The first report proposed a new heat transfer coefficient formula applicable to diesel combustion. This, the second report, incorporates this formula into a heat loss prediction model and evaluates the prediction accuracy of heat loss over the whole engine operation range by using a diesel combustion simulation (UniDES: Universal Diesel Engine Simulator). In addition, the proposed model also factors in the effect of lower spray penetration due to swirl flow. As a result, it was clarified that prediction accuracy improved in every engine operation region, and it was possible to predict the indicated mean effective pressure with an accuracy containing an absolute error of less than 2.3%.
