The Estimation of Part-Load Performance of Turbocharged Two-Cycle Diesel Engine

Abstract

The preceding papers have set out the calculations of the performance of turbocharged two-cycle Diesel engines on the basis of given values of the variable parameters. These are the kind of calculations which must be carried out in order to estimate the performance at the design point of an engine. In gas turbines, the part load performance can be estimated by linking together in correct manner the performance of several components, most of whose characteristics cannot be expressed mathematically. In this paper, we attempt to estimate the part-load performance of turbocharged two-cycle Diesel engines by the same process, replacing the combustor of a simple gas turbine with the Diesel cylinders. At the same sime, the influences of changes in the assumed component performance features on the part-load performance of an engine are found out by this method.
