Yuchai Bus Launches 5D Technology

Zhong Yuwei, deputy general manager of Yuchai Machinery Co., Ltd., appeared on the May 12 launch of Yuchai bus upgrade power conference. He had just arrived in Beijing the day before and participated in the press conference in the morning. He had to travel to Hubei in the afternoon and travel to Wuhan, Shiyan and Xiangfan. For Zhong Yuwei, who shoulders heavy sales and planning tasks, such a tight schedule is already a common practice. He often travels and runs markets to understand the needs of the market, OEMs and end-users.

As an internal combustion engine expert, Zhong Yuwei after the role transformation can well transform professional advantages into sales and planning assistance. It is precisely because of the understanding of products and technologies. In the face of numerous reporters' questions, he can not only explain the problems thoroughly, but also explain Yuchai’s product advantages and technical characteristics in a simple and easy-to-understand way. At the 2011 Beijing Bus Show, Zhong Yuwei accepted an interview with a press conference and elaborated on Yuchai’s five-dimensional technology.

Two-stage booster technology, hybrid powertrain

Yuchai’s strength in the passenger car market is beyond doubt. Since 2001, Yuchai has led the passenger car market for 10 consecutive years. In 2010, it sold 111,000 passenger car engines and accumulated sales of 633,000 units, which accounted for more than 60% of the passenger car market. Share; In the passenger car market of more than 10 meters, the number of possessions reached 350,000 units. Yuchai bus power has been adhering to the concept of serving customers in market segments for many years. At present, there are a total of 9 series of 10 kinds of diesel, gas and hybrid products, which fully meet the needs of 6 to 8 meters of bus and passenger car power.

This time, Yuchai launched a five-dimensional exclusive technology that will fully upgrade passenger car power and create more value for users.

The five-dimensional technology includes two-stage supercharging technology, hybrid powertrain, intelligent power system, electronically controlled auto-calibration technology, and application integration technology. Among them, two-stage booster technology has successfully solved the dynamic contradiction between the high and low rotational speeds of road passenger engines. In 2009, Yuchai completed two-stage supercharging technology, using a small supercharger at low speed to meet the acceleration performance of low-speed vehicles; a large turbocharger intervenes at high speeds to improve the power of high-speed diesel engines and improve high-speed Power performance, thus solving the contradiction of the dynamic nature of high-low speed road passenger vehicles.

Yuchai is a leader in hybrid powertrain technology. In 2010, the Yuchai hybrid powertrain sold a total of 400 sets. Starting from the research of the single-axis parallel hybrid scheme started in 2005, Yuchai hybrid power has been doing additions ranging from providing single engines for hybrid buses, to providing hybrid systems, to the development and production of interventional motors, to intervening batteries. Management strategy, to jointly develop AMT, Yuchai can provide customers with comprehensive hybrid power system solutions.

Electronically controlled automatic calibration technology and application integration technology

Subdivision is the core concept of the Yuchai bus power market. This ability to meet the needs of different market segments stems from the development process of Yuchai's products. According to reports, Yuchai's product development process is: typical operating conditions acquisition - typical load spectrum acquisition - combustion development for performance - control strategy based on simulation results - electronic control calibration for user needs, this development process It was decided that Yuchai Bus Power could continue to meet the needs of market segments.

On the one hand, the rich road database established for many years provides the data foundation for Yuchai's customer segmentation needs. On the other hand, the engine electronic control self-calibration technology adjusts products to meet customer needs and achieves differentiated product supply. The core “soft” strength of Yuchai Bus Power.

In order to make the host plant match the Yuchai engine more simply and efficiently, in 2011 the Yuchai engine integrated "economizer switch + electromagnetic clutch fan + saver filter + heat shield, protective cover + air conditioning compressor + harness optimization + double parallel generator +Hydraulic fan hydraulic pump + cushioning cushion" integrates a variety of designs, processes, and configurations to make the most core power system the simplest and most straightforward application.

Intelligent power system

The highlight of this year's Beijing Bus Show is the various intelligent management systems launched by the automaker. Yuchai, an independent engine company, has also launched a similar product. This is the Smart Remote Management System. This system was originally called the E butler. According to reports, the system can provide functions such as abnormal reminding, fault diagnosis, fuel consumption statistics, maintenance management, and driving behavior management. Zhong Yuwei told reporters that the original reason for doing this product was to serve well. The original user had bought the car. During the three-guarantee period, Yuchai did not know the use situation. He only waited for the user to take the initiative to go to the service station and the service was in a passive state. With this system, you can understand the condition of the vehicle from the beginning of your purchase. You can actively contact the user through the background to provide services such as maintenance reminders and remote fault diagnosis. The initiative is greatly enhanced and the product is available throughout its life cycle. service.

In addition to the intelligent remote management system, Yuchai also launched the EIS, an electronic engine intelligence system. According to reports, the system has been built over five years, including an intelligent fuel economy system and an intelligent and worry-free system. It has many functions such as fan control, air conditioning control, oil detection, and filtration detection.
