Diesel Technology

As Durable As It Is Powerful

The first Chrysler LLC vehicles to meet the stringent U.S. 2010 truck emissions standards are the 2007 Dodge Ram 2500 and 3500 Heavy Duty pickups.

The 6.7-litre Cummins^® turbodiesel I-6 engine makes our new trucks significantly cleaner than other pickup trucks.

Although today's diesel engines are extremely advanced, diesels are not a new technology. In 1892, Rudolf Diesel obtained the German patent for diesel engines. Gasoline engines of that time were very inefficient and Rudolf intended to produce a more economical combustion engine. Today's advanced diesels are among the most efficient combustion engines.

The 2007 Dodge Ram Heavy Duty engine uses a diesel particulate filter (DPF) to greatly reduce particulate matter emissions and an adsorber catalyst to reduce oxides of nitrogen (NOx) by as much as 90 percent.

A cooled exhaust gas recirculation (EGR) system combined with a uniquely designed piston combustion bowl and a high-flow, electronically-controlled Variable Geometry Turbocharger matches boost pressure with the engine's performance needs to reduce emissions and improve drivability.

The emissions system is designed for a U.S. government-certified 193,000 kilometres (120,000 miles).
