摘要： A combustion state detector apparatus for an internal combustion engine has a current detection device for detecting a current flowing between the ignition plug and a ground, and an ignition driving device for driving the ignition plug on the basis of an ignition instruction signal from an electronic control device of the internal combustion engine. An independent unit including a current detection device and an ignition driving device, is provided for each cylinder of the internal combustion engine. With respect to each cylinder, the apparatus determines whether a misfire has occurred on the basis of the current flowing between the ignition plug and the ground at the time of combustion. The apparatus is also capable of detecting abnormalities and/or wire breakages in a signal system provided for signal transmission between each independent unit and the electronic control device of the internal combustion engine.

摘要： A method and an apparatus in which an engine is controlled by a microcomputer on the basis of a basic ignition advanced angle, an ignition advanced angle unit-correction value and a supplied air quantity unit-correction value stored in maps for providing a best fuel consumption corresponding to each of various running conditions such as an intake air quantity, engine revolution number, and the like, as well as on the basis of correction factors corresponding to running conditions such as stable running and unstable running. In order to obtain a best fuel consumption in a stable running state, the ignition advanced angle and the supplied air quantity are parallelly corrected by the ignition advanced angle unit-correction value and the supplied air quantity unit-correction value respectively while discriminating increment of torque so that this correction is successively repeated until a best fuel consumption is reached. The ignition advanced angle correction factors and the air quantity correction factors are stored, updating the previously stored data, on the basis of the respective total correction values searched by the successively repeated corrections.

摘要： In an ignition timing control apparatus for controlling the ignition timing of each cylinder in order to reduce knock generation in a multi-cylinder engine, a lag-angle correction is made for the ignition timing of a cylinder in which a knock is generated and at the same time, a slight lag-angle correction is made for the ignition timing of the other cylinders in which no knock is generated. When the operating condition of engine is rapidly changed for example, under the condition in which knock is liable to occur in all cylinders as at rapid acceleration time, a lag-angle correction is made by the same amount as in the knock generating cylinder, for the ignition timing of cylinders in which no knock is generated. When no knock is generated for a predetermined time, a lead-angle correction is made for the ignition timing subjected to the lag-angle correction of each cylinder at intervals of the predetermined time.

摘要： A seat belt system for a vehicle including an impact energy absorbing device mounted between a seat belt for restraining an occupant and a seat belt anchor means. The impact energy absorbing device includes a cutter, a member disposed in juxtaposed relation to the cutter and adapted to be sheared by the cutter as the member and the cutter move relative to each other, and a cutter supporting member to which the cutter is securely fixed. When the vehicle collides, the impact energy is absorbed by the shearing of the member by the cutter. The shearing load exerted on the member may vary depending on the tension speed exerted on the seat belt at the time of collision, so that the movement of the occupant caused by the collision can be confined to a substantially constant range at varying collision velocities and a secondary collision of the occupant against an instrument panel or the like can be prevented.

摘要： A seat belt retracting and winding device of the type including spring means including first and second springs imparting a torque to the winding shaft so as to retract the seat belt wound therearound, and control means for changing the torque applied to said winding shaft by the spring means depending upon whether an occupant fastens the seat belt and is restrained by the tension thereof or the occupant releases the seat belt so that the latter is being wound. Securely retaining the outer end or the other end of the second spring is disclosed. To ensure more reliable and dependable operation of the control means, a pawl included in the control means has an improved shape at the engaging end thereof and is positively prevented from the displacement in the direction of the axis of its pivot pin. Thirdly, erratic assembly of a friction disk and a cam disk of the control means may be avoided by the improved designs thereof. Fourthly, when the seat belt is retracted and rewound, the engagement of the pawl with the cam disk may be completely prevented so that damage to the device may be prevented and consequently reliable and dependable operation may be ensured. Finally, the axial movement of the first spring may be prevented, and therefore, the satisfactory operation of the device may be ensured.
