The register lists here five versions with 300 to 400 kW rated output at 1,900 to 2,000 rpm. The six-cylinder inline engine measures 130 mm bore and 150 mm stroke, maximum torque ranges from 1,890 to 2,523 Nm at 1,350 to 1,500 rpm. The engines are direct-injection, turbocharged and predominantly certified to Tier 4 (Final or Phase-in), in the 130 to 560 kW power category.
In this power class, the D946 drives large wheel loaders, crawler excavators and other heavy mobile earthmoving machines from Liebherr as well as outside manufacturers; with its own engine plant in Bulle, Liebherr covers the entire drivetrain development in-house, from four-cylinders to heavy six-cylinders.
On a used purchase, operating hours and the service history of the high-pressure injection system count, along with the condition of the turbocharger and charge-air ducting, the function of the diesel particulate filter and SCR catalyst with AdBlue dosing, and the tightness of the cooling system and intake tract; parts supply runs through Liebherr's own service network.
