摘要： A fuel injection control device in which the amount of fuel injected by the fuel injector is increased at the time of acceleration. Namely, 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 occurence 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. When the lean time becomes considerably longer than the rich time, the amount of fuel injected by the fuel injector is further increased.

摘要： A fuel injection control device in which the supply of fuel into the engine cylinder is stopped at the time of deceleration, and a rich time of the air-fuel mixture is calculated when the supply of fuel is stopped. If the rich time becomes relatively long, the accelerating increasing rate of the amount of fuel is increased, and if the rich time becomes relatively short, the accelerating increasing rate of the amount of fuel is reduced.

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.

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 PCV system with a check valve device oriented in a vertical direction and including a valve body, a seat member, and a stopper plate. The valve body includes a valve head constructed of elastomer. The seat member includes a valve seat surface on a lower surface thereof. The seat member further includes at least one perforation which opens into the lower surface. The valve head of the valve body is disposed below the valve seat surface so as to resiliently contact the valve seat surface when no differential pressure acts on the valve. A stopper plate is disposed between the lower surface of the seat member and the valve head of the valve body. The stopper plate prevents the valve head from being excessively deformed into the perforation to cause cracks to develop in the valve head. As a result, the durability of the check valve device is improved.

摘要： A fuel injection control device for controlling a synchronous injection time period and an asynchronous injection time period. When the synchronous injection time period calculated from the operating state of the engine exceeds one time period of the synchronous injection, the actual synchronous injection time period is restricted so that it does not exceed one time period of the synchronous injection. When the request for the asynchronous injection occurs during the time the synchronous injection is carried out, the actual synchronous injection time period is prolonged by the asynchronous injection time period.

The apparatus includes a detection part for detecting a concentration of fuel in the fuel vapor purged into the intake passage so that a change in the detected fuel concentration from a time when a purge cutting is performed to a time when a purging is performed after the purge cutting has been performed is detected, and a discrimination part for determining whether there is a malfunction in the system on the basis of the change in the detected fuel concentration by the detection part. The apparatus also includes a fuel vapor detection part for detecting a condition of fuel vapor in the fuel tank, and a purge cut time varying part for varying a purge cut time period for which the purge cutting is continuously performed, the purge cut time being varied by the purge cut time varying part in response to the detected fuel vapor condition by the fuel vapor detection part.
