Originally invented as a means of making steam engines more efficient, the compounding of engines by use of several stages has also been used on internal combustion engines and continues to have niche markets there. The stages of a compound engine may be either of differing or of similar technologies, for example: In a turbo-compound engine the exhaust gas from the cylinders passes through a turbine, the two stages being dissimilar. In a compound steam locomotive the steam passes from the high pressure cylinder or cylinders to the low pressure cylinder or cylinders, the two stages being similar. In a triple expansion steam engine the steam passes through three successive cylinders of increasing size and decreasing pressure. Such engines were the most common marine engines in the golden age of steam.These examples and compound turbines are the main but not the only uses of compounding in engines, see below."@en }
