High Speed Gas Sampling System for Engine Cylinder Emission Analyses

Abstract—In this study, high speed gas sampling system was used to collect gas samples in the engine cylinder. C1-C5 based HC components behaviuor in the engine cylinder were investigated experimentally during the flame period. Model GSD-10 fast response gas sampling system was used to sample gas in the cylinder. The high speed gas sampling valve mounted on the engine cylinder was connected to the gas chromatograph instrument directly, and samplings were continuously gathered at the intended crank shaft angle ranges. The electro-magnetic valve lift time was controlled by setting a time-lag from the TDC reference point of the engine crank angle. Crank pulses were provided by crank pulse generator. The generator consists of a slit disc mounted on the engine shaft and a photo-electric pick-up. It was designed to generate the crank pulse (360 pulses/rev) and the reference pulse (1 pulse/rev). In cylinder gas samples were taken for 10-15 degree intervals after the ignition. Samples taken during the flame period were approximately 60 degrees of crank angle after the spark plug ignited. In this study, Agilent 7890A Gas Chromatography (GC) system was employed to analyze C1-C5 HC component of the sampled gas from the engine cylinder. GC-FID (Flame Ionization Detector) analysis method was utilized to investigate hydrocarbon components. Response time of hydrocarbon components were listed. HC components variation with respect to crank angle were plotted and interpreted.

Index Terms—Gas sampling system, in cylinder engine emissions, hc components.
