Abstract
A direct injection fuel supply system, in one exemplary implementation, includes a lift fuel pump, a positive displacement pump, at least one fuel injector and an accumulator assembly. The lift pump is adapted to be in fluid communication with a supply of fuel and the positive displacement pump is in fluid communication with and downstream of the lift pump. The at least one injector is in fluid communication with an outlet of the positive displacement pump via a high pressure fuel line. The accumulator assembly includes an accumulator and a valve, where the valve is in direct fluid communication with the high pressure fuel line and the injector. The valve is selectively controlled to at least one of an open state providing fluid communication between the accumulator and the high pressure fuel line and a closed state blocking fluid communication between the accumulator and the high pressure fuel line.
