Advanced Hybrid Engine Design from Michigan State University

In October 2009, MSU engineers received $2.9 million to develop a bench scale version of an advanced hybrid engine. Today, they have completed that task and are now ready to develop a full-scale version of their engine.

What makes their design better than other engines? Greater efficiency and fewer emissions. Electric vehicle engines today use a piston-style engine to produce their electricity. The MSU engine uses a “wave disc design,” which means it has far fewer moving parts, is lighter and, therefore, uses less fuel to operate and emits fewer emissions. You can read more about the engine’s technical aspects at SAE International.

Here is a diagram of how the engine operates:
