The 4.5 litre N45 diesel engine from FPT Industrial for construction applications

Engine manufacturer FPT Industrial has signed a deal with Liebherr to supply engines.

FPT will supply its 4.5 litre four cylinder diesel rated at 130 kW to Liebherr Machines Bulle in Switzerland. It is a Tier 4 Final / Stage IV version of the NEF series N45 diesel with selective catalytic reduction (SCR) exhaust treatment.

FPT said it is specifically designed for Liebherr. It is turbocharged, has a common rail injection system, and four valves per cylinder. Also featured is the Italy-based manufacturer’s patented High Efficiency SCR (HI-eSCR) system, which reduces emissions of oxides of nitrogen by more than 95 % just using SCR, without needing exhaust gas recirculation (EGR) or a diesel particulate filter (DPF). A DPF can be added to comply with Stage V emissions regulations.

Efficiency, robustness and quality, are key features of this engine, FPT said, allowing it to achieve high performance in terms of load response, maximum torque and power. Low fuel consumption and long maintenance intervals are further benefits that minimise operating costs, FPT said. Engines of this capacity are used in the upperworks of mobile cranes or as the main engine in smaller construction machines.
