Definition: A system consisting of the parts of an engine through which burned gases or steam are discharged; see also exhaust system.

Alright class, settle down and let’s take a look! Today we’re tackling a word that sounds a bit… well, exhausted itself. Let's break it down. The dictionary gives us a pretty clear definition: “A system consisting of the parts of an engine through which burned gases or steam are discharged.” Now, let's put it into simpler terms – think about a car! When your car burns fuel to make you go vroom-vroom, it doesn’t just poof disappear. It makes smoke and hot gas, right? That’s the “exhaust” part. It’s all the stuff that comes out of the tailpipe! We have a special system – an exhaust system - designed to carry away this hot, smoky gas safely. Think of it like a chimney for your car's engine. It helps keep the air clean and prevents those fumes from bothering you. So, “exhaust” means: the release or outflow of something, especially waste gases from an engine. Does that make sense? Do you have any questions about where this ‘exhaust’ goes, or how it works? Let's discuss!
