汽车发动机连杆的弹性改造研究

论述了用高弹性应变率高强度材料将连杆制成易于产生弹性弯曲而缩伸的形式 ,使排气更干净 ,进气更充分 ,小进气量时压缩比更高 ;在做功行程的起始点 (上止点 )时降压储能 ,增加推动曲柄的切向分力 ;上止点后释放能量 ,提高对曲柄的推动功率 ;分析了连杆弹性弯曲折断和弯曲干涉的可能原因 ,并有针对性地提出了防止折断和防止干涉的可行办法

Elastic Transforming Research of Engine Connecting Rod in the Automobile

With the material of high elastic tangibility and high strength, the connecting rod is manufactured in the form of producing elastic wind and contraction and expansion easily. It makes exhaust cleanly and intake fully. The compression ratio is higher when entering gas amount is small. It makes lowering pressure, storing energy and increasing the tangent component to push crank. The energy is released after making function upper stop to push crank beneficially. The possibility of the connecting rod elastic wind breaking and wind interference is also analyzed. The practicable method to protect breaking and interference is put forward directly.
