汽车电喷燃油泵
汽车电喷燃油泵 燃油泵向分油管输送高压燃油，保证向喷油嘴供应持续的燃油。 燃油泵在启动和发动机运转时工作，如果发动机停止而点火开关仍处于ON 时，HFM-SFI 控制模块关闭燃油泵的电源，以避免意外点火。燃油泵位于车辆油箱内部。

An electric fuel pump is a tool used to power a vehicle's engine system by providing fuel through the use of electronic means. The electric pump is a post-World-War-II innovation that made cars more efficient, reliable and affordable. The electric fuel pump is an alternative to a manual fuel pump system and is widely considered to be a better use of technology with regards to the function and operation of motor vehicles.
An electric fuel pump is small and thermally insulated to prevent sparking. Generally, it consists of a 12-volt electric motor attached
to a
pump assembly that pulls fuel in as the motor spins, and pushes it out through a different line that goes to the engine compartment. The fuel may pass through a fuel filter after it leaves the pump, or it may be filtered before the pump. The assembly runs at a constant pressure to allow for optimum fuel delivery to the engine without interruption and also to prevent air from getting into the fuel lines and causing problems.
Old-style fuel pumps were manual pumps that ran because the engine ’s rotation caused a small arm to lift and pull fuel into a float bowl. After the fuel entered the float bowl, it could be sucked by vacuum into the carburetor to be delivered to the engine. This system was effective, but could cause problems.
