Designing a productive engine to suit the requirements of the mining industry has been one of Liebherr’s main objectives: A high performing engine that achieves higher levels of productivity.

Made for productivity

Specifically designed to meet the demands of extreme operating conditions in the global mining industry, the D9812 engine offers outstanding performance for every mining application. The engine benefits from a new modular turbocharging system providing optimum air flow and volume to achieve power requirements. This results in the D9812 engine having the best “In Cylinder Power Density” of its class, opening the doors to better productivity outcomes from a single engine.

Liebherr designed a highly responsive and reactive engine with superior performance, providing the required horsepower at the precise moment resulting in more productivity.

As a result, your excavator will deliver faster cycle times enabling it to load more tons per hour, and your truck will accelerate and climb faster on grade enabling it to move more tons per hour.

Best-in-class dynamic behaviorAll the power you need for your machine

The D9812 delivers outstanding low fuel consumption by matching the exact engine subsystems from the highest quality of in-house developed key components, such as the Liebherr engine control unit and the Liebherr common rail fuel system. This results in a maximum efficiency improvement of up to 45%, greatly increasing fuel savings…keeping in mind that an increase of 1% efficiency can result in saving thousands of liters/gallons of fuel per year and the corresponding financial savings.

In addition, the engine’s capability of reducing the rated speed from 1,800 rpm to 1,500 rpm can further save between 3% to 5% fuel consumption and extend engine component life.

High productivity at low operating costs. This is the commitment of this new engine born for mining.

Low operating costs

The D9812 has been designed for extended maintenance intervals. Its carefully thought-out and maintenance-friendly design allows quick and easy servicing. As a result, the overall scheduled downtime for the D9812 engine has been reduced, less maintenance and more availability. Furthermore, the engine has been designed with superior reliability in mind for the harshest mining environments, providing the highest operating ability for your machine. Additionally, down-speeding by 300 rpm results in an up to 20% increase of engine lifetime.

Furthermore, the Liebherr group together with its logistic and service networks provide parts supply and technical service support worldwide. Overall, we are focusing on saving your time, increasing your equipment availability and optimizing your total operating costs so your total costs of ownership meet or exceed your expectations and forecasts.
