Abstract:

This report is aimed at defining analytically and demonstrating experimentally the potential of the 'lean-burn concept'. Fuel consumption and emissions data are obtained on the engine dynamometer for the baseline engine, and two lean-burn configurations of the same engine and data comparisons are made. Individual cylinder equivalence ratios are measured to evaluate the cylinder-to-cylinder distribution. Pressure-time traces from individual cylinders are used to get information about ignition delay, combustion duration and cycle-to-cycle pressure variations. Fuel consumption and emissions data for one lean-burn configuration are obtained over the Federal Driving Cycle using a chassis dynamometer and the results are compared with the stock baseline results. Using experimental results and information from the existing literature, the potential of the 'lean-burn concept' is assessed using the Blumberg-Kummer cycle analysis program. The report consists of three volumes. Volume I, the Executive Summary, presents a summary of the experimental equipment and procedure, together with the experimental results and conclusions.
