RISPredicting Gas Leakage in the Rotary Engine—Part II: Side Seals and Summary
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Wankel rotary engine offers a greater power density than piston engines, but higher fuel consumption and hydrocarbon emissions, in large part due to poor gas sealing. This paper presents a model for the deformable ...
Predicting Gas Leakage in the Rotary Engine—Part I: Apex and Corner Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Wankel rotary engine offers a greater power density than piston engines, but higher fuel consumption and higher hydrocarbon emissions, in large part due to poor gas sealing. This paper presents a modeling approach to ...
Experimental Analysis of Chromium Molybdenum Coatings Under Mixed Elastohydrodynamic Lubrication for Film Thickness, Friction, and Wear Characterizations
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: This research aims to evaluate the tribological performance of chromium molybdenum (CrMo) coatings under point and line-contact mixed elastohydrodynamic lubrication. This article studies the coatings made from two different ...
Housing Profile Design for Improved Apex Seal Lubrication Using a Finite Length Roller Elastohydrodynamic Lubrication Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Finite-length roller contacts are found in apex seal-housing interfaces in rotary engines, as well as in many other mechanical systems, such as those at the interfaces of meshing gear teeth, cam followers, and roller ...
A Thermal Elastohydrodynamic Lubrication Model for Crowned Rollers and Its Application on Apex Seal–Housing Interfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a thermal elastohydrodynamic lubrication (EHL) model for analyzing crowned roller lubrication performances under the influence of frictional heating. In this thermal EHL model, the Reynolds equation is ...
