摘要： A device for cancelling annoying sounds caused by operation of an internal combustion engine. An intake sound of the engine, and also a rotational speed of the engine, are obtained. The phase difference between the present intake sound and a desired intake sound is obtained using map data. The map data depends on the rotational speed of the engine and is specifically calculated so that at least the (n+0.5) harmonics (n integer.gtoreq.0) are cancelled. The phase data is used to drive a ceramic speaker or two oppositely directed ceramic speakers, to appropriately compensate the input sound.

摘要： 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.

摘要： 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.

摘要： An air-to-fuel ratio control system, for properly supplying additional air through an additional air passage to the intake port of the internal combustion engine depending on a detected air-to-fuel ratio of the mixture, includes a drive unit having two main pressure chambers divided by a main diaphragm and an auxiliary pressure chamber separated by an auxiliary diaphragm from one of the main chambers. The main and auxiliary diaphragms are connected by a rod to a bypass valve mounted in the additional air passage to increase or decrease the passage area by the movement of the bypass valve. In response to an air-to-fuel ratio detection signal, the intake port vacuum (or the atmosphere) is introduced to either one of the main chamber while the other chamber is occupied with the atmosphere or the intake port vacuum thereby to produce a pressure difference between the two main chambers. Since the third pressure chamber is normally occupied with the intake port vacuum, the movement of the bypass valve is biased in a direction to decrease the passage area of the additional air thereby to eliminate the adverse effect of the variation in the intake port vacuum.

摘要： A combustion monitoring apparatus for an internal combustion engine is provided which is designed to distinguish abnormal combustion conditions from a normal combustion conditions using a combustion ion current included in a current flowing through plug electrodes of a spark plug, resulting from motion of ions between the plug electrodes which are produced by combustion. For example, if a maximum value of the combustion ion current during one combustion cycle is smaller than a given value, it is determined that a misfire has occurred. If an attenuation time from generation of the current flowing through the plug electrodes until a variation in the current is decreased to a given value is shorter than a given time period, it is determined that a flame has been blown out before combustion is completed.

摘要： An exhaust gas purifying apparatus includes a carrier of a honeycomb structure which is made of at least one flat metal plate and at least one corrugated metal plate which is superimposed on the flat metal plate. A catalytic layer is formed on the surface of the carrier. The carrier suited for being coated with the catalytic layer is disposed in an exhaust pipe of an internal combustion engine. The carrier is provided, on an axially intermediate portion thereof, with a large number of louvers which causes a haphazard secondary motion in the exhaust gas. A predetermined portion of the carrier including the turbulence producing portion and an additional region located adjacent to said predetermined region is coated with a larger amount of catalyst than that with which the remaining portion of the carrier is coated, whereby good purifying efficiency can be obtained for a long time.
