Perkins – other nonroad diesel engines: the collective page of the two- to six-cylinder ranges outside the named models, 4 to 678 kW, Tier 3 to Tier 4 Final, direct and indirect injection
Perkins of Peterborough has belonged wholly to Caterpillar since 1998 and has supplied diesel engines for farm machinery, construction equipment and generator sets since the 1930s; the type logic combines a four-digit Perkins range number (1104, 1204, 1206, 2206, 2506) with a suffix letter for the generation (D, E, F, J) and often the parallel Caterpillar displacement figure in litres. This page gathers the engines the register could not assign to a named range; notable is the mix of direct injection and the indirect injection still common on the smaller cylinder counts, plus two parallel fuel specifications, the US ultra-low-sulphur diesel standard and Perkins' own distillate diesel specification for export markets.

The register lists here 352 versions with 4 to 678 kW rated output up to 2,800 rpm, from two- to six-cylinders with 67 to 145 mm bore and 72 to 183 mm stroke, torques from 18.6 to 5,500 Nm. Tier 3 leads with 210 versions ahead of Interim Tier 4 with 71 and Tier 4 (Final or Phase-in) also with 71; a portion of the engines is certified only for states outside California.
The engines cover the mid-range power segment from mini excavators through wheel loaders to medium-size generator sets; here Perkins serves both Caterpillar's own construction machinery and a broad field of independent farm and construction machinery makers.
On a used purchase, operating hours count, on indirect-injection engines the glow-plug system and cold-start behaviour, on direct-injection engines the injectors and injection pump, the turbocharger and its boost-pressure control, and on the newer Tier 4 versions the exhaust aftertreatment; parts supply runs through the dense Perkins dealer network.
