"Crankcase with crank-shaft and fly-wheel added. The crankshaft serves the same purpose in an automobile…

"Cylinders showing piston in place and connected to crankshaft. Gasoline vapor is exploded in the cylinders. This pushes the piston down, and as the piston is connected to the crankshaft it starts the crankshaft turning. The piston and the rod that connect it to the crankshaft are just like the feet and limbs of any one riding a bicycle." -Bodmer, 1917

"The magneto gives an electric spark, which explodes the gasoline in the cylinders. The water pump keeps water flowing around the cylinders to prevent them from getting too hot. This water comes back to the pump through the radiator at the front of the car. Wind blows through the radiator and cools off the water. The tire pump on up-to-date cars is run by the engine. It does not pump except when the gears, which are shown in the picture, are pulled together." -Bodmer, 1917
