They were introduced in the 1989 Ram trucks, and are still being offered every bit an optional engine for the latest line of Rams. The Cummins diesel fuel engine had two main major development outputs, the 5.9L engine that ran from 1984 to 2006, and the 6.7L engine that was introduced in 2007 and is currently equipped on the latest Dodge trucks.

12-Valve five.9L Cummins Diesel Engine

The 12-valve Cummins v.9L diesel engine was first conceived in 1984 and was intended for agronomical purposes. It was but in 1989 that information technology was equipped in a Dodge Ram. It gained immediate popularity because of its ability to exist twice equally fuel efficient when compared to gasoline engines, and produced nearly twice equally much torque when running on low speeds. The 12-valve version ran from 1989 until 1998. Its bore and stroke was 4.02 inches past 4.72 inches, and its pinch ratio was 17.0:one. It utilized an Overhead Valvetrain (OHV) with two valves per cylinder, and a solid-lifter camshaft. Throughout its product it had a rated output of 160 to 215 horsepower at 2,500 rpm, and a torque ranging from 400 to 440 lb.-ft. at 1,600 rpm.

24-Valve v.9L Diesel Performance

In 1998 the 5.9L Cummins had a major upgrade, irresolute the powertrain from a 12-valve to a 24-valve engine to follow new emission regulations. It utilized a new fuel injection system known as the "Collaborate System B (ISB)," which used the VP44 rotary injection pump made by Bosch. A high output (HO) was adult for the ISB in 2001, increasing the engine's overall power output. This engine had a bore and stroke of 4.02 inches by 4.72 inches. It had a pinch ratio of 16.three:1 for the not-HO version, and had a compression ratio of 17.2:i for the HO version. It utilized the same OHV configuration with solid-lifter camshaft, merely with four valves per cylinder. It generated an output of 235 to 325 horsepower at 2,900 rpm, and a torque of 410 to 610 lb.-ft. at 1,600 rpm.

6.7L Diesel fuel Engine

The six.7L version is the engine equipped on the latest Rams. This engine was introduced in 2007, and was developed to follow stricter emission regulations. This new engine was equipped with a Variable Geometry Turbocharger, a special diesel particulate filter and an Exhaust Gas Recirculation organisation. It had a bore and stroke of 4.21 inches past 4.88 inches, and a compression ratio of 17.three:1. It utilized the same OHV configuration equally the 24-valve model of the 5.9L engine. Its output was rated at 350 horsepower at three,013 rpm. Trucks with manual transmission had a torque of 650 lb.-ft. at 1,500 rpm, while automatics generated a torque of 610 lb.-ft. at the same rpm range.
