The Laser Doppler Anemometer, a new instrument capable of making non-interfering gas velocity measurements, has been used to investigate the gas behavior in the cylinder of a firing engine. First of all, the necessary conditions for a real-time measurement of the gas velocity by the LDA are examined, and thereby two typical flow, squish and torch, in the cylinder of an engine with both motoring and firing have been measured. As a result, the optical technique is ascertained to be a promising one for application to research on a firing engine.
