REDUCING NOx EMISSIONS FROM AN ENGINE BY TEMPERATURE-CONTROLLED UREA INJECTION

A safe, reliable SCR system for reducing NOx emissions from a lean-burn internal combustion engine utilizes urea in aqueous solution. Overheating and hydrolysis of the solution are prevented by maintaining the temperature of the urea solution sufficiently low that it is not permitted sufficient time...
