Exhaust Gas Sampling and Conditioning - DieselNet
WEBExhaust Gas Sampling and Conditioning. Heinz Burtscher, W. Addy Majewski. Abstract: Before emissions can be measured, gas has to be sampled from the exhaust system. In most cases, gas is sampled from diluted exhaust. Exhaust gas dilution can be performed either in a full flow dilution tunnel, such as the CVS system that is commonly used for ...
