Summary

The Zero Vibration Generator ZVG (50kWe) Volume Design is the consequent evolution of the existing ZVG (40kWe) with focus on cost reduction, technical improvement, and elimination of emissions. The ZVG comes with new and highly innovative technical optimizations such as a balancing system to compensate unbalances of the 1st, 2nd and higher orders, the usage of only one generator and a compensation mass to eliminate the rolling torques generated during transient operations. It can also be operated with the “green” fuel methanol for a CO2 neutral, NOx minimized and particle free operation. Using methanol, the engine can be operated with a compression ratio above 1:20 with an additional increase of combustion efficiency. Obrist Powertrain will present the current design of the ZVG as well as the test bench results for gasoline and methanol.
