FPT Industrial has sealed a long-term deal to supply Liebherr's Switzerland-based engine manufacturing business with a new version of its N45.
The N45, a Tier 4 final / Stage IV compliant 4.5-litres, four-cylinder in-line engine is specifically designed for Liebherr and delivers 174 horsepower. The N45 features state-of-the-art technologies, such as the latest generation Common Rail injection system, and is characterized by high power and high torque, especially at low rpm, ideal to increase productivity in construction applications.
To ensure compliance with Tier 4 final / Stage IV emissions levels, the engine adopts FPT Industrial's patented High Efficiency SCR (HI-eSCR) system, which reduces Nitrogen Oxide (NOx) emissions by more than 95% through the use of SCR only; with no need for exhaust gas recirculation (EGR) or a diesel particulate filter (DPF). For countries requiring the adoption of filters, a DPF can be added to the HI-eSCR system, which makes the solution Stage V ready.
Based on the requirements provided by Liebherr and FPT Industrial's experience and know-how, the technical features make the specifically-developed engine stand out for its efficiency, robustness and quality, allowing it to achieve high performance in terms of load response, maximum torque and power. Meanwhile, the engine also delivers low fuel consumption and long maintenance intervals to ensure low operating costs.
