label: Description
content: The model represents a reciprocating engine of more or less conventional steam engine design in which the operating fluid is vaporized carbon disulphide supplied by a boiler or generator and condensed in an air-cooled condenser. The transfer of heat from the fire in the boiler to the carbon disulphide and from the exhaust vapor to the cooling air of the condenser is effected through water. Plumbago, or black lead, is used to protect the walls of the generator and the engine from the action of the carbon-disulphide vapor. Steam and hot water from the water jacket of the generator are led into passages surrounding the engine cylinder and connecting pipes to prevent the loss of heat form the vapor.
