We offer the Cummins QSB4.5 – a 4.5L inline 4 common rail diesel engine delivering 100-160kW and 750N·m torque with Tier 3 / Stage IIIA certification. Unlike the Tier 4 B4.5 with DPF, this QSB version uses cooled EGR only – no DPF, no SCR – which means lower upfront cost, simpler maintenance, and no regen cycles for loaders, forklifts, compressors, and gensets in regions with lower emission requirements. As a China exporter, we supply complete engines, ECUs, full harnesses, and EGR coolers – all dyno-tested with data logs. We can also depopulate the ECM to remove speed or torque limits for genset or stationary applications. Send your equipment model, current engine serial number, and emission requirement for a direct replacement quote.
