PROBLEM TO BE SOLVED: To solve a problem of burnt gas leakage and enable an engine to operate with as high heat efficiency as possible even if pre-ignition occurs due to the burnt gas leakage.SOLUTION: A hybrid vehicle engine controller comprises: a pre-ignition determination unit 100a determining whether pre-ignition occurs in an engine 10; a burnt-gas-leakage determination unit 100b determining whether the pre-ignition results from leakage of burnt gas to a next combustion cycle to a combustion cycle in which the burnt gas is generated; a burnt-gas-leakage inhibiting operation execution unit 100c executing a burnt-gas-leakage inhibiting operation (at a predetermined rotational speed for predetermined time in a state of correcting ignition timing to advance from predetermined timing) if it is determined that the pre-ignition results from the burnt gas leakage; and an ignition timing return unit 100d returning the ignition timing to the predetermined timing after executing the burnt-gas-leakage inhibiting operation. |
