Is the natural gas vehicle advocated by Xiong Weiming, the general manager of Shanghai Diesel Engine Co., Ltd., occupying a place in the application of new energy vehicles? Shang Chai is trying to change the embarrassing situation of blooming inside the wall and outside the wall.

The wave of new energy is being staged for more than a year. Abandoning high fuel-consuming products and moving towards small-displacement and new-energy vehicles, the target seems to be very clear. Who will be the hybrid, biofuel, and electric vehicle? The direction of the future development of the car, the state's policy so far has not been as clearly defined in other developed countries which kind of new energy vehicles, perhaps to give the market the freedom to choose a rare opportunity.

“Natural gas vehicles are more environmentally friendly energy fuels than hybrids and diesel vehicles.” Even so, what bothered Xiong Weiming, general manager of Shanghai Diesel Engine Co., Ltd., was that the domestic market had less knowledge of natural gas engines and the media’s propaganda for natural gas. It is also far inferior to other new energy sources. Shangchai's natural gas engine also suffers from an embarrassing situation of blooming walls outside the wall. With the help of the Asia-Pacific Gas Vehicle Organization’s China Tour and Shangchai Power Environmental Protection Tournament recently launched in Shenzhen, Shangchai launched a new attempt.

It has been 10 years since the Shanghai Diesel Power entered the R&D of natural gas engines. For the past ten years, Xiong Weiming was very pleased that Shangchai's natural gas engine products successfully entered the Thai market.

As fuel prices have risen, the Thai public has turned to lower-priced natural gas vehicles. At present, there are 155,000 vehicles in Thailand that use NGV natural gas. Thai cars use natural gas to increase their daily demand to 3,900 tons, and about 100 vehicles are converted to NGV daily.

Four years ago, Shang Chai saw the huge demand in the Thai market and started to develop. Up till now, they have signed a contract for 5,000 vehicles with Thai partners.

In fact, due to the abundance of resources and the large price gap with oil, the Southeast Asian market has become the main battlefield for natural gas vehicles. LeeGiokSeng, chairman of Asia-Pacific Natural Gas Vehicle Organization, said at the forum that natural gas vehicles in the Asia-Pacific region have experienced 40% high growth for 5 years. According to John U37324X, chairman of the Natural Gas Automobile International Association, predicts that by 2020, 80% of the world's automobiles will use natural gas as a power source.

Natural gas accounts for only 2.5% of China's energy consumption, far below the world average (25%) and also below the Asian average (8.8%).

The coastal areas in South China represented by Shenzhen and Shenzhen have a unique advantage. In the LNG imported from Australia and many countries in Southeast Asia, the first batch of receiving stations established the coastal areas in Shenzhen and South China. This is also the Asia-Pacific Gas Vehicle Organization in China. Touring and the launch of the Shangchai Power Environmental Protection Tour will set Shenzhen as one of the reasons for China’s first stop. This event, similar to the Olympic Torch Relay, starts from Iran, passing through China, Malaysia, Thailand, Singapore, Indonesia, Vietnam and South Korea. Southeast Asian countries. In addition, Shenzhen is an intermediate site between Southeast Asia and China, and is actively promoting natural gas vehicles. More advanced LNG vehicles have also been put into trial use. “The development of LNG (liquefied natural gas) vehicles in coastal cities has become a trend,” Xiong Weiming said at the forum.

Sulfur and lead are not included in the exhaust gas of natural gas vehicles. Compared with gasoline vehicles, its carbon monoxide emissions are reduced by 80%, hydrocarbon emissions by 60%, and nitrogen oxide emissions by 70%. In addition, natural gas fuels can effectively reduce the operating costs of automobiles. Shanghai Diesel Power saw this trend as early as in 1998, starting with diesel and natural gas dual-fuel engines to improve technology. After the dual-fuel engine was gradually eliminated by the market in 2003, the development of a single fuel injection single-fuel engine was put on the agenda. At this time, Shanghai Diesel Engine Co., Ltd. began to localize some non-key components.

“In the past five years, the Shanghai Diesel Engine was obscure. At that time, the domestic infrastructure and related parts and components industry was not perfect. Users were unaware of the electronic control technology and were skeptical about domestically-controlled natural gas engines. Beijing and Shanghai represented The developed cities mainly use imported natural gas engines.” Dr. Liu Kai, Product Manager of Shangchai Product R&D Center, talked about his personal experience in these years. The situation has changed in the past five years. The firewood has accumulated a lot and is gradually recognized by many public transportation users, such as Yinchuan and Chengdu. , Shijiazhuang, Xi'an, Jinan, Shanghai, etc.; in the field of heavy-duty trucks, they have won the championship; in the export market, they are also far ahead.

"Shangchai natural gas engine has an absolute advantage in the domestic matching ratio of similar products, and it is in the leading position in the market," said Liu Kai.

Expected policy support

LeeGiokSeng believes that to develop natural gas, we must first establish enough gas supply stations. Currently, there are a total of 4.96 million natural gas vehicles in 21 countries in the Asia Pacific region, and 6,800 gas stations have been built.

Xiong Weiming said that China is also making great efforts to build LNG facilities, and LNG vehicles will be the future direction of development.

It is also essential to have stable and long-term government support policies. At present, the domestic policy route is not yet clear. This is an important factor restricting the development of gas-electric hybrid commercialization. According to informed sources, the addition of a gas-electric hybrid system for buses requires an increase in the cost of 400,000 yuan, and the country has not yet introduced a corresponding subsidy policy.

In addition, natural gas vehicles are now mainly buses, but in the future, they will also develop into the field of passenger vehicles. Gas-electric hybrid vehicles have also become a hot spot for new energy vehicles after the hybrid electric vehicles. China's largest natural gas engine manufacturer, Shangchai Power, therefore ranks its natural gas business as an important direction for its future development. Xiong Weiming said that the company's natural gas engine production and sales are still less than 10% of the total, but will be developed to two to three percent after three years.

Professor Ouyang Minggao of Tsinghua University believes that the country has made the development of new energy vehicles a major strategy. At present, practical natural gas vehicles are the mainstay. At present, the number of natural gas vehicles in China has risen from about 1,000 units in the initial period of development 10 years ago to 400,000. With the advancement of coal seam gas, biogas, and biogas production technologies, natural gas-based gas will be integrated into a pipeline in the future. supply. According to the plan, by 2012, the number of domestic natural gas vehicles will increase to 1 million and use 1.6 million cubic meters of gas, which will replace 6.4 million tons of gasoline and diesel; by 2020, this scale will increase to 3 million, replacing 16 million. Tonnes of gasoline and diesel. Although electric vehicles are a global trend, natural gas can still be used as a fuel cell transition.
