“Our company's order growth in June was mainly due to the rapid growth of gas engines. The sales in the first six months have been the same as last year and the previous year. It is estimated that the sales of gas engines will also increase this year.†Jiang Yanxian, deputy general manager of the Jinan Power Department, told reporters.
In fact, the rapid growth of gas vehicles, especially LNG vehicles, is not only reflected in the jump of figures, but its application range has also begun to expand into multiple subdivided areas, and has been rapidly gaining ground in some areas.
From CNG to LNG
Li Tongsheng, Minister of Culture and Sports of Zhongtong Bus Brands, mentioned two trends when talking about the passenger car market this year: “This year, gas vehicles sell well, and there is a trend to develop from the original CNG to LNG, showing the trend from CNG to LNG. The trend of change.†Feng Xingfu, deputy general manager of Beijing Public Transport Group, made it clear at a conference in Nanjing that more than 3,000 buses planned to be renewed this year will all be LNG buses, and in order to guarantee the application of these LNG buses, it is expected that It is also necessary to build 30 to 40 LNG skid-type liquid filling stations.
Another trend is that the demand for hybrid bus passengers is beginning to tilt towards gas-electric hybrids. “Last year's hybrid buses sold on the market were mostly hybridized with oil and electricity. However, from the end of last year to the present, gas-electricity mixing has become the main choice in many cities. As for gas-electricity hybrid selection of LNG or CNG, it is mainly from the economy and overall. Consider the use of cost.†Li Shengsheng said that the Zhongrong Electric Hybrid Bus is currently sold in many areas and cities such as the eastern coast, southern China, northwest, southwest, etc. The gas station layout in these areas is also more reasonable.
According to Li Bingzhi, deputy manager of China National Heavy Duty Truck Products Department, LNG vehicles have four characteristics: First, high safety, LNG ignition point is 650 °C, higher than gasoline and diesel; LNG explosion limit is 5% to 15%, - LNG vapors above 106.7°C are lighter than air, and they will volatilize and scatter as soon as they leak. It is difficult to form a concentration that is explosive in the event of fire. Therefore, neither LNG nor its vapor will explode in an unenclosed environment. Second, the lower self-weight, LNG storage pressure is generally less than 1.6MPa, far lower than the storage pressure of CNG, thus avoiding the potential danger of CNG due to the use of high pressure containers, but also greatly reduce the weight of the container itself. The third is more economical, and the mileage is higher. After natural gas is liquefied at low temperature, its density is more than 600 times that in the standard state, and the volumetric energy density is about 72% of that of gasoline, which is 2 to 3 times that of CNG, and therefore it is equivalent to fuel. In terms of volume, the cruising range of LNG is 2 to 3 times that of CNG, which is comparable to gasoline vehicles. The fourth is environmental protection. Before natural gas liquefaction, it must undergo rigorous pre-purification. As a result, the impurity content in LNG is much lower than that of CNG, which creates favorable conditions for automobile exhaust emissions to meet more stringent standards.
Most of Shandong 210 diesel passenger trains are LNG vehicles, and there are more than 30 CNG vehicles. Deputy Chief Engineer Wang Guoxun told the reporter: “The CNG vehicle was purchased with gas at the time. It is more convenient for CNG to be gas-filled with LNG than for LNG, but the mileage for CNG vehicles is not as good as LNG vehicles.â€
Of course, not all regions are more inclined to LNG vehicles. “Now Xinjiang now sells natural gas vehicles for LNG and CNG, especially in southern Xinjiang. PetroChina and Sinopec built two LNG production plants there. Together with Xinjiang Xinjie, they have arranged many LNG and CNG refueling in southern Xinjiang. "The Xinjiang liberation heavy-card dealer Wang Fang (a pseudonym) said: "Now Xinjiang's CNG products sell better than LNG because there are more CNG refueling stations. But a CNG vehicle needs more than 10 high-pressure resistant cylinders." The weight of the car has also increased."
Expanded use area
"The natural gas heavy truck market has four major characteristics: First, rapid development, 2012 is a year of rapid development of natural gas heavy truck market, the growth rate is close to 100%; Second, the base is low, only about 3% of the total sales of heavy trucks; Third, the prospects The wide demand for emission upgrades, the low-carbon environmental protection features of gas vehicles, and the continuous improvement of gas station layout all indicate that the outlook for natural gas vehicles is broad. Fourth, competition in the future natural gas heavy truck market will intensify, Li Bingzhi concluded.
From the perspective of the use of gas vehicles, it is also gradually expanding. According to reports, at present, LNG vehicles have been sold in 31 provinces across the country, and their application range is also expanding. “The use of LNG heavy trucks has expanded from tractors to common dump trucks, cement mixers and mining dump trucks. This is a new trend.†Duan Hengyong, deputy general manager of sales department of CNHTC, said that the use of LNG vehicles The scope is expanding.
The good economic performance has led to the continuous expansion of the LNG vehicle's application field from the initial road transport, and this has led to new business opportunities. Valin Xingma spotted this opportunity. On May 22, Valin Xingma signed a cooperation agreement with Furuizhuang. The two parties will jointly develop LNG (liquefied natural gas) automotive industry equipment and application products to form a close cooperative relationship with the strategic supply chain. According to Liu Hanru, chairman of Hualing, as early as in 2006, Hualing Xingma had already developed a CNG heavy truck, but due to the immature market development environment, Hualing did not invest much effort in this market. In recent years, with the development of gas filling stations and the advantages of natural gas heavy trucks becoming more cost-effective, Shaanxi Automobile, China National Heavy Duty Truck, FAW Jiefang, Futian and other companies have moved and emerged rapidly in this market, and Valin Xingma will follow suit this year. The development focus is locked in the LNG market.
However, it is not easy to compete in the LNG market that has already become a strong player. Liu Hanru uses its own competitive advantages in special vehicles such as heavy trucks and concrete mixers, and looks at the expansion potential of LNG trucks in the field of special vehicles to bring natural gas The breakthrough of heavy trucks is locked on LNG mixers and mining vehicles. He believes that these two market segments have not yet been conquered, so from this perspective, Valin Xingma only needs to focus on the product, less interference from competitors, and the winning side will increase.
Liu Hanru's strategy did bring rewards to him. Since this year, Xingma Special Purpose Vehicle has swept the market downturn since 2011 and ushered in another period of rapid growth. In May, it achieved sales of 911 units, a record growth rate of 176.9. %, sales growth in the single month in the industry; from January to May, sales of 2,906 vehicles, a cumulative increase of 58.8%. In the analysis of the reasons for such achievements, Valin believes that seizing the LNG special-purpose vehicle market and launching a full range of LNG mixer products is a major contribution to this major move.
“Now there are many LNG vehicles in the area of ​​hazardous chemicals transport vehicles. For example, tankers that transport natural gas are mainly looking at the construction of local gas stations. If conditions are met, they will choose because LNG vehicles are environmentally friendly.†The relevant personnel of the marketing department said that.
Recently, Liuzhou Wuling's first five-meter gas passenger car and the era of Yuling's “oil and gas dual-use fuel micro-cards†have appeared one after another. They have also expanded the application fields of natural gas vehicles, and have extended from large passenger cars and heavy trucks to the field of mini-vehicles. At present, Wuling's two NG (gas)/gasoline dual-fuel buses are also under development and are expected to be available in July this year. In terms of time, according to reports, from January to May 2013, the era of Yuling dual-use fuel micro-cards sold 2,600 units, the results can not be overlooked.
