Because highlands height above sea level (bar pressure is low), oxygen content in air is few, day and night temperature is large, cold season is long, diesel engine intake temperature and intake pressure are descended simultaneously, cause the temperature and pressure that compression ends in the cylinder of diesel engine to descend, cause the interior mixture gas of cylinder and combustion conditions out of reach diesel engine to be lighted and the afterflame requirement.In addition, along with the reduction of ambient temperature, the horsepower output of storage battery also correspondingly descend (30 ℃ time, output rating descends about about 60%), cause diesel engine starting system power to descend, make diesel engine fail to start or can not start reliably under the low temperature in plateau condition.In addition, it is very slow to cause slowly operator's compartment to heat up in the water temperature rising of engine starting initial stage cold season, and the heating amount is obviously not enough, causes operator's compartment defrosting difficulty, and the front windshield frosting is serious, has a strong impact on driver comfort and travel safety.In sum, because vehicle can't start and the operator's compartment heating effect is relatively poor, cause vehicle normally to use, and caused huge economic loss.
At present, China plateau and cold district's active service diesel vehicle, almost 100% is equipped with the cold start ancillary method.The cold start ancillary method that adopts mainly contains glow plug, PTC pottery charge heating, flame charge heating, battery warmer etc.But, traditional diesel engine cold start ancillary method can not adapt to Plateau Cold Area inclement weather environmental conditions, especially in plateau (more than the 3000m) and severe cold (below 41 ℃) area, the cold-starting device of vehicle outfitting and equipment are not suitable with the low temperature environment of Plateau Cold Area, and vehicle is difficult to smoothly starting.
The utility model content
The utility model will solve plateau and cold district's vehicle launch and operator's compartment heating problem, and a kind of vehicle infrabar cold post-start and operator's compartment heating system are provided.
The utility model vehicle infrabar cold post-start and operator's compartment heating system, comprise fule heater, temperature sensor, automatically controlled chip, operator's compartment temperature booster and heater unit, fule heater outlet connects respectively operator's compartment calorifier inlets and engine room entrance by heating pipeline independently and cold-starting pipeline, the operator's compartment heater outlet connects the fule heater entrance by the individual heating loop, and the engine room outlet connects and the fule heater entrance by the cold-starting loop; The engine room outlet is by thermal cycle pipeline connecting engine chamber inlet, and the thermal cycle pipeline sets gradually radiator, threeway and water pump, and the engine room outlet connects the operator's compartment calorifier inlets by the dependent heating pipeline that valve is set; Automatically controlled chip connects respectively fule heater and temperature sensor, and temperature sensor and fule heater are adjacent.
Between described individual heating loop and cold-starting loop and the fule heater entrance water-circulating pump is set.
Described engine room outlet connects respectively thermal cycle pipeline and cold-starting loop by coolerstat.
The utility model has the advantages that: the utility model is applicable to cold plateau area diesel engine utmost point cold post-start and operator's compartment heating; Fule heater has been realized reliable ignition and afterflame under high altitude anoxia and extremely low temperature condition; And can realize the automatic control of fule heater working process, can carry out according to cooling-liquid temperature the fuel feeding control of fule heater; Have that cost is low, easy to use, the characteristics of reliable operation.
This device can greatly improve diesel equipment plateau and cold district starting ability, is simultaneously the operator's compartment heating.Be embodied in, the smoothly quick heat engine starting of auxiliary diesel reduces engine wear, increasing service life of engine, reduce fuel oil and service expenditure; Improve the operator's compartment temperature, improve the chaufeur service conditions, improve plateau, cold district travel safety, have larger society and economic benefit.
Device all can start by the auxiliary diesel vehicle on the spot and under the 5000m bar pressure of laboratory simulation and-41 ℃ of cryogenic conditions smoothly on the plateau, and starting ability all obviously is better than equipping the diesel vehicle of PTC pottery air inlet heating device and flame air inlet heating device.Install easy for installation, use simple and reliablely, starting effect is good, is fit to very much carry out the market promotion.
