Changzhou bus experience is often talked about in the industry, and it is known as an exemplary bus, especially in the line convenience, ride comfort, clean power, etc., has long been among the ranks of domestic first-class urban public transport, Changzhou has therefore become a national Public transport will give priority to developing demonstration cities. Changzhou also led the industry in emissions control. In March 2014, Changzhou City, Jiangsu Province government issued the "Changzhou City Air Pollution Prevention Action Plan Implementation Plan." Changzhou Bus was in the national prefecture-level cities in October 2013. The first batch of "superbuses" that met the country's five emissions was launched.
In Changzhou, Superbus has won the public's love for its unique shape, special body design and good ride experience, and has also become a reference for other cities. Among them, power selection is a major feature of Superbus. It is understood that 51 out of 118 super buses are equipped with Dongfeng Cummins Engine Co., Ltd.'s National V Engine. The Changzhou bus ranks first in the country. Why did you choose Dongfeng Cummins, where is the "demonstration"?
Leading technology to meet various "super" bus standards
In terms of the selection of engine emission standards, Changzhou Bus has always been aware of "advanced". According to Zhou Pengjie, Chief of the Maintenance Division of Changzhou Public Transport No. 3 Branch, Changzhou Bus had used the Guosan engine as early as 2006, and the National IV engine has also been used since around 2008. At present, the domestic five-emission standard engine for prefecture-level urban public transport is rare, and the Changzhou bus has been able to use the Dongfeng Cummins State Five engine to play a consistent “advanced consciousnessâ€.
When the "Superbus" was tendered at the beginning, the preconditions for power selection were: to meet the country's five emissions, and to take into consideration good performance and reliability. Dongfeng Cummins Motors' five engines both assured Changzhou Bus: The reliability of Cummins engines is very well known in the industry, and Cummins is the only company with the world's only five key diesel systems (fuel system, air inlet system, filtration and aftertreatment system). , In-cylinder Combustion Optimization System and Electronic Control System, all independently designed and developed multinational corporations, which ensure the best cooperation between subsystems, optimize the performance of the engine, and maximize the coordination of the low emissions of electronically controlled engines. And the Cummins III, IV, and V emission engines are derived from the same basic platform development and are of strong heritage. When upgrading to the national V standard, it is only necessary to adjust the injection pressure of the fuel system. The upgrade of the electronic control system can be achieved. Ensure the reliability of the engine.
At present, there are many brands on the market that have developed the products of the State Fifth Group and have laid out the layout of the State Five Market in advance. There are many brands, but not every one can meet the requirements of Changzhou Bus Superbus. "The standard number of seats for the Superbus is 21+1. It is rated to carry 60 passengers. Although it has a length of 7 meters, it has reached the loading capacity of 9 meters. It is a medium-sized public transportation vehicle with strong loading capacity. Therefore, the vehicle's power requirements are extremely high.†Zhou Pengjie said, “Dongfeng Cummins State V Engine not only meets the requirements of Changzhou Public Transport in terms of emissions, but also has a high power ratio and a compact structure to meet the power required by the Superbus. Matching requirements, this is one of the key reasons to choose Dongfeng Cummins's five engines."
Reliable, durable and well-behaved customer praise
The advantages of hardware and software are the basis of a good engine, reliable and easy to use to satisfy users. As a product that has already been used and verified in European and American markets, the actual use of Dongfeng Cummins' five engines has completely eliminated the initial concerns of everyone.
It is understood that Superbus's daily itinerary is approximately 200 kilometers, and the longest line on the single-lane runs back and forth for 40 kilometers. Different roads, frequent gear shifts, acceleration, deceleration, parking, and start-up require high engine reliability. Jiang Xinhua, director of the Changzhou Public Transport Third Branch Warranty Plant, said: “Each time we replace a new car, we are most concerned about the reliability of the engine. Because once the engine problems, the entire car can not run, directly affecting the entire line Dispatch, and the country five engines are new technologies, new products, we have more and more worried.†According to Jiang Xinhua, this time selected the Dongfeng Cummins State five-engine superbus, so far has not happened because of engine failure affect the operation of the situation , Dozens of engines, like the usual engine most likely to occur in the leakage of oil spills have not occurred, the drivers have also consistently reflected the "Kang machine is very good." However, the use of certain other engines of the same type often causes the phenomenon of insufficient power soon after use, which causes great troubles for on-duty drivers and operations.
