System och förfarande för att undvika förlust av flöde i en dieselmotors bränslesystem

摘要

A system and method for avoiding loss of prime in a primed fuel system of a diesel engine ( 10 ) that propels a motor vehicle. With the engine running, a control system ( 14 ) shuts down the engine when a fuel level sender ( 20 ) indicates an incipient risk of the fuel system losing its prime due to insufficient fuel in the tank ( 16 ). In one embodiment, the engine cannot be re-started until more fuel is added to the tank. Another feature allows engine re-starting and limited running after a shut-down by first turning the ignition switch ( 48 ) to OFF.
