The smarter system for excavators

Selective Catalytic Reduction (SCR) technology has been introduced by Liebherr in its aim to reduce nitrogen oxide emissions and comply with EU Stage V standards.

As emissions regulations tighten worldwide, machinery manufacturers are rising to the challenge with innovative solutions.

Liebherr, a global leader in heavy equipment manufacturing, has taken a proactive approach to meet the increasing demands for emissions control. Its solution is a cutting-edge, self-developed emissions system designed to complement Liebherr engines and simplify the European Union's Stage V process.

These emissions standards regulate the amount of pollutants from non-road mobile machinery (NRMM) such as construction equipment, agricultural machinery, and industrial engines.

The Stage V regulation, implemented in 2020, requires manufacturers to reduce emissions of:

• Particulate Matter (PM)

• Nitrogen Oxides (NOx)

• Carbon Monoxide (CO)

• Hydrocarbons (HC)

In response to stricter emissions standards, Liebherr has developed a proprietary injection system, along with a complete engine control system, ensuring the flexibility needed to adapt to a variety of emissions regulations across regions and countries.

A flexible approach

Liebherr's approach offers unmatched versatility in emissions management.

The company's standard basic engine can be easily adapted to meet the demands of diverse global markets, thanks to a modular design.

This enables small modifications or the addition of exhaust gas after-treatment systems to address different emissions regulations.

Liebherr's self-designed systems ensure that the engine architecture remains unified across various models and regions, simplifying maintenance and reducing operational costs.
