Abstract
An ignition timing control device (31) has a knocking detection device (41) that detects knocking of internal combustion engine (1) and an ignition timing adjustment device (43) that receives a knocking signal outputted from the knocking detection device (41) and a signal concerning the ignition timing of internal combustion engine (1) outputted from an external electronic control unit (37) and adjusts the ignition timing of internal combustion engine (1) according to the knocking signal and the signal concerning the ignition timing. Further, the knocking detection device (41) and the ignition timing adjustment device (43) are electrically connected and formed integrally with each other.
Claims21
An ignition timing control device comprising:
- a knocking detection device that detects knocking of an internal combustion engine;
- and
- an ignition timing adjustment device that adjusts an ignition timing of the internal combustion engine on the basis of a knocking signal indicating a knocking state which is obtained from the knocking detection device and a signal concerning the ignition timing of the internal combustion engine which is obtained from an external electronic control unit, and
- the knocking detection device and the ignition timing adjustment device being electrically connected and formed integrally with each other.
An ignition timing control system provided with an ignition timing control device and an external electronic control unit, wherein:
- the ignition timing control device has:
- an ignition timing adjustment device, and
- the external electronic control unit has:
- a judging unit that judges whether or not an operating condition of the internal combustion engine is in a timing in which the adjustment of the ignition timing is permitted;
- and
- a transmitting unit that, when the judgment as to whether or not the operating condition is in the timing in which the adjustment of the ignition timing is permitted is made by the judging unit, transmits a signal that includes information indicating whether the operating condition is in the timing in which the adjustment of the ignition timing is permitted to the ignition timing adjustment device.
