置。an operating state detection means for detecting the operating state of the engine; an intake state detection means for detecting an intake state other than intake air temperature;
an intake air temperature detection means for detecting the temperature of intake air, a knock detection correction means for detecting the occurrence of knock and changing the correction amount of the ignition timing in response to the presence or absence of knock, the above-mentioned operating state detection means and the intake air. When it is determined that the engine is in the knock limit state within a predetermined range from various detection signals from the state detection means and the intake temperature detection means, the intake air temperature is determined based on the detected value of the intake temperature and the actual ignition timing at that time. An engine intake air temperature detection device comprising an intake air amount calculation means for calculating an air temperature correction amount, and an intake air temperature correction means for correcting an intake air temperature detection value from the correction amount.
