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 …

Étude numérique et expérimentale du comportement non linéaire des plaques perforées en présence d’écoulement
Cette thèse étudie expérimentalement la réponse acoustique de plaques macro-perforées (pourcentage de surface ouverte (POA) jusqu’à 40% et diamètre jusqu’à 3 mm), en présence d’un écoulement rasant et soumis à des niveaux de pression acoustique (SPL) élevés jusqu’à 180 dB. Tout d’abord, une méthode …
