From weeks to days: Calibrate flex-fuel engines faster
Flex-fuel engines must deliver reliable performance across fuel blends ranging from pure gasoline to high-ethanol fuels. Calibrating the ignition angle for every combination of engine speed, load, and ethanol content creates a large measurement space. Engineers need to identify the thermodynamic optimum while remaining within the knock limit without spending weeks on the test bench.
Key challenges
Large calibration space
Numerous combinations of fuel blend, speed, load, and ignition angle must be evaluated.
Limited test bench capacity
Measuring every operating point manually requires considerable time and resources.
Complex engine behavior
Knock limits and thermodynamic behavior must be modeled accurately across the full operating range.
Quality requirements
Reducing measurement effort must not compromise calibration accuracy or engine performance.
Your benefits
Reduce test bench time
Shorten calibration and validation from several weeks to only a few days.
Improve calibration accuracy
Generate precise ignition maps for better fuel efficiency and engine performance.
Standardize the workflow
Make calibration repeatable, scalable, and less dependent on individual expert knowledge.
Accelerate new variants
Adapt engines faster for new derivatives and markets with different fuel standards.
