Animated Engines is a site by Matt Keveney that has some great animated illustrations of a variety of engines that shows how they work. In addition to the animation, there are step by step explanations of how the the engine works and even some history of that type of engine. 


Engines include 2 and 4 stroke internal combustion engines, diesel engines, Wankel, Atkinson and Gnome engines, Jet Engines include rockets, turbojet, turbofan and turboprop, and a variety of steam engines. 










The animations are nicely done and do a great job of explaining how the engines work. 


This is a great site for pre-engineering, engineering, and science classes.

Engine Education - great resource from Pratt&Whitney on how engines work

Engine Education is a resource from Pratt & Whitney, makers of turbofans, turbojets, turboprops, and rocket engines.

The site has four different animations that explain how the different types of engines work: turbofans, rocket engine, turboprop and land based turbine engine (generates electricity).



The animations are well done and explain the concepts in a way that all students can understand.

This is a great resource for science classes and could also be used in other classes to get students interested about these topics.



Note: I worked for Pratt & Whitney many years ago in my previous life as a Aerospace Engineer.
