Experimental study of the impact of scavenging efficiency on diesel combustion in an opposed-piston two-stroke engine

International Journal of Engine Research, 2022
The opposed-piston two-stroke (OP2S) engine is a promising alternative powertrain technology that can offer thermal and brake efficiency improvements over conventional four-stroke engines.

Experimental Comparison of Diesel and Wet Ethanol on an Opposed-Piston Two Stroke (OP2S) Engine

SAE technical paper series, 2023
Renewable fuels, such as the alcohols, ammonia, and hydrogen, have a high autoignition resistance. Therefore, to enable these fuels in compression ignition, some modifications to existing engine architectures is required, including increasing compression

Features of an Atkinson Two-Stroke Engine

SAE Technical Paper Series, 1994
A two-stroke Atkinson cycle engine is described. The engine has uniflow stratified mixture scavenging with a variably phased spherical rotary valve in the cylinder head and exhaust ports in the cylinder wall. These features combined in this configuration result in reduced fuel consumption, higher specific power output, less vibration, and smooth part ...

Scavenging the two-stroke engine

Progress in Energy and Combustion Science, 1990
Abstract The scavenging process is the most important factor controlling the efficiency and performance characteristics of a two-stroke-cycle engine. This article reviews and assesses experimental and theoretical methods, which have been applied during the past three decades, to evaluate the success of the scavenging process.

Powering a two-stroke RNA engine

Nature Structural & Molecular Biology, 2007
The spliceosome, the ribonucleoprotein complex that removes introns from precursor messenger RNAs, is thought to undergo conformational changes between two alternative states to catalyze the two steps of the splicing reaction, a model that resembles ribosomal transfer RNA decoding.
