You might have noticed the rising availability of electric cars and hybrids. They are showing up everywhere and are touted for being eco-conscious. However, at least for now, gasoline still rules the road.

And any car that runs on gas or diesel uses an internal combustion engine. These types of engines have dominated our roads since 1858 when Jean Joseph Etienne Lenoir patented the first commercially successful one. But it wasn't till 1876 that Nikolaus Otto patented the four-stroke engine which is the form of internal combustion engine used today.

These types of engines are as popular as they are powerful. In 2019. they accounted for more than 90% of global car sales.
They have come a long way over the years and continue to evolve acquiring more green credentials as nations become more environmentally conscious.

Yet, despite the engines' popularity, many people still have no clue how they work. In this video, we take a look under the hood and explain how these powerful engines convert chemical energy into kinetic energy and what four-stroke combustion cycle is. Want to find out more? Watch and learn.
