Excerpt from Modern Engines and Power Generators, Vol. 5: A Practical Work on Prime Movers and the Transmission of Power Steam, Electric, Water, and Hot Air This Volume deals with marine engines, and turbines for motor ships and motor boats. At present shipbuilders have not arrived at the use of internal combustion engines beyond small oil or petrol engines for small craft, and that mostly for pleasure and sporting purposes. The steam turbine remains the most modern type of marine engine of any considerable power, and for high speeds. The combined reciprocating and turbine steam engine may prove suitable for smaller powers and lower speed vessels carrying cargo, especially in conjunction with steam superheaters. And a similar combination of an internal combustion engine with cylinders and pistons and a turbine utilising the exhaust gases has been proposed, and described; it promises well for marine propulsion. In fact, marine engineering is at present in a transitory state, leading to the internal combustion of the fuel and the abolition of steam and its generators.
