摘要： An apparatus for detecting a condition of burning in an internal combustion engine includes a pair of opposed electrodes provided in a combustion chamber of the engine, and an AC voltage applying device for applying an AC voltage between the opposed electrodes. A current detecting device is operative for detecting a current flowing between the opposed electrodes. A current generating means for generating a current-representing signal depending on the detected current, the current generating means having a differentiating circuit for differentiating the AC voltage into the capacitance-current representing signal. In another aspect of this invention, the apparatus further comprises calculating means for calculating ratios between a parameter represented by the burning-ion current representing signal and a parameter represented by a signal depending on the AC voltage applied between the opposed electrodes. A waveform processing device is operative for removing the capacitive current component from the current-representing signal to extract a burning ion current component, and for generating a burning-ion-current representing signal depending on the extracted burning ion current component. The capacitive current component occurs in correspondence with the AC voltage. One aspect of the invention utilizes calculating means for calculating a ratio between a parameter represented by the burning-ion-current representing signal and a parameter represented by a signal depending on the AC voltage applied between opposed electrodes. The burning ion current component corresponds to a burning ion current which flows between the opposed electrodes. A burning condition detecting device is operative for detecting a condition of burning in the combustion chamber of the engine on the basis of the burning-ion-current representing signal generated by the waveform processing device. The waveform processing device includes an integration processing device for integrating the current-representing signal to generate the burning-ion-current representing signal.

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： A combustion monitoring apparatus for an internal combustion engine is provided which includes a voltage supply circuit, a combustion monitoring circuit, and a control circuit. The voltage supply circuit applies the voltage to plug electrodes of a spark plug mounted in a combustion chamber of the engine. The combustion ion monitoring circuit monitors a variation in amount of combustion ions existing between the plug electrodes to determine a combustion condition of the engine based on the current flowing through the plug electrodes produced by application of the voltage to the electrodes. The control circuit controls an operation of the voltage supply circuit so that the voltage is applied across the plug electrodes prior to a discharge duration of a spark plug mounted in the combustion chamber of the engine for monitoring preignition.

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.

摘要： An antidiffusion layer is provided between a first fuel adsorption layer communicated with a fuel tank and a second fuel adsorption layer communicated with air. Since adsorbing ability of the antidiffusion layer is lower than that of the first and second fuel adsorption layers, pore diffusion of the fuel vapor from the first fuel adsorption layer to the second fuel adsorption layer is reduced. Since the antidiffusion layer forms a plurality of nonlinear passages, air diffusion of the fuel vapor is reduced. Therefore, the diffusion of the fuel vapor is suppressed with a thin, small and simple antidiffusion layer, and the canister can be simplified and the reduction of the number of parts and the cost thereof can be realized.

摘要： An evaporative emission control system which may be used in automotive vehicles is disclosed. The evaporative emission control system includes a canister, an inlet passage, a fuel vapor passage, an outlet valve, and an inlet valve. The air inlet passage is exposed at an end to the atmosphere and connected at the other end to the canister for drawing fresh air into the canister. The fuel vapor passage communicates between the canister and a fuel tank. When a pressure in the fuel tank is increased above a given level so that a difference in internal pressure between the fuel tank and the canister reaches a first value, the outlet valve establishes communication between the fuel tank and the canister to allow fuel vapor evaporated within the fuel tank to be drawn into the canister through the fuel vapor passage. Alternatively, when the pressure in the fuel tank is decreased below a given level so that a difference in internal pressure between the fuel tank and the canister reaches a second value, the inlet valve establishes communication between the fuel tank and the canister to allow the air to be drawn into the canister through the air inlet passage. The second value is so determined as to prevent the amount of fuel vapor generated within the fuel tank from being increased above a given value.

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.
