    An optically accessible Dl diesel engine has been constructed to study combustion, emission, spray, and flow field phenomena. The goal of the present investigation is to study the effect that intake charge temperature variation at constant density has on combustion, emissions, and spray vaporization in both quiescent and swirling environments. The results indicate that raising intake temperatures decreased the ignition delay, peak rate of premixed burning, and premixed fraction. Increasing intake temperature increased the peak rate of diffusion burning in the quiescent environment, but mixing effects balanced temperature effects in the swirl environment and peak diffusion burning remained constant. Inmore » general, NO{sub x} increased with increasing temperature and amount of diffusion burning, but lower temperature data suggests that premixed and diffusion burning are both contributing to NO production. Combustion photography shows that first visible light occurs very close to start of combustion and typically before peak premixed burning which indicates the visible light is emitted in the premixed stage of combustion. Under nonfiring conditions, shadowgraph photography indicates that increasing intake temperature had little effect on fuel plume penetration to the walls, however, swirl has a dramatic effect on tangential fuel distribution.« less

    Characteristics of diesel combustion with high pressure fuel injection were investigated, using a supercharged and charge air cooled single cylinder engine. Observation and analysis of combustion was performed using high speed schlieren photography at a definite low level NOx emission, while varying the parameters of both injection pressure and swirl ratio. Engine performance at a high injection pressure was evaluated in combination with shallow dish type combustion chamber and 8 hole nozzle. Two different intake ports (higher and lower swirl ratio) were used for the evaluation. Conventional injection system in combination with toroidal cavity and 4 hole nozzle was comparedmore » as a base line. It is generally said that quiescent combustion system is suitable for higher injection pressure configuration. According to the observed result of combustion photographs, however, higher swirl ratio shows better mixing than a lower swirl ratio, which was also confirmed by the performance test.« less
