AVL Emission Key Visual

With increasingly strict emissions restrictions across the world, and demand for affordable vehicles with low fuel consumption that do not sacrifice comfort, the automotive industry is facing enormous challenges. The hybridization of propulsion systems, along with further optimization of internal combustion engines, is an important technological step in advancing the transition to more sustainable mobility. Demonstrating compliance with the emissions limits for vehicles requires state-of-the-art test solutions, a new generation of portable measurement systems for testing in real-world driving conditions, as well as totally new methodology for developing propulsion systems and vehicles fulfilling these new conditions. AVL provides excellent solutions and support in all areas.

How Did ICE/Hybrid Propulsion Testing Evolve?

In the past, test beds were gradually developed to bring an increasing number of driving situations from the road to the lab, enabling tests to be performed in a repeatable manner. This progress refined the development of the internal combustion engine (ICE) on the test bench, which improved the level of the vehicles significantly. Then, OEMs had to ensure that their vehicles were compliant with the Real Driving Emissions (RDE) test. Previously, it was sufficient to comply with emissions in the legally required cycles. Now the vehicle’s entire operating range must be tuned to optimally fit the emission limits, and the adjustments have to work for standard conditions for a broad range of routes (urban, countryside, highways, etc.), traffic situations, or any kind of weather or road conditions (heat, cold, rain). The impact of different driver types also needs to be considered.

How Do We Solve the Challenges in ICE/Hybrid Propulsion Testing?

The increased complexity of hybrid propulsion systems means that standard development methodology has started to reach its limits. This is because a disproportionately high number of different test runs is required to fully cover all driving situations. We offer a solution to the problem, using a model-based development approach. This optimizes the development tasks considerably, by employing physical, empirical models for the engine, exhaust gas aftertreatment, and the entire system.

In addition, regarding RDE, we have introduced a new generation of portable emissions measurement systems (PEMS). Based on our longstanding experience in automotive test systems, we have a profound understanding of the newly evolved needs, and provide solutions that help our customers overcome these challenges. From 100% virtual test beds to 100% real-world testing, we support all stages of the development process with our advanced solutions.

Besides hybridization, fuels such as hydrogen, e-fuels, natural gas, biofuels, and alcohol fuels are promising alternatives for reducing emissions and greenhouse gases. However, this variety of fuel options for engine-based propulsion systems leads to challenges in complex development and testing facility installations. We have the right testing solutions available to address the extended requirements for supply, measurement, and testing technology, in combination with enhanced safety aspects.
