For a budding mechanical engineer or mechanic.
This perfectly explains the workings of an internal combustion engine.
The one I bought many years ago worked for about 7-8 years, but finally the timing belt broke. That happens in real engines also!

If you you want your child to know how a gas engine works, this is a kit they should have. I helped my kids assemble one of these kits years ago. It's a good sized working model and it still works, (if I replace the batteries).
The finished engine measures 11" x 9.5" x 6" .
