Diesel Engined, Light Duty Vehicles for an Emission Controlled Environment 790761

The diesel engined light duty vehicle shows a substantial improvement in fuel economy over its gasoline engined counterpart. It will however have very great difficulty in meeting proposed gaseous and particulate exhaust emission levels.
The interactions between fuel economy, NOx emissions, and exhaust particulate emissions as demonstrated by an extensive series of tests on a Mercedes Benz 300D car with modulated exhaust gas recirculation are correlated with published data from other diesel engined vehicles to predict levels which could be achieved with current technology and to estimate the fuel economy penalties.
