Model engine

A model engine is like a toy car engine, but smaller. It is built to look like a real engine with cylinders, pistons, and a crankshaft. It is usually made of metal and uses gas or electricity to make it work.

When you turn on the engine, it starts to move the pistons up and down. This movement makes the crankshaft move too, which is connected to a propeller or wheels. This propels the model car or airplane forward.

Think of it like a little helper for your toys. It makes them go faster and look more realistic. It's fun to play with and can teach you how real engines work too!
