I've officially worked on cars, albeit on an amateur level, for about 18 years now. And as much as I'd like to say that I know everything about engines, I don't. But you know what? Neither do most mechanics.
You probably know that an engine needs air, fuel and spark to run. Plus, there's a number of things like pistons, valves, bearings, etc. that somehow work together to make a vehicle move. What's the difference between a camshaft and a crankshaft, anyway? Ever hear of a Wankel Rotary engine? How about those crazy Gnome Rotary motors on biplanes?
Glad you asked - and here's your answer!
Thanks to a clever gent named Matt Keveney, it's easy for even a beginner to find out how an engine works, whether it's powered by gasoline, diesel, steam or even rocket fuel.
So whether you're an amateur, or a seasoned pro with multiple builds under your belt, take a few moments and check out his page.
Don't worry - there won't be a quiz just yet.
