Navistor is the exception. The company is using advanced exhaust gas recirculation in its MaxxForce engines. The in-cylinder technology will require no additives to meet 2010 requirements.
Several of the engines makers took part in two panel discussions recently at the Great American Trucking Show in Dallas.
