Title:

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

Document Type and Number:

WIPO Patent Application WO2006103368

Kind Code:

A3

Abstract:

The invention relates to an CO₂ tracing method for measuring a raw exhaust gas (3) flow rate at exit from an internal combustion engine (1A) 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.
