Abstract:
An apparatus for priming a diesel fuel system, said diesel fuel system comprising a diesel engine having a plurality of injectors, said injectors receiving a supply of diesel fuel from a fuel injection pump, said supply of diesel fuel stored in a fuel tank coupled to said fuel injection pump through a fuel line, said apparatus for priming comprising:a fuel feed pump coupled in said fuel line between said fuel tank and said fuel injection pump, said fuel feed pump supplying said diesel fuel to said fuel injection pump; anda controller coupled to said electric fuel feed pump, said controller having control logic operative to calibrate a length of an initial operating time period such that said fuel feed pump obtains a desired pressure, energize said fuel feed pump during said initial operating time period, calibrate a length of a second operating time period such that heat is minimized, de-energize said fuel pump during said second operating time period, energize said fuel feed pump during a priming time period, whereby said diesel fuel system is primed with diesel fuel, and de-energize said fuel pump after said priming time period.
