LEAN MIXTURE ENGINES TESTING AND EVALUATION PROGRAM. VOLUME III: APPENDICES
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 appendices presents supplemental analysis methods, fuel economy and emissions test data, and a description of the instrumentation used in the testing and evaluation program.
