Combustion Characteristics of the Torch Ignited Engine 741167

Experimental work of the torch ignited engine demonstrated that this engine provided stable engine performance and low exhaust emissions using an overall lean mixture.
Some combustion characteristics of the torch ignited engine were compared with those of a conventional one. Experimental analysis was performed to determine the influence of a number of prechamber inlet air-fuel ratios and nozzle diameters. These are respectively a main operating factor and a main design factor of the torch ignited engine. These factors control the torch combustion process and determine engine performance and emission characteristics.
