摘要： An exhaust circulation apparatus that can improve fuel combustion and suppress discharged NOx by expanding an operating region in which homogeneous lean combustion is possible. The exhaust circulation apparatus includes a homogeneous lean combustion unit for performing homogeneous lean combustion in a predetermined lean-burn region, and an EGR apparatus for performing EGR that recirculates a portion of gas that flows through an exhaust system of the internal combustion engine to an intake system. When performing homogeneous lean combustion, the exhaust circulation apparatus controls the EGR apparatus to perform EGR. An LPL-EGR apparatus that recirculates gas flowing through an exhaust passage on a downstream side of a turbine to an intake passage on an upstream side of a compressor is used as the EGR apparatus. Preferably, an air-fuel ratio is controlled so as to be 22:1 and an EGR rate is controlled so as to be between 10% and 20%.

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.

摘要： An intake control device for an internal combustion engine having a first intake passage (5); a second intake passage (8); an intake passage length-changing valve (11); a partition (14) that partitions the intake passage into two partitioned intake passages (12, 13); and a tumble control valve (17). When one of the partitioned intake passages (12) is closed by the tumble control valve (17), air drawn into a combustion chamber through the open partitioned intake passage (13) forms a tumble flow. The length of the second intake passage (8) is longer than the length of the first intake passage (5) from a surge tank (1) to the connection point (S) between the second intake passage (8) and the first intake passage (5), and the passage cross-sectional area of the second intake passage (8) is smaller than the passage cross-sectional area of the first intake passage (5) from the surge tank to the connection point (S).
