Latest Patents: Among Mendler's latest innovations is the hybrid electric turbocharger. This inventive design enables the impeller inlet of a turbocharger compressor to efficiently receive intake air from both an inner and an outer channel. The outer channel is pressurized by an electrically powered secondary compressor, which enhances air flow near the outer wall of the impeller inlet. This innovative approach not only prevents air backflow and surge but also allows for high boost pressures even at low mass flow settings. Notably, the system requires minimal electrical power, making it compatible with conventional 12-volt automotive batteries.

Another significant contribution from Mendler is the variable compression ratio engine camshaft drive. This invention features an endless band drive system with a variable center distance between the drive pulley and the driven pulley. It utilizes a rotatable control shaft to adjust the position of an endless band guide, ensuring a slackless operation regardless of changes in the pulley center distance. This unique design supports two or more compression ratio values, further refining engine performance and efficiency.
