Tribopolymerization as an approach to two-stroke engine lubrication
… performed to investigate the current status of two-cycle gasoline engines from the standpoint of design, performance, benefits, lubrication and emissions. The two-stroke engine offers several significant advantages over its four-stroke counterpart, which include: simple design, low production …

Development of an efficient 3-D CFD software to simulate and visualize the scavenging of a two-stroke engine
The two-stroke engine is widely used in many different devices. But the environmentally problematic exhaust characteristic is a big drawback of this type of engine. In the scavenging process, when the fresh charge displaces the exhaust gas in the cylinder, lies the biggest opportunity to improve …

Modelling the scavenging process in a two-stroke I.C. engine
The primary concern associated with a two-stroke engine performance is its gas exchange process (scavenging process). The success of the scavenging process greatly affects the thermodynamic properties of cylinder content at the trapping conditions and hence the combustion and power output. The …

Two-stroke linear engine
Linear, crankless, internal combustion engines may find application in the generation of electrical power without the need to convert linear to rotary motion. The elimination of the connecting rod and crankshaft can improve the efficiency of the engine significantly and the reduced weight and cost …

Real-time non-intrusive reed valve measurement and analysis
… the real-time behaviour of reed valves in a two-stroke engine. This sensor has allowed the acquisition of high resolution position data, recorded during unstable operating conditions, in a format that is convenient for further analysis. This in turn has provided the opportunity to improve the …

Understanding HCCI characteristics in mini-HCCI engines
… in a standard issue model-aero “diesel” engine. This two-stroke engine, unlike the more common glow-plug versions, operates without any form of combustion initiator. The fuel and air are premixed using a simple carburettor and ignited by piston compression only. The engine therefore …

Hybrid Electric Distributed Propulsion for Vertical Takeoff and Landing Aircraft
… begins by characterizing the performance of two similar embedded propulsion systems using computational fluid dynamics (CFD). From this initial analysis, a wind tunnel model is constructed and the systems are tested across the operating conditions required to characterize the performance of a …
