AB Volvo Penta TAD 1661VE

The register lists here 9 versions with 256 to 515 kW rated output at 1,800 to 1,900 rpm, all inline six-cylinder engines with 131 to 144 mm bore and 158 to 165 mm stroke. All engines use wastegate turbocharging and common-rail direct injection, the fuel entered is ultra-low-sulphur diesel (7 to 15 ppm), and the emission stage is consistently Interim Tier 4. Maximum torque runs from 1,745 to 3,220 Nm at 1,200 rpm, the power category is 130 to 560 kW. The register distinguishes six build stages from I to VI; the range is certified for both the other states and California.

Engines of this size class are the standard drive for stationary and mobile industrial applications away from road traffic: standby generators, pumps, cranes and heavy construction and quarry machinery that need a robust, high-torque diesel block with industrial approval. Volvo Penta supplies its own applications and numerous OEM customers in the industrial business with them.

On a used purchase, operating hours and service history, the condition of the wastegate turbocharger and its actuation, the tightness of the charge-air cooler and common-rail system, and the condition of the exhaust aftertreatment count, which on Interim Tier 4 engines includes, depending on the application, a particulate filter and exhaust gas recirculation. Parts and service run through the Volvo Penta dealer network.
