Control device of combustion in internal-combustion engine

Abstract

Abstract PURPOSE:To sufficiently suppress the generation of NOx, by calculating the combustion temperature on the basis of light emitted at an explosion stroke in a cylinder and feedback controlling the combustion of an engine in accordance with said combustion temperature. CONSTITUTION:Light emitted from the inside of a cylinder in an engine 1 is detected by a light detecting means 11 and converted into a signal of combustion temperature by a light-temperature converting means 13. A combustion control arithmetic means outputs a control signal of combustion on the basis of the output of a crank angle detecting means 27. A combustion control means 32 controls the combustion temperature of the engine 1 on the basis of the control signal of combustion. In such way, the generation of NOx is suppressed, while drivability of the engine and its fuel comsumption can be improved.
