Bosch's logo is something like a sparkplug (the thing used in internal combustion engines). To this day, the 'mobility' division is the biggest one. See https://www.bosch.com/stories/creation-of-the-bosch-logo/

Decades ago I actually had an offer to work for them as a research student working on optimising internal combustion engines.
