Research has been conducted on an extended expansion engine using a multiple linkage system to increase the thermal efficiency of general-purpose engines. Previously reported engine increased mode fuel economy by 12.9%, while generated 1.93 times the summation of inertia compared to a conventional engine with the same output power.The newly-proposed multiple linkage system operates through a longer stroke term at a crank angle of 191.6°, so both of the piston speed and acceleration become lower.The summation of inertia in the newly-proposed multiple linkage system was decreased by 46.3% compared to that of the previous multiple linkage system.
