As everyone knows, motor operationally can produce amount of heat, and in existing natural aspiration petrol engine, no matter be domestic or imported auto, all only be utilized less than the heat energy of 30%, the heat energy of about 40% is with exhaust mode loss, and about 30% is depleted in engine cooling procedure, and this represents that therefore the available power up to 70% is wasted.Conventional diesel engine is due to high compression ratio, and engine expansion efficiency is used effectively, and its thermal efficiency is also only had an appointment and 37%. at present also only had with the highest heat utilization rate of internal-combustion engine 40% more in the world, still has a large amount of heat energy with waste gas and type of cooling waste.If so numerous heat energy effectively can be utilized, the utilization rate of the energy can be allowed to rise to higher degree.
What all trades and professions used with petroleum products is the internal-combustion engine of fuel is actually one petroleum products burnt and is converted to the mechanical system of heat energy, energy is not operationally changed by a large number, in fact the heat energy produced that burns wasted in a large number, no matter be domestic or imported product, all only be converted into utilization of mechanical energy less than the heat energy of 30%, the heat energy of about 40% is with exhaust mode loss, about 30% is depleted in engine cooling procedure, and this represents that therefore the available power up to 70% is wasted.
At present, some large motor corporations are all in the research carrying out this respect in the world, but not yet release practical product.
Bayerische Motorne Werke Aktiengeellschaft of Germany was proposed the imagination utilizing discarded remaining thermogenetic high pressure steam booster engine bent axle in 2012, and input research experiment.In this imagination, the assistant force drive device of a certain volume must be installed additional at the crankshaft front end of motor.The power of its imagination produces and utilizes principle as follows:
Waste gas (600 DEG C-1000 DEG C) heats steam boiler → generation high pressure steam → steam line → bent axle steamturbine booster → radiator (the steam condensation) → high pressure micro pump → steam boiler be installed near silencing apparatus.
Steam turbine generator is just installed additional on its hybrid vehicle in Toyota Company of Japan, carries out discarded waste heat and produces the experiment of high pressure steam driving generator.Then the power delivery sent by generator is to the battery pack of hybrid vehicle.Its power produces and utilizes principle as follows:
Waste gas (600 DEG C-1000 DEG C) heats steam boiler → generation high pressure steam → steam line → steam turbin generator → radiator (the steam condensation) → high pressure micro pump → steam boiler be installed near silencing apparatus
The research of Bayerische Motorne Werke Aktiengeellschaft is that thermal power is acted on 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 also have 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 the mechanical component that motor and speed changer etc. need operationally to consume some mechanical energy, make mechanical friction loss little, energy utilization rate can be further improved.
Main target is concentrated on generator cogeneration aspect by the researcher of domestic many enterprises and R&D institution 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 two times transfer is not very desirable.
