MECA study shows technologies can fix non-road diesel emissions problems

Diesel Fuel News, April 23, 2003

Manufacturers of Emission Control Association (MECA) released a new study showing how diesel particulate filters (DPFs) and catalysts for nitrogen oxides (NOx) control can be employed on a wide variety of non-road diesel engines. The <75 hp engines will "present special challenges" for ultra-low PM/NOx control, so they'll need advanced fueling systems similar to those of on-highway engines, MECA explains.

These systems will allow modulation between lean and rich operation, required for NOx trap operation. Some DPF's also can be regenerated off-line or on-line with electrical burners, as in tens of thousands of forklifts. Meantime, over 250,000 non-road vehicles already have "passive" diesel oxidation catalysts in the world today, including minimg vehicles, skid-steer loaders, forklifts, construction vehicles and stationary engines, MECA points out.
