Abstract:
An engine control method. A vehicle-mounted terminal can acquire a crankshaft signal of a vehicle in real time during the operation process of the vehicle; when the crankshaft signal indicates that a crankshaft of an engine is located at the bottom dead center of the crankshaft, the vehicle-mounted terminal can acquire the instantaneous rotation speed of the crankshaft, and determine a reverse rotation tendency of the crankshaft according to the instantaneous rotation speed; and when the reverse rotation tendency of the crankshaft meets a target condition, the vehicle-mounted terminal controls the engine to stop ignition and oil injection, so as to control the power output of the engine of the terminal, such that an impact on the crankshaft that is caused by the reverse rotation of the crankshaft is avoided, thereby prolonging the service life of the crankshaft.
