摘要： A valve operation control system in an internal combustion engine, comprising an engine valve openably and closably supported on an engine body, a valve spring for biasing the engine valve in a valve closing direction, and valve driving means interposed between a valve-operating cam and the engine valve to transmit a force in the valve-opening direction provided by the valve-operating cam to the engine valve. The valve driving means includes a valve-opening resilient member for exhibiting a repulsive force in a direction to open the engine valve, and closed-position retaining means is interposed between the engine valve and the valve operating cam for retaining the engine valve at its closed position, with a valve-opening force provided by the valve-operating cam being accumulated by the valve-opening resilient member. The closed-position retaining means is arranged to be switchable between a retaining state and a releasing state to control the timing of opening the engine valve depending upon the operational condition of the engine.

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： An automatic choke valve apparatus for an internal combustion engine in which an operation shaft connected to a choke valve provided in an intake passage of an internal combustion engine and a driving shaft connected to a pulse motor are connected together through an intermediate torsion spring and are engaged with one another through circumferentially disposed front and rear pawls for being feed-driven only in regular direction of rotation of the driving shaft. The choke valve is given a starting position setting in such manner that, by the operation of the pulse motor, the driving shaft undergoes excessive rotation beyond the fully closed position of the choke valve. A fast-idle cam cooperating with a throttle valve provided in the intake passage is angularly extended in one direction so as to form a low temperature cam portion comparatively large in cam height and the fast idle cam is connected to the driving shaft through a gang mechanism such as a link, so that in the course of excessive rotation of the driving shaft, the cam undergoes excessive rotation corresponding thereto and the low temperature cam portion is placed into operating position.

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.
