The small end of the connecting rod is integrated with the connecting rod, and a bronze bushing is installed in the hole, which is connected with the piston with a piston pin; The cross section of the rod body is I-shaped, which can reduce the mass while ensuring the strength and stiffness, and prevent it from twisting under pressure; The connecting rod big end is divided into upper and lower parts. The upper part and the rod body are cast into a whole, and the lower part is the connecting rod bearing cap, which is connected with the upper part by bolts. In order to ensure that the connecting rod big end can be pulled out from the cylinder smoothly, the connecting rod big end has two forms: flat cut and oblique cut. Two semicircular connecting rod bearings are installed in the connecting rod big end. In order to reduce the friction of the connecting rod journal, a layer of antifriction alloy is poured on the bearing surface. The positioning between the connecting rod and the bearing cover is generally in three forms, namely, seam, according to the tooth shape and positioning sleeve, to ensure the accurate fit of the two.
