Product Description

Pistons are parts that reciprocate in the cylinder block of an automobile engine. The basic structure of the piston can be divided into top, head and skirt. The top of the piston is the main part of the combustion chamber, and its shape is related to the selected combustion chamber form. Gasoline engines mostly use flat-top pistons, which have the advantage of small heat absorption area. There are often various pits on the top of diesel engine pistons, and their specific shapes, positions and sizes must be adapted to the requirements of diesel engine mixture formation and combustion.

The main points of the assembly of the diesel generator piston connecting rod group are as follows:
1, Press-fit connecting rod copper sleeve. When installing the connecting rod copper sleeve, it is best to use a press, or with the help of a vise, do not use a hammer to hit hard; the oil hole or groove on the copper sleeve should be aligned with the oil hole on the connecting rod to ensure its lubrication
2, Assemble the piston and connecting rod. When assembling the piston and connecting rod, pay attention to their relative position and direction.
3, Cleverly install the piston pin. The piston pin and the pin hole are interference fit. When installing, put the piston in water or oil and heat it evenly to 90℃~100℃. After taking it out, put the pull rod in the appropriate position between the piston pin seat holes, and then install the piston pin coated with organic oil in the predetermined direction. Into the piston pin hole and the connecting rod copper sleeve
4, The installation of the piston ring. When installing piston rings, pay attention to the position and sequence of the rings.
5, Install the connecting rod.
