Numerical analysis of a downsized 2-stroke uniflow engine [PDF]
Engine dowsizing is one of the most effective means to achieve the reduction in fuel consumption and CO2 emissions from passenger cars. All engine downsizing so far has been achieved through the replacement of a NA 4stroke engine with another 4-stroke ...

Turbocompounding the Opposed-Piston 2-Stroke Engine [PDF]
This paper presents analytical research conducted into the level of fuel consumption improvement that can be expected from turbocompounding a medium-duty opposed-piston 2-stroke engine, which is part of a hybridized vehicle propulsion system. It draws on a successful earlier study which showed a non-compounded opposed-piston engine to be clearly ...

CFD Analysis of 2-Stroke Engines [PDF]
Abstract1d and 3d CFD simulation is a standard engineering practice on 4-stroke engines. However, the application to the 2-Stroke cycle is not so trivial, in particular the transition from detailed CFD-3d analyses to simplified 1d engine simulations. A first critical issue is the correlation between the instantaneous cylinder gas composition and the ...

Development of a 2-Stroke GDI Engine [PDF]
Abstract Nowadays, high-pressure gasoline direct injection (GDI) can be considered a standard technology, due to the wide application on 4-stroke turbocharged engines. This technology – in combination with other specific solutions - has been successfully applied to a 500 cc, 30 kW 2-stroke engine, initially developed as a range extender.

A New Design Concept for 2-Stroke Aircraft Diesel Engines [PDF]
AbstractHigh power density, low weight, compact dimensions, high efficiency as well as reliability are the key factors in designing and dimensioning piston engines for General Aviation and Unmanned Aerial Vehicle (UAV) power plants. Despite of new available technologies, conventional solutions are still struggling to fulfill simultaneously all those ...

Access to post - stroke physical rehabilitation after acute reperfusion therapy– the neglected link in ischemic stroke management: a retrospective cohort study [PDF]
Background: The burden of stroke is high in Romania and data regarding access to post – stroke rehabilitation are almost non–existent. We aimed to determine the percentage of patients who benefited from post–stroke rehabilitation and to describe the most
