1893 Description of a portable engine designed for burning liquid fuel on Holden's system. 'A cast-iron baffle plate, protected with fireclay, is used to prevent the direct impact of the flame on the tubeplate of the boiler. The grate when using oil is covered with lumps of broken firebrick and limestone, small quantities of coal being also introduced at intervals. Very littlesmoke and no sparks are produced when liquid fuel is thus burnt, and the fireman’s labours are greatly reduced, as the oil or tar is automatically fed to the the furnace by an injector.'
