With the continuous improvement of national emission requirements, environmental protection has become a hot spot in society. For truck companies, it is incumbent on responding to environmental protection requirements. In addition to the upgrading of Truck IV products, trucks that use natural gas as a fuel are also the first choice for users to purchase cars. In addition to traditional natural gas trucks, dual-fuel trucks that can use gasoline and CNG as fuel have also driven a new trend. 　　 Era 1600 Body 486CNG Dual Fuel Products Times Qiling VQ5 dual fuel vehicle Tang Jun Xiao Bao Ma Dual Fuel Vehicle Auxiliary Tool,Measuring Instrument Crucible Holder,Coal Samples Drum,Sample Preparation Components Drum Shaoxing Dongjing Machinery Instrument Equipment Co.,Ltd. , https://www.sxdj-machine.com
The crowded cars of the company are constantly launching
The research and development of dual-fuel products is no longer a one-size-fits-all solution. Why do we value dual-fuel products so much? “The introduction of dual-fuel products is mainly based on user demand and regulatory compliance. On the one hand, gasoline and natural gas are on the emission standard. Easier to achieve compliance, better environmental protection, and economic considerations, the use of gasoline or natural gas is lower than the cost of diesel, the user's transportation costs can also be saved.†Foton Automobile Engineering Products Division head said.
It is understood that many companies based on light trucks have introduced dual-fuel products based on gasoline and natural gas. JAC's early launch of the JAC micro-gasoline version in 2012 has a dual-fuel design. The era of light truck-based era is not far behind the launch of the era of Mitsubishi, era Kangrui and other series of dual-fuel vehicles, has been enthusiastically sought after by users. Tang Jun car focuses on the development of light truck products. In the series of products launched, it basically involves dual fuel vehicles, providing users with more choices. This year, the Foton Automotive Engineering Vehicles Division also launched the Era dual-fuel vehicle in the market after insight into market demand, adding new products to environmental protection and economic models. 
From the above it is easy to see that the introduction of dual-fuel vehicles are mostly light-car companies, so does the heavy-duty truck also have dual-fuel products? The answer is yes, the joint truck is equipped with a 460-horsepower joint-power DPCI dual-fuel engine model, with a ZF 16-speed gearbox, In August 2014, the road test was completed and the application announcement was filed. As long as the announcement was approved, the user could set the car. It is understood that this dual-fuel engine can have no natural gas, but it must have diesel fuel. At the same time, the engine has both a diesel ignition mode and a co-firing mode, which opens the way for heavy-duty dual-fuel vehicles.
Market makes thrust light truck product advantages gradually become prominent
The introduction of dual-fuel vehicles is not accidental. For users, the cost of replacement of the country’s four emission-elevated new vehicles, the cost of rising oil prices, and increasing transportation costs have caused them to agonize. How to balance transport and costs is both the needs of users and the direction of the company. 
It can be said that the introduction of dual-fuel vehicles is gradually getting closer to the ideal model of the user's mind. In terms of economy, the dual-fuel vehicles launched by Time Automotive put forward the concept of “one vehicle in three years of provincesâ€. The data shows that when using natural gas power, the loss is small, 50% less than using gasoline, and body streamline design. Less wind resistance is about 5%. Dual-ECU intelligent control system is standard, fuel saving is about 5%, and at the same time, the cost of gas is used to reduce the operating cost of the entire vehicle by 1/3, which shows the economy.
For the users' concerns about endurance and refueling, this contradiction is gradually being resolved through the efforts of companies and the general public. The dual-fuel vehicles introduced by Tang Jun Automobile adopt the 2+1 structure (2 65L gas tanks and 1 45L fuel tank), long vehicle mileage, economical benefits, and double insurance. In the era, the fuel tank volume of the dual-fuel vehicle is 50L, the volume of the gas tank is 80L, and the dual fuel is intelligently switched. The cruising range is more than 800 kilometers. The biggest advantage of dual-fuel vehicles is that they can switch fuels between oil and gas. In the case of inconvenient refueling, they can use gasoline instead, and they can flexibly choose the perfect overall life.
Dual-fuel vehicles currently use CNG fuels. CNG has been widely used and used much earlier than LNG. The number of CNG refueling stations is far greater than that of LNG stations and widely distributed. In provinces with abundant air supplies, almost all counties Both have more than one CNG filling station. For a short-haul, light-duty card, CNG filling station coverage and air supply protection are not a big problem.
Dual fuel technology is difficult to fully promote heavy trucks
Although the advantages of dual-fuel trucks are obvious, many users are happy to accept them, but they are not fully promoted in the truck market. They are only used in light truck products, especially in the heavy-duty truck market that requires efficient logistics and transportation.
As we all know, light truck products are mainly used for urban-rural and urban-to-city logistics transportation. The transportation distance is not too great. The carrying capacity is limited, but it is a few tons. However, the frequency of use is high, and uninterrupted use is on the one hand, on the quality of the products. The most important test is the consideration of fuel costs. The design of dual fuel products is more appropriate for light trucks.
In view of heavy trucks, heavy trucks generally have a long transportation distance and high freight weight. Although fuel economy is also highly valued, in addition, traffic characteristics and transportation weight also require consideration of dynamics. However, the current dual-fuel truck power technology cannot meet the optimal combustion conditions of both fuels at the same time, neither from the ignition point nor the torque compared with the diesel engine. Therefore, the dual-fuel engine has 10-20% of natural gas. The decline in power is also not negligible. Therefore, the dynamic nature of dual-fuel power technology makes the application of heavy-duty trucks a little more complicated, plus some long-distance transportation distance for the instability of the gas source, dual-fuel truck technology is not favored on the heavy truck is also reasonable in.
It can be said that the current dual-fuel trucks can not be fully promoted mainly from the constraints of technology, I believe that as more and more people turn their eyes to dual-fuel trucks, their technological breakthroughs will also be just around the corner. At the same time, it needs to be reminded that with the application of dual-fuel power technology on light trucks, more and more users have begun to purchase and use them. This requires companies to do relevant after-sales services and encourage everyone to purchase the dual fuel technology that comes with the factory's own fuel. product.
In any case, in the pursuit of environmental protection and economy today, dual-fuel vehicles provide users with more choices, especially the dual-fuel light trucks bring real benefits to the users of second- and third-tier intercity logistics transportation. Market development The potential can not be underestimated, let us continue to pay attention.
