About the Piston black outline icon
The icon shows an engine piston seen head-on: a flat crown with a ring groove line, a small circular wrist pin at the center, an arched skirt, and a tapered connecting rod that ends in a round big-end bearing cap. It signals engine work and mechanical repair, which suits car service websites, garage booking apps, spare-part catalogs, engine diagrams and motorsport dashboards.
Proportions are vertical and symmetrical, with the crown block widest at the top and the bearing ring anchoring the base, so the shape stays balanced in a square frame. Pair it with wrench, gear, car battery and oil can icons for a service menu, and keep strokes at 24px and up.
This is the black outline version of the piston icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
