Have you ever wondered how a car engine works? The modern four-stroke engine is not that different from the first motor created by Nikolaus Otto in 1876. Despite all of the technical advancements such as electronic fuel injection, direct injection, variable valve timing, and more, an engine still operates through four different steps: Intake, Compression, Ignition, and Exhaust. In order to help you understand the basics of how an engine creates power from fuel, we put together this infographic.

This infographic explains how the four-stroke or four-cycle engine works. The use of custom diagrams of the inner-mechanisms of a four-stroke engine helps lend credibility to the infographic’s claims. The simple left-to-right layout is intuitive here and easy to follow. The title, “How 4 Stroke Engine Work,” however, includes a typo, but more importantly, isn’t really answered in the infographic. If titled along the lines of “The 4 Separate Strokes of the 4-Stroke Engine,” it would be a more complete piece, but in its current state, it reads like an unfinished thought, and the reader will likely leave with more questions than they began with. Overall, we'd give this a C.
