抄録: The effect of port water-injection on the exhaust NO_x reduction was examined experimentally as well as theoretically. In the experiment, water was injected into each suction port of a 4 cylinder turbocharged DI diesel engine using gasoline injectors. The exhaust NO_x was reduced significantly by port water-injection, and about 50% reduction in NO_x concentration was obtained by injecting an amount of 0.035kg of water/kg of air under various engine operation conditions. By comparing between the experiment and the analysis based on the authors' two-zone model, it is shown that the NO_x reduction is mainly caused by a decrease in the temperature of the burned gas resulting from an increase in the specific heat due to humidification.
