Cummins – other heavy-duty highway engines: the collective page of the B, ISB, ISV and ISX12 ranges outside the named models, diesel and natural-gas variants, 200 to 500 kW, model years 2013 to 2026
Cummins Inc. of Columbus, Indiana, founded in 1919, is one of the largest independent makers of diesel and gas engines for heavy commercial vehicles worldwide. This page gathers the on-highway engines the register could not assign to a named range, from the mid-duty B6.7N range through the ISB and ISV5.0 models to the heavy ISX12 range for long-haul trucking, plus the natural-gas variants marked with a G, ISBG and ISLG; the ISB, ISL and ISX prefixes traditionally denote different Cummins build sizes and duty classes.

The register lists here 67 versions with 200 to 500 kW rated output at 1,761 to 3,200 rpm, model years 2013 to 2026, with torques from 520 to 1,700 Nm at 1,000 to 1,600 rpm. Among the diesel versions direct injection (54) prevails over electronic direct injection (7), while six versions running on compressed or liquefied natural gas use throttle-body injection, typical of spark-ignited gas engines.
The ISX12 range is Cummins' flagship for long-haul tractor units, while the B6.7N engines drive medium-duty trucks and coaches; the ISBG and ISLG natural-gas variants target emission-sensitive fleets such as city buses and refuse trucks. In the North American heavy highway-engine market, Cummins competes chiefly with Detroit Diesel, PACCAR MX and the Volvo and Mack engines.
On a used purchase, mileage and service records count, on the diesel variants the condition of the injection pump or injectors and turbocharger, on the gas engines the condition of the gas system and spark plugs in place of a glow or pre-heat system, and depending on model year the exhaust aftertreatment with particulate filter and SCR catalyst; spare parts run through the dense Cummins dealer network.
