NOx Reduction
EPA emission mandates taking effect in 2010 require the reduction of nitrogen oxides (NOx) to .2 grams per brake horsepower (g/bhp). To meet this limit, engine manufacturers will use either selective catalytic reduction (SCR), NOx adsorber or advanced exhaust gas recirculation (EGR).
Most over-the-road truck and tractor manufacturers will use SCR technology, with International the only major manufacturer to use high EGR technology. Neither system is expected to increase fuel dilution. Light-duty diesel pickup manufacturers Ford and GM also will use SCR technology in their 2011 model-year trucks. Dodge plans to employ SCR technology in its medium-duty chassis cabs but plans to continue use of its NOx adsorber technology in the company’s light duty pickups.
Although AMSOIL Synthetic Diesel Oils
have shown the ability to maintain integrity under fuel-dilution conditions, the abnormally high rate and unknown long-term effects have forced AMSOIL to adjust its drain interval recommendations back to the manufacturer-recommended drain.
