Slow motion video captures combustion process

Warped Perception

Warped Perception

Have you ever been driving down the highway wondering what your motor is really doing thousands of times a minute?

YouTuber Matt Mikka has opened a window into the inner workings of the internal combustion engine on his Warped Perception channel.

Mikka installed an inch-thick transparent glass head onto a 3 hp flathead Briggs and Stratton engine, then set up a Phantom 4K high speed camera to create videos of the combustion process that are 150 times slower than real time. You can see the valves move, the fuel entering the chamber and the spark igniting it. For comparison, he burns gasoline, rubbing alcohol and acetylene.

Unfortunately, the last one burned so violently it wrecked the head before he could try the one he wanted to the most: tequila. But if you want to see what happens if you heat up a bottle of beer with an acetylene torch, he’s got you covered.
