Abstract
This paper describes the design and operation of a sampling valve suitable for time resolved sampling of gases from the cylinder of an operating engine. A continuous flow of cylinder gas passes through the valve orifice. The valve diverts a small portion of this flow to a sample collection volume upon demand. The flow diversion is accomplished by action of an internal rotating sampling tube mechanism. The sampling period is 1 msec or less. The sampling system has been operated successfully in a fired Diesel engine for insertion depths of up to one-quarter inch.Keywords
