See-through engine lets you watch the combustion process

Warped Perspective has constructed a special clear head to give you a special look inside their Briggs and Stratton L-Head single cylinder engine.

Using a super slow-mo 4K HD camera they show how the combustion process looks under both rich and lean conditions.

For this experiment they’ll swap the fuel type between isopropyl alcohol and gasoline.

Take a look inside your engine with this sweet video.
