Description
Technical field
The present invention relates to a kind of power system, particularly a kind of pneumatic---fuel mixed power system.
Background technology
Constantly soar and the fuel-engined vehicle environmental pollution of fuel price constantly increase the weight of to make countries in the world all stepping up to research and develop new-energy automobile.Air motor, does not need to consume petroleum as working medium with pressurized air and liquid nitrogen in the course of the work, can realize zero-emission, is a kind of developing direction.Yet air motor faces the low technical bottleneck of this energy utilization efficiency at present, and adopts pneumatic---fuel hybrid can carry out organically combination with air motor and combustion engine, forms complementary effect.At present, Chinese patent [CN1398740] and Chinese patent [CN101225767] are described pneumatic---and the main utilization of fuel mixed power system is the air inlet that the heat output with the high-temperature exhaust air of combustion engine and combustion engine is used to heat air motor, thereby reach the purpose that improves energy utilization efficiency, yet, the heat of traditional combustion engine about 30% liquid that is cooled is taken away, and this pattern does not use the entrained heat of cooling liquid of IC engine.Pneumatic in order to allow---fuel mixed power system has high-energy degree of utilization and good cooling performance simultaneously, must a kind of new mixed mode of design.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of pneumatic---fuel mixed power system.
Above-mentioned purpose is achieved through the following technical solutions:
Provide a kind of pneumatic---fuel mixed power system, comprise air motor and combustion engine, the gas tank that stores high pressure gas connects H Exch, balance chamber and air motor successively by pipeline; The cooling system of described combustion engine is by pipeline and water pump and H Exch formation circulation loop.
As a kind of improvement, the cooling system of described combustion engine comprises refrigerant fluid and the cooling liquid of IC engine circulating system in water tank of internal-combustion engine, the water tank.
As a kind of improvement, described water pump links to each other with the bent axle of combustion engine, drives running by I. C. engine crankshaft.
Beneficial effect of the present invention is:
The refrigerant fluid of combustion engine is introduced in the H Exch by pipeline, heated pneumatic engine charge, when improving air motor dynamic property and economy, reduced the load of internal-combustion engine cooling system with the entrained heat of refrigerant fluid.Under possible situation, even can save the radiator and the cooling fan of traditional combustion engine, for the simplification of internal-combustion engine cooling system provides the foundation by coupling design.
Description of drawings
Fig. 1 is the scheme drawing of hybrid power system among the present invention.
Reference numeral: air motor 1, combustion engine 2, gas tank 3, H Exch 4, balance chamber 5, the water pump 6 of storage high pressure gas.
The specific embodiment
The pilot system of present embodiment as shown in Figure 1.
Pneumatic in the present embodiment---fuel mixed power system comprises air motor 1 and combustion engine 2, and the gas tank 3 that stores high pressure gas connects H Exch 4, balance chamber 5 and air motor 1 successively by pipeline; The cooling system of described combustion engine 2 is by pipeline and water pump 6 and H Exch 4 formation circulation loops.
By appropriate design thermal exchange coupling, can save the radiator and the cooling fan of traditional combustion engine.
The working process of the cooling system of traditional combustion engine is: water pump is driven by I. C. engine crankshaft, in the coolant circulation system of water pump with the refrigerant fluid suction combustion engine in the water tank of internal-combustion engine, combustion engine is cooled off and absorbs heat, by the radiator reflow tank, the entrained heat of refrigerant fluid then is dispersed in the environment by radiator and cooling fan at last.The present invention is to being improved on the basis of this structure: refrigerant fluid is behind process cooling liquid of IC engine circulating system, by the pipeline inflow heat exchanger, the heat that it is entrained passes to high pressure gas by heat exchanger, realization is to the air inlet heating of air motor, afterwards again by the pipeline reflow tank.Simultaneously, water pump still links to each other with I. C. engine crankshaft, and its rotating speed and I. C. engine crankshaft rotating speed are proportional, can satisfy the demand of different operating mode exchange heats.When high pressure gas are heated, cooling liquid of IC engine will it is entrained the heat transferred high pressure gas, therefore, this arrangement has just been realized the effect of radiator and cooling fan in the traditional combustion engine cooling system, adopt this arrangement, just can omit the cooling fan and the radiator of traditional combustion engine, reach the purpose of simplifying internal-combustion engine cooling system.
At last, it is also to be noted that what more than enumerate only is a kind of specific embodiment framework of the present invention.Obviously, the invention is not restricted to above embodiment.All distortion that all those of ordinary skill in the art can directly derive or associate from content disclosed by the invention all should be thought protection scope of the present invention.
