Exciting Development News: Piezo Direct Injection powered by VEMAC 🚀
Since the beginning of this year, VEMAC GmbH & Co. KG has been proud to collaborate with HWA AG on the development of a Series Piezo Power Control Unit (PCU) for HWAs fascinating HWA EVO project.
As part of our role as a HW & SW development full service provider for Automotive Control Units, we designed the series PCU according to functional safety standards to obtain road approval.
PCU features:
- Specially developed diagnostics functions tailored for HWA ⚡️
- Temperature and pressure compensation for the Piezo Injectors, ensuring precise and reliable operation under all conditions 🔥
- Rapid series development in less than a year 🏎
A series development like this, which only lasted three-quarters in 2025, is only possible thanks to the VEMAC RCP System “PZAmpII”, which enables a rapid, near-series prototype development while maintaining high reliability and precision.
The HWA EVO project brings the legendary EVO 190II back to life with state-of-the-art technology, combining classic design with modern performance and reliability. VEMACs contribution ensures that the injection control system meets the highest standards in safety, precision, and durability, supporting HWA in creating a truly exceptional vehicle.
We’re proud to be part of this incredible journey, pushing innovation and excellence in automotive development.
