When the starter works, a certain time is needed for starting a vehicle by the starter in the prior art, inconvenience is brought to a user, a large amount of electric quantity needs to be consumed when the vehicle is powered to cause the starter to generate heat, and the efficiency of an automobile battery is reduced in low-temperature weather, so that the automobile battery is easy to lack of power, further the ignition failure of the automobile is caused, and the starting of the automobile is influenced; the first electromagnetic valve 1 is arranged in an air inlet pipe of an automobile, so that a channel of the first electromagnetic valve 1 is superposed with a channel of the air inlet pipe, the second electromagnetic valve 3 extends into an inner cavity of the air inlet pipe, and an automobile battery is electrically connected with the automobile air inlet pipe; when the automobile is started, the storage battery of the automobile energizes the electromagnetic valve, so that the heating net 4 generates heat, and meanwhile, the channel of the first electromagnetic valve 1 is closed, so that the air inlet pipe of the automobile cannot enter air; then the second electromagnetic valve 3 is opened under the control of the controller, so that the inflammable gas in the gas storage box 2 is sprayed out under the action of pressure to enter an air inlet pipe of the automobile, and the inflammable gas is heated by the heating net 4 after contacting the heating net 4, so that the inflammable gas is rapidly combusted; the combustible gas is combusted to generate a large amount of heat, so that the air in the automobile air inlet pipe is heated, the air in the air inlet pipe meets the starting condition of the engine, and the engine sucks hot air after the air is heated, so that the starting is finished; after the engine is started, the first electromagnetic valve 1 is intermittently opened and closed, so that air can enter the engine, the problem that the air inlet of the engine is not smooth is avoided, and the engine stops working after the engine is completely started; the air required by the starting of the engine is kept in the closed space for heating, so that the temperature of the air sucked by the engine is in a normal range, the engine can be quickly started, the starting time is saved, meanwhile, only the heating net 4 needs to be heated for a short time in the process of igniting the combustible gas, a storage battery does not need to continuously provide large current for heating, the consumption of the electric quantity of the storage battery is reduced, the normal starting of the engine is ensured, the automobile can still be normally started in long-term low-temperature weather or under the condition that the automobile is not started for a long time, the combustible gas enables the heating net 4 to be continuously heated to have residual temperature after being combusted, and the consumption of the electric quantity is also reduced; the combustible gas can adopt methane, hydrogen sulfide or coal gas, and the single blowout quantity of combustible gas can not lead to the intake pipe in too big in being in the calculated value, and adjusts the air pressure in the intake pipe through solenoid valve 11, avoids appearing the explosion.

The inner side wall of the automobile air inlet pipe, the heating net 4, the straight rod 5, the preheating net 6, the spray gun 7, the telescopic rod 8, the push plate 9, the reset spring 10, the fan plate 11 and the push sheet 12 are coated with fireproof coating, so that the structure cannot be damaged when inflammable gas is combusted.

The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
