Problems solved by technology

[0005] The above-mentioned prior art, under the cold start state, all need to use the waste heat of the engine of the hybrid electric vehicle to heat the alcohol cracking hydrogen generator first, let the alcohol cracking hydrogen generator reach the working temperature, the alcohol cracking hydrogen generator can produce hydrogen, like this There is actually a lag time in the production of hydrogen by the alcohol cracking hydrogen generator, and fuel oil is needed to start the engine during this period

Embodiment

[0054] Embodiment: Before the hydrogen-electric hybrid vehicle starts, first the electronic controller in the control circuit 66 instructs to turn on the cold start electric heater 24 power supply in the alcohol cracking hydrogen generator 1, for the vaporization overheating chamber 26 and the reaction chamber 16 Catalyst bed heats up quickly to provide heat. Under the condition that the storage battery pack on the hybrid electric vehicle has sufficient power of 30-50 kilowatts for standby, after the temperature reaches a predetermined value in three minutes, the automatic control instrument of the control circuit 66 commands the alcohol pump 47 to start, and the alcohol fuel is supplied by The alcohol fuel input pipe interface 21 enters the vaporization chamber 26 and heats up and vaporizes, passes through the wire mesh through the communication pipe 25, enters the reaction chamber 16, makes the alcohol vapor contact with the catalyst and passes through the catalyst bed for cat...

Abstract

The invention relates to a hydrogen hybrid electric vehicle, which adopts hydrogen as fuel and belongs to the field of automobiles. The hydrogen hybrid electric vehicle is characterized in that an alcohol pyrolysis hydrogen generator is serially connected onto an exhaust pipeline of a hydrogen engine, alcohol is catalyzed and pyrolyzed to generate hydrogen in the vehicle by the aid of exhaust waste heat (a supplementary heat source for realizing cold state temperature rise and keeping constant temperature of a reaction bed of the alcohol pyrolysis hydrogen generator adopts an electric heating mode), and generated hydrogen is transferred as the fuel of the engine so as to drive the vehicle to run and drive the engine to generate power and supply power for users. An ultra-low emission or zero emission level can be achieved when the hydrogen is combined with the engine to drive the vehicle. Alcohol can be made of various raw materials, including sugarcanes, corns, broomcorn, cassavas and the like which are reproducible resources and are inexhaustible. The alcohol as a raw material for generating the hydrogen can be water-contained methanol or ethanol of 50 degrees to 65 degrees, manufacturing process is simple, and cost is low. In addition, the liquid alcohol is also quite safe and convenient in storage, transport and network supply.

Description

Technical field: [0001] The invention relates to a method of heating an alcohol cracking hydrogen generator used for hydrogen production by engine waste heat to the working temperature required for hydrogen production by catalytic cracking in a cold start state, and allowing it to generate hydrogen; and then using the generated hydrogen as a hydrogen engine Fuel, the hydrogen-electric hybrid vehicle that drives the car, realizes that no or less fuel is used in the whole process, and the water-containing alcohol is directly cracked into hydrogen-rich gas fuel (3H2+CO2, CH4, CH3OCH3), and the hydrogen-rich gas is used as the hydrogen-electric hybrid Hydrogen-electric hybrid vehicles powered by automotive fuel. It belongs to the field of automobile engines. Background technique: [0002] Hydrogen is the ideal energy source pursued by mankind in the 21st century. The use of hydrogen as a vehicle fuel can completely get rid of human dependence on petroleum resources; it can fun...
