Start-up operation method of premixed compression ignition engine and premixed compression ignition engine

摘要

PPROBLEM TO BE SOLVED: To realize technology of starting operation for keeping stable operating condition without remarkable lowering of equivalence ratio of mixture in a combustion chamber in transition to the premixed compression ignition operation after spark ignition operation of spark igniting the mixture in the combustion chamber in the starting operation of the premixed compression ignition engine adapted to perform self-ignition by compressing the mixture in the combustion chamber. PSOLUTION: After spark ignition operation is performed, the transition to increase exhaust gas recirculation quantity is performed to start the premixed compression ignition operation.
