The utility model provides a quick start warm-up device of air-cooled internal-combustion engine of high altitude environment of low temperature, includes internal-combustion engine 12, is equipped with cylinder body cooling air duct 1, cylinder body heat dissipation air intake 2, internal-combustion engine air inlet chamber 8 and mechanical fan heat dissipation air intake 9 on the internal-combustion engine 12, its characterized in that: the air quantity control device is arranged opposite to the heat dissipation air inlet 2 of the cylinder body and comprises a rear air baffle 3 and a front sealing plate 6, the rear air baffle 3 and the front sealing plate 6 are connected together through a stainless steel hinge 5, the rear air baffle 3 is provided with a rear air baffle air inlet 4, the front sealing plate 6 is provided with a shutter 7, the front sealing plate 6 is fixedly provided with an electromagnet 10, the rear air baffle 3 is fixedly provided with a permanent magnet 11, the front sealing plate 6 is fastened in the middle of an air inlet cavity 8 of an internal combustion engine 12, a temperature sensor 13 is arranged at a cylinder head of an internal combustion engine 12, the temperature sensor 13 is connected with the end 1 of a signal input end of a temperature controller 14 through a signal wire 15, the end 2 of the temperature controller 14 is connected with a 12V input power supply to provide a working power supply for the temperature controller 14, and the end 3 of the temperature controller 14 is connected with a coil of an electromagnet 10 through an output power wire 16 to control the movement of a rear windshield 3. The temperature controller 14 adopts an XH-W3002 temperature controller.
The working principle of the invention is as follows: when the internal combustion engine 12 is started, because the viscosity of the engine oil is very high in a low-temperature environment, the starting resistance moment is increased, the air inlet quantity entering the heat dissipation air inlet 2 of the cylinder body is controlled through the rear wind shield 3, the air in the cooling air duct 1 of the cylinder body is stored through the heat generated by starting the internal combustion engine 12, the cylinder body is warmed, the thermal energy is recycled, the viscosity of the engine oil in the internal combustion engine 12 is reduced, the internal combustion engine is started quickly, and the loss is reduced.
The working process of the invention is as follows: firstly, setting the stop temperature of a temperature controller 14, for example, 30 ℃, when an internal combustion engine 12 is started, simultaneously electrifying the temperature controller 14, detecting the cylinder temperature of the internal combustion engine 12 by the temperature sensor 13 by the temperature controller 14, when the temperature is lower than a set value, outputting a 12V power supply to a coil of an electromagnet 10 by the temperature controller 14, enabling the electromagnet 10 to work, because a rear windshield plate 3 and a front seal plate 6 are connected together by a stainless steel hinge 5, enabling the electromagnet 10 to generate the same polarity as a permanent magnet 11 according to homopolar repulsion and heteropolar attraction characteristics, pushing the permanent magnet 11 away in the direction of the magnet stress, pushing the rear windshield plate 3 away at the same time, after the internal combustion engine 12 is started, cold air from a heat dissipation air inlet 9 of a mechanical fan enters between the rear windshield plate 3 and the front seal plate 6, a large amount of cold air passes through a shutter 7 of the front seal plate 6 and is discharged out of a cabin, and only a small amount of cold air enters a cylinder cooling air duct 1 from a heat dissipation air inlet 4 of the rear windshield plate through a cylinder cooling air inlet 2, the heat in the cylinder cooling air duct 1 in the internal combustion engine 12 flows around the cylinder, the temperature of the cylinder rises, the viscosity of the engine oil is reduced, the starting time is shortened, the heat can be recycled, the energy can be saved, and the waste of fuel is reduced. When the internal combustion engine 12 is normally started and the temperature of the cylinder body rises to a set value of 30 ℃, the temperature controller 14 cuts off a coil power supply of the electromagnet 10, the electromagnet 10 stops working, the wind baffle 3 automatically withdraws, cold air in the heat dissipation air inlet 9 of the mechanical fan completely enters the cylinder body cooling air channel 1 from the air inlet 4 of the rear wind baffle through the heat dissipation air inlet 2 of the cylinder body, and the internal combustion engine enters a normal cooling state.
