Diesel-Engine Installation in Coaches and Trucks 390159
ALTHOUGH the torque variation of a diesel engine is somewhat greater than that of a gasoline engine, the difference is not serious at full load, Mr. Fisher explains. But, because the roughness of a diesel can become quite objectionable at no load, it is necessary, he says, to suspend the engine in such a way that its torque impulses cannot be transmitted freely to the chassis.
Mr. Fisher discusses the various problems of diesel-engine installation in coaches and trucks, outlines the theory of flexible engine installation, considers the special requirements of the half-dozen auxiliary systems, and describes a number of diesel installations which have proved successful in service.
The engine with which the paper is concerned is the General Motors two-stroke diesel, manufactured in 3-cyl, 4-cyl, and 6-cyl models of 82, 110, and 165 hp, respectively.
