DIESEL PARTICULATE TRAPS

This volume brings together the papers presented in the 1984 SAE Annual Congress on the subject of control of particulate emissions from diesel engine exhaust. The work reported here focuses in some part in trap oxidizer development and its implication for vehicular applications. In the past year, there has been significant progress and change in many aspects of this problem. Some of the important factors are that: technology of regeneration has advanced, public awareness of the environmental problem has increased, government regulation remains firm and threatens to expand, and the market share of diesel vehicles has changed considerably. The trap oxidizer appears in various shapes and designs but it is basically a filter combined with some means of removal of the accumulated particulate matter by burning (regeneration). Not long ago it was strictly a laboratory device, but now has progressed to the point where successful 50,000 mile vehicle durability tests with it are more than a rare event. The real test of its success will be in vehicles in the hands of the driving public. The coming year will see the first production application of this device appearing in passenger cars designed to meet the .4 GM particulate standard in 1985 model year in California. A good deal of time in this conference is devoted to the task of particulate control of the various classes of heavy duty vehicles. The work reported here describes the progress made particularly in the area of urban buses and explains the uniqueness of the problem with this type of vehicle. The conclusions from it will have important implications on regulatory policy. Finally, the costs and benefits of particulate control are once again analyzed. They conclude the benefits are clearly in excess of the costs and that, depending upon overall sales levels, truck controls may be as important as those on passenger cars.
