With fuel economy, weight and cost being ever-important concerns, truck OEMs stay hard at work in developing fuel-efficient solutions while complying with the latest regulations. The new SCR, or selective catalytic reduction, technology to meet 2010 federal emissions standards will do just that. And, though it carries Continue Reading

For drivers of today’s new diesel-powered trucks, their maintenance routine will include upkeep of diesel particulate filters, as well as the selective catalytic reduction aftertreatment device. Both operators and technicians will be faced with learning the inner workings of both, though maintenance is said to be minimal. SCR systems need Continue Reading

A letter from a California Air Resources Board researcher is causing a stir in the debate over which technology is better all around for meeting 2010 federal diesel emission standards. According to CARB research, the selective catalytic reduction process most engines will employ could emit toxic byproducts with the introduction of Continue Reading

The debate over the better value in engine technology to meet 2010 federal emissions standards – Advanced EGR vs. SCR – has in some ways become a war of words between the two truck manufacturers who released pricing. Volvo’s SCR, or selective catalytic reduction technology, will carry a Continue Reading

The only truck maker that won’t be using selective catalytic reduction (SCR) technology to meet 2010 federal emission requirements will wrap up its final validation phase testing this summer. Navistar, which instead will use exhaust gas recirculation engine technology, said its recent tests included cold-weather testing in northern Continue Reading

A composite heavy-duty air cleaner available from Racor is ideal for gasoline and diesel powered equipment used in high dust environments. Durable enough to withstand excessive vibration and extreme temperatures, the air cleaner is lightweight and offers Continue Reading
