Deutz TTCD6.1L6

The register lists here 68 versions with 18 to 520 kW rated output at 1,500 to 2,700 rpm, from two- to eight-cylinders in inline (63) and V (5) configuration, with 90 to 132 mm bore and 90 to 145 mm stroke, all with direct injection. Fuel splits almost evenly between ultra-low-sulphur diesel (35) and the older low-sulphur diesel (33). Among the emission stages Interim Tier 4 leads with 37 ahead of Tier 4 (Final or Phase-in) with 17 and Tier 3 with 14 versions; the 130 to 560 kW power category is the largest with 20 versions, model years run from 2011 to 2026.

Deutz engines of this range drive construction machinery, forklifts, farm machinery and stationary generator sets; as one of the last large independent European engine makers, Deutz supplies numerous construction- and farm-machinery makers without their own engine production, competing with Kohler, Yanmar and Perkins.

On a used purchase, operating hours count, the condition of the turbocharger (waste-gate design on the majority, some of the smaller engines remain naturally aspirated), on the air-cooled D914 models the fan wheel and cooling fins in place of a coolant circuit, the injection pump or injectors, and on Tier 4 Final versions the exhaust aftertreatment; spare parts through the DEUTZ dealer network.
