The engine connecting rod is an important part of the engine, and
its structural characteristics are:
The small end of the upper end of the connecting rod is connected
to the piston pin, and the big end of the lower end is connected to
the crankshaft, which can convert the reciprocating movement of the
piston into the rotational movement of the crankshaft. It is just
like the movement of your thighs when riding a bicycle. Connecting
rods are generally made of medium carbon steel or alloy steel
through forging, machining and heat treatment. Because the
connecting rod is subjected to the cyclical force of compression,
tension and bending when it works, it is required to have as small
mass as possible, but also sufficient rigidity and strength. If the
rigidity is not enough, it will cause the big head hole to be out
of round, and the bearing bush will be burned due to poor
lubrication ; The bending of the shaft will cause air leakage and
oil blow-by in the cylinder.
The big end of the connecting rod is generally made of two
semi-circular blocks, one is the lower end of the big end of the
connecting rod, and the other is called the connecting rod cover.
The two are screwed together with connecting rod bolts. These two
pieces are processed together (boring). The surface of the big hole
is very smooth in order to closely match the bearing bush. The
surface is also milled with grooves for positioning the bearing
bush and small oil holes.
The working conditions of connecting rod bolts are the same as
those of connecting rods. They are generally made of high-quality
alloy steel or high-quality carbon steel, which are forged or
cold-headed. When installing the big connecting rod, the connecting
rod bolts must be tightened according to the torque specified by
the factory, and measures must be taken to prevent loosening by
themselves. The connecting rod bush is made of two halves like the
big end of the connecting rod. The base of the bush is thin steel
plate, and the inner surface is cast with a wear-reducing alloy
layer such as babbitt alloy. The anti-friction alloy has the
function of reducing friction, accelerating running-in and
maintaining oil film.
The surface of the bearing bush and the connecting rod head and the
connecting rod cover must have a very high smoothness. Before the
bearing shell is installed, the half of the bearing shell is not
semi-circular. When it is installed, the bearing shell can be close
to the wall of the large-head hole due to the pressure
(interference). In order to prevent the bearing bush from rotating
or axial displacement during operation, the positioning bosses are
punched on the bearing bush to be respectively embedded in the
grooves of the big head and the connecting rod cover. There are oil
grooves on the inner surface of the bearing bush to ensure good
lubrication.

FAQ
Q: We can see from the pictures why the color of our products is
darker than ordinary affiliates?
A: That ’s because our pistons are high-silicon and high-nickel, so
the color will be darker.
Q: What are the benefits of high silicon and high nickel?
A: We can refer to their performance, we can know that high silicon
and high nickel products have better lubricity and higher quality,
so their service life will be longer.
Q: In addition to this advantage, does your product have any other
highlights?
A: There are also more cooling pipes inside our pistons to
facilitate better heat dissipation and make the product last
longer.
Q: I want to know how your after sales service
A: I forgot to tell you that our after-sales service is perfect,
and we will have someone to deal with problems encountered by
customers to ensure you have the best shopping experience.
