Pursue the epoch convenient, fast, traffic is flourishing current people, automobile becomes the important vehicle that generally use both at home and abroad, only on the Chinese side, the automobile using just has more than 200,000,000, in addition, 20,000,000, the automobile of annual new production, approximately 500,000,000 tons of the annual fuel oils consuming of vehicle of these use fuel oils, are worth approximately five trillion yuan Renminbi.But data shows: the world oil reserves of having verified are enough a century left and right that uses only.Be in now worldwide energy scarcity stage, especially China, situation is even more serious: China is petroleum import big country, and the oil of about half will rely on import.Some scholarly forecasts: if war occurs in bay, if especially Iran has blocked hereby straits of Hall wood, oil price is at least doubled.Fuel price becomes one of key factor of left and right price.Since combustion engine comes out, just there is the not high problem of heat efficiency, even if utilize current state-of-the-art for oil tech---electric spray type fuel feeding, also can only reach 20% left and right, be that most fuel oils do not do useful work, also there is the problems such as exhaust emissions exceeds standard, pollutant atmosphere in this, especially we have realized that in the situation of " vehicle exhaust is the major reason that causes thick weather ", will focus on especially " energy-saving and emission-reduction " problem of these heavy polluters simultaneously.Country all takes out research and development and the production of extensive fund support " energy-saving and emission-reduction " type technology innovation product every year.We know: it is 80 DEG C that automotive engine is preferably operated in system temperature, and driving engine is in optimum Working when the time comes, the most fuel-efficient and horsepower output is large.But, domestic and international various automobile ubiquity at present: when initial stage travel phase or ambient temperature are low, the air themperature that enters driving engine is low, system heats up slow, and when following lower than 0 DEG C, also there is over cooling problem in ambient temperature.For example: with the actual measurement of the domestic import type of certain money car, be-10 DEG C in ambient temperature, at the uniform velocity travel 1 hour with 70 kilometers of speed per hours per hour, system temperature can only reach 55 DEG C.This just causes excessive fuel consumption and unfavorable to driving engine.The patent No. is 201310325748.4 invention, a kind of energy saver that improves automotive engine mixture gas atomization level is disclosed, mainly that air heating to a 50 DEG C left and right that enters driving engine is beneficial to fire oil atomization, and for abundant atomization leaves the time, fuel injector is moved to inlet manifold head end from inlet manifold end, there is certain energy-saving effect, but its thermal source is taken from the refrigerant fluid of driving engine, still consume a small amount of energy and a little excessive fuel consumption is not very good.Especially it is all the more so when ambient temperature is low.We know, the winter of China northern territory, temperature is usually low to moderate below-20 DEG C, only the hot car of idling just needs more than 15 minutes, and this hot car stage need to be compared with dense mixture gas and very excessive fuel consumption has the vehicle of heating function particularly to have the public transit vehicle of heating function, need to increase fuel consumption to support heating, meanwhile, the heat energy of tail gas does not but utilize and has slatterned.

Summary of the invention:

The technical problem to be solved in the present invention is open a kind of new device that utilizes motor exhaust used heat to be heated to 80 DEG C of, reductions of discharging energy-conservation to improve fuel thermal efficiency, environmental protection to entering the air of driving engine and cooling system.

The scheme of technical solution problem of the present invention is:

1, utilize the used heat of automobile engine tail gas, reach 80 DEG C of cooling systems with front engine and heat entering the air of driving engine and operating temperature, to air heating, be conducive to fire oil atomization, make it enter into as early as possible optimum Working to heating engines and enter into as early as possible the most fuel-efficient mode of operation, especially, when ambient temperature is low, its energy-saving effect clearly.In the time that engine system temperatures reaches 80 DEG C, the air themperature that enters driving engine can reach 70-80 DEG C, be that driving engine has entered optimum regime, do not need to continue to have heated, and for preventing engine overheat, turn round and utilize siphon principle that the cooling media anti-freezer of waste heat collector wind is all back to and in storage box, excised heating by stopping liquid pump, recovered former design point, namely energy-conservation, reduce discharging, when environmental protection, not only do not affect power output, on the contrary because of fully atomization, it is fully calcined that the factor such as lubricated good is conducive to raising and the fuel oil of power, reduce carbon deposit and extended engine life.

2, set up an adjustable windscreen that stops area at the windward side of radiator, this windscreen all blocked radiator at the engine operation initial stage, when system temperature reaches 80 DEG C, this windscreen all exits, the former design point that returns to this car, this just can realize: make driving engine enter as early as possible optimum Working and energy-conservation.Its control can be automatic, also can be manual, but taking automatically+manually as good.

The present invention is applied widely, and all various automobiles are all suitable for, and serviceability is safe and reliable, detects and has obvious energy-saving effect through reality.
