Pulse-Jet Engine Measurement of the Air-Fuel Ratio

Abstract

For internal-combustion engines where steady flow exists in the exhaust system, the air-fuel ratio may be determined by calculations based in the chemical analysis of the products of combustion. However, the exhaust process in the pulse-jet engine is an intermittent and pulsating one; consequently, the question arises whether or not the air-fuel ratio can be determined by the above method. This report presents data which show that the air-fuel ratio for the pulsejet engine may be determined by the chemical analysis for the amount of carbon dioxide, free oxygen, and carbon monoxide in the exhaust gases, provided that engine operation is steady and that the samples are drawn from a position between the forward part of the tailpipe inflow and the initial combustion zone.
