摘要： An object of the present invention is to suppress the dispersion of EGR gas amount between cylinders when the stuck open state arises in an EGR valve in an EGR apparatus for an internal combustion engine in which an EGR passage is branched on an intake system side into a plurality of EGR branch pipes, and the respective EGR branch pipes are connected respectively to intake branch pipes provided for the respective cylinders. In the present invention, if the EGR valve is stuck open, the exhaust pressure is reduced in an exhaust system of the internal combustion engine, while suppressing an amount of decrease in a driving force of a vehicle which carries the internal combustion engine within an allowable range.

摘要： In a hybrid type vehicle designed to use an engine (1) and motor generators (MG1, MG2) to drive the vehicle, the engine (1) is provided with a variable compression ratio mechanism (A) and a variable valve timing mechanism (B). When a required output of the engine (1) is a boundary output (PY) or less, minimum fuel consumption rate maintenance control satisfying the required output of the engine by changing the engine speed in a state maintaining the mechanical compression ratio at the maximum compression ratio is performed. When the required output of the engine is increased over the boundary output (PY), the mechanical compression ratio is lowered to the minimum mechanical compression ratio, then the engine output is increased.

摘要： In a V-type six-cylinder engine, turbo-superchargers are provided for compressing intake air and feeding the compressed air into combustion chambers, and an ECU is operable to switch the combustion mode from a non-supercharged stoichiometric combustion mode to a supercharged lean combustion mode, depending on the engine operating conditions. When switching from the non-supercharged stoichiometric combustion mode to the supercharged lean combustion mode, the ECU retards the ignition timing, and keeps the retard amount of the ignition timing at a constant value if the increasing actual boost pressure becomes equal to or higher than a pre-set target boost pressure.

摘要： A control for an internal combustion engine in which it is determined whether a request for a turbo flow mode is output and whether there is a possibility that a catalyst may be deactivated. More specifically, it is determined whether a catalyst gas temperature is above a predetermined value. The predetermined value is set in advance so that when the catalyst gas temperature is equal to or below the predetermined value, the catalyst is deactivated. When it is determined that there is a possibility that the catalyst may be deactivated if exhaust valves are placed in the turbo flow mode, a retard amount in an ignition timing retard correction is determined. An ignition timing is calculated. It is permitted to switch a valve opening mode to the turbo flow mode.

摘要： An engine includes an in-cylinder injector injecting fuel into a cylinder, a port injector injecting fuel into an intake manifold, and a valve-opening-characteristic changing mechanism changing at least lift or opening duration of an intake valve. When the engine is in a predetermined operating region and the valve-opening-characteristic changing mechanism decreases the lift or the opening duration of the intake valve, the ratio of fuel injected by the in-cylinder injector is increased according to an amount of the decrease of the lift or the opening duration and accordingly a decrease in tumble ratio is compensated for by the injection flow.
