Exhaust Particulate

BS 6680 requires the efficiency of coalmine diesel engine exhaust pollution-reduction devices to be determined. The efficiency of an Englehard PTX catalyst and water scubber for both particulate and gaseous emissions reduction was determined using a 533 cc single-cylinder Petter AVI direct injection diesel engine. The separate and combined influence of the two exhaust devices was determined. The water scrubber acted as aflame trap as well as an exhaust particulate trap. The catalyst gave a substantial reduction in CO and UHC gaseous emissions and particulate SOF emissions for exhaust temperatures above 250°C. However, the high MW particulate SOF, including the PAH, had a 70 per cent reduction for catalyst temperatures as low as 200°C. The water scrubber was the dominant particulate removal device, although the catalyst removal efficiency was significant for temperatures above 250° C. The scrubber also had a significant influence on the reduction in NOx emissions, with a 30 per cent removal at high exhaust temperatures.

This paper presents the results of SNAME Small Craft Panel SC-3 Fishing Systems investigation of trends in US fishing vessel (Fig. 1) (L> 22.9 m) powering and NOx emissions (1900–2000). The study estimates the 1, 299 vessels in the US fishing fleet produce 306 tons/day of NOx. The largest powers are found in the decades of 1960–1980. The actual power kW is compared to a reference power kWo using the Powering Index Ratio PIR = kW/kWo. It was found that 50 to 80% of the power in seiners, trawlers, and crabber/ trapper/clam vessels have PIR > 2.5. The reduction of fishing vessel diesel engine NOx can be best achieved by adopting acceptable levels of vessel power/length for the basis of revenue and tax rather than using the vessel age as emissions reduction criteria.

Abstract This research investigates engine performance and the potential of reducing exhaust emissions by using Dimethyl Ether (DME) which is an alternative fuel for diesel engines. The objective of this study it to evaluate (on the bed test) the performance and emissions reduction potential of an engine running with DME. A 4 cylinder passenger car HSDI Common Rail turbocharged diesel engine without specific modifications was used. The results obtained on this engine running with DME using diesel fuel as reference are encouraging. In the next steps of this study the injection rate will be adapted to DME operation and to the geometric and thermodynamic conditions of the combustion reaction. A study of the combustion reaction is also necessary in order to optimize the turbocharging system to exclusive DME operation.
