We have studied the fuel behavior in Port-injection gasoline engines as the following: Different from the existing indirect analysis, this method enables direct measurement of fuel behavior even during the actual firing operation. This allows the separation of the amount of fuel behavior between the intake port and the cylinder to occur, thus making it clear that the amount of wall-wetting fuel not only in the port but also in the cylinder should be taken into consideration when evaluating the fuel transfer delay in the transient performance. By using this method, we were able to gain a complete picture of the fuel behavior, which has always been rather ambiguously defined.
