摘要

The rail (1) has channels switchably connected with each other and arranged in the rail that is built in rotatable and slidable manner. One of the channels is provided to supply fuel i.e. liquefied petroleum gas, to a pump. Gas pressure is equal and high to fuel pressure, and gas is provided to the rail for injection point flowing. Fuel-injection time is adjusted by an instrument manufacturer. The liquefied petroleum gas is electrically heated with an air/water heat exchanger. The channels are connected to separately mix gas and fluid.
