The 5.9 L Cummins, also known as the "12-Valve" Cummins was the first member of the Cummins B-Series to be used in a light truck vehicle. The 6BT used Bosch fuel systems, injector, and VE rotary pump and P7100 inline injection pumps. Some early 6BTs were supplied with CAV rotary pumps instead, before the Bosch system became the sole standard.
It was developed by heart surgeon Dr. Michael DeBakey [4] for blood transfusions [5] while he was a medical student in 1932 and later used by him for cardiopulmonary bypass [6] systems. A specialized nonocclusive roller pump (US Patent 5222880) [7] using soft flat tubing was developed in 1992 for cardiopulmonary bypass systems.
In 1919 Pierce-Arrow introduced its 524.8 cid (8.6-liter) straight-6 with 24 valves. The engine produced 48.6 bhp (0.09 bhp per cubic inch) and ran very quietly, which was an asset to the bootleggers of that era. [9] [10] [11] Multi-valve engines continued to be popular in racing and sports engines.

Bore and stroke are 83.5 mm × 76 mm (3.29 in × 2.99 in); it is a 60-degree V6 and weighs ...
A version with four valves per cylinder (for a total of 24 valves) was introduced in 1999. [6] The 24-valve versions use one camshaft for the intake valves of both banks (using rockers to reach the furthest bank) and the other camshaft for the exhaust valves of both banks (again, through the use of rockers).
