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： In an internal combustion engine, on a cylinder head side, a tumble flow is formed that is directed from an intake vent opened on the cylinder head to an exhaust vent opened on the cylinder head. A direct injection valve injects fuel directly into a combustion space. The direct injection valve injects the fuel toward a section where a piston top surface intersects with a cylinder inner surface, at a point closer to an intake top dead center than a middle between the intake top dead center and an intake bottom dead center, and thereafter injects the fuel into the combustion space again.

摘要： An internal combustion engine (10) is provided with a port injector (28) and an in-cylinder injector (22). Before a port injection is started, the total amount of fuel to be injected is calculated (at an injection amount calculation timing). The port injection fuel amount and the in-cylinder injection fuel amount are calculated by appropriately dividing the total amount between them. If a change of the operating load on the internal combustion engine (10) is detected after the injection amount calculation timing, the load change is reflected in the amount of fuel to be injected in the current engine cycle by increasing or decreasing the in-cylinder injection fuel amount.

摘要： An amount of NOx discharged from an internal combustion engine at the time of reducing the NOx stored in an NOx storage reduction catalyst is decreased. In an exhaust gas purification apparatus for an internal combustion engine which includes an NOx storage reduction catalyst arranged in an exhaust passage of the internal combustion engine for storing NOx in exhaust gas and reducing the NOx when an air fuel ratio of the exhaust gas is equal to or less than a stoichiometric air fuel ratio, an air fuel ratio control unit to change the air fuel ratio of the exhaust gas in the internal combustion engine, and an EGR device connecting between the exhaust passage and an intake passage of the internal combustion engine for supplying a part of the exhaust gas to the intake passage as an EGR gas, provision is made for an EGR ratio control unit that controls the EGR device in such a manner that in cases where the NOx stored in the NOx storage reduction catalyst is reduced by changing the air fuel ratio in the internal combustion engine, an EGR ratio becomes higher when the target air fuel ratio is low than when the target air fuel ratio is high.

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 and an EGR rate is controlled so as to be between 10% and 20%.
