SAMPLER FOR ENGINE EXHAUST DILUTION |
摘要 |
<p>A partial flow sampling system includes a system inlet for receiving an exhaust sample flow from a sample inlet probe and transfer line. The system further includes a dilution air control system for controlling a dilution air flow rate, and a mixer. The mixer receives and mixes the exhaust sample flow and the dilution air flow to produce a mixture flow. A total flow control system controls the mixture flow rate. An orifice flow meter installed at the system inlet measures the exhaust sample flow rate in real-time. This provides accurate sample flow measurements over a wide range of dilution ratios and sample ratios.</p> |
