Yuchai Engine Test Non-road country three, car engine country four, country five, country six ... From 2010 to date, Yuchai people are fighting for emission escalation. The 42-year-old Lin Tiejian went to the Engineering Research Institute for 12 years and has experienced the research and development process from the country three to the country six. He said that the current domestic environmental protection pressure is high. From Europe five to Europe six, the amount of particulates emitted is directly reduced by half, and the limit is very strict. Although the national standard of six countries has not yet been announced, but from the current situation, the country six is ​​certainly much stricter than the European six.
Difficult road to independent research and development
Yuchai Guoti Diesel Engine R&D has completely subverted the previous product platform, starting from scratch. In the fully competitive market of the engine, entering a blank field is like a minefield. All carelessly lost. In particular, after the wrong selection of the engine's technical route, it not only means a lot of waste of manpower and material resources, but also the time and cost paid is almost impossible to make up for.
On the road to exploration, Lin Tiejian believes that in order to reduce emissions, in addition to adding post-processing, it is necessary to first lower the emission of the engine's main body. This requires first adjusting the combustion strategy. However, in China's internal combustion engine industry, engine combustion and engine NVH (noise, vibration, and vibration roughness) are considered by most people to be a "mystery." It means that people cannot fully understand the process of its occurrence, climax, and demise, let alone control it. Therefore, Lin Tiejian proposed to carry out the adjustment of the burning strategy. In a simple and simple word, it is full of inexpressible technical barriers and difficulties.
Cutting-edge technology leads the industry
Yuchai's six-engine product plan is divided into six models of the light, medium and heavy three major platforms of 10 models, power coverage of 100 to 560 horsepower. Their common feature is the integration of the most advanced international engine technology with the same displacement, strong power, low fuel consumption, excellent emissions, low noise, light weight, small size, high reliability and long life.
The birth of the six new products developed by Yuchai at the same time as world-class companies is a manifestation of confidence and strength for Yuchai. It is a strong driving force for the industry and means that Yuchai will continue to lead the future. National six times. Nowadays, Yuchai’s system is constantly improving and improving. The product spectrum is continuously shrinking, power is increasingly concentrated, fists are becoming more and more powerful, and the competitiveness of products is greatly enhanced. Yuchai’s internationalization process has moved forward again. Stride.
In Yuchai’s eyes, the product development of S6 and T4 is only a microcosm of Yuchai’s development process. It shows that Yuchai can make the best products in the world’s most advanced manufacturing field.
In the Sixth National Age, Yuchai must not only lead the domestic internal combustion engine industry, but also have the right to speak in the international internal combustion engine industry.
At the Yuchai Fast Manufacturing Base, a fast manufacturing team with an average age of less than 28 years old is also using superior skills to contribute to the development and manufacturing of the company's six new products. Rapid manufacturing technology has enabled moldless rapid casting technology to be applied to key components such as cylinder blocks, cylinder heads, and various types of complex pipes. This has reduced new product development time from 120 days of original mold manufacturing to more than 40 days now.
