The side wall of the combustion chamber is a water jacket structure. Pipeline, a diversion pump is installed at the water return port, the fuel tank is connected to the fuel pump through the pipeline, and the fuel pump is connected to the check valve through the fuel supply pipe, and the other end of the check valve is connected to the nozzle in the combustion chamber, and an electronic igniter is installed on the nozzle . The utility model makes full use of the space and structure of the automobile exhaust flue to circulate heat the engine cooling system, and the flame length and tempering of the combustion flame are controlled by the check valve and the mixed gas-air pump, so as to ensure safe combustion, and part of the heat can pass through The exhaust valve directly enters the cylinder, which further improves the heating effect, and the intake branch pipe can be effectively preheated by stacking the valve.

Description

car preheater

Technical field: The utility model relates to an automobile preheater.

Background technology: Cars are difficult to start in winter and are prone to wear and tear. Electric heaters are the main heaters in the existing market. The heater using DC power supply is limited by the power of the battery, and the heating effect is not obvious. Even if there is some effect, it will be increased because the heating temperature is not high, and the wear and tear of the car will be increased. According to records, the heating process of a car from minus 5 degrees to 80 degrees is equivalent to the wear and tear of a car traveling 300 kilometers. The electric heater adopting 220-volt power supply is too dependent on the power supply, so it is difficult to be practical in the field.

SUMMARY OF THE INVENTION: The purpose of this utility model is to provide an automobile preheater which reduces mechanical wear and improves heat conversion efficiency during gas-car. The purpose of the utility model is achieved through the following technical proposals: the utility model is an automobile preheater, a combustion chamber is arranged in the exhaust pipeline of the automobile, the side wall of the combustion chamber is a water jacket structure, and the water outlet of the water jacket The water return port is connected to the engine cooling system through hoses to form a circulation pipeline. A diversion pump is installed at the water return port. The fuel tank is connected to the oil delivery pump through the pipeline. One end is connected to the nozzle in the combustion chamber, and an electronic igniter is installed on the nozzle. The utility model makes full use of the space and structure of the exhaust flue of the automobile, and designs a set of heating system, which circulates and heats the engine cooling system, and the fuel is directly provided by the automobile oil tank. When in use, the fuel is fed into the check valve into the nozzle by the fuel pump, the igniter is started to burn the fuel in the combustion chamber, and the engine is heated under the action of circulating water to achieve the purpose of engine preheating. In the utility model, the flame length and tempering of the combustion flame are controlled by a check valve and a mixed steam pump, so as to ensure safe combustion. Since the combustion chamber is located in the exhaust pipe of the engine, there is a large space available for combustion, which can ensure that the gas is fully mixed and combusted. At the same time, an air pump is used to supply oxygen to improve combustion efficiency. One end of the combustion chamber is divided into a flue, a supercharger, and an exhaust valve, which can effectively prevent flames, and the other end is connected to a muffler, which also has the effect of extinguishing sparks. A part of the heat of the utility model can directly enter the cylinder through the exhaust valve, so that the heating effect is further improved, and the intake branch pipe can be effectively preheated by stacking the valve.
