Optimizing Design Of Single Cylinder Diesel Engine With Rocking And Reciprocating Mechanism

For many years engine researchers and development specialists have appreciatedthe benefits offered by performing engine development and testing on single cylinderengines. Author wish we could improve engine by applying the rocking and reciprocat-ing mechanism to the single cylinder internal-combustion engine .The main research contents of this dissertation are listed here:(1)This dissertation first introduces the rocking and reciprocating mechanism andanalyses quick return mechanism in engine. The chief research content is indicated.(2)Through kinematics analysis we find that the rocking and reciprocatingmechanism is a quick return mechanism. Later we succeed in designing an optimizedmechanism by using simulation technology, whose angle of extreme position is 16°.So its exhaust and compressing process become faster than its intake and expandingprocess. This characteristic of the new type of mechanism can improve combustibilityin engine.(3) After resolving the interference between components during the piston's move-ment, we have designed each component for the new type of mechanism.(4) Through dynamic analysis for the new type mechanism we can get data aboutsliding block's position, velocity, acceleration and force. We find the new type ofmechanism can change the time of piston impingement. The cylinder pressure at thetime of piston impingement is smaller than the original mechanism's. Thischaracteristic can make piston move smoothly and reduce the noise from pistonimpingement.(5)For the limitation of research's time, we only finished the experiment for theoriginal engine.(6)Finally, all main conclusions and further research suggestions are given.
