Tribological parameters such as friction, lubrication and wear influence strongly the engine component's life. In this study, a piston ring-cylinder system simulated taking into account the surface modifications under fully flooded lubrication and normal engine conditions. The hydrodynamic pressure field solved based on the Navier Stokes equations by Fluid Structure Interaction analysis. A real...

reactivity controlled compression ignition (rcci) is a novel combustion concept which uses port fuel injection (pfi) of a low reactivity fuel and direct injection (di) of a high reactivity fuel with optimum multiple injection to provide a stratified mixture inside the combustion chamber. piston bowl design has a considerable effect on engine’s pollutant emissions specially unburned hydrocarbons...

This study deals with the frictional power of each moving part in hydrogen fueled multi-cylinder spark ignition engine. The parts such as piston, rings, bearings, cam, and roller follower are considered for this study. engine was run at a constant speed 1500 rpm different loads. indicated is calculated using in-cylinder pressure data, brake measured respect to component calcu-lated models avail...

This paper presents the results of testing a wear-resistant ceramic coating on work surface an internal combustion engine (ICE) cylinder’s sleeve. A combined formation technology is described that consists in applying aluminum layer to sleeve’s face by gas dynamic spraying and then covering this with microarc oxidation (MAO). tenfold reduction reinforced sleeve has been determined accelerated c...

A finite element model is developed to assess the effects of TiSiCN thin film coating piston ring on structural strength subsystem. The complex, cyclically variable forces are considered in load and boundary conditions. included combustion dynamics, contact kinetics, subsystem primary secondary motions, lubricated conditions evaluate applied forces. comparative analysis performed for coated unc...
