• 2、Is Weifang engine Weichai

What is the difference between Class I Weichai engine and Class II Weichai engine

1. B20J1 and 4B20J2They are two different engines. The following are the main differences between them: Power: the power of 4B20J1 is higher than that of 4B20J2. The former has a maximum power of 190 horsepower and a maximum torque of 360 Nm; the latter has a maximum power of 185 horsepower and a maximum torque of 385 Nm.

2. Different torque: The detailed positioning of WP12 is a 6×4 composite transport tractor and an 8×4 heavy-duty dump truck, which makes up for the lack of torque that may occur in the 10L engine, so the torque of the two engines is different.

3. The displacement is different. P10 is 726L and P12 is 1596L. The structure of the aircraft is different. The simple point of P10 is more complex than that of P12. The horsepower is different. The horsepower of p10 is 240-375, and the horsepower of P12 is 270-570.

4. Therefore, the differences between these two models of engines are as follows: different displacements. The cylinder diameter and stroke directly determine the displacement of the engine. The so-called engine displacement refers to the working volume through which the piston moves from the upper stop to the lower stop. If the engine has several cylinders, the sum of the working volumes of all cylinders is called the engine displacement.

What is the torque of torque of the connecting rod bolt of Weichai 4100 diesel engine

The torque of the connecting rod bolt of the diesel engine is 180~201N.m. The diameter of the connecting rod bolt of a normal vehicle diesel engine is about M14~M16, and its strength level is at least 8 (up to 19) or above. For example, the 9-stage bolt of M14, its tightening torque is about: 180~201N.M.

to 170N·m. The torque of the connecting rod screw of Weichai power engine is carried out according to the standards set by the manufacturer, so its torque value should be between 150 and 170N·m.

Nm is not equal to 30 kg force, because torque is a unit of torque and kilogram force is a unit of force, and the two are not in the same category.

The two screws should be screwed to 120N several times, and then mark them to 90 degrees and add one 90 degrees. 1 The tightening moment is too large during assembly, and the force is uneven.

-9 kilograms. The fastening torque requirement of the connecting rod screw of the Chai 5 engine is 8-9 kg. It aims to ensure that the connecting rod screws can reach an appropriate degree of tightness. By correctly using the torque wrench and operating according to the specified value, it can be ensured that the connecting rod screw is installed correctly to achieve the required performance.

At this time, you can refer to the national standard of ordinary bolt fastening torque (see the table below). Generally, the diameter of the connecting rod bolt of the general vehicle diesel engine is about M14~M16, and its strength level is at least 8 (up to 19). For example, the 9-stage bolt of M14 has a tightening torque of about: 180~201N.m.

Is Weichai East China a Weichai engine?

1. East China Weifang diesel engine and Weichai are not the same thing. Weifang East China Engine Co., Ltd. is a comprehensive company integrating research and development, production, manufacturing and sales of diesel engines. Enterprise. The company was established in 2001. After the continuous efforts of East China people, today's East China Company has strong R&D and production and manufacturing capabilities.

2. No, East China mainly produces domestic models. Weichai refers to Weichai Power, and the horsepower range produced should be a little larger than that of East China, such as the TBD226 series introduced by WD615 WD618, etc.

3. No connection. Shandong Weifang East China Engine Co., Ltd. was established in 2001. Its shareholders are three natural persons surnamed Guo, all of whom have nothing to do with Weichai Power Co., Ltd.

4. Huafeng is authentic Weichai. According to the relevant public information of the inquiry, Huafeng Co., Ltd., formerly known as Weixian Huafeng Machinery Factory, was established in 1920. It is one of the earliest manufacturers of diesel engines in China and the vanguard enterprise of our domestic combustion engine profession.

5. No. Weifang engine is produced by Weifang East China Engine Co., Ltd., not by Weifang Diesel Engine Factory.Weifang East China Engine Co., Ltd. is a comprehensive enterprise integrating production and manufacturing, export trade and after-sales service.

6. It is a Weichai brand engine. Weichai is one of the famous diesel engine manufacturers in China, headquartered in Weifang City, Shandong Province. The diesel engines produced by Weichai are famous for their strong power, high reliability and good economy, and are widely used in heavy trucks, construction machinery, buses, ships and other fields.

Is Weifang engine Weichai?

No. Weifang engine is produced by Weifang East China Engine Co., Ltd., not by Weifang Diesel Engine Factory. Weifang East China Engine Co., Ltd. is a comprehensive enterprise integrating production and manufacturing, export trade and after-sales service.

East China Weifang Diesel Engine and Weichai are not the same thing. Weifang East China Engine Co., Ltd. is a comprehensive enterprise integrating the research and development, production, manufacturing and sales of diesel engines. The company was established in 2001. After the continuous efforts of East China people, today's East China Company has strong R&D and production and manufacturing capabilities.

Location: Weichai is located in Weifang City, Shandong Province, and Weifang is a prefecture-level city in Shandong Province, China. Business field: Weichai is one of the largest diesel engine manufacturers in China, focusing on the research and development, manufacture and sales of diesel engines and related parts.

A manufacturer that assembles, sells and develops diesel generator sets, and Weichai refers to Weichai Power Co., Ltd., which is a manufacturer of automotive, marine, engineering machinery,The manufacturer of diesel engines for supporting diesel generator sets produces well-known domestic brands, with good product quality, reliable performance, durable and fuel-efficient, economical and environmentally friendly.
