Abstract
The utility model relates to a feeding device for dimethyl ether compound fuel, which is composed of a dimethyl ether gas storing bottle, an evaporation pressure regulator, a mixer, a petroleum liquefied gas bottle, a computer, a diverter switch, a sensor, a stop valve and a pump. The dimethyl ether gas storing bottle is provided with an inflating port which is provided with an inflating valve; the outlet of the dimethyl ether gas storing bottle is communicated with the mixer through a pipeline; the petroleum liquefied gas bottle is communicated with the mixer and the pump through a pipeline; the pump inputs connects fuel passing through the mixer to the evaporation pressure regulator; the stop valve which is arranged on the evaporation pressure regulator is controlled by the computer and the diverter switch to supply fuel to a combustion chamber of an engine. High-pressure dimethyl ether and petroleum liquefied gas pass through the mixer from the dimethyl ether gas storing bottle and the petroleum liquefied gas bottle, and are sent to the evaporation pressure regulator; in the evaporation pressure regulator, the high-pressure dimethyl ether and the petroleum liquefied gas are evaporated into mixed compound fuel of low-pressure gaseous dimethyl ether and low-pressure gaseous petroleum liquefied gas; the mixed compound fuel enters the engine to burn. The evaporation pressure regulator evaporates the dimethyl ether and the petroleum liquefied gas into the low-pressure gaseous compound fuel to ensure the normal safe work of automobiles.
