Abstract

The utility relates to an automobile preheater. The middle part of a gas exhaust piping of an automobile is designed to be a firebox. The side wall of the firebox is a water jacket structure. A water outlet and a backwater gap of the water jacket are connected with an engine cooling system by a hose to form a circulation loop. A stream guidance water pump is arranged in the backwater gap. An oil tank is connected with an oil transfer pump by a pipeline. The oil transfer pump is connected with a check valve by an oil delivery pipe. The other end of the check valve is connected with a nozzle in the firebox. The nozzle is provided with an electronic igniter. The utility model makes the best of the space and the structure of an automobile draught flue for hydronic heating the engine cooling system, controls the length of the flame and tempering of burning flame by the check valve and a gas mixture pump, thus ensuring the safe burning. Part of heat can directly enters into a cylinder by an exhaust valve to further increase heating effect; and efficient preheating can be carried out on an air intake branch by an overlapping opening valve.

Description

Vehicle preheater

Technical field: the utility model relates to a kind of vehicle preheater.

Background technique: automobile cycling start difficulty in the winter time, easily frayed, the heater on the existing market is based on electric heater.Adopt the heater of DC electrical source, limited by the storage battery electric weight, heats is not obvious, even some effects are arranged, has not also strengthened the wearing and tearing of automobile because heating-up temperature is not high.The data record is arranged, and subzero 5 degree of automobile---the temperature-rise period of 80 degree is equivalent to the wearing and tearing of 300 kilometers distances of automobile running.Adopt the electric heater of 220 volts of power supplys too to rely on power supply, be difficult to practicality in the open air.

Summary of the invention: mechanical wear when the purpose of this utility model provides a kind of reduction gas car, improve the vehicle preheater of thermal conversion efficiency.The purpose of this utility model is achieved through the following technical solutions: the utility model is a kind of vehicle preheater, be arranged to a firing chamber in the automobile exhaust pipeline, sidewall of combustion chamber is a jacket structure for water, the water outlet of water jacket and backwater mouth are connected to form circulation loop by flexible pipe and engine-cooling system respectively, at the backwater mouth place water conservancy diversion water pump is set, fuel tank connects oil transfer pump by pipeline, oil transfer pump connects back only valve by fuel supply line again, return to end the valve the other end and be connected, ignition is installed on the nozzle with nozzle in the firing chamber.The utility model makes full use of the space and the structure of automobile exhaust flue, has designed a jacket heating system, and to the engine-cooling system heating that circulates, fuel is directly provided by automotive oil tank.Import back fuel only by oil transfer pump during use that valve enters nozzle, initial igniter makes fuel in the firing chamber internal combustion, with the motor heating, realizes the purpose of engine warming up under the effect of circulating water.The utility model is grown and tempering by returning the flame that ends valve and mixed steam air pump control combustion flame, thereby guarantees safe combustion.Because the firing chamber is located in the engine exhaust pipe, free space is bigger during burning, can guarantee the abundant mixed combustion of combustion gas, adopts the air pump oxygen supply simultaneously, improves combustion efficiency.Firing chamber one end is for dividing flue, pressurized machine, and exhaust valve can effectively stop flame, and the other end connects silencing apparatus, has the Mars of extinguishing effect equally.A part of heat of the present utility model can directly enter cylinder through exhaust valve, and heats is further improved, and opens valve and can also carry out effective preheating to air intake branch through folded.
