6BT (5.9L) Cummins Turbodiesel 5.9L 12v Cummins Turbodiesel Specs, History, & Info The venerable 6BT Cummins was introduced in 1984 for various agricultural equipment applications by Case. Fast forward to 1989, Chrysler partnered with Cummins to offer the 5.9L Turbodiesel in their 3/4 and 1 ton Dodge pickups. The 12v Cummins quickly became a popular alternative to Dodge's V-8 gas engines, as the diesel generated nearly double the torque at low engine speeds and provided a significant increase in fuel economy, particularly while towing. The 12v Cummins, or 6BT, received an intercooler for the 1991 model year and the P1700 injection pump replaced the VE for the 1994 model year.
Cummins 6b Service Manual
The 12v Cummins is arguably the most popular of the various engine platforms that would follow as its simplistic nature and respectable performance characteristics are highly desirable. The 6BT was the first, and Dodge remains the only engine manufacturer to offer an inline 6 diesel in the pickup truck segment.
Cummins 6b Engine
5.9L 12v Cummins History & General Information Cummins produced the 5.9L 12v Cummins for Ram pickup applications through the 1998 model year, where it was phased out in favor of a more emissions friendly 24 valve platform. The engine's widespread applications include light and medium duty trucks, agricultural equipment, and construction machinery. A long stroke and undersquare bore-to-stroke ratio yield favorable low end performance, producing peak torque at a meager 1,600 rpm. Although the 6BT tips the scales at a hefty 1,100 lbs, its burly cast iron block and cylinder head contributes to the engine's superior reputation with regard to reliability and longevity. Additionally, its inline configuration eases service and repair efforts by providing generous amounts of workspace on either side of the engine block without the spacial restrains inherent of V-8 arrangements. 12v Cummins Heater Grid Cycle Schedule In place of a traditional glow plug system, the 6BT Cummins relies on a heater grid (single resistive heating element) mounted between the air horn and intake manifold to assist with cold starting. Cummins engines are well known for starting quickly and with minimal effort, despite the fact that the heater grid is only designed to cycle when the ambient temperature drops below 59° F.
