目前,节约发动机的燃料已成为一个重要的课题,在考虑它的措施时自然想到要减少占能量损失大部分的冷却损失和排气损失,以及这些能量的有效利用。作为具体方案之一的绝热发动机、尤其是美国寇明斯公司(R.卡莫)等利用陶瓷绝热材料减少发动机的散热,用排气涡轮把排气的高能量转变成功,其中的一部分供增压器用,余下的部分增加轴功率输出。采用这个方法后可使耗油率接近120克/马力时。现介绍这种发动机以下几个方面的问题,供读者参考。
At present, saving fuel for the engine has become an important issue. Naturally, when considering its measures, it is necessary to reduce the cooling loss and exhaust loss that account for most of the energy loss, as well as the effective utilization of these energies. As one of the specific solutions of adiabatic engines, especially the United States Cummins (R. Carmo) and other use of ceramic insulation materials to reduce engine cooling, the exhaust gas turbine to high-energy conversion success, some of them for the increase Pressure vessel, the remaining part of the increase in shaft power output. Using this method can make the fuel consumption close to 120 grams / horsepower. This engine is now introduced the following aspects of the problem for readers reference.
