Cummins KTA19-G2 vs Yuchai YCMJ12520-D40
Compare Cummins KTA19-G2 and Yuchai YCMJ12520-D40 by recorded output, operating duty, frequency and engine specifications. Their listed displacements are 19 L and 11.73 L, respectively. Start with the same duty and frequency, then check each model’s source and package conditions. These records alone do not establish interchangeability.

Compare matching ratings
Read across a row to compare the same operating duty and frequency. kWe is electrical output; mechanical kW is power at the engine shaft. kVA is apparent electrical power and is shown only when kWe is missing, without converting it. “Not listed” means the record lacks that rating, not zero output. Continuous and prime duties are kept separate. Check source documents, units and site conditions before comparing values.
An emissions classification in the catalog is not proof of certification for your engine or installation. Confirm the exact model, applicable documents and generator configuration.
