Three main methods by which the national fuel of this country, coal, may be used for internal combustion engines were dealt with at the conference at Swansea arranged by the Internal Combustion Engine Group: the conversion of coal to gas by small portable producer plants; the injection of coal dust directly into the engine; and the use of coal gas supplied in compressed form at the gas works. The first group of papers, besides giving an account of the present position of producer gas propulsion for road vehicles in this country and on the Continent, and some results obtained in service, deals with factors in the design of portable producers and the choice of suitable coals. A report on the development of the coal dust engine in Germany was to have been given by Dr.-Ing. Hans Wahl of Germany, but was withdrawn a few days before the meeting. Informative contributions on this subject are, however, included in the discussion. The second group of papers reviews the prospects of the application of compressed gas for road vehicles and marine purposes, and also deals with marine producer gas plants and the use of coke oven and blast furnace gas for power generation.
