Variable Compression Ratio Two-Stroke Engine

SAE Technical Paper Series, 1989
<div class="htmlview paragraph">In Two Stroke Spark Ignition engines the thermal efficiency increases with increase in compression ratio. Also, with higher compression ratios the Ican burning limit increases because of the reduction in initial combustion period.

The Two-stroke Engine

1972
The basic two-stroke cycle was described in Chapter 1 and the operation of this type of engine can now be amplified. Fig. 12.1 shows a typical indicator diagram for a two-stroke, and it can be seen that because the ports open during the stroke the compression and expansion phases are restricted.

TWO Stroke Engines - The Lotus Approach

SAE Technical Paper Series, 1992
<div class="htmlview paragraph">The recent interest in two-stroke engines for automotive use has produced powerplants of such divergence that as yet, no clear outlook on a likely design is evident. The only common similarity between all the published engines is direct fuel injection.

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.

Development of Two Stroke Engines With Direct Injection

SAE Technical Paper Series, 1995
<div class="htmlview paragraph">In order to develop modern two-stroke engines with low fuel consumption, respectively with low exhaust emissions, two alternative development areas - the mixture formation and the scavenging system - have been correlated.

Hydrogen injection in two-stroke reciprocating gas engines

International Journal of Hydrogen Energy, 1983
Abstract A research study in the field of hydrogen-fed engines aims to obtain sufficient maximum power and to avoid any combustion anomaly which might prevent the engine from operating in normal conditions. Thus to investigate the direct injection of hydrogen into the cylinder, with the aim of better combustion with subsequent higher specific outputs,

Turbocharged Two-Stroke-Cycle Gas Engines

Journal of Engineering for Power, 1965
Pulse turbocharging, which had a long history of successful operation in sea-level installations on two-stroke-cycle gas engines, did not give satisfactory results at high altitude as evidenced by increased thermal loading and reduced load-carrying ability. Proper application of the constant-pressure system overcame these difficulties.

Development of Catalysts for Two-Stroke Engines

SAE Technical Paper Series, 1999
<div class="htmlview paragraph">The Emission Regulations for Motorcycles in Japan was put into effect in October 1998 with the goal of reducing the total hydrocarbon emissions from motorcycles in the country to around 50% of the present amount.</div> <div class="htmlview paragraph">These regulations initiated a need to develop ...

Exhaust Systems of Two-Stroke Engines

Proceedings of the Institution of Mechanical Engineers, 1938
Crankcase-scavenge two-stroke engines have always been fitted with a large expansion chamber immediately outside the exhaust ports, but this is by no means essential, as such engines will operate very satisfactorily with a plain exhaust pipe. The length of this pipe is most important and has a controlling influence on the scavenging of the cylinder ...

Features of an Atkinson Two-Stroke Engine

SAE Technical Paper Series, 1994
<div class="htmlview paragraph">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 ...
