Diesel Technology

Durable, Clean and Powerful

Thanks to the Cummins® 6.7-liter turbodiesel engine, the 2007 Dodge Ram 2500 and 3500 Heavy Duty pickups were the first Chrysler Group LLC vehicles to meet the stringent 2010 truck emissions standards in all 50 states. And the 2010 models continue to meet these standards. This 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.

How It Works

The 2010 Dodge Ram Heavy Duty engine uses a diesel particulate filter (DPF) to greatly reduce particulate matter emissions and an absorber 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.
