RESILIENTED PISTON IN THE INTERNAL COMBUSTION ENGINE

摘要

In a four-stroke internal combustion engine an elastic or telescoping link is provided between the piston crown and the crank shaft (5) whereby, at the completion of the exhaust stroke, the piston crown is able to extend its travel towards the cylinder head (2) thereby expelling substantially all combustion products from the working space (22). The link may be a compression spring (17) or telescoping members located between the piston and connecting rod (8), between sections of a multipiece piston (12, 13) or between the small end and big end of the connecting rod (8). The elastic or telescoping link has application in reciprocating, rotary or orbital piston engines.
