ABSTRACT:
An engine heater for airplanes or automobiles burning propane gas to heat the engine. The heater employs electrical power to control the combustion of the propane gas and to propel the heated combustion products toward the engine. The unit may utilize a building's usual line current of 115 volts a.c.; it may also rectify this a.c. voltage to provide d.c. power capable of charging the battery on the vehicle. In the absence of the 115 V. a.c., the heater may simply connect to its own battery or the battery of the airplane or the automobile in order to warm the vehicle's engine and battery to facilitate the commencement of the vehicle's operation. The heater unit includes connections to the appropriate source of power for the heater's operation. When connecting the 115 volts a.c. source, it transforms the voltage to the appropriate magnitude to operate the heater. The unit may also include a gas pilot light, an ignition coil for the pilot light, and two electrically controlled valves. The first valve permits the passage of propane to the pilot light while the second valve allows the passage of the propane to assure the proper functioning of the unit. Without a source of electricity to assure the proper functioning of the unit, both valves close and prevent the escape of propane.
