Time was when a valve job was done with some valve-grinding compound and a vacuum cup on a stick. But no more. Today's high performance engines require the same machining precision in the valves that ...

The continuous drive for enhanced efficiency and reliability in modern diesel engines has prompted extensive research into the thermal management of critical components such as pistons. The ...

The vapor-compression cycle has four stages (compression, condensation, expansion, and evaporation) and one ultimate goal: converting refrigerant into a state that makes it useful as a heat transfer ...

To keep the piston from melting down, heat must be transferred out through the piston rings to the cylinder walls and ultimately into the cooling jacket. Today's engines tend to run hotter than ...

Two-dimensional computations of premixedcharge engine combustion were made using the KIVA-II code. The purpose of the study was to assess the influence of heat transfer and turbulence model boundary ...
