| | Steam car Summary |
 | | The resulting pressurized steam is then transferred to an engine, where it is used to push a piston; a crankshaft is used to convert the reciprocating motion of the moving piston into rotary power that can be used to turn lathes or other machine tools, or, as in Cugnot's application, to propel a vehicle. |
 | | This stored energy, high pressure steam, is used to push a piston back and forth, which, through a linkage of a piston rod and a connecting rod, turns the crank shaft. |
 | | With the smoothness of the steam power and because of its phenomenal torque at only one or two rpm's the steam car's engine was typically connected directly to the rear axle, because no clutch or transmission was needed. |
