Abstract

7822. Douglas, J. T., and Livens, F. H. April 5. Gas and explosive-vapour engines. -In an internalcombustion engine the charge is ignited by compression into an extension of the cylinder which is allowed to become heated. In the case of an oil engine, the temperature can be regulated according to the density of the oil used. When using very heavy oil the engine is started with a lighter oil. The oil flows or is sprayed through a passage D into a passage E, and is heated by contact with the heated roof of the chamber A. The carburetted air passes into the chamber A by a valve B, and is compressed into a thin cover H at the end of the chamber, which becomes heated by the successive explosions. The heat of the cap H is regulated by adjusting an asbestos cap J, which is held by a spring catch N. Pegs or ribs E<1>, G are formed on the walls of the chamber A, and the lower part of the chamber is cooled by a water jacket Q. The apparatus is enclosed in a casing 0, a part P of which can be moved aside, so that the tube H may be heated by a lamp when starting. A light oil can be admitted to the carburetter when starting by a passage just below the passage D. In the modified apparatus shown in Fig. 4, the air supply entering by the passage C passes forward along the passage C<1> and flows backward along the passage E. The carburetted air may return to the admission valve F direct by a passage E<3>, or the passage may be divided by a diaphragm E<5>, round which the mixture passes and flows to the admission valve by a passage E<7>. Liquid oil is prevented from entering the cylinder by a screen E'.
