Navistar International's not beating 'em, so it looks like it's going to join 'em. The truckmaker, which has been pushing its exhaust-gas recirculation process as a cheaper, simpler emissions-treatment method than the selective catalytic reduction method used by its competitors, will likely switch to SCR to better appease the Environmental Protection Agency, the Wall Street Journal reported, citing people familiar with the process that weren't identified.
Thomas Built Buses, the school bus manufacturing unit of Daimler Trucks North America, has just received its first order for new clean diesel buses. Montgomery County in Maryland has ordered 59 new Saf-T-Liner HDX school buses equipped with selective catalytic reduction (SCR) systems. The SCR system eliminates most nitrogen oxide emissions and allow the buses to meet the 2010 emissions standards for heavier trucks.
Just as a whole batch of new fifty state-legal diesel vehicles are about to hit the market in the U.S., chemical company BASF is set to take advantage of the situation. BASF has announced that they will be raising the price of AdBlue by €45 per 1,000 liters. AdBlue is the 1/3 urea, 2/3 water solution used for the NOx after-treatment system in new diesel engines. The urea solution is injected into the exhaust gas stream where the heat of the exhaust causes it turn into ammonia by a hydrolysi
Most people probably don't know the name PACCAR but they've surely seen Peterbilt, Kenworth and DAF. Those are three of the biggest medium and heavy duty truck brands on the market . The smoky exhaust from those big diesel trucks has surely annoyed most drivers and pedestrians at some point in time. PACCAR produces trucks under those brands and others that are used around the world. The company has announced plans to meet 2010 diesel emissions requirements by adding exhaust gas recirculation (EG
The Environmental Protection Agency is considering a variety of rules that it might apply to urea injection for diesel engines, and is said to ready to issue rules for such emission-control devices in upcoming weeks. The regulations are expected to address potential issues arising with urea injection, such as the availability of the substance, making sure that the system and its low-fluid-level warning system are tamperproof, and dealing with urea's freezing point of 11F.
