Abstract
An internal combustion engine control device which switches between a first operation of compression-igniting a premixed gas in a combustion chamber and a second operation of forcibly igniting the premixed gas through a spark plug in the combustion chamber. When switching between the first operation and the second operation, the control device inserts a transitional operation between the first operation and the second operation for the purpose of reducing torque variations in an internal combustion engine. In the transitional operation, the spark plug does not perform electric discharging, instead, the spark plug emits an electromagnetic wave to increase the temperature of the premixed gas, and subsequently, the premixed gas is compression-ignited.
Claims5
An internal combustion engine control device for controlling an internal combustion engine, wherein the internal combustion engine has a discharge unit for performing electric discharging in a combustion chamber and an electromagnetic wave radiation unit for radiating an electromagnetic wave to the combustion chamber, the internal combustion engine control device comprising:
- operation control units for switching between a first operation of compression-igniting a premixed gas in the combustion chamber and a second operation of forcibly igniting the premixed gas by electric discharging through the discharge unit in the combustion chamber according to an operation state of the internal combustion engine;
- wherein
- during the switching between the first operation and the second operation, the operation control units insert a transitional operation between the first operation and the second operation, and in the transitional operation, the discharge unit does not perform the electric discharging, instead, the electromagnetic wave radiation unit emits an electromagnetic wave to raise the temperature of the premixed gas, and consequently, the premixed gas is compression-ignited.
