Summary:

A fuel system design objective is to have the fuel injection pressure at target pressure by the time of the first injection. In most cases, a vapor and air space forms in the highest and hottest part of the fuel injector supply as the fuel system cools following engine-off. Upon key-on, the fuel pump needs to collapse the fuel vapor and compress any air before fuel pressure can build thus delaying fuel injector re-pressurization. An inventive solution to speed re-pressurization is described. It effectively eliminates the need to collapse the fuel vapor and compress any air in the first few tenths of seconds of fuel injection re-pressurization. The factors that affect fuel injection re-pressurization time are discussed
