摘要

In order to estimate the combustion process from the rate of heat release in two-stroke slow-speed diesel engines with side fuel injection type for marine use, it is necessary to grasp characteristics of the rate of heat release data under various engine conditions. Systematic measurements were carried out on assignment of the experiment design method with four parameters using a test engine. As a result, the characteristics of the three important values in the rate of heat release: combustion period, peak height, and period up to the peak could be obtained, depending upon mean effective pressure, engine speed and the four control parameters of engine performance. In particular, it was found that the peak in height does not change with increasing mean effective pressure over a certain level and double peaks can be seen under some fuel injecting conditions.
