Background technique
As everyone knows, motor can produce amount of heat in the time of operation, and in existing natural aspiration petrol engine, no matter be domestic or imported auto, all only be utilized less than 30% heat energy, approximately 40% heat energy is with exhaust mode loss, and approximately 30% is depleted in engine cooling procedure, and therefore this expression wastes up to 70% the available energy.Conventional diesel engine is due to high compression ratio, and motor expansion efficiency is used effectively, and its thermal efficiency also only has an appointment 37%.Also only having 40% morely with the highest heat utilization rate of internal-combustion engine in the world at present, still having a large amount of heat energy with waste gas and type of cooling waste.If numerous heat energy effectively can be utilized, can allow the utilization rate of the energy rise to higher degree.
The internal-combustion engine taking petroleum products as fuel that all trades and professions are used is actually a mechanical system of petroleum products being burnt and being converted to heat energy, it does not change energy in a large number in the time of work, in fact the heat energy that burning produces wasted in a large number, no matter be domestic or imported product, all only be converted into utilization of mechanical energy less than 30% heat energy, approximately 40% heat energy is with exhaust mode loss, approximately 30% is depleted in engine cooling procedure, and therefore this expression wastes up to 70% the available energy.
At present, some large motor corporations are all in the research of carrying out this respect in the world, but not yet release practical product.
Bayerische Motorne Werke Aktiengeellschaft of Germany has released the imagination of utilizing discarded remaining thermogenetic high pressure steam booster engine bent axle in 2012, and input research experiment.In this imagination, must install at the crankshaft front end of motor the assistant force drive device of a certain volume additional.The power of its imagination produces and utilizes principle as follows:
Waste gas (600 DEG C-1000 DEG C) heating is installed near steam boiler → generation high pressure steam → steam line → bent axle steamturbine booster → radiator (steam condensation) → high pressure micro pump → steam boiler silencing apparatus.
Steam turbine generator is just installed additional on its hybrid vehicle in Toyota Company of Japan, discards waste heat and produces the experiment of high pressure steam driving generator.Then the power delivery of generator being sent is to the battery pack of hybrid vehicle.Its power produces and utilizes principle as follows:
Waste gas (600 DEG C-1000 DEG C) heating is installed near steam boiler → generation high pressure steam → steam line → steam turbin generator → radiator (steam condensation) → high pressure micro pump → steam boiler silencing apparatus.
The research of Bayerische Motorne Werke Aktiengeellschaft is that thermal power is acted on to engine crankshaft, and in engine operation process, the mechanical friction of the connecting rod of motor and distribution device, speed changer will consume portion of energy, and the energy can not get maximum utilization.The steamturbine of Toyota Company is used for producing electric energy on hybrid vehicle, and energy has also passed through twice conversion, and the energy loss in transfer process can't neglect equally.Motor car engine steamturbine power-assisted driving system directly acts on automotive transmission rear end, avoid motor and speed changer etc. and need in the time of operation, consume the mechanical component of part mechanical energy, make mechanical friction loss little, energy utilization rate can be further improved.
The researcher of domestic many enterprises and R&D institution concentrates on main target generator cogeneration aspect at present, namely heat energy is directly converted to electric energy, does not carry out the direct conversion of heat energy to kinetic energy.Because energy has partial loss in each transfer process, the final utilization ratio after secondary is changed is not very desirable.
