Cummins B Series

Advanced design and sophisticated manufacturing increase its high strength, heavy-duty work ability, using Holset waste-gate makes power ability better.

Integrated design block, cylinder heads and other parts, "a pluripotent", reducing the connections, 40% fewer parts than other similar engines, the failure rate is greatly reduced.

Excellent reliability using forged steel-camshaft and crankshaft, high- strength cylinder design, many parts cast in the cylinder lead to a capability of stiffness and high pressure.

High-pressure fuel pump rotor lower fuel consumption, lower noise

All the Cummins B serie engines parts are available.
