At the heart of every mission

Liebherr combustion engines are designed to perform reliably in the most demanding environments. With a robust design and proven durability, they deliver consistent performance, even under extreme conditions.

This exceptional robustness makes them suitable for a wide range of applications, including construction, agriculture, forestry, mining, power generation and defense, ensuring long service life and maximum uptime at the heart of every mission.

Liebherr combustion engines are designed with total cost of ownership and ease of maintenance in mind. Technologies such as the twin-scroll turbocharger support engine performance and operation.​

Extended service intervals further reduce downtime. Features such as the automatic poly‑V belt tensioner increase component lifetime, while oil change intervals of up to 1,500 hours significantly limit maintenance interventions.

Additional solutions, including the maintenance-free crankcase ventilation system for HV engines, simplify servicing and ensure reliable operation over time, keeping equipment running smoothly - at the heart of every mission.

Liebherr supports customers throughout the entire engine lifecycle with integrated service solutions designed for efficiency and reliability. Our combustion engines are developed with maintenance in mind, ensuring easy access to all service-relevant components for fast and straightforward servicing.

To further enhance diagnostics and maintenance, Liebherr has developed LiDIA, its proprietary diagnostic solution, enabling efficient condition monitoring and troubleshooting.

In addition, dedicated training programmes at the Liebherr Training Academy in Bulle ensure that operators and technical experts gain the knowledge required to operate and maintain engines safely and efficiently.

By combining smart design, advanced diagnostics and hands-on training, Liebherr ensures reliable operation and long-term performance—at the heart of every mission.

LiDIA provides advanced monitoring of key engine parameters, including oil pressure, fuel consumption, coolant temperature and load profiles—giving operators full visibility into engine performance at all times.

Real-time alerts enable fast response to potential issues, helping to prevent unexpected failures and minimise downtime. By supporting proactive maintenance, LiDIA improves reliability, optimises performance and increases operational efficiency.

With deeper insights and faster decision-making, LiDIA ensures your engines perform reliably - at the heart of every mission

At the Liebherr Training Academy in Bulle, customers and technical experts benefit from dedicated, hands-on training programmes designed to build practical expertise in combustion engine operation and applications.

Complementing these on-site sessions, a comprehensive range of web-based courses—from fundamental to advanced levels—offers flexible learning pathways and supports continuous professional development.

By combining practical experience with digital learning, Liebherr ensures that operators and specialists are fully equipped to operate, maintain and service engines safely and efficiently—empowering performance at the heart of every mission.

Liebherr combustion engines combine advanced combustion technology with in-house SCR-only aftertreatment systems designed to support compliance with stringent global emissions standards, including EU Stage V and US Tier 4 Final.​

By developing the combustion process—from injection to exhaust-gas aftertreatment—Liebherr continues to advance combustion, turbocharging and friction-reduction technologies while supporting reliable operation at the heart of every mission.​

Reducing global greenhouse-gas emissions is one of the major challenges of our time. We develop and investigate alternative powertrain concepts for different applications and operating environments. With a wide range of products serving industries worldwide, we recognise that different applications may require different technological solutions.​

That is why we take an open approach to powertrain technology and explore a variety of fuels for different requirements, operating environments and market specifications. This includes investigating hydrogen, ammonia, methanol and ethanol as potential fuels for industries that rely on powerful machinery and engines—at the heart of every mission.​
