Paper 5: Electronics Applied to Medium-Speed Engines

Abstract

The use of electronic recording equipment now covers development, production, and service problems. Previously fuel injection characteristics and gas exchange pressures were the only parameters normally indicated. Today, however, owing to the demand for greater power outputs, a much wider range of parameters are studied electronically. The success of engine development and production relies upon the ease and accuracy with which engine performance can be measured. The historical development of engine indicating techniques used by the authors' company and the existing measuring accuracies are discussed. Various tables outline the individual and overall errors that were obtained using a wide range of transducers and associated equipment. The need for correct calibration procedures is emphasized throughout, and some of these procedures with their standardizing equipment are included in the paper.
