Description

Methanol-hydrogen fuel environment-protective motor

Affiliated technical field

The utility model relates to a kind of engine exhaust waste heat that utilizes methyl alcohol is decomposed, and makes engine for combusting methyl alcohol, and improves the methanol-hydrogen fuel environment-protective motor of power character.

Background technique

At present conventional engines is done part and improved back incendivity methanol fuel, the fuel of conventional engines comes out from fuel tank, enters combustion chambers burn under the effect of petrolift.Waste gas comes out to enter exhaust branch pipe from engine exhaust port, emits through flue gas leading again.Because heat absorption in a large number causes suction tude and oil nozzle temperature very low in the methanol gasifying process, causes methanol gasifying bad, the unclean and oil nozzle blocking phenomenon of methyl alcohol burning appears.In addition, the consumption of methanol fuel in service is also higher.

Summary of the invention

The utility model is the improvement of carrying out on the conventional gasoline engin structure, can be used as automotive fuel according to methanol liquid, a large amount of characteristics that absorb heat in the methanol liquid gasification, in the exhaust branch pipe shell of motor, economizer bank and reaction pipe are set, methanol fuel flows through from economizer bank and reaction pipe, utilize the waste gas residual heat of engine operation that methanol liquid is heated, make it abundant vaporization, help burning.

The technical scheme in the invention for solving the technical problem is:

Fuel tank is communicated with fuel feed pump, fuel feed pump is communicated with economizer bank, economizer bank is communicated with reaction pipe, reaction pipe is communicated with gas holder, and gas holder is communicated with gas mixer, and gas mixer is communicated with the firing chamber of motor by air intake branch, economizer bank and reaction pipe are arranged in the exhaust branch pipe shell, the import of exhaust branch pipe shell is communicated with exhaust opening of engine, and the outlet of exhaust branch pipe shell is communicated with flue gas leading, and the inlet/outlet of gas holder is provided with control valve respectively.Utilize engine exhaust heat to Methanol Decomposition, to reach engine for combusting methyl alcohol, sufficient combustion, the purpose of raising power.

The beneficial effects of the utility model are: can improve the gasification degree of methanol fuel, reach abundant burning, exhaust emissions is clean, because just to the improvement of exhaust branch pipe, simple in structure.
