Diesel Fuel Additives to Reduce NOx Emissions from Diesel Engines Operated on Diesel and Biodiesel Fuels by SNCR

Diesel engines are expected to remain in use for high power applications even with the rising fuel prices and environmental concern and the new laws imposed by government to reduce emissions. Unfortunately, diesel engines possess a bad reputation of producing higher PM and NOx emissions compared to gasoline engines. The present work describes the use of different additives to diesel or biodiesel fuel to reduce NOx emissions up to 22 % from the diesel and up to 47 % from the biodiesel fuels. This study is a preliminary investigation of the successful reduction of NO x emissions from diesel and from biodiesel fuels and forwards a strong argument that SNCR could reduce the NO x emissions from diesel engines in an efficient way when proper compounds are chosen to do the work.
