Cummins and Scania Jointly Develop Ultra-High Pressure Fuel Injection System (XPI) With the 0.1 mm electrolytic wire under pulsed discharge, on average, every 30 seconds, a high-pressure common-rail injector nozzle completes the processing and production. Today, Cummins fuel system is based on such production speed, stepping up the expansion of the Chinese market.
The Cummins Fuel System, established in 2007, has so far had a decade of development in China. Thanks to the rapid advancement of emission upgrades in recent years, the sales of Cummins fuel systems jumped rapidly from 50 million U.S. dollars in 2014 to 140 million U.S. dollars in 2016.
“Continual escalation of domestic emission standards is undoubtedly the biggest driving force for Cummins fuel systems.†Tang Haocheng, general manager of Cummins Fuel Systems (Wuhan) Co., Ltd., said that since the fourth quarter of last year, the domestic commercial vehicle market began to recover, coupled with the Emissions standards are about to be fully implemented, and it is expected that Cummins Fuel Systems will achieve sales of US$200 million this year. â€
Meet market demands to maximize local production
The rapid development of the Cummins fuel system in the Chinese market has not only benefited from the rapid increase in emission standards. In Tang Haocheng’s view, the significant improvement in the quality of oil products, coupled with strict supervision by the government, is also a result of Cummins’s fuel system being able to “strengthenâ€. The guarantee. It is reported that Cummins fuel system in the medium and heavy engine market share from 1% in 16 years, quickly increased to the current more than 10%.
Kirin injection system
For the engine, precise control and superior performance are prerequisites for meeting higher emission standards. Zheng Fengming, director of sales and marketing services for Cummins Fuel Systems, said that Cummins Fuel Systems has been developing injection systems with higher injection pressures and more precise control. A set of reliable injection system can not only bring good performance to the engine, but also reduce the design difficulty and burden of exhaust gas after-treatment system.
17 years ago, Cummins and Scania jointly developed the Ultra High Pressure Fuel Injection System (XPI). In 2007, the XPI system achieved an injection pressure of 2400 Bar. After three years, this parameter reached 2600 Bar. In terms of design, the XPI system has a non-leakage design of the fuel pipeline, so that the pressure in the fuel pipeline is more constant, so that the engine is in a ready-to-go state. This design can also achieve a certain degree of energy saving effect. Not only that, according to Zheng Fengming, the XPI system also has full life cycle self-learning and compensation capabilities. After the fuel injection system and the engine body are worn out, the fuel injection timing and fuel injection timing are corrected to ensure the entire life cycle of the engine. Guaranteed efficient power and performance within.
Cost and performance are irreconcilable contradictions. Cummins Fuel Systems is focusing on cost considerations while introducing advanced technologies into the Chinese market. “Cummins always pays attention to meet the needs of the target market.†Tang Haocheng stated that in the process of product development and promotion in the Chinese market, Cummins fuel system meets the needs of domestic users in terms of supply chain, R&D, and services. He introduced that, especially in the research and development of the S6 emission standard fuel injection system, many of the key R&D work was completed in China. It is reported that Cummins Fuel System (Wuhan) Co., Ltd. is the only fuel system business unit in the world that Cummins has at the same time has the ability to research and develop, produce, test and verify. While continuously introducing advanced technologies, Cummins fuel system will maximize local production.
In the impression of many people, the high-pressure common rail injection system is inconvenient to repair, and it is necessary to replace the assembly components to resolve the fault and the maintenance cost is high. "As Cummins Fuel Systems continues to increase its market share in the Chinese market, we will also launch a low-cost after-market service program." Tang Haocheng said that since the end of last year, Cummins Fuel Systems has started to launch remanufactured fuel systems in the domestic market. Accessories. It is reported that Cummins remanufacturing fuel injection products is the core business of Cummins in North America, and Cummins will use the model of the North American market in the future to introduce more competitive products and eliminate the worries of end users.
Pay attention to the integration ability and constantly expand the application range
"As a part of Cummins, we understand the need for the Cummins engine's injection system." Tang Haocheng said that most Cummins fuel systems were previously equipped with high-mass and heavy-duty engines with a displacement of 8.9 liters or more. At present, this model is undergoing a transformation. From the standpoint of business development in the Chinese market, Cummins fuel injection systems are continuously expanding their application development. The 6-liter medium-sized engine has become the focus of Cummins fuel system development.
“The Kirin injection system that we put on the market this year will be applied on the Tata Cummins ISB series engines in India.†Tang Haocheng stated that this is the first time that Cummins fuel system has entered the medium-sized engine injection system in the world. It is reported that with the implementation of the BSES-IV stage emission standards on April 1 this year, the demand for fuel injection systems in the Indian market will increase significantly. The "Kylin" fuel system produced in Wuhan is expected to achieve 4 to 60,000 sets this year. The output will reach 12 to 140,000 sets of production scale next year.
In January of this year, Cummins integrated its existing electronics business unit with the fuel system business unit. The integrated electronic fuel business unit will focus on R & D and production of engine ECM control and fuel injection systems as the core components of the engine. Cummins fuel injection system will be in the future. Will have a competitive strategic advantage.
