    Gas monitoring instruments and systems for engine emissions measurements

    The exhaust gas from combustion engines is a complex mixture of gases and particulate matter. The composition of the gas may change rapidly. Multicomponent analysis of exhaust gases can be performed with a Gasmet™ FTIR Gas Analyzer with a response time (T90) of one second. The winning combination is the result using of a small volume gas sample cell, a powerful sample pump and a fast detector with liquid nitrogen cooling. The analyzer, sampling system and computer can be assembled on a cart for use in a dynamometer laboratory, or the portable version can be used for roadside tests.

  • Emissions testing for engines

    Rich-burn engine exhaust, when uncontrolled, can have wide concentration ranges and both CO and NOX can fluctuate significantly. The on-board CO dilution system will automatically set-up for optimum testing, perfect for a rich burn engine. Lean-burn engines have different exhaust characteristics, but NO2 can make up a significant portion of the total NOX measurement. The 350 measures both NO and NO2 for proper lean-burn engine set-up. Due to high concentration, replaceable interference filters keep the sensors stable and your readings accurate. High exhaust pressures and heavy particulate loading are easily controlled with the special pressure relief valve (standard) on the engine probe configuration.

    PTR-TOFMS systems for automotive real-time vehicle exhaust analysis

    Monitoring exhaust gas from combustion engines, emitting a large number of different compounds and with rapidly changing concentrations due to variations in operating conditions, necessitates an instrument that measures in real-time and with high sensitivity – an IONICON PTR-TOFMS.
