摘要： An engine ECU executes a program including: detecting a magnitude of vibration of an engine; detecting a vibration waveform of the engine based on the magnitude; calculating a correlation coefficient, in the case where the engine speed is smaller than a threshold value, using the sum of values each determined by subtracting a positive reference value from a magnitude of a knock waveform model, as an area of the knock waveform model and, calculating the correlation coefficient, in the case where the engine speed is not smaller than the threshold value, using the area of the whole knock waveform model; and determining whether or not knocking has occurred using the correlation coefficient. The correlation coefficient is calculated by dividing by the area the sum of differences that are each the difference between the magnitude on the vibration waveform and the magnitude on the knock waveform model.

摘要： A working angle (lift amount) of an intake valve is set to a predetermined first set value A1 during a period from when starting of the engine is initiated until when the engine is shifted to an initial combustion state, and the working angle is changed to a second set value A2 (=previous value (initial value is A1)+α) that is larger than the first set value A1 during a period from when the engine is shifted to the initial combustion state until when the engine is shifted to a perfect combustion state. When an engine rotational speed becomes equal to or higher than a reference rotational speed n1, it is determined that the engine has been shifted to the perfect combustion state, after which an engine starting routine ends.

摘要： An electronic control device is applied to an internal combustion engine including an engine driving pump, circulates lubricant by use of a driving force of the internal combustion engine, and reduces that driving load of the pump which works on the internal combustion engine, by executing a low-pressure control to limit a circulation amount of the lubricant when demand for the lubricant is small. Further, when a predetermined automatic stop condition is established, an engine operation is stopped automatically, and when a predetermined restart condition is established during the automatic stop, the internal combustion engine is restarted. Further, the execution of the low-pressure control is prohibited at the time of starting the internal combustion engine along with an operation of an ignition switch, but the execution of the low-pressure control is allowed at the time of restarting the internal combustion engine.

摘要： An engine adjusts the amount of intake air by cooperative control for the valve duration of the intake valve and the opening degree of the throttle valve. In the engine, the valve duration is fixed to a warm-up valve duration θw in a low-to-middle speed range of the engine during a period from immediately after starting of the engine to when warm-up is completed. In a high speed range, on the other hand, the valve duration is increased from the warm-up valve duration θw in accordance with increase in the engine speed Ne.
