摘要:
An altitude decision system and engine operating parameter control system using the same for accurately detecting and correcting for altitude uses three signals, viz, the signal from an engine revolution number sensor (52), the signal from a throttle sensor (18) for detecting the angle of opening of a throttle valve (5), and a fundamental fuel injection pulse width signal which is computed by engine operational parameter-computer (51) from inputted signals from a mass air flow sensor (3) and the revolution number detection sensor (52). Having accurately derived the altitude, the fuel injection pulse rate (61), the intake air flow (62) and the ignition timing (63) are corrected.
摘要:
In a multi-cylinder engine control method and a control apparatus therefor, rotational speeds (N e ) of the multi-cylinder engine at explosion strokes of the respective cylinders (1-4) are detected for estimating combustion pressures in the respective cylinders, and deviations of the combustion pressures in the cylinders are derived from the estimated combustion pressures in the respective cylinders, so that ignition timings or fuel amounts supplied to the respective cylinders are regulated in response to the derived deviations of the combustion pressures.
摘要:
The invention relates to a method and a device for controlling the ignition timing of internal combustion engines, wherein the detection processing of the rotational speed (N) of the engine is executed periodically in synchronism with the rotation of the engine. The calculation processing of an ignition timing correction amount (ΔIGN) is executed periodically at predetermined fixed times independently of the rotational speed detection processing. After the engine is accelerated, the ignition timing control of the engine is executed based on the ignition timing correction amount.

An electronic controlled fuel injection system having electromagnetic fuel injection valves (71, 72. 73, 74) each of which injects fuel twice during 4-cycle operation strokes, wherein a reference cylinder (No. 1) is provided to inject fuel at intervals of 360° in crankshaft angle, and the next operating cylinder (No. 3) is made to inject fuel 180° after the fuel injection timing for the reference cylinder.
摘要:
The invention relates to a method and an apparatus for controlling an internal combustion engine in which correction characteristics indicating whether or not various control constants proper or not are calculated through loop control of at least one of operation parameters, such as, an air-fuel ratio, on the basis of air-fuel ratio correction factors subjected to learning to thereby rationalize the control constants such as fundamental injection time so as to realize proper fuel injection and proper ignition timing control.
