Building an Automobile, Step 03: Cylinders Showing Piston and Crankshaft

| View Cart ⇗ | Info

“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
