Yuchai: Gas Bus Power Pilot
At the end of 2012, the 2013 launch of new products, Yuchai launched 12 new engine models at a time, including 7 natural gas engines, namely YC4DN-50, YC4GN-50, YC6JN-50, YC6GN-50, and YC6LN-50. , YC6MKN-50 and YC6KN-50 series, have reached the national V emission standards, the product uses a lean burning, electronically controlled full-closed loop technology, power coverage 120 ~ 440 horsepower.
In 2011, Yuchai sold 12,000 units of natural gas engines and exceeded 20,000 units in 2012, maintaining its leading position in the industry. Among them, Yuchai Bus Gas Engine sold more than 18,000 units in 2012, with a market share of 45%, ranking first in the industry. In the first quarter of 2013, Yuchai Bus's gas engine sales have also exceeded 5000 units, which occupies an absolute monopoly position for passenger car gas engines. Zhou Chuanwu, deputy general manager of Yuchai Sales Co., Ltd., said that in 2013, Yuchai's passenger vehicle sales of gas engines will exceed 30,000 units.
Weichai: HPDI engine fills the gap
On March 13, 2012, Weichai Power Westport New Energy Engine Co., Ltd. released China's first high-power cylinder high pressure direct injection compression-ignition natural gas engine (HPDI engine). This technology combines the advantages of diesel engines and gas engines, and avoids their shortcomings. It has enabled natural gas engine technology to leap from the era of ignition to the compression ignition era. This is a major change in the field of natural gas engine technology.
Recently, four series of natural gas engines from Weichai have successfully obtained the ECER 49-05B1 Euro IV certificate issued by Russia's GOST, which not only indicates that the quality of Weichai natural gas engines has been recognized by Russia's most authoritative certification bodies, but also lays a foundation for the company to further open up the Eastern European market. The foundation.
Heavy Truck: Cooperative products with Mann at the end of the year
Since mass production began in 2010, the sales of CNHTC's natural gas engines have doubled each year, and CNHTC's natural gas vehicles have spread throughout the country, particularly in Shanxi, Shandong, Hebei, Northeast China, Xinjiang, Ningbo, Xiamen and Qingdao. The export performance is equally good. The market mainly includes Thailand, Malaysia in South East Asia, Chile in South America, etc. Among them, the heavy truck natural gas heavy truck's market share in Thailand's natural gas heavy truck market reached nearly 70%.
Heavy-duty truck T12 series 380-horsepower natural gas engine is a new generation of electronically controlled, lean-burn, natural gas engines jointly developed and developed with the United States EControls company, with completely independent intellectual property rights and with the advanced level of the contemporary world. In addition, the natural gas engine jointly developed by Sinotruk and Man will be at the end of this year.
Shang Chai: H series low gas consumption
Shangchai highlighted its H-series engines at the recent Nanjing Bus Show. The Shangchai H series natural gas engine adopts a reliable and mature imported gas device. The electronic control unit collects the engine's natural gas inlet pressure, temperature, atmospheric conditions, engine speed, water temperature and other operating parameters to accurately control the injection volume of natural gas. Closed-loop correction of the air-fuel ratio based on the measured values ​​of the wide-area oxygen sensor is reflected in the test of the same conditions for the entire vehicle, which is 5% to 15% less than that of the domestic similar engine.
In addition to the matured D-series natural gas engines, Shangchai also developed 10-series E and 12-liter E-series products, covering 280 to 480 horsepower, and fully satisfying the power demand of large-scale domestic and international buses, long-distance and tourist buses.
Xichai: Low-carbon economy boosts sales
Recently, Xichai LNG Power won the bid for 40 orders from Linyi, Shandong, for its advantages of environmental protection, energy saving and low maintenance costs. Low carbon and economy have made Xichai natural gas engines hot. Taking Shandong as an example, public transport companies such as Binzhou Bus, Dongying Bus, and Taian Bus have successively used Xichai natural gas engines in batches, and have been fully recognized by customers with low gas consumption, low noise, strong power, and efficient after-sales service, becoming low in Qilu Earth. One of the first choices of carbon eco-friendly buses.
Take CA6SF2-23E4N2 as an example, Xichai LNG engine adopts the most mature American EControls gas control system, EOL production management system and fault diagnosis instrument to meet the market demand for natural gas engine batch production and after-sales service; natural gas flow control adopts electronic pressure Regulator (EPR) technology and air-fuel ratio closed-loop control strategy can save more than 30% of fuel cost per hundred kilometers.
United Power: 6K13N has the largest displacement
The joint power YC6K13N engine is currently the largest gas engine with the largest displacement and the largest torque. It has low gas consumption, strong power, high reliability, low noise, and environmental protection. The machine is based on the leading domestic 6K12 diesel engine redesigned and developed, with a displacement of 12.939 liters, which solves the problems of insufficient natural gas heavy truck torque and poor climbing acceleration performance. It integrates the internal cylinder brake and safety performance of the entire vehicle. Upgrade; a lot of optimization design, such as the use of Nikki natural gas engine nozzles.
Dongfeng Nanchong: Dongfeng Gas Engine Production Base
In May 2012, the 30,000-capacity capacity building and LNG filling station project of Dongfeng Nanchong gas engine in Phase 1 was started, and its positioning as a Dongfeng gas engine production base was determined. The total investment of the project is 150 million yuan, which will be completed by July 2013, including three aspects: integration of group resources (including Dongfeng commercial vehicle 4H, Dongfeng shares ZD28, Dongfeng Cummins 6CT, etc.) to form a series of NG gas engine products; Commercial vehicle 6105 and 6400 engine production lines were transferred to Nanchong production; Dongfeng Nanchong's NG engine manufacturing and R&D capabilities were enhanced through the addition of key equipment.
