Trunk Piston Engine

 

an internal-combustion engine without a crosshead. It differs from a crosshead engine in that the lateral stresses that arise in the crank gear are absorbed by the working surfaces of the piston and the cylinder. Trunk piston engines, which include all high-speed internal-combustion engines, are used in tractors, automobiles, and motorcycles.
