摘要： The method for purifying combustion exhaust gas according to the present invention utilizes a NH.sub.3 decomposing catalyst. The NH.sub.3 decomposing catalyst in the present invention is capable of converting substantially all of the NH.sub.3 in the combustion exhaust gas to N.sub.2 when the air-fuel ratio of the exhaust gas is lean and the temperature of the catalyst is within a predetermined optimum temperature range. Further, when the exhaust gas contains NO.sub.x in addition to NH.sub.3, the NH.sub.3 decomposing catalyst is capable of reducing the NO.sub.x in the optimum temperature range even though the air-fuel ratio of the exhaust gas is lean. In the present invention, the conditions of the exhaust gas containing NO.sub.x are adjusted before it is fed to the NH.sub.3 decomposing catalyst in such a manner that the temperature of the exhaust gas is within the optimum temperature range and the air-fuel ratio of the exhaust gas is lean. Further, NH.sub.3 is added to the exhaust gas before it is fed to the NH.sub.3 decomposing catalyst. Therefore, a lean air-fuel ratio exhaust gas, at a temperature within the optimum temperature range, which contains both the NO.sub.x and NH.sub.3 is fed to the NH.sub.3 decomposing catalyst, and the NO.sub.x, as well as the NH.sub.3, in the exhaust gas is completely resolved by the NH.sub.3 decomposing catalyst.

摘要： A supercharged internal combustion engine is provided with a turbo supercharger mounted on an intake pipe and driven by engine exhaust gases to produce a pressurized intake air to be fed into the engine. A bypass intake pipe branches out of the intake pipe upstream of the supercharger and merges into the intake pipe at a point downstream of the supercharger. A first valve member is disposed in the intake pipe adjacent to the merging point to control the communication between the intake pipe and the bypass intake pipe and the communication between the upstream part of the intake pipe and the downstream part of the intake pipe. A first and second air release ports are formed in the intake pipe, one of which is disposed between the supercharger and the merging point and the other is disposed downstream of the merging point. Second and third valve members are provided to open and close the first and second air release ports, respectively. The first and second valve members are pneumatically actuated in accordance with the variation in the engine intake manifold pressure, whereas the third valve member is moved to its open position when the pressure in the intake pipe downstream of the merging point exceeds a predetermined level.

摘要： An idling speed control device normally controlling the idling speed of the engine so that it becomes equal to a desired idling speed. At the time of acceleration, the lean time and the rich time of the air-fuel mixture are calculated during the lean-rich discriminating time, which is basically equal to a time of an occurrence of the lean time and the rich time when the air-fuel ratio is maintained at the stoichiometric air-fuel ratio at the time of acceleration. If the lean time becomes considerably longer than the rich time when the engine is started, the idling speed is increased.

摘要： A hydraulic valve lift device for transmitting the motion of a cam to a push rod of an intake or exhaust valve of an engine, including a housing, a lifter slidably engaged by the housing and provided therein with an oil pressure chamber adapted to receive an oil, and a plunger provided with a flange portion and slidable in relation to the lifter. The flange portion of the plunger and cylindrical bore of the housing cooperate with each other to define therebetween a braking chamber into which oil is introduced. The device has a slit through which the oil in the braking chamber is relieved to the outside. The arrangement is such that the rate of oil relieved through the braking chamber is reduced as the plunger is lowered. The device further includes a relief valve for maintaining the pressure in the braking chamber below a predetermined pressure level.

摘要： A fuel injection system for an internal combustion engine has an air sensor for metering the intake air flow into the engine and a fuel metering and distributing device hydraulically coupled together. The device includes a plunger rotated by the engine to distribute fuel to respective fuel injectors and axially moved in response to variation in the intake air flow rate to meter the fuel. The axial displacement of the plunger is determined by two opposing hydraulic pressures acting on the opposite ends of the plunger, one of which is varied in accordance with the engine intake air flow rate as detected by the air sensor while the other hydraulic pressure is changed in accordance with the axial displacement of the plunger. Since no mechanical linkage is required between the air sensor and the fuel metering and distributing device, the system can easily be installed in a limited space and, in addition, assure an improvement in the accuracy of the fuel control.

摘要： A fuel injection control device in which it is determined whether the air-fuel mixture is lean or rich at a predetermined crankangle during a lean-rich discriminating time at the time of acceleration. The lean-rich discriminating time is shortened as the degree of the acceleration becomes larger, and the times of being lean and the times of being rich within the lean-rich discriminating time are calculated. When the times of being lean are larger than the times of being rich, and the difference therebetween is larger than a predetermined value, the accelerating increasing rate of the amount of fuel fed into the engine cylinder is increased.
