- Summary:
- In order to achieve the emission levels required for Low Emission Vehicles (LEV) and Ultra Low Emission Vehicles (ULEV) it is necessary to obtain insight into emission reactions to the motor management systems during transient engine performance. The optimisation of transients in typical driving profiles, such as shifting, acceleration load reversal, necessitates suitable gas measurement equipment.A technique capable to resolve one combustion cycle consists in spectroscopic gas analysis by using tunable infrared diode lasers. This paper describes the available equipment and demonstrates that a diode laser system fulfils the specific demands for the analysis of transient operating characteristics of engine management systems
