Two-Stroke Wankel Type Rotary Engine: A New Approach for Higher Power Density
Energies, 2019 The Wankel engine is a rotary type of four-stroke cycle internal combustion engine. The higher specific power output is one of its strong advantages. In Wankel rotary engine, every eccentric shaft revolution corresponds to one four-stroke cycle, whereas ...

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 ...

6-Stroke Engine: Thermodynamic Modelling and Design for Testing
Journal of KONES Powertrain and Transport, 2019 In the study AVL BOOST™ is used to perform a thermodynamic simulation of a six-stroke engine, being built by a research team based in Saudi Arabia. The six-stroke cycle consists of a standard four-stroke Otto Cycle followed by a heat recovering steam ...
