Chongqing Chengzhihao Technology Co., Ltd. (hereinafter referred to as "Chengzhihao"), as an outstanding enterprise in the field of foreign trade export of automobile engines and engine accessories, it

On February 28, 2025, in order to further enhance the company's team cohesion, demonstrate the team spirit of unity, mutual assistance and progress, and at the same time enrich the cultural life of employees and relieve the tension and fatigue of recent work, Chongqing Chengzhihao Technology Co., Ltd. (hereinafter referred to as "Chengzhihao") successfully held an outdoor team building activity with the theme of "Spring Outing, Building Team Dreams Together". The event was held in Nanshan Kuye, which attracted the active participation of all employees of the company.

On March 10, 2025, Mr. Wu Mengneng, Chairman of Chongqing Chengzhihao Technology Co., Ltd. (hereinafter referred to as "Chengzhihao"), personally visited the engine assembly plant to understand and learn about the production, quality inspection and other processes. The upgraded production line has greatly improved its automation and intelligence level, and can provide more flexible and efficient customized solutions according to the different needs of customers.

The support part and support material directly determine the vibration performance of Bare Engine, which are generally supported on the frame through the support on the body and the flywheel housing or the gearbox housing. The support methods of Bare Engine generally include three-point support and four-point support. In modern ti

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

As we all know, Bare Engine are the heart of cars, and small parts are needed in Bare Engine to ensure the normal operation of Bare Engine. It plays a vital role in Bare Engine, so why does such a small thing play such a big role? Here are some knowledge points about Bare Engine. The connecting rod is a slender non-circular member

With the increasing severity of energy problems, from the perspective of reducing fuel consumption, cars need to develop into light vehicles, among which Bare Engine and light vehicles have become an issue that cannot be ignored in the development of automobiles. Considering the lightweight of Cummins Engine, its main compon

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

The connecting rod is a key component of Bare Engine. There are many varieties and huge demand, among which Bare Engine have a large demand. The connecting rod is a slender variable-section non-circular component, whose rod body cross-section gradually decreases from the big end to the small end to adapt to the rapid changes in dynamic loads

Rollover causes the connecting rod to bend or break. After the rollover, the oil in the oil pan flows into the air filter, intake manifold, and intake pipe through the general pipeline of the crankcase. After the Cummins Engine is started, a large amount of oil is sucked into the combustion chamber. During the compression proces

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

The fuel injection system of Bare Engine is abnormal, causing the connecting rod to bend or break. This situation is usually caused by continuous fuel injection from the cylinder injector of the Cummins Engine. Usually before the phenomenon of difficult starting, idle jitter, black smoke from the exhaust pipe, power reduction,

(1) Is the air filter damp and attached with soil; are there water marks on the air filter housing and the intake pipe wall. (2) Check the Cummins Engine oil to determine whether there is water in the Bare Engine cylinder. After the Bare Engine enters water, the oil around the Bare Engine cylinder head and exhaus

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

The connecting rod is a rod-shaped component connecting 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 member with a variable cross-section. The cross-section of

Bare Engine must not damage the cylinder gasket. Wrinkles or aging and hardening, and cannot be too thick or too thin, otherwise it should be replaced. When installing, the side with the rolled edge should face the cylinder head. When installing the used cylinder gasket in an Cummins Engine, it must be carefully

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

Clean the Bare Engine, especially flush the oil channel with pressure oil, blow it clean with high-pressure air (or air pump), and do not leave yarn hair when wiping. Clean the main bearing seat, clean and blow the cylinder body of the Cummins Engine. Install the bearing seat, apply oil, close the bea

(1) Prepare qualified connecting rod assembly and piston, Bare Engine and retaining ring, check the gap between Bare Engine and connecting rod copper sleeve, Bare Engine and Bare Engine hole, and whether the excess is appropriate. (2) Put the piston into water and heat it. After the water boils, heat it for 5~8
