We supply the Cummins B4.5 – a 4.5L inline 4 common rail diesel engine delivering 100-170kW and 700N·m torque with Tier 4 Final / Stage V certification. Unlike the old mechanical 4BT, this modern B-series engine features 1800-bar common rail and DOC+DPF aftertreatment (no SCR), making it the clean and simple choice for skid steers, mini excavators, compact tractors, and gensets in emission-regulated regions. As a China exporter, we offer complete engines, ECUs, DPF units, and wiring looms – all dyno-tested with data logs. We can also depopulate or calibrate the ECM for stationary genset or off-highway use. Send your equipment model, target horsepower, and emission requirement for a matched solution.
