Abstract
The invention relates to an automobile pre-heater, a combustion chamber is arranged in the middle portion of a gas exhaust pipeline of the automobile, the lateral wall of the combustion chamber is a water jacket structure, a water outlet and a backwater opening of the water jacket are connected with an engine cooling system via a hose to form a circulation pipeline, a guide water pump is mounted at the backwater opening, an oil tank is connected with an oil conveying pump via a pipeline, the oil conveying pump is connected with a check valve via an oil supply pipe, the other end of the check valve is connected with a nozzle in the combustion chamber, and the nozzle is equipped with an electronic igniter. The automobile pre-heater sufficiently utilizes the space and the structure of an automobile draught flue to circularly heat up the engine cooling system, the flame length and the backfire of combustion flame are controlled by the check valve and a mixing gas pump, thereby guaranteeing safe combustion, one part of heat energy can directly enter a cylinder via an exhaust valve, further increasing the heating effect, and efficiently preheating an air intake branch via a lapping valve.
Description
Technical field:
The present invention 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 invention is to provide a kind of reduction gas car improves the vehicle preheater of thermal conversion efficiency.The objective of the invention is to be achieved through the following technical solutions: the present invention 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 present invention 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 present invention grows 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 invention 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.

Embodiment:
The present invention as shown in Figure 1 is a kind of vehicle preheater, be arranged to a firing chamber 1 in the automobile exhaust pipeline, firing chamber 1 sidewall is a jacket structure for water, the water outlet 3 and the backwater mouth 4 of water jacket 2 are connected to form circulation loop by flexible pipe and engine-cooling system 5 respectively, 4 places are provided with water conservancy diversion water pump 6 at backwater mouth, fuel tank 7 connects oil transfer pump 8 by pipeline, oil transfer pump 8 connects back only valve 10 by fuel supply line 9 again, return to end valve 10 the other ends and be connected installation ignition 12 on the nozzle 11 with nozzle 11 in the firing chamber.Nozzle 11 connects supply air line 13, the supply air line 13 terminal mixed steam air pumps 14 that connect.As shown in Figure 2, described firing chamber water jacket 2 structures are that the sidewall internal fixation is arranged standpipe 15 more, and as shown in Figure 3, every standpipe 15 all is connected to form with firing chamber 1 exterior edge face transverse tube 16.
