WHITE PAPER: Meeting Tighter Emissions Limits While Improving Diesel Engine Efficiency
Summary
New environmental legislation has created an engineering challenge for heavy-duty diesel engines.CO2 and NOx emissions must fall below stricter standards; at the same time greater engine efficiency has resulted in a corresponding loss of exhaust gas temperature, leading to lower catalytic activity. This is particularly concerning when it comes to NOx emissions for Cold Start and Low Load Cycles, as there is a lot of thermal inertia in the aftertreatment system.
