The four-stroke reduction engine [PDF]
Proceedings of the 1986 ACM conference on LISP and functional programming - LFP '86, 1986 © 1986 ACM. Functional languages are widely claimed to be amenable to concurrent execution by multiple processors. This paper presents an algorithm for the parallel graph reduction of a functional program. The algorithm supports transparent management of parallel tasks vlth no explicit communication between processors.

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 ...

Conversion of four-stroke engines to six-stroke engines using epicyclic gearing in camshaft modification [PDF]
Mechanical SciencesIn this study, a compact, single-cylinder, spark-ignition, four-stroke engine commonly used in power generators is converted into a six-stroke engine. This conversion employed the free-stroke Kelem model, one of the six-stroke engine approaches described
