Optimizing hybrids FOR COST AND EFFICIENCY

AVL engineers detail a modular engine program suitable for all forms of hybridization.

The electrification of the powertrain is a prerequisite to meet future fuel consumption limits, while the internal combustion engine (ICE) will remain a key element of most production-volume-relevant powertrain concepts.

The range presented by AVL will include parallel hybrids, 48V- or high-voltage mild or full hybrids, up to serial hybrids. In the first configurations, the ICE is the main propulsion, requiring the whole engine speed and load range including the transient operation. In serial hybrid applications, the vehicle is generally electrically driven; the ICE provides power to drive the generator, either exclusively or supporting a battery charging concept. When the ICE is not mechanically coupled to the drivetrain, a reduction of the operating range and thus a partial simplification of the ICE is achievable.
