Explanation Graphic-How an Engine Works


To accompany my visual essay, I chose to draw a graphic explaining how an internal combustion engine works.  I chose this idea because, for one, it is familiar to me; I have always been interested in cars.  Secondly, the process that motivates our vehicles is extremely complex and I wanted to showcase it in a more simple light.

Of course, there are many processes that occur within a gasoline engine which I have not shown, but the action that gets the car going is explained in detail.  I attempted to make the drawings as life-like as possible, and I achieved this by drawing two cutaway figures so that it appears the viewer is looking into the engine.  I tried to depict the various elements as realistically as possible, especially with regard to color (coolant is green, oil is golden, and the metal composites that engine blocks are made from are silvery-grey).  I also chose to represent intake (fresh) air as blue, while exhaust was brown to delineate the difference between the two, before and after the combustion.
