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 ...
