Claims

[Scope of utility model registration request]

(1) A sensor group that detects the state of the engine, including a sensor that detects the ignition timing of the engine, a sensor that detects the idling state of the engine, a sensor that detects the engine rotation speed, and a sensor that detects the engine load. and a controller that controls the ignition timing of the engine based on the output of the sensor group. An engine control device characterized in that the ignition timing of the engine is retarded by a predetermined amount during high rotation and high load conditions.

(2) Utility model registration In the device according to claim (1), the sensor group includes a throttle sensor, and the controller controls the engine to be at high speed when the throttle is fully open based on the output of the throttle sensor. An engine control device characterized by determining that the engine is in a loaded state.

(3) Utility model registration In the device according to claim (2), the controller controls the amount of fuel injected into the engine, and when the throttle is not in a fully open state and the amount of fuel injected is equal to or more than a predetermined value, the controller controls the amount of fuel injected into the engine. An engine control device characterized in that the engine is determined to be in a high load state.
