When, pass through evaporation tube described in the heating devices heat.
There is no tail gas discharge in engine start, in the exhaust pipe of engine, vehicle power supply is powered to heating device, by adding
Thermal heating evaporation pipe, provides net quantity of heat needed for fuel evaporation；After Tail Pipe Temperature reaches set temperature, vehicle power supply
Stop being that heating device is powered, net quantity of heat needed for providing fuel evaporation as tail gas, in the process, evaporation tube completes liquid
The evaporation of fuel oil and the preheating of fuel-steam make fuel oil participate in combustion reaction in the form of high temp oil-fired steam.
In above scheme, further, to guarantee that heat transfer is uniformly between evaporation tube and evaporator support frame, in evaporator branch
It is marked with heat transfer medium inside the spiral guide slot of support, specifically, heat transfer medium can be quartz sand.
In above scheme, specifically, heating device is PTC heat block；PTC heat block is mounted on steaming by heat block pedestal
It sends out on device support frame.
In above scheme, further, caused to prevent the substances such as the water in vehicle driving on road surface from contacting vaporising device
Thermal loss influences the job stability of heater, thermal insulation layer is also wrapped on the outside of heating device.
The utility model has the advantages that
(1) present invention using tail gas heat quantity come evaporated liquid fuel oil, steam by the evaporation and fuel oil for being completed at the same time liquid fuel
The preheating of vapour reduces the waste of energy of engine's tail gas, improves the thermal efficiency of engine；Liquid fuel flashes to fuel oil steaming
Injection engine acting chamber after vapour, fuel oil participate in burning in intracavitary mix with air of doing work in the form of high temp oil-fired steam, mention
The high burning adequacy of fuel oil, improves capacity usage ratio, while reducing the probability of engine carbon-deposits the cylinder, extends hair
The service life of motivation.
(2) the configuration of the present invention is simple, occupied space is smaller, can complete all kinds by replacing the evaporation tube of unlike material
The evaporation warm operation of liquid fuel.
