摘要： A control device switches an engine between normal operation mode and special operation mode. In the normal operation mode, an independent cylinder configuration is formed to produce combustion independently in individual cylinders. In the special operation mode, a two-cylinder interconnect configuration is formed so that burned gas discharged from preceding cylinders currently in an exhaust stroke is introduced into following cylinders currently in an intake stroke through intercylinder gas channels, a lean mixture having a high air-fuel ratio is combusted in the preceding cylinders, and a mixture produced by supplying fuel to the burned gas is combusted in the following cylinders. When the engine is switched between the special operation mode and the normal operation mode, the control device selects transitional operation mode, in which the two-cylinder interconnect configuration is formed, and interrupts combustion in the preceding cylinders while producing combustion in the following cylinders by compression ignition.

摘要： A direct-injection spark-ignition engine includes a spark plug provided approximately at the center of the ceiling of a combustion chamber, and an injector having at its downstream end a nozzle which is located in an upper peripheral area of the combustion chamber, in which multiple openings are formed in the nozzle of the injector. Fuel is injected from the nozzle of the injector directly toward the proximity of an electrode of the spark plug. The directions of axis lines of the individual openings are set such that central points of fuel jets spewed out of the individual openings do not lie on the spark plug but are distributed around the electrode, slightly separated therefrom.

摘要： During stratified-charge combustion operation of a direct-injection spark ignition engine, at the cylinder compression stroke, a tumble is generated which flows between a spark plug electrode and a piston crown surface toward an injector. A fuel is injected from the injector in correspondence with the cylinder ignition timing by controlling the penetration of fuel spray from the injector to correspond to the tumble flow rate so that the fuel spray may go against the tumble, become a flammable mixture at the cylinder ignition timing and stay near the spark plug electrode. In the late stage of the compression stroke, diffusion of the flammable mixture is suppressed with squishes. Thus, fuel spray behavior in the combustion chamber is controlled to allow suitable mixture stratification over a wide engine operating condition range. This improves combustion quality and extends a stratified-charge combustion zone thereby providing enhanced fuel economy and power output.
