Suck, squeeze, bang, and blow – there is no way to more succinctly describe the combustion process of a four-stroke engine. If you are more of a visual learner though, we might have the perfect video series to show the combustion process in your typical road-going motorcycle.
The video comes courtesy of the “Warped Perception” channel on YouTube, which has made a name for itself by taking high-speed high-resolution cameras and using them to show and explain complex actions.
In the case here, Warped Perception took a 3hp Briggs & Stratton engine, removed the head and replaced it with about an inch of acrylic glass, and then proceeded to see what would and would not burn in the simple engine design.
Slowing things down to 4,000 frames per second, and shooting 4k video, we get an absolutely stunning, not to mention informative, perspective of what happens in your typical internal combustion engine. Enjoy!
