Cummins Revelation (1): The smooth implementation of Guoliu cannot rely solely on the engine component

On July 1, 2019, it was the key node for some provinces and cities in the country to take the lead in implementing the national six emission regulations. On the same day, Cummins Centennial Tour and Cummins Sixth Technology Conference was held in Wuhan, China. The event demonstrated Cummins' core technologies to meet the National 6th B and Euro 6D phases.

From the proposal to the implementation, the implementation of the National Sixth Standard has experienced several delays, and today some provinces and cities have set up the transition period of the National Six, which has extended the time node for the actual implementation of the National Sixth. The reason is no, the most strict in history. The harsh emission regulations are actually more difficult to implement than imagined.

It was once thought that technology is the most difficult part to solve. Nowadays, from the quality of oil products to the matching degree between engine parts and OEMs; the change from national background to the environmental protection trend has affected the smooth implementation of Guoliu to varying degrees.

Fully responsible for Cummins ' engineering and technical work in various fields in China Cummins Global Vice President Dr. Peng Lixin is particularly clear about this point. He said: "The smooth implementation of Guoliu cannot and cannot be done by simply making the engine parts work. It needs all aspects of cooperation. Cummins, as an engine manufacturer, is willing to use our efforts to promote its smooth and smooth implementation."

Most worried: oil quality affects product performance DPF stability and research Cummins is always doing

As we all know, DPF is an important technical component of the sixth phase of the country, and oil is the most influential factor in the DPF operation process.

Dr. Peng Lixin admits that the quality of oil is one of Cummins' most worried about the current implementation of the country.

Cummins research found that 90% of the oil extracted from Sinopec, PetroChina and CNOOC's gas stations can meet the requirements of Guoliu for oil products, but the problems in the actual operation of the users are not consistent with the inspection report obtained by Cummins. . In 2017, Cummins began pumping tests in the user's fuel tank. The oil quality rate of 80 fuel tanks from all over the country was only 9%.

The price difference between compliant and non-compliant oils and the data between compliance and non-compliance rates bring products into reality in an idealized state. The results of the survey made Cummins-related leaders understand that only product compliance does not meet the safe, stable, and fuel-efficient power products that Cummins wants to bring to users.

To solve this problem, Cummins started with both technology and research. First, the Cummins DPF has already used more than 3 million units, 10 billion hours, and 375 billion kilometers. These data bring the high stability of its products and the increasing service emergency response capability during use.

In response to the various problems of various products in the sixth phase of the country, Cummins has provided service guarantees for users from five aspects: 2000+ authorized service outlets, forward-looking cyclic service training; exclusive DPF global service experience; remote intelligent service management platform 24-hour service commitment; APP quick access to expert diagnostic services.

In addition, Cummins sent its own investigation report to the Ministry of Environmental Protection. The Ministry of Environmental Protection launched actions such as blackening and blackout stations in April 2017. By October, the 9% pass rate in the user's fuel tank had risen to 60%.

Dr. Peng Lixin said: "The effect is very significant, but it is not enough. We will always pay attention to the oil quality problem and do what we can, and will continue to improve the stability of our products, so that it will be further reduced by other factors."

Most hope: Guoliu should be an overall improvement of the system of an industry sector

Guoliu is not a simple concept, nor can it be completed when the data meets the requirements. Guoliu is a double-edged sword. It is affected by various factors and also releases energy to influence all parties. Therefore, the upgrade of Guoliu should be a comprehensive upgrade of the system in an industry sector.

From the iterative upgrade design of non-EGR non-exhaust gas recirculation to the Wisdom Brain 2.0 version, an intelligent system can control the engine and all component subsystems in a closed loop, so that the engine performance can be integrated and improved, no longer obvious. "The board", extended to the sixth phase, Cummins can provide customers with a complete set of powertrain solutions, including the powertrain with AMT automatic transmission, and low-cost high-performance e-shift intelligent assisted shifting system. Both the AMT gearbox and the e-shift assisted shifting system are safer and smarter, providing customers with higher performance, lower fuel consumption and a more comfortable driving experience.

These are the work that Cummins needs to do as an engine component producer. As a multi-power solution provider, Cummins needs to work closely with the OEM as a helper. At the event site, Dr. Feng Jing, deputy dean of Futian Automobile Research Institute, said: "Futian and Cummins team work closely together to complete the demand planning of Guoliu Power, define product characteristics, and segment the market such as express, cold chain, green pass, etc. The application analyzes the characteristics of the working conditions, according to the road spectrum information acquired by the big data platform, through the cloud platform and simulation software analysis, adjusts and optimizes the engine data and the transmission system matching; during this period, both parties jointly complete the calibration of the vehicle emissions of the National Sixth Power , power test, idle speed test, parking regeneration temperature test, cooling system test, hot and cold start test, and vehicle driving calibration optimization, power / maneuverability verification under extreme conditions, and finally achieved Accurate docking of industry users' deep customization needs."

From Futian to Dongfeng, Shaanxi Automobile... Cummins has a full-fledged partner in China, which makes its engine products closely match the needs of trucks, and it also enables users to get more demand for the country from big data.

From the demand product - product development completion - product matching attempt - user experience feedback collection, and user experience feedback collection are included in the demand, Cummins stretches several arms above the national six full chain, will be related to the country six The system is linked together to make the problem more clear and clear, and to make the resolution more efficient and effective.

The smoothness of Guoliu cannot rely solely on the engine parts, but the importance of the smooth implementation of this component by Guoliu is not necessary.
