    Abstract: An ignition timing control system and method for a vehiclular internal combustion engine which effectively avoids an occurrence of engine knocking and improves engine performance. In the ignition timing control system and method, the engine knocking is predicted which will occur when an engine operating state becomes a high load due to an abrupt change in an engine revolutional speed. While the engine knocking is predicted, a correction amount (K.Y, K.X) for a retardation angle correction amount (SA.sub.ri) is increased with the correction coefficient set to a large multiple so that a correction for the ignition timing is carried out at a more earlier stage to avoid the occurrence of knocking.

    Abstract: A system and method for controlling the ignition timing of an internal combustion engine, in which a predetermined transient state which increase the probability of engine knocking is detected, a basic ignition advance angle value determined by an engine operating condition is corrected by a retardation angle value which is stored when knocking is suppressed during the predetermined transient state and is returned quickly toward the basic advance angle while ensuring that engine knocking will not recur after the predetermined transient state is over.

    Abstract: A method and apparatus for the control of the air-fuel ratio of a mixture to an internal combustion engine. A value of fuel-delivery requirement for the engine is determined based upon engine load. An engine crankshaft position at which the pressure in each cylinder is at maximum is detected during each data sampling cycle. The determined fuel-delivery requirement value is modified based upon the detected engine crankshaft position.

    Abstract: A back-up system for an engine coolant temperature sensor detects deviation of the output of the temperature sensor from its designed output range to produce a fault signal. In response to the fault signal, an engine control system derives the engine coolant temperature indirectly from other engine conditions. This derivation is based on two facts: (1) the amount of fuel required to start the engine is related to engine temperature, and (2) since the calorific value of a given engine is essentially constant, the rate of increase of engine temperature is related to the integrated number of engine revolutions. Thus, when the engine is to be started, engine temperature can be derived by gradually increasing the fuel supply quantity from a minimal initial value until the engine is able to start to determine the required fuel supply quantity. Thereafter, the derived temperature value can be updated as a function of total engine revolutions.

    Abstract: In a method of supplying fuel to an internal combustion engine during start-up, the occurence of combustion is detected to arrest the change of the fuel supply quantity until steady-state engine operation is achieved. Combustion is detected by comparing sensed engine speed to a minimum engine speed resulting from combustion in the cylinders. Additionally, control values used to derive the start-up fuel quantity are modified so that the fuel quantity increases monotonically from a relatively low initial value until fuel ignition is detected.
