Twelve valve Cummins – An engine with a total of 12 valves. The most commonly used Cummins engines are the 6BT5.9 and 6CT8.3.
Cummins 6BT series engine
The 6BT 5.9 is a twelve valve Cummins engine with an inline six-cylinder design, producing a maximum power of 118kW (2600rpm). Some enhanced models can achieve even higher power outputs, reaching 140kW or even 151kW. In the truck sector, the Cummins 6BT engine performs exceptionally well. With a maximum horsepower of 260PS and a peak torque of 1020N·m, it is widely used in generator sets, construction machinery, and commercial vehicles.
Cummins C Series Engine
The 6CT 8.3 is a twelve valve Cummins engine with an inline 6-cylinder design, a displacement of 8.3L, a maximum power output of 179kW, and a net weight of 700kg, meeting the China III emission standards. Its core power unit optimizes intake efficiency through intercooled turbocharging technology, and in conjunction with the diesel combustion system, delivers high torque at low speeds, meeting the power demands of construction machinery under heavy-duty conditions such as excavation and loading. The cylinder block is made of high-strength cast iron, and the wear-resistant design of the piston rings and cylinder liners extends the engine’s service life in harsh environments.
