Abstract
THE summer meeting of the Institution of Mechanical Engineers was held in Cambridge last week. Among the many papers read and discussed, that by Prof. Bertram Hopkinson, of Cambridge University, takes a prominent place; the subject of the paper was a new method of cooling gas-engines. The most important peculiarity of the gas-engine, that which determines the characteristic features of its design and operation, is the heat-flow from the hot gases into the cylinder walls. About 30 per cent, of the heating value of the fuel passes into the metal of the engine in this way. The method hitherto employed in removing this heat has been by the circulation of water in jackets, except in the case of small air-cooled engines. In large engines, the piston and exhaust valve have also been kept cool by circulation of water. The appliances necessary for the carrying out of this method have been responsible largely for the great weight and cost of large gas-engines.
