Direct injection gasoline engines have been developed for the improvement of fuel economy and exhaust emissions. Recently, a new concept of stratified charge combustion has been proposed. A slit nozzle was adopted to realize the new concept. The nozzle has a rectangular orifice and forms a thin fan-shaped spray. This paper describes the spray characteristics of the slit nozzle. The following results were obtained. (1) The spray penetration increases with increasing the slit thickness. (2) The effect of the slit thickness on spray drop size is small. (3) The features of the slit nozzle are high spray penetration, widely diffuse spray and fine atomization compared with the swirl nozzle.
