Intense competition for Cummins natural gas engines also emphasizes price/performance

In the past, when Chinese domestic auto brands competed with foreign brands on the same stage, the most important thing was the price/performance ratio. Today, when foreign brands introduce new products, they also begin to emphasize price/performance.
On May 14th, at the 2014 Beijing International Road Transport, City Bus and Parts Expo, Cummins, the US independent engine manufacturer, launched the first domestic natural gas engine L8.9G. In the media interview after the conference, Peng Lixin, vice president of Cummins, said: "L8.9G also emphasizes cost performance. Its advantages are high stability, strong power, low gas consumption, and competitive prices."
Cummins is the first company in the world to develop natural gas technology. In the 1960s, natural gas engine research and development began. In the 1980s, Cummins's first natural gas engine for vehicles was very successful once it was launched. At present, Cummins has a total of six R&D centers working together on a global scale to jointly participate in the development of natural gas engines.
In the U.S. market, natural gas engines are widely used. In the bus market, the share of natural gas engines is 15%. In the clean truck market such as sanitation vehicles, the share of natural gas engines reaches 50%, and the share of heavy trucks in long-distance freight transportation is 1%~2%. It is understood that Cummins natural gas engine in the United States natural gas engine market share is 90%.
The use of natural gas vehicles in the Chinese market was relatively early, and it gradually evolved from CNG vehicles to LNG vehicles. In the United States, natural gas for commercial vehicle use is mainly CNG, which is mainly used in short-distance areas. According to Cummins, LNG's market is more promising as more and more large companies use natural gas engines.
Peng Lixin said that China is a country rich in oil, gas, and coal, and there is a great demand for energy. As China adjusts its energy structure, the extraction and import of natural gas is rapidly increasing. With the economic and environmental advantages of natural gas, China is becoming the world's most important natural gas engine market. According to Liu Yue, general manager of the natural gas business in the Asian region of Cummins Asia and the China bus market, in 2013, sales of natural gas trucks sold in China had already exceeded 30,000, and they are still developing at a relatively high rate.
Since 1999, Cummins has launched Cummins B Series (B5.9G) 195-horsepower and 230-hp Natural Gas Engines (CNG) in the Chinese market, and assisted Beijing Public Transport in creating three "firsts" of natural gas commercial buses. "The number one global gas bus fleet in the city", "the world's largest passenger car" and "the world's highest natural gas bus."
The performance of imported engines is high, but the prices are relatively high, and they cannot fully meet the needs of users. The local bus companies have some special requirements on the dynamic nature, reliability, and environmental performance of vehicles. RoeEast, general manager of Cummins' global medium-heavy gas business, said that it is unrealistic for engineers who are more than 10,000 kilometers away to develop products that are perfectly suited to the Chinese market. Therefore, Cummins needs to do some localized development of products for the Chinese market.
Peng Lixin said that the Cummins L8.9G natural gas engine was developed by Wuhan Technology Center. The cylinder body adopts the diesel engine block provided by Dongfeng Cummins, and then the Woodward combustion control system is installed in the Cummins plant to complete all parts and components. assembly.
L8.9G adopts the world's advanced natural gas technology R&D platform and CAE simulation simulation tool, which integrates the world's top bench testing equipment and the overall development process has been more than two years. The engine uses the unique domestic real-time analysis of gas components to enable the product to adapt to gas in different regions and has a wide range of applications. L8.9G accumulative bench test verification time exceeds 8000 hours, and in particular carried out severe thermal shock test over 10,000 working cycles, and conducted 600,000 kilometers of actual road operation test for vehicle operating conditions in China market. To ensure reliable operation of the engine under all kinds of operating conditions.
“In the past, natural gas engines were less dynamic than diesel engines. However, according to customer feedback after trial operation, the power of L8.9G is very good, which gives us great confidence.” Peng Lixin.
“The parts of Cummins L8.9G are 100% from China. We can supply small batches in June this year, and we can officially mass-produce them in July, with the capacity to produce 20,000 units per year. Its price is based on the products in the domestic mainstream market. For reference, the price must be competitive with them,” said Peng Lixin. “We hope that the products developed by Wuhan Technology Center in the future will contribute to the application of natural gas engines worldwide.”
