Cummins – other nonroad diesel engines: the collective page from the compact B engine to the 18-cylinder heavy engine, 46 to 3,245 kW, Tier 2 to Tier 4 Final, from Columbus, Indiana
Cummins is an independent engine manufacturer founded in 1919 in Columbus, Indiana, and one of the world's largest suppliers of nonroad diesel engines. This page gathers the versions from the US EPA certification data that the register could not assign to a named range – from the compact B engines badged QSB3.3 to QSB7 (derived from the classic 4BT/6BT) to large engines whose bore of up to 190 mm and cylinder count of up to 18 point to the K/X class, such as the QSK range for mining and power-generation applications; the exact meaning of individual engine-family codes such as SCEXL050.AAD remains internal to the manufacturer and is not speculatively unpacked here.

The register lists here 113 versions with 46 to 3,245 kW rated output at 1,200 to 2,500 rpm, from four- to 18-cylinders with 94 to 190 mm bore and 100 to 210 mm stroke. Maximum torque ranges from 198 to 20,564 Nm, model years from 2011 to 2026. Among the emission stages, Tier 2 leads ahead of Tier 3 and Tier 4 (Final or Phase-in); the power category above 560 kW under 40 CFR 1039 is the largest group, showing this collective page's focus on large engines.
Cummins engines of this size power mining haul trucks, standby generator sets, locomotives and stationary power plants; in the mid power range they appear in construction machinery and large farm equipment of numerous outside brands. Cummins competes here chiefly with MTU/Rolls-Royce Power Systems and Caterpillar.
On a used purchase of the large turbocharged engines, the service history of the charge-air cooler and turbocharger matters, on the older Tier 2 engines without exhaust aftertreatment operating hours and oil consumption count above all, and on the newer Tier 4 versions the function of the diesel particulate filter and SCR catalyst; spare parts and service run through the worldwide Cummins dealer network.
