· Push CNG first and push LNG Xiamen to promote natural gas buses cautiously

According to the Xiamen Public Transport Group, the total number of buses in the city is about 4,000, and the proportion of clean energy buses exceeds 15% (about 650). Among them, there are more than 410 CNG buses and more than 240 LNG buses.
What is the promotion pace of the two types of natural gas buses in Xiamen? What about its operation?
First push the CNG bus and push the LNG model in the downtown area of ​​Xiamen Zhongshan Road and Siming Road. The reporter observes that the natural gas bus coming and going is almost the same as the new energy bus. It is also green and white. The words on the logo are different. Moreover, most of the natural gas vehicles that come and go are LNG buses, and the number of CNG models seen is significantly smaller.
A driver of the 20-way Dajinlong LNG bus explained: "That is because Xiamen LNG bus is late, and cars like LNG buses are relatively new, and will basically be arranged on the route passing through the downtown area."
In the 3rd bus terminal of the “First Terminal”, the reporter learned from a 3-way driver that since August 2010, Xiamen has successively launched 300 CNG buses, all of which are Dajinlong brands. “The first batch of cars was first put into 50 vehicles, and the length of the car was about 10.5 meters. Its shape is almost the same as that of ordinary buses. The biggest difference is that only one box is placed at the top of the front end of the vehicle, and the 'CNG' logo is attached. It is used on three lines of 3, 46 and 99."
A person from the Xiamen Public Transport Group said, “We tried to use natural gas buses for the first time and were very cautious about vehicle safety. Dajinlong also designed three safety valves and air leakage alarms for the vehicles. The body also uses high-strength steel to ensure The safety of the vehicle."
Since 2010, Xiamen has invested more than 400 CNG buses, and it is only this year that it began to try to promote LNG buses. According to the relevant person, "In the first half of this year, Xiamen added 246 LNG buses, accounting for 71.3% of new buses, but no new CNG models."
Different from the promotion of CNG models, Xiamen purchased the two brands of Dajinlong and Jinlv when implementing LNG buses, and no longer only used one brand. “We have multiple buses on the station with LNG models. These brands have both Dajinlong and Xiaojinlong (Golden Travel).” A staff member of the dispatching room of the 19B Bus Convention and Exhibition Center has said this.
LNG car is better than CNG car: it is convenient to refuel and has a long driving range. Why did CNG bus be promoted in Xiamen early, and LNG bus was developed in the later stage? Perhaps this is the answer to the operation of the two types of models.
"These cars are not much different from diesel cars. It is a bit of trouble to refuel. It is not only necessary to add gas once a day, but also takes a long time to refuel." When the reporter asked about the operation of CNG buses for many years, one The three-way bus driver who opened the CNG car said this.
The driver said that they spend a lot of time on the vehicle every day. "This type of car adds a gas, and it can run for up to 250 kilometers, which is the daily operation time of the bus. Therefore, it is necessary to add gas once a day. Moreover, this type of car has a long refueling time, which takes more than 10 minutes or even 20 each time. More than a minute, and the diesel car will add about 3 minutes to the oil.” He also complained that the CNG car is louder and has a weaker start.
What about the LNG bus in operation? At the bus terminal No. 135 of the “Xiamen University Apartment”, a driver of a 135-way LNG bus (12-meter car) told reporters that “the LNG car we have opened has an advantage over the CNG bus. First of all, this type of car has a longer driving range. After adding a gas, it can run for about 500 kilometers. It can be added once every two or three days. Secondly, this type of car can be used in the same way as a diesel car. It can be 4 or 5 minutes. Top up, don't wait."
Perhaps it is because of the convenience of LNG bus operation. Xiamen also invested 18 LNG double-decker buses on the 10th road in July this year. “The double-deck LNG bus we opened has a larger weight than the ordinary LNG model, but the power is still good, which is a bit slower at the start.” A driver of the LNG double-decker bus of Jinjin Brigade commented.
According to relevant sources of the Xiamen Public Transport Group, “Before the end of the year, Xiamen is expected to continue to invest 100 LNG buses, but there is no new plan for CNG buses.” So, will Xiamen abandon CNG buses in the future and turn to full promotion? LNG bus? Please pay attention to the follow-up report of Fangde.
