Cummin’s

A lot has changed since the 5.9L Cummins B-series engine was first offered in ’89 Dodge pickups. The injection systems, cylinder heads, emissions equipment, and turbos have all seen dramatic improvements over the last 20 years. However, the one thing that Cummins has never altered was the displacement. During the same time period, General Motors upsized its diesel from 6.2L to 6.5L, and then to the current 6.6L engine for the Duramax. Ford sold 6.9L, 7.3L, and 6.0L in the past, and currently sells 6.4L Power Stroke engines, continually improving in order to meet various performance, fuel economy and emissions requirements. The 6.7L Cummins is the latest of the B-series engines, introduced mid model year in 2007. With an introductory rating of 350 HP & 650 lb-ft, it is also the most powerful B-series ever offered. The 5.9L ISB was replaced by the 6.7L to meet strict new diesel emission requirements. To meet such requirements, the 6.7L is equipped with an EGR (exhaust gas recirculation) system, a variable geometry turbocharger (VGT), and a diesel particulate fitler designed to reduce diesel particulate matter by more than 90 percent. A new, higher-pressure version of the Bosch direct injection system is used. For the 2013 model year, the Cummins was made available in three variations, the most powerful of which is rated at 385 hp and 850 lb-ft of torque.
