Filed: 1991-12-27
Abstract: PURPOSE:To remove a noise component so as to improve accuracy of detecting a misfire by providing high and low pass filters as filter means, and filtering a frequency in accordance with an engine speed region. CONSTITUTION:An electronic control unit 5 contains an engine speed detecting means, filter means, engine speed fluctuating amount calculating means, mifire deciding means, etc. High and low pass filters, which output only a specific frequency band of the speed region of an engine 1 by these means 5, are provided. The filters are switched in accordance with the engine speed region so as to use the high pass filter, when the engine is at a low speed, and the low pass filter when the engine is at a high speed. A misfire is decided by correcting a misfire decision value decreased or by correcting an engine speed fluctuating amount increased, in accordance with an output frequency band of the filter. In this way, high accurate detection of the misfire can be performed in no relation to an operating condition of the engine 1.

The tip of a claw member 40 of the socket 3 has such a locking shape as to be narrowed by an annular spring 45. A cam 60 formed on the inner peripheral surface of a rotational operating cylinder 50 applies no operating force to the rear end of the claw member at the original position of the cylinder 50 but applies operating force to the rear end of the claw member at the operating position to extend the tip. The cylinder 50 is energized to the original position by the spring. A groove 18 is formed on the outer peripheral surface of the plug 2. The plug 2 is inserted into the socket 3. The valve elements 12, 32 are moved to communicate both joints with each other, and the claw member is engaged with the groove 18 to mechanically connect both joints to each other.  When the rotational operating cylinder is rotated in the connected state, the cam pushes the rear end 43 of the claw member, and the claw member is opened and removed from the groove of the plug. Both joints can be connected by single operation only by inserting the plug into the socket and can be separated by single operation only by rotating the rotational operating cylinder.