At the scene, we also talked about the supply of the country’s five oil products. We learned that Dongfeng Cummins’s engine has specifically developed a “three-stage fuel filtration system†to better protect the fuel injection system. This is even a fuel-efficient fuel system. Water and impurities can also be filtered out in time, which solves a problem that many users are facing.
Reducing fuel consumption by 100 kilometers can save about 5%
For bus passenger transport companies, fuel costs are one of the company's major expenditure costs and account for 30% to 40% of total costs.
In Changzhou bus, the fuel consumption is linked to the driver’s salary. The high fuel consumption directly affects the driver’s salary. “Some pilots can get seven or eight hundred rewards for saving fuel, and some drivers may even be fined seven or eight hundred yuan because of high fuel consumption.†Zhou Pengjie said, “Each driver is concerned about fuel consumption. This is also an important criterion for our consideration of the engine."
In terms of fuel economy, Cummins has several advanced fuel-saving technologies and uses BOSCH's most advanced fuel electronic control system to achieve precise control of fuel injection. At the same time, in order to optimize the matching between the vehicle and engine, Dongfeng Cummins' product application engineers carried out a large number of tests and analysis work according to the common working conditions of Changzhou Bus, and adapted and adjusted the engine so that the common operating range of the engine was always located in the economic fuel consumption area, which fully guaranteed the fuel economy. Sex.
Due to the differences in the weight and passenger capacity of the summer air-conditioner and superbus, the fuel consumption data under different conditions are not comparable, but Zhou Pengjie estimates for the reporter that the fuel consumption of the Superbus using Dongfeng Cummins Five is approximately 100 kilometers. Can save about 5%.
Service-first system sounds to bring worry-free operation
A year ago, as the “water tester†of Dongfeng Cummins’ five-country domestic market, Changzhou bus concerns about its service guarantee were inevitable. A year later, the actual situation of Dongfeng Cummins completely abolished the concerns of Changzhou bus.
Changzhou Bus has its own maintenance company, but since the Dongfeng Cummins State's five-engine technology is relatively advanced, the strong support of Dongfeng Cummins' after-sales service is essential in the short term. In response, Jiang Xinhua, Changzhou bus service manager responsible for service and training, told reporters: “Before this batch of super buses arrived, Dongfeng Cummins’s technicians conducted systematic and professional training on our drivers and maintenance personnel. After the purchase, Dongfeng Cummins's after-sales staff will visit every branch of Changzhou Bus for a few days to understand the use of the engine and solve problems."
During the interview, the driver who just happened to come back from the car was discussing the use of the machine with Mr. Xue, who visited the Dongfeng Cummins Changzhou service station. Everyone was kind and cordial, and he had become a friend-like relationship. The reporter had a simple conversation with Xue, and found that Manager Xue was fully aware of the driver’s vehicle usage, who had problems with the car at any time, how to solve the situation, and the current results. Manager Xue told reporters: “Dongfeng Cummins has always been the concept: the product has not arrived, the service first, and taking into account the small amount of new product social holdings, easily lead to weak spare parts and services, but also developed a special spare parts and service support For example, we have five spare parts that are specially stored for Changzhou bus.â€
It is understood that Dongfeng Cummins currently has more than 1,000 authorized service providers nationwide, and is pushing forward the reserve of the national, national and national five-engine spare parts in the first-line market, so that genuine spare parts can be closer to users, and can be the first time in repairs. Effectively shorten user waiting time and provide efficient and professional services.
See how advanced a company is, and see how well his partner is leading. On the green bus route, Changzhou Bus dared to take the lead in the world and chose to cooperate with Dongfeng Cummins. One step ahead and one step ahead. Centralized Feeding System
