CUMMINS 4B3.9-G11 diesel engine (T2, 20 kW) is the CUMMINS 4B3.9-G11 engine, built for continuous duty in generator sets and industrial drives and delivers 20 kW.
The engine is supplied as a complete unit for coupling to an alternator, pump or machine: block, head, injection system, water pump and filters already fitted. The 4B3.9-G11 designation identifies displacement and aspiration layout, so spare parts are ordered by that code rather than by power rating.

Frequently asked questions
How do I know this engine fits my generator set?
The 4B3.9-G11 code must match the plate on the installed engine. If you are building a new set, start from the alternator rating and select the engine by speed and torque curve, not by nameplate kW alone.
Does it ship with documentation?
Yes. Every unit leaves with its datasheet and its 4B3.9-G11 identification code. If your purchase requires a certificate of origin or a conformity certificate, state it in the quotation request so it is issued with the order.
