The implication is that, why do you think you have a latecomer advantage? What is the difference between you and the first entrant?
Chen Wei, the product director of Anhui Cummins Power Co., Ltd. (hereinafter referred to as Ankang), who has been engaged in product research and development for many years in Detroit Diesel and General Motors, and has been a chief engineer for many years in Cummins , has a wide enough field of vision and deep enough accumulation. The interpretation of Ankang's "different" information is quite large.
Chen Wei, Product Director, Anhui Cummins Power Co., Ltd.
The concept is different. "The problem in the road test is fortunate."
Backed by a century-old store like Cummins, in the eyes of many people, the advantage of Ankang is naturally technology. However, in Chen Yin’s opinion, such a judgment is correct, but it is not comprehensive enough.
After all, in the field of power equipment for 100 years, the power and economy of Cummins products have advantages. Compared with these, Chen Yu believes that reliability is its biggest competitive advantage.

“Cummins has a professional that has existed for decades, namely reliability engineering. It predicts the rate of repairs when the product is put into production and maturity according to customer needs, and has quantitative indicators, and has a specific development process to verify this indicator.†He told Reporter, the difficulty of this project lies in quantification. At present, there are still few engine companies with this capability. "To give quantitative indicators requires a set of methods, involving historical data, new product variable analysis, failure mode analysis, etc. With such a goal And the process, it is possible to provide reliable products that users are satisfied with. At present, Ankang is also building reliability engineering capabilities."
Another level of user trust in the reliability of Ankang products is integrity. “When it comes to doing it, what is promised, it must be. For example, the product data we publish is 100% verified and will not give an unverified data,†he said.
With such a concept support, it is not difficult to understand when it comes to user road testing, "discovering problems is worth celebrating." More than 10 Jianghuai trucks equipped with Cummins, which started road tests last year, have traveled more than 100,000 kilometers in the hands of end users. Starting in the third quarter of this year, Ankang will also increase the road test of the Beta prototype. “Usually we have to do two rounds of road tests for Alpha prototypes (manual prototypes) and Beta prototypes (production line prototypes), because although the suppliers of the two may be exactly the same, due to the small batch size of the Alpha prototype, it may not be possible to identify the mass production. For the Beta prototype, we require the production process, mold, and inspection methods to reflect the mass production status, and it is installed on the production line, which can identify the reliability problems that may occur in the actual production process. It is not concealed that many problems have been collected in the user road test. “It is worth celebrating when it is found to be invalid, because only when it is put into production can you avoid problems that you have never seen before, and greatly reduce the reliability risks that customers have to bear.â€
The process is different, it is not easy to say "can"
Paying attention to reliability is actually a tradition in North America. The investment of hundreds of thousands of dollars in heavy trucks needs to be fully valued. In North America, it is common for Cummins heavy truck engines to continue operating after 1 million miles of overhaul, which requires high reliability and long service life. After coming to China, the situation has changed. The requirements of Chinese truck users are fast and low-cost maintenance. Different requirements, Cummins' VPI process is also improving and optimizing.
VPI, the introduction of value package, is to control the quality of the product during the product design and development process through strict process control. Cummins' VPI process has evolved over the decades and continues to be optimized for new markets and applications. Therefore, Chen Hao will have such a view: with the database and technical standards and called Cummins three core competitiveness, is the process.

The introduction of these core competencies has made Ankang different. “Products are issued in three stages: D, L, and P. Among them, D is the detailed design state, L is the small batch production state, and P is the mass production state. All three states require long cycle and different conditions (laboratory, whole). Experimental verification of the car and the user's real road use." He told reporters that many companies said that "this version of the calibration can be issued", in the Cummins process is likely to be just a "detailed design version", "for us, It is impossible to issue the system verification to the customer without completing the system, because there is still a series of work to be done according to our process requirements. “For example, emission, according to the regulations, do WHCC cycle twice, and pass the Ministry of Environmental Protection’s verification. "Pass", but this is far from verifying compliance.
Chen Wei said that it is necessary to "pass the emission compliance certification under the Cummins standard. "We will control all possible risk points in the development process, and repeatedly verify the different market environments for different power applications to identify and Solve possible post-processing system failures, deterioration, etc. In addition, we artificially introduce systemic errors such as sensor deviation or drift, in addition to the use of standard national fuel, it also uses fuel with severe sulfur content, which fully evaluates the market. The risk of non-standard fuels ensures that even in the complex system of the National Sixth, users will not have compliance risks during use."
Different technologies have different reasons for reason
Because it is different, it is different. In the Chinese market, Cummins is a maverick. In the context of the mainstream six-phase EGR route, Cummins chose a non-EGR route. “For Cummins, who has extensive experience in the application of Euro 6 and US EPA 2010 emission technologies, the challenge for the country is not the technology itself. The real test is the contradiction between the market environment and the content of regulatory monitoring. Considering the complex market conditions in China Risk of failure rate, we chose a non-EGR technology route." Chen Yu said.
Making this choice "is not only a way to reduce costs, avoiding the risk of failure, but also based on the confidence that Cummins Smart Control 2.0 can achieve dynamic closed-loop control. Cummins made a pre-research 3 years ago to compare EGR and non-EGR technology routes Judging that the closed-loop control capability of the high-efficiency SCR control strategy can meet the requirements of the national six regulations, and will have multiple advantages in performance, fuel economy, and especially reliability. In the future, the national product route of Ankang will continue this choice." Say.

In addition to the well-known non-EGR route, maverick is also manifested in many ways.
The design indicator for the National Six Fuel System is another example. The Euro 6 practice is a high injection pressure of 2,200 bar, and most domestic products are 2000 bar, while Cummins' six- and four-cylinder machines are 1800 bar. This choice avoids the high cost and high noise of the high injection pressure system, and the power consumption of the oil pump accessory greatly affects the economical problem. Being able to do this is based on Cummins' ability and confidence in combustion optimization. At present, it seems that Cummins 4-cylinder six products have obvious advantages in noise.
On the crankshaft material, the domestic four-cylinder machine usually uses forged steel, while the Ankang 4.0L machine uses cast iron, which significantly reduces the cost. In fact, the use of low-cost cast iron materials is the embodiment of design capabilities. The Ankang National 6-liter machine has a maximum torque of 730 Nm. The cast iron crankshaft design has passed all intensive verification tests.
In the sixth phase of the country, there will be more different Ankang products, such as the available in-cylinder braking and start-stop technology.
In 2019, it has a different meaning for Cummins and Ankang. As Chen Yu said, for the 100-year-old Cummins, he believes that it will have a 200th anniversary and a 300th anniversary because of "reliability." For the half-year-old Ankang, he believes that under the empowerment of the parent company, Ankang will be like it. The name is as good as luck.
