摘要： A crank angle detecting system for a multicylinder engine includes a disc formed with a large number of slits to detect one-degree crank angular positions and a small number of slits to detect a predetermined piston stroke for each cylinder. Since the widths of a small number of slits are different from each other, it is possible to separately discriminate each cylinder in crank angular position on the basis of the crank angle signals obtained by a large number of slits. In the case where the detecting system is incorporated with a group-ignition system, it is possible to detect a predetermined piston stroke for each cylinder immediately after the engine is started, thus preventing the engine from erroneous ignition.

摘要翻译：用于多缸发动机的曲柄角检测系统包括形成有大量狭缝的盘，以检测一度曲柄角位置和少量狭缝，以检测每个气缸的预定活塞行程。由于少量狭缝的宽度彼此不同，因此可以根据通过大量狭缝获得的曲柄角信号来分别区分曲柄角位置中的每个气缸。在检测系统与组合点火系统并入的情况下，可以在发动机起动之后立即检测每个气缸的预定活塞冲程，从而防止发动机发生错误点火。

摘要： In order to simultaneously prevent engine damage due to violent knocking and maintain good fuel economy, an ignition control system firstly controls the ignition timing according to a first schedule suited for fuel having a first octane rating until the engine enters a preselected mode of operation. At this time the ignition is advanced until knocking occurs. The conditions under which the knocking is generated are compared with prememorized data and if this reveals that the octane value of the fuel is higher than that for which the first schedule is suited control is switched to a second schedule designed for fuel having a second and higher octane value.

摘要： An internal combustion engine has a combustion chamber and an air passage leading to the combustion chamber for conducting air to the combustion chamber. A throttle valve is disposed in the air passage for adjusting the rate of air flow into the combustion chamber. A compressor is disposed in the air passage at a point upstream of the throttle valve for compressing the air. A flow meter is disposed in the air passage at a point upstream of the compressor for sensing the rate of air flow through the air passage. Fuel is injected into the air passage at a point downstream of the throttle valve. The rate of fuel injection normally has a preset relationship with the sensed air flow rate. When the throttle valve is closed, the fuel injection rate is limited to no more than a predetermined level regardless of the preset relationship between the fuel injection rate and the sensed air flow rate. In the case of periodic fuel injection at a frequency proportional to engine speed, the amount of fuel injected during each fuel injection stroke may be limited to a predetermined level when the throttle valve is closed.
