| 摘要 |
The present invention relates to reduction of compression space and improvement of intake / exhaust efficiencies through structural modification of a booster cylinder that delivers an explosive exhaust pressure generated during an exhaust stroke of one cylinder in a multi-cylinder internal combustion engine to an intake pressure of another cylinder, to minimize frictional heat and abrasion due to the reciprocating motion of a piston of the booster cylinder, and to ensure a damping force by an air pocket when the piston of the booster cylinder moves towards the exhaust side. The apparatus for connecting intake and exhaust valves for internal combustion engines according to the present invention comprises: a plurality of cylinders such that when one cylinder is on an exhaust stroke, at least another cylinder synchronously performs at least part of an intake stroke; a pressure delivery pipe for connecting an exhaust manifold of one of the plurality of cylinders to an intake manifold of another cylinder; a booster pump installed in the pressure delivery pipe, wherein the booster cylinder, in which the piston of the booster pump is reciprocally and movably embedded, is comprised of a head having a first through-hole communicating with the intake side of the pressure delivery pipe and a recess for reducing the compression space as the piston moves towards the intake side, and a body fixed to the head, the body having a second through-hole communicating with the exhaust side of the pressure deliver pipe. |
