ABSTRACT:
The invention relates to new and useful improvements in the design of partially constrained five-bar mechanism for use in reciprocating piston engines and compressors. The design comprises a piston and connecting rod assembly which is driven by a crank having an intervening linkage which varies the effective crank radius. The advantages of the design are in the larger swept cylinder volume which increases the air consumption rate and in the increased mechanical advantage during the power stroke. The mechanism accelerates the piston during the terminal phase of the compression stroke which improves ignition and combustion at lean limit operating conditions.
