ABSTRACT:
A compression spring coupling is provided between the engine piston and the crankshaft in a four cycle, reciprocating, internal combustion engine. This spring, when extended to the full extent permitted, is held compressed by a force equal to the piston force required to compress the fuel mixture for proper combustion under no load or very light load. Under no load on the engine the spring acts as a stiff coupling between the engine piston and the crankshaft. At heavier loads the spring is resiliently compressed in proportion to the load. The engine displacement is substantially smaller at no load and light loads than under heavy loads.
