Title: Device for controlling opening and closing of solenoid valve
Inventor: TANAKA YUZURU
IPC: F02D41/00
Filed: 1985-10-16
Abstract: PURPOSE:To reduce the pulsatory motion of a solenoid valve by high-frequency duty control within a set range and secure the control range widely by low-frequency duty control in the other range, by providing an electromagnetically opening and closing valve in a fluid passage and performing duty control to the valve. CONSTITUTION:Upon receiving the inhaled air quantity signal of an air flow sensor 8 and engine revolving speed signal of a revolving speed sensor 15, a control unit 14 calculates a fuel injecting quantity and outputs an injection pulse to a fuel injection valve 11 in accordance with the calculated quantity. At the time of idling, the idling revolving speed of an engine is maintained at an almost fixed level by duty-controlling an electromagnetically opening and closing valve 13 in accordance with the engine revolving speed signal. When the idling revolving speed becomes smaller than an aimed revolving speed, the revolving speed of the engine is made higher by enlarging the duty value and increasing the flowing rate of the fuel. When the idling revolving speed becomes higher, on the contrary, the revolving speed of the engine is made lower by making the duty value smaller and decreasing the flowing rate of the fuel.

Inventor: OOISHI MORIKAZU
IPC: F02P5/153
Filed: 1983-12-07
Abstract: PURPOSE:To enable always good ignition control by detecting knocking only when the operating condition of an engine satisfys the judging condition for an octane value, and judging said octane value of the fuel in use. CONSTITUTION:When an engine is operated, judgment is made whether an octane value judging condition is satisfied or not, from the output signals of an engine speed sensor 14, an airflow meter 10, and a cooling water temperature sensor 16, through a control circuit 18. When judged yes, the ignition timing of an engine is changed to the angle of lead for judging octane value, which is further more leading than a required ignition angle of lead for high-octane gasoline. When knocking is detected through a knocking sensor 17 in this condition, judgment is made that the presently using gasoline is a regular gasoline with a lower octane value, and a value in which the value of an engine load (Q/N) multiplied by the difference between the ignition angle of lead for high-octane gasoline and the ignition angle of lead for regular gasoline, and also by a correction factor, is deducted from the ignition timing for high-octane gasoline, is obtained as an ignition timing.
