Endurance test casts high quality, high reliability products on the diesel engine

Before the Shangchai engine was delivered to the factory, in addition to the three high-level experiments outside, many experiments were carried out in the laboratory. Such as durability, reliability and other experiments. Among them, the durability test of the engine is the most important, and it is the most important verification link in the engine development process. Because, in the durability experiment process, you can find various defects in the design, materials and processing of the engine, provide rectification advice for the design, improve the overall performance of the engine, and can initially determine whether the engine life meets the quantitative requirements.

However, durability experiments require long-term investment and costly consumption. Taking the W series engine as an example, in the Shanghai Diesel Endurance Laboratory, the W series engine placed on the rig needs 300 hours of continuous operation, a total of 1000 hours of endurance test, and the relevant engineering machine and technician continuously record the rotation speed. Related data such as torque. Just for fuel, a laboratory costs nearly 30,000 yuan a day. Durable experiments take 1,000 hours, and in nearly 42 days, fuel costs have reached a million.

It can be said that the manpower, material resources and financial resources required to complete the durability experiment are enormous. However, Shangchai has always been at the expense of experimental support. Shangchai Power Product Manager added: “The cost of the experiment is huge, but we always guarantee that each product will undergo strict durability verification before it is put into the market. Only in this way can we provide users with efficient, reliable and reliable products.".

Equally important to engine durability testing is reliability testing, such as indoor cold start. The cold start experiment of Shangchai is usually carried out in the hottest July and August, in preparation for the winter cold test. Shangchai conducts a cold start experiment in summer and an alpine experiment in winter to ensure that users do not have any problems during winter use.

The cold start experiment was carried out in a specific environment, and the tester placed the engine in a constant temperature of 25 degrees for the entire night, nearly 12 hours. On the second day, the engine was taken out and placed directly in the hot summer day. For such a demanding experiment, the team leader of Shangchai said: "Only through such a harsh environment can the engine's low temperature start reliability be checked. And provide a real data reference for determining whether to change the design or improve the system. It is worth mentioning that in the cold start, the upper limit of the engine can reach 38 degrees, which is an extreme test.

Strictness towards oneself is the responsibility of the customer. Any factor that can affect the quality of the engine product, Shangchai Power has done a thousand experiments, the purpose is to ensure that each engine is of high quality, durable and in line with national standards, in line with customer needs. product.
