Catalysts of a gasoline engine become active when the exhaust temperature exceeds 200 degrees C. Cold start HCs are extremely high until catalysts reach the light-off temperature. Determination of optimum place necessary ...

This paper reports an experimental study of tribological characteristics of cylinder liner (CL)/piston ring (PR) pair. Reciprocating wear process parameters are optimized for minimum weight loss and friction based on mixed ...

In this study, a steady-state thermal analysis was performed to evaluate the temperature gradients in the standard and two different partially stabilized ceramic coated pistons by using Abaqus (c) finite element (FE) ...
