Some studies on the instrumentation of a single cylinder, spark ignition engine

Abstract

A project was undertaken to study the air metering and cylinder pressure measuring components of an instrumentation system for a single cylinder spark ignition demonstration engine. The overall problem of the selection of an instrumentation system for such an engine is briefly discussed. Details of a torque measuring system are included together with a brief review of the current methods for measuring air consumption and engine cylinder pressure. Reasons for selecting the specific air metering and cylinder pressure indicating devices used in this project are presented.
