CUMMINS 5.9

The 5.9 liters (360.0 cu in) 6BT, aka the Cummins "12-valve" was the first member of the "B" engine family to be used in a light truck vehicle. The 6BT used Robert Bosch GmbH fuel systems, injector, and VE rotary pump and P7100 inline injection pumps. Some early 6BT's were supplied with CAV rotary pumps instead, before the Bosch system became the sole standard. This engine started life in 1984 designed as an agricultural engine, for use in Case agricultural equipment.[3][full citation needed] After 1989, the 6BT engine was used in light duty, medium duty and select heavy duty trucks and buses. Appearing in the 1989–1998 Dodge Ram pickup truck, it became a popular alternative to the large V8 gasoline engines normally used in full-size pickup trucks, since it produced the torque at low engine speeds, and significantly better fuel mileage. During that time, the Dodge Ram was the only diesel pickup that featured Direct Injection and did not rely on glowplugs for cold weather starting.[3] The 1989–1993 Dodge Ram pickup engines were rated at 160 horsepower (119 kW; 162 PS) and 400 pound-feet (542 N·m). The fuel systems for these Dodge Rams used Bosch injectors and Bosch VE mechanically controlled fuel injection pumps. Charged air coolers were added in 1991. In 1994 when Dodge introduced the completely restyled Ram, changes were made to the 6BT as well.[WIKI]
