Abstract: An abnormal combustion detection apparatus for an internal combustion engine quickly detects the occurrence of preignition by using a knock sensor. When the knock sensor detects an engine knocking, the ignition timing is delayed. If despite the delay of ignition timing, the knocking is not decreased and the air-fuel ratio detected after the delay of ignition timing is less than the air-fuel ratio detected before the delay of ignition timing, it is determined that preignition has occurred.

Abstract: A filter for an air cleaner is produced by impregnating a fiber web composed of one or more layers with a liquid binder in the form of solution, suspension, or emulsion. The impregnated fiber web is dried such that the solvent or dispersing medium on one side evaporates faster then that on the other side. As the result, more binder is deposited on one side than on the other side; in other words, a gradient of binder distribution is formed. The thus-produced filter has such a structure that the voids among fibers continuously change across the thickness, while fibers are bonded together by the binder. The filter thus produced can collect more dust than a conventional one.

A first rotating body is connected to one end of a driving shaft of an engine coaxially, and an annular second rotating body is disposed around a boss which projects from the center of the first rotating body so as to be coaxial and parallel with the first rotating body.

Abstract: In an internal combustion engine, a standard deviation of combustion variations generated for every firing stroke of at least one cylinder is calculated. The misfire limit of the engine is detected by determining whether or not the calculated standard deviation is greater than a reference value. When the calculated standard deviation is greater than the reference value, the controlled air-fuel ratio is decreased, while when the calculated standard deviation is not greater than the reference value, the controlled air-fuel ratio is increased, thereby attaining a lean burn system without a lean mixture sensor.
