fuel, the quantity of liquid film and the quantity of vapor fuel are estimated by using control parameters such as air mass flowing through a throttle valve, throttle opening, engine speed, air fuel ratio, etc.; the quantity of liquid film and the quantity of vapor fuel at a desired point of time are predicted on the basis of the result of estimation; and the quantity of fuel injection is controlled so as to make the air fuel ratio be a desired air fuel ratio. Further, the quantity of liquid film is estimated in the case where the data as to the air fuel ratio obtained by an O.sub.2 sensor includes an observation delay; a sum of the quantity of fuel vaporized from a liquid film at a desired point of time and the quantity of fuel which does not adhere to a wall surface of an intake manifold is predicted on the basis of the result of the estimation; and the quantity of fuel injection is controlled so as to make the observed air fuel ratio be a desired air fuel ratio on the assumption that the quantity of fuel corresponding to the estimated sum is sucked into a cylinder.

摘要： An adaptive control system for categorized engine conditions is disclosed in which the engine conditions to be controlled are discriminated and classified in accordance with the driver's intent and the vehicle operating conditions. It is decided that a given engine control condition is continued or the transition is under way between different control conditions as a history judgement, and a vehicle operation parameter is determined in accordance with the determined history. At the same time, in accordance with the control condition decided and classified, an operating signal is applied to the engine with an operating parameter thus determined and the result of engine control response is observed to update the adaptive parameter.
