Fraunhofer researchers develop new low-cost dry-film electrode production process

Green Car Congress

Production at locations with high electricity prices—such as Germany—is, therefore, very high-cost. The Fraunhofer engineers want to change this. Our dry transfer coating process aims to noticeably reduce the process costs in electrode coating. This drying procedure usually causes high electricity costs.

Mahle Jet Ignition ready to be integrated into existing production engines

Green Car Congress

MAHLE Powertrain’s (MPT’s) latest development of its passive MAHLE Jet Ignition (MJI) technology ( earlier post ) can now be added into existing engine designs with only minimal changes to the final machining process. A whole system engineering approach is the way to get the best from MJI. —Adrian Cooper.
