When Bare Engine are working, the working conditions of the crank-connecting rod mechanism are quite harsh, and they must withstand high temperature, high pressure, high speed and chemical corrosion. Therefore, the material and structure requirements of the crank-connecting rod mechanism are quite high. The forces acting on the

Bare Engine mostly use high-strength 45 steel, 40Dr steel, etc. And improve cutting performance and impact resistance through quality adjustment treatment. The hardness requirement of 45 steel is HB217~293, 40Dr is HB223~280, and ductile iron and powder metallurgy technology are used to reduce the cost of blanks. The blanks of

Bending or breaking due to problems with the connecting rod itself. This situation can generally be determined by chemical composition analysis and hardness test of the connecting rod material, metallographic structure test, scanning electron microscope fracture analysis and other methods. Low stress fatigue fracture is caus

Water enters the cylinder (combustion chamber) of an Bare Engine, causing the Bare Engine to bend or break. When the vehicle is flooded on the road, the Bare Engine will suck water into the cylinder. The water that initially enters the cylinder quickly forms hydrated gas under the action of the high t

First, install a cylinder on the Bare Engine, then wrap the piston tightly with an iron ring, and push it gently with a hammer handle. At the same time, turn the Bare Engine to near the top dead center so that the connecting rod big end can be installed and accurately fall on the connecting rod shaft. While pushing the Cummins Engi

(1) Before installation, check and confirm whether the gap between the end and edge of the Bare Engine meets the technical requirements. When installing the old ring, install the ring groove according to the original cylinder number and original order. When installing the Bare Engine, special tools should be used. (2) When installing, insta

The forms of failure are fatigue fracture and excessive deformation. Usually, the parts of fatigue fracture are three high stress areas on the connecting rod. The working conditions of MG Roewe Maxus Engine require the connecting rod to have high strength and fatigue resistance, and sufficient stiffness and toughness. The materia

In recent years, with the continuous development of the automobile manufacturing industry, the automobile and parts manufacturing industry has become the largest industry in the tool industry. Customers are important. And it is the "heart" of the car. Bare Engine also play an important role in the processing

The installation direction of Bare Engine is marked forward, which is described in detail below: Bare Engine are subject to the gas force of the piston pin and its own swing and the reciprocating inertia force of the piston group. The magnitude and direction of these forces are cyclically changing.

Most Bare Engine materials use high-strength selected 45 steel. 40Dr steel, etc., which are quenched and tempered to improve cutting performance and impact resistance. The hardness requirements for 45 steel are HB217~293, and 40Dr is HB223~280. There are also applications of ductile iron and powder metallurgy technology to reduce the cost of blanks.

This situation can generally be determined by analyzing the chemical composition and hardness test of the connecting rod material, metallographic structure test, scanning electron microscope fracture analysis and other forces. The possible reason is that the quenching microcracks lead to low-stress fatigue fracture, and there is pearlite in the organizat

Water ingress into Bare Engine causes the connecting rod of Bare Engine to bend or break. When the vehicle is driving on a road with water on the road, the MG Roewe Maxus Engine will suck water into the cylinder. The water that initially enters the cylinder quickly forms hydrated gas under the action of the high temperature of the cylinder

As a key component of Bare Engine, connecting rod processing technology has received widespread attention. With the rapid development of the manufacturing industry, many new manufacturing and processing technologies have emerged. Connecting rod cracking technology is a new type of connecting rod processing technology that appeared in the 1990s.

The blanks of steel MG Roewe Maxus Engine are generally produced by forging, and there are two forms of blanks: one is to forge the body and cover separately. The other is to forge the body and cover into one piece, and then cut it during processing or use the expansion and fracture process to expand and fracture it. In addition, in order to avoid blank defects, 100% hardness measurement and detection are required.

This situation is usually caused by continuous fuel injection from a cylinder injector of an MG Roewe Maxus Engine. Often, there will be difficulties starting, idle shaking, black smoke from the exhaust pipe, and decreased power before. After disassembly and inspection, it can be determined by observing the c

The MG Roewe Maxus Engine is a rod-shaped component that connects the piston and the crankshaft. It transmits the force of the piston to the crankshaft, converting the reciprocating motion of the piston into the rotational motion of the crankshaft. The connecting rod is a slender variable-section non-circular

1) Rough machining stage The rough machining stage is also the processing stage before Bare Engine: mainly the processing of the reference surface. Including the processing of auxiliary reference surfaces, as well as the processing after Bare Engine, such as milling and grinding of two mating surfaces. 2) Semi-finishing s

The connecting rod is a key component of Bare Engine, with a wide variety of types and huge demand, among which MG Roewe Maxus Engine have a large demand. The connecting rod is a slender variable-section non-circular rod, whose rod body cross-section gradually decreases from the large end to the small end to adapt to the rapidly

The connecting rod body is a long rod-shaped component, and the ignition of fuel will exert a large force on the connecting rod. Moreover, this force is intermittent, which brings alternating loads to the connecting rod. Under the long-term action of alternating loads, the metal materials of MG Roewe Maxus Engi

If it is found that the Isuzu Engine exceeds the regulations, remember the bending and twisting direction, and use special tools to correct it. Correcting Bare Engine at room temperature will produce elastic deformation and aftereffect, that is, after unloading, there is residual stress in the rod body, and the

Bare Engine should not be damaged, folded, or hardened by aging, nor should they be too thick or too thin, otherwise they should be replaced. When installing, the curled side should face the cylinder head. When installing a used Isuzu Engine, it must be carefully checked. If there is any damage, new parts shoul

Clean the crankshaft, especially flush the oil passages with pressure oil, blow dry with high-pressure air (or air pump), and do not leave yarn hair when wiping. Clean the main Bare Engine, and clean and blow dry all the oil passages of the cylinder block like the crankshaft. Install the bearing on the Bare Engine, apply engine oi

Do not increase the high speed of Bare Engine without authorization. Especially in the absence of a tachometer, it is very dangerous to increase the speed of Bare Engine at will. If the Isuzu Engine is found to be overspeeding (measure the tachometer or hear a scream), the Isuzu Engine should be turned off immediately,

Faced with a small Isuzu Engine with a broken connecting rod, we must be full of doubts: What is the reason for the connecting rod break? How to avoid this from happening again? The damaged Isuzu Engine function "tells" us a lot of information. Just by observing the clues on the Isuzu Engine components, we can find the culprit for the c
