Co2 Tracing Method for Measuring Raw Exhaust Gas Flow Rate at Exit From an Internal Combusting Engine for a Motor Vehicle and Measuring Equipment for Carrying Out Said Method

摘要

The invention relates to an CO₂ tracing method for measuring a raw exhaust gas ( 3 ) flow rate at exit from an internal combustion engine ( 1 A) for a motor vehicle ( 1 ). The inventive CO₂ tracing method for measuring raw exhaust gas flow rate at exit from an internal combustion engine for a motor vehicle consists, prior to starting the motor vehicle internal combustion engine, in injecting a known flow rate of a gas CO₂ and N₂ mixture into a metering line ( 20 ) in such a way that a raw CO₂ analyser ( 22 ) and a diluted CO₂ analyser ( 24 ) are triggered.
