Novel Two-Stroke Engine Concept, Feasibility Study

SAE Technical Paper Series, 2003
<div class="htmlview paragraph">A novel two-stroke engine concept is introduced. The cylinder scavenging takes place during the upward motion of the piston. The gas exchange valves are similar to typical four-stroke valves, but the intake valves are smaller and lighter. The scavenging air pressure is remarkably higher than in present-day engines.

Endogenous regeneration: Engineering growth factors for stroke

Neurochemistry International, 2017
Despite the efforts in developing therapeutics for stroke, recombinant tissue plasminogen activator (rtPA) remains the only FDA approved drug for ischemic stroke. Regenerative medicine targeting endogenous growth factors has drawn much interest in the clinical field as it provides potential restoration for the damaged brain tissue without being limited

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.

Enzymatic production of rice bran biodiesel and testing of its diesel blends in a four-stroke CI engine

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2019
Due to the high prospective of rice bran oil, it can be used as a resource for biodiesel production. This study aims to produce high-quality rice bran biodiesel through enzymatic transesterification using lipase enzyme.

Total Engine Friction in Four Stroke S.I. Motorcycle Engine

SAE Technical Paper Series, 1988
<div class="htmlview paragraph">Many papers are written on the frictional loss of each component in an engine, such as piston, crankshaft or bearings, but few papers describe on the total engine friction in detail. In this paper, the total engine friction is analyzed using the engine friction data of 145 HONDA mass produced motorcycle in-line ...

The Two-Stroke Rotary Engine

SAE Technical Paper Series, 1998
<div class="htmlview paragraph">An innovative rotary engine uses a rotor that executes pendulum-like oscillatory rotation. This is converted into uniform rotation of the drive shaft by a simple mechanism. The engine also employs parameter resonance. The new design is compact and lightweight.

Lubrication analysis for the piston ring of a two-stroke marine diesel engine taking account of the oil supply

International Journal of Engine Research, 2019
The piston ring is one of the most important parts of a two-stroke marine diesel engine. It is lubricated by a special mode in which the lubricating oil is directly injected into the liner’s inner surface.

Two-stroke hydrogen injection engine

International Journal of Hydrogen Energy, 1979
Some of the advantages of the two-stroke hydrogen injection engine developed by Musashi Institute of Technology are given. Flashbacks never occur. Higher output than with a gasoline engine is obtainable because the amount of mixture is larger, since only air is introduced.

Two-Stroke S.I. Engine Competitive to Four-Stroke Engine in Terms of the Exhaust Emission

SAE Technical Paper Series, 1994
<div class="htmlview paragraph">A model engine with disintegrated working cycle was build. Its operation is not autonomous; compression of the working air is performed separately outside the engine by the compressed-air line supply. Pre-compressed charge together with the injected fuel is introduced in the combustion chamber.

Expansion Engine - 4 strokes

This work introduces a novel expansion engine that integrates heat exchange with thermal energy storage and operates on a Quasi-Carnot cycle, combining quasi-isothermal and quasi-adiabatic processes. Unlike conventional combustion, Stirling, or Organic Rankine systems, the proposed design minimizes entropy generation and improves efficiency by using ...
