Exoskeletal engine

Okay kiddo, so let me tell you about an exoskeletal engine. Do you know what an exoskeleton is? It's like a shell, like the one that a crab or an insect wears on the outside of their body to protect their soft insides. So, an exoskeletal engine is like an engine that wears a shell or a frame on the outside to protect itself and work better.

Now, imagine you have a toy car. The way it moves is by using an engine that turns wheels connected to it. But sometimes, the car can't go over bumpy roads or climb steep hills because it's not strong enough. So scientists and engineers thought about putting an exoskeleton around the engine to make it tougher and more powerful.

Now, the exoskeletal engine looks like a big machine wearing a metal frame or a shell. This shell has several parts, which are designed to protect the engine and make it more efficient. One of the things that this exoskeleton does is to allow the engine to have stronger and larger pistons that can create more power. The exoskeleton also helps to make the engine lighter in weight, which means that it can work better with less fuel or battery power.

So that's what an exoskeletal engine is, a tough and powerful engine that wears an armored covering to protect itself and be more efficient.
