抄録

Combusting sprays which impinge upon the wall of a constant volume combustion chamber were achieved in a rapid compression machine to examine the effects of injection pressure and ambient density on the heat rejection to the chamber wall. The real heat release, Q_s, was determined by the exhaust gas analysis and the apparent heat release, Q_a, was calculated using cylinder pressure time histories. The heat rejection or heat loss fraction was defined as (Q_s-Q_a)/Q_s, and its variation with operating parameters was discussed. It was shown that the heat rejection decreases as the ambient density and the injection pressure increase, but tends to increase with the fuel injection amount. These trends were understood as the results of the balance among the effects of the heat transfer coefficient, the cylinder gas temperature, and the combustion duration, which are affected by the experimental conditions.
