摘要： PROBLEM TO BE SOLVED: To enhance a fuel consumption by eliminating a pump loss through a laminar combustion under a partial load state, and increase the output through a premix combustion at the maximum output. SOLUTION: The device is provided with an ignition source 14 in the vicinity of a fuel injection valve 13, and ignites air-fuel mixture after fuel injection, diffuses generated flame in a cylinder by spray of fuel and executes laminar combustion in a partial load state. When the load is increased to produce soot or the like under the laminar combustion, fuel injection is performed several times. A premixture is formed in the cylinder through the first half injection. The premixture is burned in a short time by jetting a frame produced in the second half injection into a cylinder. By so doing, the device can reduce combustion time, prevent knocking, heighten a compression ratio of an engine, increase thermal efficiency and enhance fuel consumption. Production of unburnt hydrocarbon can be prevented by laminar intake. Responsiveness of fuel and operability are enhanced by the cylinder fuel injection. COPYRIGHT: (C)2007,JPO&INPIT
