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： An internal combustion engine includes an in-cylinder injection valve and an intake passage injection valve. A control apparatus of the engine determines whether a catalyst located in an exhaust passage is in an overtemperature condition. When the catalyst is determined to be in the overtemperature condition, the control apparatus controls the injection valves to increase the amount fuel supplied to the cylinder compared to a case where the catalyst is determined not to be in the overtemperature condition. The control apparatus sets a mode for causing the injection valves to increase the amount of supplied fuel according to an operational state of the engine. For example, in a case where the component is determined to be in the overtemperature condition when the engine is operating in a fuel injection mode in which fuel is injected at least from the in-cylinder injection valve, at least the intake passage injection valve performs fuel injection for increasing the supplied fuel. Therefore, the catalyst is reliably prevented from being overheated.

摘要： An internal combustion engine includes an in-cylinder injection valve and an intake passage injection valve. A control apparatus of the engine determines whether the temperature of a component located in the exhaust passage is higher than or equal to a predetermined temperature. When the temperature of the component is higher than or equal to the predetermined temperature, the control apparatus increases, without changing the total amount of fuel supplied to the cylinder, the ratio of a fuel injection amount of the intake passage injection valve to a fuel injection amount of the in-cylinder injection valve compared to a case where the temperature of the component is not higher than or equal to the predetermined temperature. Therefore, the catalyst is reliably prevented from being overheated, while preventing the fuel economy from deteriorating.
