People choose cars as a means of transportation when they go out. It is difficult for a car to start and drive in a low temperature environment, because the cold temperature makes the oil inside the engine accumulate at the bottom of the engine, which cannot lubricate in time, and the engine cannot completely vaporize the gasoline before the engine reaches the normal operating temperature, resulting in energy waste and Security risks. According to investigations: when most people start their cars in low temperature environments, they start the engine idling to provide heat, and start driving after reaching the normal operating temperature of the engine. This method not only takes a long time, but also has low efficiency and wastes gasoline energy.

detailed description

The utility model will be further described below in conjunction with embodiment (accompanying drawing).

As shown in Figure 1, the automobile low-temperature starting and running device of the present utility model includes a water tank 1, and the circulating water of the main circuit of the water tank enters the internal water channel of the engine through the first electromagnetic valve 2, and enters through the second electromagnetic valve 4 along the outlet of the engine 5 water channel. Water tank 1; an oil combustion chamber 3 for heating circulating water is provided between the water tank 1 and the engine 5, and the circulating water outlet of the oil combustion chamber 3 is connected with the first electromagnetic valve 2, and the oil combustion chamber The circulating water inlet of 3 is connected with the second solenoid valve 4, and a temperature controller 14 is arranged on the pipeline connected with the second solenoid valve 4 at the outlet of the engine 5 waterway; the combustion waste gas of the oil combustion chamber 3 is connected to the engine bottom lubricating oil piping system b; the heat collector 6 located in the engine exhaust pipe 7 is connected to the auxiliary heating water tank 11 through a heat conduction line 8; the water inlet of the auxiliary heating water tank 11 is connected to the The outlet of the waterway of the engine 5 is connected, and the water outlet of the auxiliary heating water tank 11 is connected with the second electromagnetic valve 4 through the water pump 13 and the temperature controller 14 in sequence (after the circulating water comes out through the waterway of the engine, it enters the auxiliary heating water tank 11, and then is heated at the temperature controller 14 and merge into the main road circulating water pipeline).

The utility model is provided with a multi-function monitor 12 in the auxiliary heating water tank 11, and the multi-function monitor 12 is connected with the corresponding control terminals of the heat conduction controller 9, the third electromagnetic valve 10 and the water pump 13 respectively through an electrical connection mode. connect.

More specifically, the utility model heats the circulating water in the water tank 1 by adding equipment so that the circulating water can provide heat to the engine 5. This heating system is composed of a main circuit circulating water heating system and an auxiliary circuit heating water circulation system. The road heating cycle system is composed of the first solenoid valve 2, the oil combustion chamber 3, the second solenoid valve 4 and the temperature controller 14 connected to the main road circulating water pipeline. When the temperature controller 14 detects that the water temperature in the main road circulating water pipe is lower than At a certain value, control the second solenoid valve 4 and the first solenoid valve 2 to open at the same time, so that the circulating water temporarily does not pass through the water tank 1, directly flows into the oil combustion chamber 3, and is ignited and heated by the relevant oil, quickly providing heat to the circulating water to make it warm up , and then enter the main circuit circulating water pipe through the first electromagnetic valve 2, flow into the internal water channel of the engine, heat the engine 5 and the bottom lubricating oil, and make the temperature rise rapidly to the normal operating temperature.
