摘要： The invention relates to a cylinder direct injection engine in which fuel is injected directly into combustion chambers and air-fuel mixture is guided by an air flow. In such engines it is difficult to secure combustion stability under low engine speed and low load conditions such as during idling. Furthermore, there are needs for improvement of emission characteristics and fuel economy in other operation modes as well. An engine according to the invention injects fuel while dividing the same in plural parts during a compression stroke. A fuel injection valve (1) comprises a radial fuel passage (221) located upstream of a valve seat (210), which radial fuel passage (221) leads radially from outside to inside to impart a swirling force to fuel.

摘要： The invention relates to a gasoline engine is provided which is capable of introducing a large amount of EGR gas for performing homogeneous combustion and thus offering a good fuel economy. An external EGR mechanism or an internal EGR mechanism is used to introduce an EGR gas into a combustion chamber (a cylinder) (11). A mixture of fresh air and fuel is thereafter directly injected from a mixture injection valve (13) into the combustion chamber (11), thereby forming a region (12) of said mixture in an area near an ignition plug (21, 22). In addition, engine operating parameters are controlled in accordance with the amount of fresh air supplied into the combustion chamber (cylinder) (11) after an intake valve (7b) has been closed. This makes possible homogeneous combustion using a large amount of EGR, which eventually increases fuel economy.

摘要： Under a partial load, a pumping loss is reduced by a stratified combustion to enhance a fuel consumption, and during the maximum output operation, the output is increased by a premixture combustion, and the output of an engine is controlled, thereby enhancing the drivability. Under the partial load, an ignition source is provided in the vicinity of a fuel injection valve, and after the fuel is injected, the mixture is ignited, and a resulting flame is caused by a spray of the fuel to spread into a cylinder, thereby effecting a stratified combustion. When the load increases, so that soot and so on are produced in the stratified combustion, the fuel injection is effected a plurality of times in a divided manner, and a premixture is produced within the cylinder by the front-half injection, and a flame, produced by the latter-half injection, is injected into the cylinder to burn this premixture.
