Abstract

The invention discloses a methanol fuel carburetor vehicle, a heater for heating methanol fuel to promote the atomization of methanol and an auxiliary heating mode of the heater. The defects that the methanol can not be well atomized, can not form a uniform combustible mixed gas together with air and further can not be combusted because the methanol fuel is used directly on a carburetor vehicle are overcome. A methanol fuel vehicle heater is additionally arranged between a carburetor (or a carburetor base) and an air intake manifold, the heater is a hollow water jacket, the upper part of the heater is connected with the carburetor or the carburetor base, and the lower part of the heater is connected with the air intake manifold. Methanol and air mixed gas passes through the hollow part of the heater, engine circulating hot water passes through the inside of the water jacket at the circumference of the outer wall of the hollow part, and heat of the circulating hot water in the water jacket is transferred to the methanol and air mixed gas in the hollow part. Meanwhile, by means of the heat of a tail gas exhaust pipe, the heat is transferred to the air intake manifold in a heat conduction way and is used as an auxiliary source of heat absorbed by the methanol fuel. The aim of heating is to meet the requirement of the methanol for latent heat of vaporization and better atomize the methanol, so that vehicles realizing carburetor oil supply can direct use the methanol fuel as a power source.

Description

Methanol fuel car heater

Affiliated technical field

The present invention relates to a kind of Carburetor vehicle that uses methanol fuel, methanol fuel is heated the heating equipment that impels the methyl alcohol atomizing.

Background technique

At present, the gasoline car of known Carburetor form all can not directly use methyl alcohol to act as a fuel.Only if change Carburetor fuel feeding form into automatically controlled EFI fuel feeding form, and then install a cover auxiliary computer plate (auxiliary ECU) additional, could use methanol fuel.But now so much Carburetor car is arranged again on the market, and this methanol fuel car heater, the vehicle to this Carburetor form can directly use methanol fuel exploitation just.It has reduced Carburetor and has changed the lack of standardization of automatically controlled EFI and change the car operation and change the car cost.

Summary of the invention

The gasoline car of existing Carburetor form if directly use methanol fuel, will exist the methyl alcohol atomizing bad, can not form the inflammable mixture that mixes with air, so that can not burn.In order to overcome the deficiency that existing Carburetor car can not directly use methanol fuel, simultaneously to change the lack of standardization of automatically controlled EFI car and change the car operation and change the car cost in order to stop the Carburetor car.The present invention provides a kind of methanol fuel car heater, and this heater not only safety is small and exquisite, and can let the Carburetor car directly use methanol fuel.

The technical solution adopted for the present invention to solve the technical problems is: methyl alcohol is before getting into engine cylinder combustion; Need good atomizing just can better with air mixing; Form burning mixture (mixed gas of optimal air-fuel ratio), could in cylinder, reach good burning.But according to the characteristic of methyl alcohol, the latent heat of vaporization of methyl alcohol is very big, and atomizing needs to absorb great amount of heat.Therefore for the foregoing reasons, this heater is exactly to utilize the hot water circuit of motor to come methyl alcohol and Air mixing gas are heated, and needs heat with the atomizing of satisfying methyl alcohol, makes the methanol fuel back that fully atomizes form inflammable mixture with air, the entering cylinder combustion.Methanol fuel car heater is installed between Carburetor (or carburettor base) and the intake manifold.Heater is the water jacket of a hollow, on connect Carburetor or carburettor base, connect down intake manifold.The heater hollow space is crossed the methanol fuel air Mixture, crosses engine cycles hot water in the water jacket around the hollow space outer wall.Let the heat of circulating hot water in the water jacket pass to the methyl alcohol air Mixture of hollow space through transmission of heat.When installing heater additional,, heat is conducted to the air inlet manifold, absorb a kind of auxiliary source of heat as methanol fuel through heat conducting mode by the heat of exhaust pipe.

The invention has the beneficial effects as follows, can make methyl alcohol well atomizing the time, can reduce engine water temperature easily again, not only fuel saving but also motor is worked more stably.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Embodiment

In Fig. 1; Methanol fuel sprays through carburetor jet (1); With air mixing, get into mixed gas intake duct (9), methanol fuel is through absorbing the heat of carburettor base (4) inwall and heater (5) inwall; Methanol fuel is fully atomized and form inflammable mixture to get into intake manifold (7), get into each cylinder of motor (8) burning at last with air.For the conduction of strengthening heat between heater (5) and intake manifold (7), be connected with copper sheet (10) between heater (5) and the carburettor base (4).

In Fig. 2; Engine cycles hot water heater via intake pipe (6) gets into heater (5); Hot water in the heater (5) is followed the methanol fuel in the mixed gas intake duct (9) through carburettor base (4) inwall, heater (5) inwall and intake manifold (7) with heat transfer, and circulating water flows back to motor from the heater outlet pipe at last.

In Fig. 3, through connecting bolt through hole (11) intake manifold (7), heater (5) and carburettor base (4) are firmly connected with long connecting bolt.
