Abstract
An internal combustion engine includes: a combustion chamber to which a gas fuel containing hydrogen is supplied; an ignition device configured to ignite the gas fuel within the combustion chamber; and a control device for controlling execution of an ignition operation of the ignition device at a predetermined ignition timing. The predetermined ignition timing includes a first-time ignition timing of one combustion cycle, at which the ignition operation is executed for a first time, and a subsequent ignition timing of the one combustion cycle, at which the ignition operation is executed subsequent to the first-time ignition timing.
Claims7
An internal combustion engine, comprising:
- a combustion chamber to which a gas fuel containing hydrogen is supplied;
- an ignition device configured to ignite the gas fuel within the combustion chamber;
- a control device for controlling execution of an ignition operation of the ignition device at a predetermined ignition timing;
- and
- a misfire detection device for detecting a misfire within the combustion chamber in the one combustion cycle,
- wherein the predetermined ignition timing includes a first-time ignition timing of one combustion cycle, at which the ignition operation is executed for a first time, and a subsequent ignition timing of the one combustion cycle, at which the ignition operation is executed subsequent to the first-time ignition timing,
- wherein the control device is configured to:
- execute the ignition operation of the ignition device at the subsequent ignition timing, when the misfire detection device detects the misfire within the combustion chamber;
- and
- stop the ignition operation of the ignition device at the subsequent ignition timing, when the misfire detection device does not detect the misfire within the combustion chamber, and
- wherein the misfire detection device is configured to determine that the misfire has occurred, if a maximum pressure within the combustion chamber after the first-time ignition timing and before the subsequent ignition timing of the one combustion cycle is not greater than a predetermined pressure.
