The design of an apparatus to determine the film coefficient of water at high heat fluxes
… discharge end of the test section through the exhaust valves. The fluid leaving the test section is condensed and sub-cooled by a vertical vapor-in-tube type heat exchanger so that the fluid can be recirculated again. An auxiliary ion-exchanger system is provided for deionization of the test …

The mechanics of valve cooling in internal-combustion engines. Investigation into the effect of VSI on the heat flow from valves towards the cooling jacket.
Controlling the temperature of the exhaust valves is paramount for proper functioning of engines and for the long lifespan of valve train components. The majority of the heat outflow from the valve takes place along the valve-seat-cylinder head-coolant thermal path which is significantly influenced …

Analysis of parasitic losses in heavy duty diesel engines
… piston, mass flow rates through the intake and exhaust valves, heat release during combustion, and heat transfer rates. The results demonstrate the potential to decrease power cylinder between 15% and 30% depending on coating thickness and application zone. This corresponds to approximately a …

Particulate matter emissions from a DISI engine under cold-fast-idle conditions for ethanol-gasoline blends
… (PN) concentration 15 cm downstream from the exhaust valves of a DISI engine, for a temperature range between 0 and 40"C, under low load operation. Seven gasohol fuels have been tested with the ethanol content varying from 0% (EO) up to 85% (E85). For E10 to E85, PN modestly increases when the …
