Title:
COMPRESSION SELF-IGNITION TYPE INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP3965905
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To avoid the occurrence of knocking by suppressing abrupt combustion and enlarge an ignition timing allowable range during compression self-ignition combustion operation.
SOLUTION: This compression self-ignition type internal combustion engine, wherein a mixture in a combustion chamber is self-ignited and burnt by the compressing operation of a piston, comprises lowering a temperature in the combustion chamber during heat generation after combustion self-ignition. When a self-ignition timing is earlier than a target self-ignition timing or a pressure rising rate after self-ignition is larger than a target pressure rising rate, a fuel or a water is injected from a fuel injection valve 19 into the combustion chamber 9 to lower a temperature in the combustion chamber 9.
