Abstract

Swirl injector spray at high fuel temperature has features of rapid atomization and evaporation, compared to those at normal fuel temperature. These have a possibility to improve fuel consumption and emissions under cold start condition. The purpose of this study was to reveal the feasibility of improving cold start emissions of a DI engine by using high temperature fuel spray, to make a simulation procedure which can reproduce the spray formation process at high gasoline temperature and to incorporate it with a 3-D in-cylinder calculation of the mixture of in-cylinder gas and the spray. Results show that heating fuel was an affect to reduce the mass of wall-film. Thus using high temperature fuel has the possibility to improve fuel consumption and exhaust emissions under cold start condition.
