Cummins is the world leader in heavy-duty diesel-engine production volume. DPF/SCR with AdBlue is standard on modern Cummins engines. The Cummins B-Series, ISX and QSB are the main engine families. The top Cummins ISX marks the power ceiling for American trucks.
EFILive, MM3 and MiniMax are the main tools for Cummins (not the standard WinOLS). The US Cummins community is the world's largest for Dodge Ram and heavy trucks. Cummins confidently reaches Stage 2 with hardware (turbos, injectors). The top Cummins ISX engines mark the power ceiling of the American truck segment.
