inertia force , the connecting rod should have sufficient strength and rigidity , also should try to reduce their quality of connecting rod , In order to reduce the effect of the inertia force . The body of the connecting rod are generally adopts Ishaped cross section shape from big to small and gradually bee smaller . In order to guarantee the quality of each connecting rod engine running balance , the same engine cannot too big difference , therefore , the connecting rod parts , head arranged at both ends to unbalance mass of the convex block , In order to weighing after resection of unbaiance mass . Both sides of both ends of connectric distribution in the cross section . Taking into account the clamping 、 placing、 handing and other requirements , the connecting rod , head (basically the same size ). Oil holes are arranged on the connecting rod at the top (or tank ), w
