Inline engines- engine where all pistons are set one after the other
V type engines- as you can see here the pistons are arranged in a way that they form a v. V type engines can range anywhere from v2 to v12 and even more. (Most commonly known v type Engle is the v8)
Boxer type configuration- as you can see here the middle long oval bump is where the crankshaft would sit. The side offset protrusions are each cylinder housing the pistons along with the heads on top. (The lines accost each cylinder are called heat sinks which dissipate heat when in contact with cooler outside air.
W type engine- envision a v type engine with either another inline engine slapped in the middle of the two or one on each side of those cylinder banks (cylinder banks are the main body of the engine where all the cylinders are lined up)
Rotary type engine- a unique and somewhat common engine where instead of a piston the rotary engine uses an offset triangular shape piece and oval chamber to intake squeeze and expel gasses. The three spaces one large and two small are different stages of its revolution.
