AVL engine for CO2-neutral heavy vehicles – steiermark.ORF.at


Research is being carried out worldwide into environmentally friendly alternatives in transport. AVL is also involved and is promoting the development of a hydrogen-based combustion engine for CO2-neutral transport.

The Graz-based company AVL is continuing the development of the latest generation of the internal combustion engine, which was launched in 2019. The engine is specially tailored for use in heavy-duty vehicles and is intended to reduce greenhouse gas emissions from heavy-duty vehicles with more than 3.5 tons of payload.

Europe should become climate neutral by 2050

The company is currently developing a hydrogen internal combustion engine based on in-depth knowledge and many years of research experience in this area. AVL is thus pushing the pan-European goal of becoming the world’s first climate-neutral continent by 2050.


The aim of the development project is to improve the potential of both a multiport engine and a hydrogen direct injection engine for direct drive of a commercial vehicle with an existing standard drive train in the area of ​​efficiency. AVL uses a 12.8 liter natural gas engine as the basis for the development and has set the performance target at 350 kilowatts.

Heavy vehicles as CO2 ejectors

In 2019, commercial vehicles with a payload of more than 3.5 tonnes were responsible for 240 million tonnes of greenhouse gas emissions in the European Union, which corresponds to around a quarter of all road traffic-related CO2 emissions within the EU. In order to become the first climate-neutral continent in the world by 2050, Europe must significantly reduce CO2 emissions from heavy goods vehicles in the coming decades. More CO2-neutral transport solutions are needed for heavy haulage and long-distance transport. Specific solutions are required here that enable the rapid refueling of carbon-neutral energy sources to support the work cycles of trucks and buses.

AVL-Motor marks the beginning of a new era

Although battery electric solutions perform well, the production of hydrogen by electrolysis is the easiest and most efficient way to chemically store renewable electrical energy, according to AVL. Hydrogen can be used not only as a fuel for fuel cell electric vehicles but also as a fuel for an internal combustion engine. Based on the results collected during development, AVL is well prepared for the upcoming challenges in the production development of a hydrogen internal combustion engine.

AVL was convinced that these engines will represent the gateway to a future hydrogen refueling infrastructure. In the coming decades, hydrogen internal combustion engines and hydrogen fuel cell electric vehicles will use the same refueling infrastructure, said an AVL broadcast on Thursday, which means that hydrogen internal combustion engine technology is paving the way for a carbon-neutral freight transport sector.
