D954 Construction

The Liebherr 4-cylinder in-line D954 engine has a displacement of 7.4 liters and generates a maximum torque of 1,423 Nm at 1,300 rpm to achieve a power output of 220 kW. The robust and compact design of the D954 is built to withstand the harshest conditions of the construction and agriculture industries. This four-cylinder engine comes with an integrated centrifugal water pump and closed crankcase ventilation system, ultrafine fiber oil filter, fuel fine filter on engine as well as twin scroll turbocharger that considerably improve fuel consumption. The engine fulfils the demanding EU Stage V exhaust emission standards and can be fitted with Tier 4 final solutions. Our engine condition monitoring solution and LiDIA diagnostic tool, together with a long life service further extend reliability and minimise engine down time.
