Alternative Fuel Engine Testing

Enabling testing of fuel-agnostic internal combustion engine (ICE) families.

The need for cleaner vehicles, industrial machinery, marine ships, etc. when it comes to exhaust emissions, especially CO2, draws a distorted image for the future of ICE-based propulsion systems. Fuels such as natural gas, biofuels, alcohol fuels, hydrogen, and e-fuels are – depending on their application – promising alternatives for reducing emission and greenhouse gases. However, the increased variety of fuel options for ICE-based propulsion systems makes development and testing even more challenging, due to a significant increase in the complexity of the test facility installation. We have the right test system solutions available, which address the extended requirements for supply, measurement, and testing technology in combination with enhanced safety aspects. 

As part of the 2015 Paris Agreement, 196 countries committed to substantially reducing their greenhouse gas emissions to limit global warming. In 2021, the international community agreed to explicitly mention the burning of fossil fuels as the primary cause of climate change at the COP26 in Glasgow for the first time. Sustainable and near-zero carbon alternative fuels will be necessary to halve greenhouse gas emissions from hard-to-abate sectors, such as shipping, aviation, and trucking by 2050.

Alternative fuels are gaseous or liquid fuels for internal combustion engines that are created by turning renewable electricity into chemically bound energy carriers. Examples include hydrogen, methane, methanol, oxymethylenether (OME), dimethylether (DME), or Fischer-Tropsch fuels. Using these e-fuels can potentially help convert today’s internal combustion engines to effective carbon-neutral propulsion systems with zero-impact emissions.

Fuel Supply Infrastructure

To run engines on testbeds with alternative fuels, a suitably designed and sized, and correctly located storage and supply infrastructure is key. AVL headquarters in Graz has housed such an infrastructure for many years to support in-house test factory operation. Visitors are welcome to see how this infrastructure was successfully installed in a critical environment.

Upgrade / Transformation of Test Facilities

Having engines operated with new, alternative fuels on the testbed means that an extensive number of modifications and extensions need to be considered. Fuel consumption measurement, emission measurement instrumentation, combustion air, etc., and additional test cell safety measures are typical examples that need to be taken into account. We can help you upgrade these, and help you transform existing test cells for operation with new, alternative fuels.
