摘要： A fuel injection control system performs fuel cut-off operation intermittently so that engine output torque may not fluctuate at significant level to cause jerking at the transition from fuel injecting state to fuel to fuel cut-off state and at fuel resumption after fuel cut-off. Intermittnetly cutting off the fuel delivery for the engine cylinders, engine output torque drop at the fuel injecting state and fuel cut-off state can be reduced for reducing magnitude of jerking.

摘要： An apparatus for controlling an internal combustion engine having a plurality of cylinders and fuel injectors provided to inject fuel in a sequential fashion for the respective cylinders. Fuel injection is made twice from a given fuel injector. The control circuit calculates a first value for the amount of fuel injected from the fuel injector during the first fuel injection and a second value for the amount of fuel injected from the fuel injector during the second fuel injection. During transition of the engine operation, an engine load variation is produced between the times at which the first and second values are calculated. A correction factor is calculated based on the engine load variation with an estimation of a first value to be calculated for the cylinder when the fuel injected during the first and second fuel injections is charged in the cylinder.

摘要： In order to compensate for the effect of a by-pass passage which by-passes air about the engine throttle valve when a predetermined vacuum prevails downstream thereof, or the delay in air flow within the induction system in response to the demand for engine power, a target torque value is derived based on the engine speed and the accelerator pedal depression amount and this value is used in connection with one or both of the fuel supply and the air flow control. In some embodiments two basic injection pulses are developed and one is selected to suit the instant induction conditions. In other embodiments, selectively delayed target torque values are used to individually modify the throttle valve control and injection fuel supply amount.

摘要： A system and method for controlling an ignition timing for an internal combustion engine mounted in a vehicle are disclosed in which a limit value for the ignition timing value is provided so that a difference between a current ignition timing and a previous ignition timing is within the limit value and the limit value is set according to a magnitude of an engine acceleration. For example, when an abrupt engine acceleration occurs, the limit value is set to 15 degrees. When the engine is in a steady state (no abrupt acceleration from an idling condition), the limit value is set to four degrees. Therefore, no vehicle body shock occurs due to the abrupt change in an engine output torque caused by the abrupt change in the ignition timing and a response characteristic of a rise in the engine output torque during the abrupt acceleration can be assured.

摘要： A fuel injection control system derives a target fuel amount to be introduced into a combustion chamber of an internal combustion engine in each induction stroke in the engine revolution cycle, according to an engine driving condition for establishing a desired air/fuel ratio of an air/fuel mixture in the combustion chamber. The target fuel amount is modified with a fuel transferrring characteristics dependent correction value which is derived as the reverse of a fuel transferring characteristic when the injected fuel amount coincides with the fuel amount introduced into the combustion chamber. The fuel injection amount for actual fuel injection is thus derived so that the injected fuel amount coincides with the modified target fuel amount.
