(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 working reliability and durability of Bare Engine should not be too large due to the gap between the cranks. If the gap is too large, the lubricating oil will flow in large quantities in the gap. The working conditions of the connecting rod mechanism are related. Improper assembly of the crank-connecting rod mechanism will affect the oc

⑴The problem occurred. The surface quality requirements of Bare Engine are very strict. The pull marks on the cutting edge not only affect the surface quality, but also hang magnetism in some flaw detection processes. In order to control this defect, the equipment has to be frequently stopped during productio

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

MG Roewe Maxus Engine have irregular and complex shapes and are difficult to locate. The size heads are connected by thin rods and are easy to deform. The size tolerance, shape tolerance, and surface roughness requirements are high. The processing technology of MG Roewe Maxus Engine follows the principle of sur

Bare Engine honing refers to the use of one or more oilstones installed around the honing head, and the oilstone is opened upward along the road by the opening mechanism to press it into the hole wall of the workpiece, thereby generating a certain contact surface. At the same time, the honing head rotates and reciprocates. The parts do not move; or the honing head only rotates and the workpiece reciprocates, thereby realizing MG Roewe Maxus Engine honing.

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

A slight deformation and bending of an Bare Engine will cause the Bare Engine to fail to start. After the Bare Engine is started, the idle speed is unstable, it shakes violently, and there is a knocking sound. Secondly, use professional tools for measurement, which requires testing in a repair shop. 1. Water inflow into the cylinder

Bare Engine cylinder head screws generally require 8-9 kg, connecting rods 5-6 kg, and crankshafts 10 kg. Here are the relevant information: MG Roewe Maxus Engine are a device that provides power for cars. They are the heart of cars and determine the power of cars. Economical, stable and environmentally friendly. MG Roewe Maxus

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.

1. Rough machining stage The rough machining stage is also the machining stage before the connecting rod body and the cover are combined: it is mainly the machining of the reference surface, including the machining of the auxiliary reference surface, and the machining of the connecting rod body and the cover, such as milling and grinding of the two mating surfaces.

In the processing of Bare Engine and assemblies, the processing and positioning methods of the rod end face, the top and side of the small head, and the side of the large head are adopted. In the processing of the connecting rod cover in the process of processing the oblique joint surface from the bolt hole to the stop, the processing and

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.

As we all know, Bare Engine are the heart of cars, and Bare Engine also need small parts to ensure the normal operation of car engines. Bare Engine are one of them, and they play a vital role in Bare Engine. So why do such small things play such a big role? The following are some relevant knowledge points about

After the rollover, the oil in the oil pan flows into the air filter, intake manifold and intake port through the universal pipe of the crankcase. After the MG Roewe Maxus Engine is started, a large amount of oil is sucked into the combustion chamber. During the compression process of the piston, the pressure on the top of the piston increa

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

This situation is usually caused by continuous injection of fuel by a certain cylinder injector of Bare Engine. Often before that, there will be difficulties in starting, idling jitter, black smoke from the exhaust pipe, and power reduction. After disassembly and inspection, it can be judged by observing the co

(1) Is the air filter damp or attached to soil? Are there any water marks on the air filter housing and the intake pipe wall? (2) Check the Bare Engine oil to determine whether the MG Roewe Maxus Engine cylinder has water ingress. After the Bare Engine is flooded, the Bare Engine cylinder head is flooded, and the oil around

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

Bare Engine are rod-shaped components that connect the piston and the crankshaft. It transmits the force of the piston to the crankshaft and converts the reciprocating motion of the piston into the rotational motion of the crankshaft. The connecting rod is a slender non-circular rod with a variable cross-section. The cross-s

The connecting rod is one of the main transmission components of Bare Engine. Its function is to transmit the force borne by the piston to the crankshaft and convert the reciprocating motion of the piston into the rotational motion of the crankshaft. It is mainly composed of a small head, a rod body and a large head. T

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.

Bare Engine are the heart of cars, and connecting rods are key components of MG Roewe Maxus Engine. Connecting rods are subject to complex and changing alternating loads. Therefore, the production quality of Bare Engine directly affects the overall performance and reliability of MG Roewe Maxus Engine. Since connectin
