Haynes 4 Cylinder Engine Construction Kit

Haynes Engine Construction Kit: What is it?

It’s a scale model of a 4-cylinder, 4-stroke petrol engine… that works! And, with its clear casing, you can see how all the parts move inside it. Plus, it has an electronic engine sound and light-up spark plugs.

About the product

This build-it-yourself kit has everything you need to construct the engine, including all the parts, screws, and a screwdriver. Oh, and detailed, step-by-step instructions with diagrams.

How is it powered?

There’s no actual petrol involved. This engine runs entirely off 2 AA batteries, which aren’t included.

Why you should buy it

It’s a super-fun project that teaches you how internal combustion engines work!
