Ex-Porsche Head Extends the Life of Traditional EnginesDecember 14, 2018
Former head of Porsche Wendelin Wiedeking became a shareholder of the German startup MWI Micro Wave Ignition AG, which intends to extend the life of traditional ICE. He developed an alternative ignition system to help reduce fuel consumption by 30 percent and reduce harmful emissions by 80 percent.
The technology promoted by MWI implies the use of a pulsed microwave instead of a spark discharge. It can be adapted to any modern engines, without the need for changes in the design. Tests of the experimental two-cylinder engine showed that the fuel consumption during microwave ignition is reduced by 13–20 percent (theoretically up to 30 percent), and the level of harmful emissions due to a lower air-fuel mixture combustion temperature can be reduced by 80 percent.
MWI has already begun negotiations with Korean and Chinese automakers. One of the potential partners is called Hyundai. In addition, the startup entered into an agreement with the Fach Auto Tech team, which participates in the Porsche Mobil 1 Supercup monocube. It is assumed that the microwave-based ignition system will be used on race cars from next season.
In another way, also leading to lower fuel consumption, Mazda went. The Japanese company developed the Skyactiv-X engine, which operates on a modified HCCI (Homogenous Charge Compression Ignition) cycle – ignition of a homogeneous compression mixture. This unit debuted on the new Mazda3, where it became part of a hybrid power plant.
