Investigation of Diesel-Powered Vehicle Emissions. Part VIII. Removal of Exhaust Particulate from Mercedes 300D Diesel Car.

摘要

The objective of the project was to investigate the potentialities of reducing the particulate exhausted from diesel-powered passenger cars by the use of available lead trap technology. The particulate exhausted from diesels is one of several currently non-regulated emissions that is of concern,especially if the anticipated growth in diesel cars occurs. A system including front and rear agglomerator devices,packed with alumina coated steel wool,and an inertial separator,were mounted in place of the usual front resonator and rear muffler. When relatively new,the system was found to be effective on particulates and also reduced exhaust hydrocarbons,odor,smoke,benzo (a) pyrene,and sulfate. Acceleration performance suffered due to increased backpressure from the system. The life of the system is relatively short,less than 5000km.
