Abstract
An engine fuel pump control apparatus is provided. The engine fuel pump control apparatus is connected to an engine and a transmission. A fuel pump is interposed in a fuel conduit between a fuel tank and the engine and the fuel pump has a selectively variable fuel delivery rate. A fuel pump controller is configured to adjust a fuel delivery rate from the fuel pump to the engine in which the fuel pump controller is configured to increase the fuel delivery rate as a rotational speed of the engine increases. The fuel pump controller is further configured to adjust the fuel delivery rate as a detected vehicle speed characteristic varies.
