Fuel pump controller/regulator for internal combustion engine feeds driver signal to fuel pump continuously depending on detected vehicle operating state compared with specified value

摘要

The fuel pump controller/regulator feeds a drive signal to an electrically actuated fuel pump intermittently to deliver fuel to an internal combustion engine in synchronization with an ignition signal for the engine. A driver signal is continuously fed to the fuel pump depending on a vehicle operating state detected by a detector and compared with a specified value.
