    摘要: An ignition timing control system for an internal combustion chamber includes means for holding a maximum peak position signal of an indicative pressure signal at each engine cycle, means for picking up the held maximum peak position data signal, and means for establishing a suitable ignition angle for keeping the ignition timing to a target optimum ignition timing on the basis of the picked-up maximum peak position signal. The pick-up period is restricted within a narrow crank angle region in which any appreciable level of noises will not be expected in the indicative pressure signal. The narrow crank angle region is defined precisely by counting clock or timing pulses produced therein up to a predetermined number or by supervising the variation in level of the indicative pressure signal.

    摘要: An ignition timing control system for an internal combustion engine which controls the ignition timing for one engine cycle in response to the maximum peak position datum of the indicative pressure signal representing the inner pressure within the combustion chamber during the preceding engine cycle. A misfire detecting means is provided which produces a misfire detection signal upon incomplete combustion in the combustion chamber in an engine cycle. The maximum peak position datum is neglected during the engine cycle in which the misfire detection signal appears. At least one pressure sensor is provided for one cylinder in a group of the cylinders having generally the same charging efficiency or volumetric efficiency.

    摘要: An ignition timing controlling device for an internal combustion engine includes a reference position signal generating circuit for generating a reference position signal each time the rotational angular position of a crank of an internal combustion engine reaches a reference angular position. A pressure indicating signal generating circuit generates a pressure indicating signal indicative of an internal pressure of a combustion chamber of the engine. A peak detecting circuit generates a pressure indicating peak value, a position signal indicative of a maximum peak value and a position of the pressure indicating signal after generation of a reference position signal until generation of a next reference position signal. An ignition instructing circuit is provided for instructing ignition at an ignition angle corresponding to the pressure indicating peak value and the position signal. The ignition instructing circuit delivers an ignition instruction at an ignition timing depending upon a history of change of the pressure indicating peak position while the rate of change of the pressure indicating peak value is low. The ignition instructing circuit delivers an ignition instruction at an ignition timing independent of the pressure indicating peak position when the engine is operating at a low speed and the rate of change of the pressure indicating peak value is high.
