Domestic big passenger gas to gas surface high cost dilemma

In recent years, all mainstream passenger car manufacturers have introduced their own hybrid products. In the use of natural gas fuels, the fuel mixture is mainly gas-electric hybrid. The low price of natural gas is well known. Then, will the release of “oil to gas” set off a trend of “oil to gas” in the commercial vehicle sector?
"Hydrocarbon" mixing does not mean that hybrid vehicles do not have the form of oil and gas mixture, because the two are technically difficult to mix, and fuel utilization is not as good as oil and gas, electricity and gas mixture.
"Yuchai's hybrid engine products are mainly based on oil and electricity, and the energy efficiency of hybrid products is even higher. There is also no way to mix oil and gas, but only gasoline and natural gas are mixed, and it is on small cars such as taxis. More applications, diesel vehicles do not have the form of oil and gas mixture." Yu Xue, director of Guangxi Yuchai's new quality management office, told reporters.
At the same time, he also said: "Difficulty in mixing diesel and natural gas, gas engines and gasoline engines are used to ignite fuel through spark plugs, but diesel engines are compression-ignition engines with no spark plugs. If you want to mix diesel and natural gas, you need to The use of spark plugs, but also the use of fuel injectors, the difference between the two ignition methods are too great to achieve the technical difficulty of mixing."
“Oil to gas” price is not low According to reports, “There is indeed a demand for converting diesel buses into gas vehicles on the market. To find manufacturers to change and find repair shops to change, manufacturers must be more professional. The cost of buses is not low, the engines need to be replaced with gas engines, and the fuel tanks must be replaced with gas cylinders. Not to mention the engine, the price of a gas cylinder is more than 10,000 yuan, so the cost of buses to convert gas to gas is high. There are not many users who have this requirement, said Li Gong, planning engineer of Suzhou Jinlong Product Management Office.
At present, “oil to gas” is used more in small vehicles such as vans. The first is that its economic benefits are more prominent in vehicles with more mileage, and the second is lower conversion costs of small vehicles.
"Yinchuan has more filling stations and it is convenient to add fuel. Many taxis have changed from burning oil to gas. There are also many vans that pull or pull people at ordinary times to carry out 'oil to gas'. The location does not affect the normal use of the interior space, and it can run for nearly 200 kilometers in one gas run. In Yinchuan, there are more than 10 filling stations that I know, avoiding the rush hour when taxis change classes. It is convenient not to line up, even if it is not possible to refuel in time, you can also burn oil first.The cost of natural gas is only half that of oil, and the cost of going to a regular conversion plant is a few thousand dollars.You can save the cost of modification by running for one year. There are even a lot of domestic cars that are beginning to 'change to oil'," said one user of Yinchuan's “oil to gas”.
Mixing with "Electricity" is the Mainstream Since "oil-to-gas" involves the issue of refitting costs, can we learn from the popular hybrid model to use natural gas energy?
Broadly speaking, a hybrid vehicle is a vehicle that has at least two power sources and uses one or more power sources to provide some or all of its power. However, in actual life, most hybrid vehicles use conventional internal combustion engines and electric motors as power sources, and the automobile is operated by using a combination of two systems of heat energy and electric power. A hybrid vehicle using a gasoline engine or a diesel engine is a hybrid vehicle; a hybrid vehicle using a natural gas engine is a gas-electric hybrid vehicle.
Hybrid power is widely used in the passenger car industry. In recent years, all mainstream passenger car manufacturers have introduced their own hybrid products. In the use of natural gas fuels, the fuel mixture is mainly gas-electric hybrid.
“The Zhongtong hybrid bus is mainly gas-electric hybrid, which accounts for more than 60% of the total. There are many hybrid buses in the passenger car market that are hybrid vehicles, and there are also hybrid forms of electricity and gas. As the construction of gas stations is becoming more and more common and lower natural gas prices can bring better economic benefits to customers, the future will see more and more hybrid gas-electric hybrid buses. It is mixed with 'electricity' and there is no such form of oil and gas mixture." Li Tongsheng, Minister of the Ministry of Culture of Zhongtong Bus Brand, told reporters. “Our hybrid bus has two forms of gas-electric hybrid and hybrid-electric hybrid. There is no other hybrid method. There are also two forms of hybrid vehicle on the current bus market,” Li Gong told reporters.
