摘要： An ignition timing control system for an internal combustion controls the ignition timing in dependence upon an indicative pressure signal representing changes of the inner pressure within the combustion chamber of the engine. The ignition timing control system ceases the feed-back control based on the indicative pressure signal but performs an open loop control under predetermined engine operational conditions.

摘要： A reverse drive for small vehicles in which an output shaft of a second motor, which is different from the internal combustion engine for running use, can be connected to the transmission line leading from the internal combustion engine to the rear wheel so as to rotate the rear wheel in reverse. The second motor is a starter motor capable of normal and reverse rotations, the normal rotation of the starter motor being transmitted to the internal combustion engine for driving use through a starting clutch, and the reverse rotation of said starter motor being transmitted to the power transmission line through a reverse clutch. Otherwise, the second motor may be a starter motor capable of rotating only in one direction. In this case, the output of the starter motor is transmitted to the output side of the power transmission line through a reverse transmission line while the output transmission line is interrupted.

摘要： An engine ignition system connected between an engine crank and ignition coils includes a reference position signal generating device having reference position sensors, and a crank angle sensing device. The ignition system also includes a signal processing device which receives both the reference position signals and crank angle signals, and when one of the reference position signals is absent continues to generate ignition control signals which activate the ignition coils. The signal processing device includes a counter which counts the crank angle signals and which is reset by the reference position signals, and a decoder which produces a signal when a count value reaches a predetermined count. The signal processing device also includes a logic circuit and a flip-flop for producing either primary ignition control signals or replacement ignition control signals. The replacement ignition control signals are generated when one of the reference position signals is absent.

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.
