As early as 2013, heavy trucks began the road of engine module design in order to reduce the engine failure rate. Can you say that the module design of this engine is really good? Let's take the first phone of the old editor to explain. Improve work efficiency and reduce the incidence of failures In the past, mobile phones were all detachable batteries and memory cards. Those who used them knew that the performance machine was particularly prone to failure in addition to being bulky. The memory card was easy to be stolen, the battery was easy to drop, the charging frequency was high, etc. The problem is. Anyway, there were always some accidents during the fun of the old editors, leaving a shadow of the old-fashioned student era. In turn, look at the current smart phone, battery, memory card are integrated design, both in appearance and performance are far more than the phone. In contrast, the failure of the integrated design of the mobile phone is clearly expected to decline. The modular design of the engine and the integrated design of the mobile phone have the same effect. The module design of the heavy-duty MC series engine can be much more, as follows: The oil module integrates a module such as an oil filter, an oil cooler, an oil separator, and a oil pressure limiting valve into one module. This reduces the number of sealing elements and naturally reduces the leakage failure rate. The fuel module integrates the functions of the fuel pre-filter, main filter, hand pump, fuel pressure sensor and central tube exhaust into one module. This compact arrangement also makes maintenance easier. The oil pump is a rotor gear pump, and the oil pump housing is mounted on the crankcase. This design makes the installation of the oil pump simpler and more reliable, and provides stable oil pressure. The parts mentioned above are familiar to the card friends. Don't look at these parts, but the importance is irreplaceable. Reduced number of parts and reduced engine weight According to official data from heavy trucks, the modular design has significantly reduced the number of parts by 25%. Compared to the MC11 engine , the number of components in the MC13 engine has been reduced by approximately 400. Making a small number of important parts into a module reduces the number of faults and reduces the weight of the engine itself, which is very beneficial for the ultra-strict Chinese transportation industry. The quality of the whole vehicle is light, and the goods that are pulled are more than the ones earned by the card friends. China National Heavy Duty Truck's MC series engines have many other highlights in addition to the modular design of the old series to reduce the failure rate and reduce their own weight. For example, the engine block is made of vermicular cast iron material, and the connecting rod head adopts the breaking process. Active noise reduction technology is at the leading position in China. We believe that relying on the Man Technology platform and adopting advanced technology and manufacturing level, China National Heavy Duty Truck will create the most suitable engine for Chinese trucks.
Brass forging is the same as other metal forgings, the main feature is that it can change the internal structure of the metal and improve the mechanical properties of brass. The original state of forged brass materials includes brass bar, brass ingot, brass powder and liquid brass, etc. The bar has uniform grain structure and mechanical properties, accurate shape and size, and good surface quality, suitable for demanding and mass production. Because brass has the characteristics of wear resistance, good electrical conductivity and good corrosion resistance, copper forgings are often used in marine projects, automotive machinery, communications, plumbing and other industries.
For copper forging, the main reason is that the forging temperature is relatively narrow. Usually, induction heating can be used for hot forging. However, a reasonable solution can be selected according to specific products and specific requirements. SCZY has been working in copper forging for a long time and has corresponding experience, so it can reasonably predict the processing of products.

Interpretation of the advantages of heavy-duty MC series engine modules by using "plate brick" machine
Lifting the modular design of the engine, the old editors jumped out of two scenes. The first thing that comes to mind is the MC series engine of China National Heavy Duty Truck Co. , Ltd., followed by the "brick brick" machine that accompanied the old student era - Nokia. The reason why these two irrelevant objects can be brought together is to start with the modular design.
