Fuel system with electrically-controllable mechanical pressure regulator |
摘要 |
A method for operating an engine direct injection fuel system is provided. The direct injection fuel system includes a mechanical fuel pressure regulator that has a spring actuatable by an electric motor. The method includes adjusting a preload of the spring by operating the electric motor to adjust a set-point fuel pressure from a first set-point fuel pressure to a second set-point fuel pressure in response to an operating condition, and maintaining the preload of the spring mechanically when the electric motor is not operating. |
