Document Type and Number:
Japanese Patent JP3975695
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a self-ignition type engine capable of realizing a high temperature field required for activating a fuel with a minimum amount of air and reducing occurrence of fuel loss coming up with fuel activation. SOLUTION: A fuel-air mixture injection valve 8 for injecting the high temperature mixture obtained by mixing a high temperature air and a fuel directly into a combustion chamber 4 and a spark plug 9 disposed approaching the combustion chamber 4, are arranged adjacently to each other. During an intake stroke, the high temperature fuel-air mixture is injected by the injection valve 8, and during the injection period, a supplementary spark ignition is carried out by the spark plug 9, thus activating the fuel. At least one additional injection is performed during a compression stroke according to the load of the engine, and then a self-ignition is performed by the compression action of a piston 4.
