Kicking the can: Engine OEMs shed weight, optimize fuel economy with after treatment system redesign
Few things in trucking draw more scrutiny and scorn than a diesel engine’s after treatment system. The adjustment from pre-Selective Catalytic Reduction (SCR) engines to the modern clean diesel era ...
LOUISVILLE. At the Mid-America Trucking Show yesterday, Volvo Trucks North America announced that its 2010 highway trucks equipped with SCR (selective catalytic reduction) emissions control systems ...
We appear to be learning from our mistakes in aftertreatment system maintenance, but we still have a way to go before we’re at peace with the things. Strictly speaking, diesel particulate filters, ...
Single Module aftertreatment system combines the Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) systems into a single canister. The Cummins ...
The diesel engine has undergone a significant evolution over the past two decades. Most of these changes were designed to reduce emissions and air pollution, but once early generation emission goals ...
