摘要： The present invention judges whether an internal combustion engine is operated by a special operation method in which a fuel cut is performed more frequently than predefined depending on the operation of an accelerator pedal. The present invention provides a shorter purge resumption period subsequently to recovery from a fuel cut when it is judged that the internal combustion engine is operated by the special operation method than when it is judged that the internal combustion engine is not operated by the special operation method. The purge resumption period is a period during which a purge gas flow rate is lower than during a steady operation.

摘要： A valve timing control device for an internal combustion engine comprises a variable valve timing mechanism capable of varying a valve overlap period. Fuel injection can be stopped in at least one predetermined engine operating condition and an optimal value of the valve overlap period in the current engine operating condition can be determined, on the basis of current engine speed, load, and temperature. The variable valve timing mechanism can be controlled such that the valve overlap period becomes larger than the optimal value when fuel injection is stopped. Accordingly, in the idle condition when the engine has not warmed up, intake air is heated sufficiently, by the valve overlap period, to more than the optimal value and an engine stall at this time is completely prevented by increasing the amount of intake air.

摘要： A valve timing control device for an internal combustion engine. The device comprises first determination means for determining a first optimal value of the valve overlap period in the current engine operating condition, on the basis of the current engine speed and load, second determination means for determining a second optimal value of the valve overlap period in the current engine operating condition by reducing the first optimal value when the engine has not warmed up, and valve overlap period control means for controlling a valve overlap period using the first optimal value when the current degree of opening of the throttle valve is larger than a predetermined value, even if the engine has not warmed up. A back-flow of exhaust gas does not occur when the degree of the throttle valve is relatively large so that the valve overlap period at this time is made larger and a higher engine torque can be obtained to increase the trapping efficiency and the scavenging efficiency, even if the engine has not warmed up.

摘要： A fuel injection timing control device for an internal combustion engine. The device comprises a fuel injector for injecting fuel into the intake port of an engine cylinder and an fuel injection end-timing control system for controlling the fuel injection end-timing of the fuel injector so as to advance gradually, from a first crank angle in the intake stroke to a second crank angle before the intake stroke, according to the engine operating condition. Accordingly, when the fuel injection timing is changed, the amount of fuel which sticks or adheres in the intake port is gradually increased by a small amount, at each fuel injection, so that the air-fuel ratio of the mixture does not become so lean the drivability of the vehicle is deteriorated.

摘要： An EGR apparatus includes an EGR conduit, an EGR valve, a first passage connecting a portion of an intake conduit downstream of a throttle valve and the EGR valve, and a second passage connecting a portion of the intake conduit upstream of the throttle valve and a medium portion of the first passage. A two-way solenoid valve is installed in the first passage between the intake conduit and a connecting portion where the first passage and the second passage join. Further, a fixed throttle is disposed in the second passage. By removing a VCV of a conventional EGR apparatus from the EGR apparatus and by replacing a three-way VSV of the conventional apparatus with a combination of the two-way solenoid valve and the fixed throttle, a problem of non-cutting of EGR, which can occur in the conventional apparatus, does not occur in the EGR apparatus of the invention.
