    摘要： A direct injection internal combustion engine of a compression ignition type in which portions of an injected fuel spray which have not been evaporated are prevented from striking the walls of the combustion chamber, and the fuel spray is prevented from catching up the air around it when moving in the combustion chamber, thereby providing an engine having reduced combustion noise, reduced amount of smoke and noxious emissions, and improved fuel economy. A combustion chamber is formed in the piston substantially in the form of a spherical cavity gradually narrowing towards the opening of the cavity at the top surface of the piston. An air intake mechanism swirls intake air supplied to the combustion chamber. A swirl injector injects a fuel spray substantially in the form of a hollow cone having a velocity component in a direction tangential of the central axis of the nozzle. The nozzle is offset from the central axis of the cavity and inclined with respect to the central axis of the cavity so that the fuel spray is injected in a forward direction of a swirl stream of intake air in the cavity.

    摘要： A direct injection type internal combustion engine has a piston reciprocatably fitted in the bore of a cylinder block defining a combustion chamber together with the cylinder block and a cylinder head. A main recess is formed in the combustion chamber for accelerating the swirl of intake air which is prepared and introduced by an intake device. At least one auxiliary recess is formed in the main recess and is arranged in the direction of the intake air swirl and in the direction of the fuel injection of a fuel injector for generating a secondary swirl different from the intake air swirl and for generating turbulence between the two swirls. Thus, the introduction of air into the fuel droplets fed from the fuel injector is promoted by the intake air swirl and the secondary swirl so that the combustion efficiency of the internal combustion engine is improved.

    摘要： There is provided a technique which can reduce the NOx stored in an NOx storage reduction catalyst. In case where concentrated reduction is carried out so as to add a reducing agent to the NOx storage reduction catalyst in a concentrated manner when a shift has been made from a state in which reduction of the NOx stored in said NOx storage reduction catalyst is unable to be performed in spite of a request for reduction of the NOx into a state in which reduction of the NOx is able to be performed, the level of concentration upon addition of the reducing agent is changed based on the amount of the NOx stored in the NOx storage reduction catalyst and the temperature of the NOx storage reduction catalyst.
