摘要： PURPOSE: To improve performance of an engine, by controlling fuel injection valves provided one for each cylinder by selecting either one from three injection methods, i.e., independent, group and simultaneous injection methods according to the operational conditions of the engine.
CONSTITUTION: During the operation of an engine, load region of the engine 1 is detected from the outputs of a crank angle sensor 9 and a suction pressure sensor 15 by means of a control unit 8. In case that it is judged that the engine 1 is operated in its low-load region, "independent injection" is effected, that is, injection is effected once during one suction stroke independently for each cylinder. On the other hand, in case that it is judged that the engine is operated in its medium-load region, "group injection" is effected, that is, injection is effected once during one suction stroke by separating the cylinders into two groups (in case of six cylinders, for instance, the cylinders are separated into a first group of cylinders #1, #5, #3 and a second group of cylinders #6, #2, #4). Further, in case that the engine operation is in its high-load region, "simultaneous injection" is effected, that is, simultaneous injection is effected twice during one suction stroke by dividing the suction stroke into the first half and the latter half.

摘要： PURPOSE: To constantly maintain to optimum ignition timing for an internal combustion engine by calculating the basic ignition time submitting it for rectification with compensation data memorized as to the engine's driving condition thus to find out the right ignition timing.
CONSTITUTION: The system is to control the ignition timing of an ignition device 2 of the internal combustion engine 1. The computor 4 detects the engine condition from the output of both air-inlet pressure sensor 5 and revolution angle sensor 6 to calculate the them optimum ignition time. At this time, the engine driving condition is judged as for whether it is running on the steady state for a set period. If it is on the steady state, a comparison of a detected signal of the engine's driving condition with another detected signal obtained prior to the set period is to be carried out to obtain the ignition timing of increased revolution. According to the result of this judgement, the compensation data stored in the memory of the computor 4 is rectified to the above ignition timing thus to correct the ignition timing with the rectified data.

摘要： PURPOSE:To omit an occupying space for a detecting circuit, by constituting a local flow rate sensor and the detecting circuit as different bodies, attaching the local flow rate sensor to a throttle body, and attaching the detecting circuit to a body mounting member. CONSTITUTION:An HW sensor 5 as a local flow rate sensor is located at the upstream side of a throttle valve 3 and also in the vicinity of the throttle valve 3. When the throttle valve 3 is rotated in the direction of an arrow A with respect to a central axis 0-0 of an intake air path 2, the throttle valve 3 is moved farther from the sensor. The sensor is deviated upward from the central axis 0-0. Said HW sensor 5 is fixed to a throttle body 1 through a fixing tool 7 made of Bakelite and the like. The fixing tool 7 prevents the intrusion of external air through the gap between the HW sensor 5 and the throttle body 1. The detecting circuit is electrically connected to the HW sensor 5 through a lead wire 8. The detecting circuit 6 is attached to a body 9 and the like.

摘要： PURPOSE:To control firing timing or fuel feeding more accurately by providing a cylinder inner pressure sensor for detecting pressure in combustion chamber directly thereby detecting the state of cylinder inner pressure immediately after closing of suction valve or state during combustion. CONSTITUTION:A pressure sensor 11 for detecting the pressure in combustion chamber of an internal-combustion engine and a rotary angle sensor 13 for detecting the crank angle position are provided to calculate suction air amount from a map or basic formula through said pressure sensor 11 while knocking or limit pressure setting based on pressure variation in cylinder is detected to control firing timing or fuel feed on the basis of said signal. Consequently various factors in suction system (such as difference of negative pressure production due to manifold shape) are eliminated to enable measurement of level nearer to true air amount. Conventional suction air amount sensor, firing timing control knocking sensor can be realized with single cylinder inner pressure sensor resulting in highly accurate control.
