INTERNAL COMBUSTION ENGINE DEVICE, HYBRID CAR, AND FUEL PROPERTY DETERMINATION METHOD

摘要

PPROBLEM TO BE SOLVED: To more properly determine the property of fuel to be supplied to an internal combustion engine. PSOLUTION: When a driver drives a vehicle by starting an engine, a counter C is incremented only by a value 1 when an integrated power Psum as the integrated value of a power consumption Pm1 of a motor is equal to or more than a threshold Pref (S260 to S300), and the counter C is compared with a threshold Cref (S310), and whether the property of fuel is heavy or light is determined according to whether or not the counter C becomes equal to or more than a threshold Cref (S320). Thus, it is possible to more properly determine the property of fuel in comparison with the case of determining the property of the fuel by comparing power consumption Pm1 of the motor with the threshold.
