Steamer

A steamer was motorized road vehicle whose power plant was a steam engine. Steamers burned kerosene to heat water in a boiler which turned to steam and was used to propel the vehicle. If the vehicle was parked for a short period of time, the burner was left on at a low level in order to maintain steam pressure in the boiler. Otherwise, it was shut off and it required an 8-10 minute wait for pressure to build up before the steamer could be driven.
