(57) Abstract :
A starting system is provided for delivering pressurized fuel to an engine to start the engine without a starter. The starting system
includes an accumulator for storing pressurized fuel during engine operation and engine shut-down. During engine start-up, the
accumulator delivers the stored pressurized fuel to the engine to start the engine. The accumulator is in fluid communication with a
low pressure fuel reservoir and the engine. The accumulator includes an accumulator housing defining an accumulator cavity and
including an accumulator piston and spring assembly, which is moveable longitudinally within the accumulator cavity. An electronic
control module (ECM) is in electronic control with the starting system and the engine. The ECM is operable to activate the
accumulator, forcing pressurized fuel stored within the accumulator into a high-pressure fuel line for injection into the engine, to
generate at least one starting combustion event to start the engine without a starter.
