Working I4 engine, engine block from @ericthepoolboy, pistons and crankshaft made by me. I made it actually work, can work with a electric motor. or any other motor that can be attached to the crankshaft. The model can also be used without any motors and electrical parts. Use as you like just respect the license. Have a great day!
