At Agritechnica 2023, MAN Engines will be showing a wide range of proven as well as completely new products under the motto “Powering The Green Transformation – Off-road solutions for the future”. The highlight of the trade fair appearance of MAN Engines—a business unit of MAN Truck & Bus—is the MAN BatteryPack.
The MAN BatteryPacks are based on many years of Group experience and are already being used successfully in Truck & Bus SE’s own battery-electric commercial vehicles. Customers in a wide range of industries will be served with customer- and application-specific solutions—as has been the case with combustion engines in the past.
The company plans to mass-produce high-voltage batteries from 2025 onwards and is investing around €100 million in the Nuremberg site to this end. For the recycling of the batteries, MAN is planning a closed loop with second-use concepts and subsequent raw material recovery.
With a focus on reducing CO2, MAN Engines will also be presenting the MAN H4576 hydrogen combustion engine at Agritechnica. This is designed for high-performance agricultural machinery and off-road applications in the 500 hp class.
The newly developed MAN H4576 hydrogen combustion engine with a displacement of 16.8 liters is based on the proven engine geometry of the MAN D3876 diesel engine and shares about 80% of its basic components with it. The MAN H4576 has modifications to the hydrogen supply, engine control and exhaust gas control to ensure efficient combustion.
MAN already has many years of experience in hydrogen engine technology and, due to this expertise, can quickly bring the MAN H4576 to market. The PistenBully 800 from Kässbohrer Off-Road Vehicles is already conceptually designed to be powered by the MAN H4576.
Hydrogen combustion engines are a promising approach to accelerate the decarbonization of off-road drives. As soon as the market is ready, MAN Engines will offer tailor-made solutions.—Mikael Lindner, Head of MAN Engines
MAN Engines will also showcase the E3872 gas engine—a bridging technology on the road to decarbonization. By running on natural gas, biogas or special gases, CO2 can be reduced locally by around 10 to 20% compared to a conventional diesel engine. The high efficiency of 44% as well as the use of the waste heat from the engine in power generation make the MAN E3872 with 735 kWel at 1,500 rpm an efficient and environmentally friendly solution in decentralized energy concepts. The gas engine from MAN Engines is H2-ready and can be operated with up to 20% hydrogen by volume.
