摘要:奎西发动机有很大可能彻底改变汽车工业,减少我们对外国石油的依赖。 设计是一个环保概念,有助于改善全球变暖的问题。在关于燃料动力方面,我们还需要做许多努力。
ith respect to their given power output. The Quasiturbine weighs approximately ¼ as much as the conventional engine and 1/6th as much as electric power. This factor when combined with the compact design allows for different car configurations in which the overall weight of the car can be significantly reduced. This in turn would tremendously increase the fuel mileage of vehicles. (QT Advantages Efficiency)
Other factors concerning automotive engineers are vibration, noise, and pollution. Since the Quasiturbine engine is perfectly balanced, there is no resulting vibration. Vibration and noise are both reduced by the gradual evacuation of gasses and a greater angular displacement. Furthermore, the expansion of gasses is split into four which allows for smoother operation. The four chambers allow a shorter confinement time for gasses, which will help to eliminate NOx emissions. High pressure, temperature and confinement times all lead to NOx emissions. The Quasiturbine expansion starts quicker than other engines which produce lower initial temperatures and pressures and the confinement time is greatly reduced. The overall result is a smoother, quieter, and cleaner engine. (QT Theory Engine Problematic)
Rising fuel costs are a concern for everyone. With the hope to reduce and eventually eliminate the dependence on oil, alternative fuels have become a major interest among auto manufactures. The Quasiturbine is able to efficiently operate on methanol, gas, diesel, hydrogen, and even water with simple modifications. An earlier expansion process means an end to fuel additives to prevent detonation and a beginning to new fuel uses. 'The Quasiturbine meets the fundamental criteria imposed by the 'hydrogen' engine of the future (cold intake area, stratified intake, reduced confinement time, low sensitivity to detonation, less pollutant, robust and energy efficiency), and even surpasses the Wankel in this respect, since the intakes are separated by 3 strokes instead of two. Frequent instabilities in the combustion of hydrogen should not appreciably affect the Quasiturbine, as it is not sensitive to detonation.' (QT Theory Piston Differences) Water injection can be used to operate the QT like the steam engine, but without the risk of explosion. Liquid water can be directly injected into a hot Quasiturbine where it will flash steam and propel the engine. This process would be ideal to use in a fuel conversion mode where the combustible fuel would be shut off when the engine is hot enough to operate on water. Then when the temperature cools, the fuel could be introduced again. These factors could greatly reduce, if not eliminate, our dependency on foreign oil.
So far, it seems that the Quasiturbine may be the perfect solution over HCCI, clean Diesel and gasoline, for eliminating America's dependency on oil. This however may not be the case. Although the proposed engine may seem to be perfect, it does have some shortcomings. One such factor is the infancy of the technology. Mankind has been perfecting the I.C.E. for the past 100 years, and the Quasiturbine was unveiled in 1996. This infancy is shared with the hydrogen fuel cell, with respect to a lack of technological advancements which make the proposed solutions a poor replacement for current technologies. Clean diesel is deemed by many sources to be the next advancement in power train technology; however, the dependency on oil remains. Th
