Abstract

A heated methanol-hydrogen fuel engine methanol-hydrogen fuel engine is mainly an improvement of a fuel supply system and gas feeding and discharging branch pipes of the traditional engine. The fuel of the heated methanol-hydrogen fuel engine is the methanol. The output of the methanol fuel tank of the engine has two fuel supply systems; one system changes the methanol into the atomized methanol so that the methanol can enter a combustion chamber through a branch pipe, while the other system heats and vaporizes the methanol and then uses the catalyst to crack the hydrogen and carbon monoxide into the combustion chamber through a branch pipe. Because of the high calorific value and the good diffusibility of the hydrogen, the engine drive is increased. In order to overcome the decalescence phenomenon of the methanol atomization, the gas feeding branch pipe passes through the gas discharging and heating device; the surplus heat of the engine is used for overcoming the wax formation on the oil nozzle, the difficult atomization and the impure combustion.

Description

Heating methanol-hydrogen-fuel engine

It is the structure that the basis produces methyl alcohol evaporative gas and two kinds of combustion gas of hydrogen with the liquid methanol fuel that the utility model relates to a kind of, heating methanol-hydrogen-fuel engine.

At present, known automobile all is to use gasoline or diesel oil, and combustion gasoline or diesel-oil vehicle environmental pollution are serious, and petroleum resources are exhausted day by day.Though the improved methanol vehicle of tradition has improved pollution to environment, must mix burning to methyl alcohol and gasoline with certain proportion, this is low because of the calorific value of methyl alcohol, burn insufficient and take remedy way.The methyl alcohol of certainty ratio and gasoline are mixed to burn and are returned the driver operation and make troubles, because the proportion of methyl alcohol and gasoline is different, the vehicle lay-off time is long slightly, methyl alcohol and gasoline even stratification can occur.

Consult shown in Figure 1ly, conventional engines fuel system structure and working principle: fuel comes out to enter atomizer 15 through defeated fuel pipe 2 under petrolift 20 effect from fuel tank 1, enters firing chamber 19 again and burns, and produces power.

The purpose of this utility model provides a kind of heating methanol-hydrogen-fuel engine, on-stream of motor is with a kind of fuel of methyl alcohol, but, can carry methyl alcohol evaporative gas and two kinds of combustion gas of hydrogen by two kinds for fuel structures, it can overcome, and the methyl alcohol calorific value is low, diffusivity difference and the unclean defective of burning.

The purpose of this utility model is achieved in that at the methanol fuel case two outlets is set, adopt two kinds of different fuel systems respectively, a system is methanol fuel case and the logical knot of atomizer with connecting pipe, atomizer by suction tude and firing chamber together with, this is a methyl alcohol evaporative gas fuel system; Another system is provided with the hydrogen from methyl alcohol reactor at the outlet pipe outer surface, in the hydrogen from methyl alcohol reactor, catalyzer is set, with connecting pipe methanol fuel case and hydrogen from methyl alcohol reactor are linked, with hydrogen feeding pipe the hydrogen from methyl alcohol reactor is communicated with atomizer again, atomizer is communicated with the firing chamber by suction tude, form methanol vaporization and be decomposed into hydrogen and CO burning system, two kinds of gases enter firing chamber mixed combustion.

For overcoming methyl alcohol atomizing heat absorption phenomenon, air intake branch of the engine is passed among the heating equipment that outlet pipe is provided with, make air discharge heating apparatus surround air intake branch.

Because the methyl alcohol mixed gas is heated and decomposes the hydrogen calorific value height that produces, and diffusivity is good, so that the mixture combustion in the firing chamber is thorough, the engine power raising.

Owing to adopt such scheme, solved the low and clean problem of burning of methyl alcohol combustion heat value, improve the power character of motor, and had advantages such as driver is easy to operate.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is the fuel system structural representation of conventional engines.

Fig. 2 is heating methanol-hydrogen-fuel engine embodiment's a structural representation.Among the figure 1, methanol fuel case, 2. defeated fuel pipe, 3. defeated fuel pipe, 4. air-strainer, 5. hydrogen feeding pipe, 6. exhaust branch pipe, 7. silencing apparatus, 8. cylinder, 9. piston, 10. hydrogen from methyl alcohol reactor, 11. catalyzer, 12. methyl alcohol nozzles, 13. fuel mixture imports, 14. outlet ports, 15. atomizers, 16. hydrogen from methyl alcohol Reactor inlet, the outlet of 17. hydrogen from methyl alcohol reactor hydrogen, 18. air intake ducts, 19. engine chambers, 20. petrolifts, 21. petrolifts, 22. air discharge heating apparatus, 23. air intake branches.

In Fig. 2, methanol fuel case (1) is communicated with defeated fuel pipe (2), and defeated fuel pipe (2) is communicated with atomizer (15), and atomizer (15) is communicated with engine chamber (19) by air intake branch (23), and this is a methyl alcohol evaporative gas fuel system; Methanol fuel case (1) is communicated with defeated fuel pipe (3), defeated fuel pipe (3) is communicated with the import (16) of hydrogen from methyl alcohol reactor (11), hydrogen from methyl alcohol reactor (11) is arranged on the outer surface of outlet pipe (6), catalyzer (11) is set in the reactor (10), the hydrogen outlet (17) of hydrogen from methyl alcohol reactor (10) is communicated with hydrogen feeding pipe (5), hydrogen feeding pipe (5) is communicated with atomizer (15), atomizer (15) is communicated with engine chamber (19) by air intake branch (23), and this is the hydrogen from methyl alcohol fuel system; Exhaust branch pipe (6) is provided with heating equipment (22), heating equipment (22) surrounds air intake branch (23), air intake branch (23) passes among heating equipment (22), because methyl alcohol evaporative gas and hydrogen mix and is heated (19) internal combustion in the firing chamber afterwards, engine power improves.
