    摘要： An exhaust emission control apparatus for an internal combustion engine includes a fuel injection valve placed substantially at a midpoint above a combustion chamber of the engine; a piston having an outer cavity formed substantially in a midsection of an upper surface of the piston and an inner cavity formed in a bottom surface of the outer cavity; an ignition plug placed in a region right above the outer cavity; an exhaust purifying catalyst provided in an exhaust passage of the engine; and a controller. This controller is configured to carry out a stratified charge combustion when a temperature rise for the exhaust purifying catalyst is required, by forming air-fuel mixture which is richer than stoichiometric ratio and is able to be ignited by the ignition plug, within the outer cavity and in an area substantially right above the outer cavity, from a fuel injected through the fuel injection valve.

    摘要： A direct fuel injection internal combustion engine includes a fuel injector arranged above a center portion of the piston and positioned higher than a combustion chamber upper surface of a cylinder head. The cylinder head includes a recess portion in which a tip of the fuel injector is disposed in a cross sectional view of the cylinder head in a plane perpendicular to a fuel injection center axis. The recess portion is provided with a channel extending longitudinally away from the tip of the fuel injector configured and arranged to reduce negative pressure within the recess portion. The channel is oriented in such a direction as to avoid the interference between the channel and other parts of the cylinder head. When the fuel injector is a multi-hole fuel injector, the channel can be oriented toward a direction along a centerline between two adjacent injection vents of the fuel injector.

    摘要： A control apparatus is provided for a four stroke cylinder direct-injection internal combustion engine having a cylinder and a piston disposed within the cylinder. The control apparatus includes a variable compression ratio mechanism for variably controlling the engine compression ratio by changing the top dead center position of the piston and a fuel injection device for injecting fuel directly into the cylinder. When the actual compression ratio of the engine is higher than a target compression ratio, the variable compression ratio mechanism reduces the compression ratio, and in accordance with the reduction in the compression ratio, the fuel injecting device injects an intake fuel injection amount in the intake stroke and a compression fuel injection amount in the compression stroke, and the timing for starting the fuel injection in the compression stroke is retarded.
