Single-cylinder 125 cc Stepped-piston Engine for Mobility and Portable Power Generation Applications
International Journal of Technology, 2016 Two-stroke engines are far simpler than four-stroke engines from a physical perspective. For a given brake output, two-stroke engines are lighter, easier to work on, and provide higher power-to-weight ratio than four-stroke engines, making them ...

SIX STROKE ENGINE ARRANGEMENT [PDF]
The International Conference on Applied Mechanics and Mechanical Engineering, 2012 In six stroke engine, there are additional two strokes, namely another power and exhaust strokes. The engine works through harnessing wasted heat energy created by the fuel combustion. After the combustion stage water is injected into the super- heated cylinder. The water explodes into steam and force the piston down.
