C 8.3L
Proven technology for reliable power.
Like the B-Series, C-Series engines have established an unrivalled reputation for reliability. Engines in the series incorporate features to reduce maintenance and enhance performance in order to meet the most demanding requirements of generator set operation. Specification for the C-Series includes everything you would expect from G-Drives B-Series but at 8.3 liters and with a six-cylinder envelope the C-Series delivers greater power at standby, prime and base.
Cummins C8.3 has quietly improved, every year. Dual Ni-Resist piston inserts reduce friction, increase piston life and decrease oil consumption. The combustion chamber bowl, crank angle and helical gear have all been modified to help reduce noise. An in-line fuel pump delivers fuel at higher injection pressures for cleaner combustion, more power and lower emissions. The result is higher torque output from less fuel. And, because you can run a C8.3 on every kind of fuel from Jet-A to kerosene to diesel, it's right at home in the most remote locations.
