Here at Interstate Fleet Maintenance, our team of experts and state-of-the-art emissions testing technology will keep your vehicles in compliance of state and federal standards.
Selective catalytic reduction (SCR) technology is a proven and effective method to reduce nitrogen oxide (NOx) emissions from diesel engines.
During the combustion process, the nitrogen that is present naturally in the coal, and the nitrogen and oxygen present in the combustion air combine to form NOx. Prior to being released to the atmosphere, the exhaust gas is passed through a large catalyst where the NOx reacts with the catalyst and ammonia and is converted to nitrogen and water. Selective catalytic reduction typically removes between 80 and 90% of the NOx that is in the exhaust gas of a diesel engine.
