Abstract: The new type engines without the combustion process have to
be researched and manufactured, especially for China, because of urban
pollution and the short of fossil oil. Air powered engines, for example
pressed air engine, liquid nitrogen engine and liquid air engine, are
definitely zero emission engines, and have attracted the attention of
government and the researcher. The theoretical analysis of the work
cycle is made for the pressed air engine and liquid nitrogen engine.
According to the calculation results of the available energy, the
influence of the initial pressure and temperature of the expansion
process to output energy is discussed, and the optimism method of the
work cycle of the liquid nitrogen engine is described.
Key words: Air powered engine Available energy Work cycle
