Caterpillar – further nonroad diesel engines: the collective page for large engines outside the named series, six- to twenty-cylinder units from 147 to 4,488 kW for mining, power generation and marine use
Caterpillar Inc., headquartered in Irving, Texas, is the world's largest maker of construction and mining machinery and has built its own diesel engines since the 1930s; this page gathers the large engines the register could not assign to any named main series, from the six-cylinder 2000 and C series to the V-configuration 3500 and 5000 series. Models such as the 3508C, 3512C and 3516C are V8 to V16 engines of the 3500 series, while the 5006C to 5016C designations cover the even larger stationary engines of the 5000 series.

The register lists 36 variants here rated from 147 to 4,488 kW at 1,200 to 2,200 rpm, six- to twenty-cylinder engines (23 inline, 13 V-configuration) with a bore of 105 to 175 mm and a stroke of 127 to 220 mm. Maximum torque ranges from 936 to 23,810 Nm at 900 to 1,800 rpm. Among emission tiers, Tier 2 leads with 14 variants ahead of Tier 4 (Final or Phase-in) with 12, while Interim Tier 4 and Tier 3 each have 5; the 130–560 kW power category is the most common with 12 variants, followed by 560–2,237 kW with 9 and above 560 kW with 7.
Engines of this size drive mining haul trucks, mining equipment, emergency generator sets for hospitals and data centres, and marine propulsion; in this segment Caterpillar competes chiefly with Cummins, MTU and Volvo Penta. The wide spread of emission tiers from Tier 2 to Tier 4 Final reflects the long certification span of large stationary and mobile engines, which are often produced unchanged for many years.
When buying used, engines of this class call for a check of running hours and the service history of injection pumps or injectors, the condition of the charge air cooler and turbocharger, the tightness of the cylinder head gasket and oil pan, and, for stationary sets, the condition of the radiator and silencer; spare parts and service run through the worldwide Cat dealer network.
