On February 1st, 2014, the national launching ceremony for the J6 full-line natural gas products was held in Hebei, a major logistics province. The products launched this time covered traction, cargo loading, dumping, and special vehicle varieties, fully satisfying market segments. Different user needs. What about the performance and advantages of liberating J6 natural gas products that our truck users care about? Xiao Bian today through the introduction of the X6 diesel engine built on the release of the Xichai engine , so that the majority of users have a clearer understanding.
Equipped with Xichai Aowei series natural gas engine liberated J6 natural gas models
In fact, compared to oil-fired trucks, natural gas users have the most doubts and are most concerned about the following five points, but the Liberation J6 natural gas vehicle can effectively overcome the vehicle problems brought by natural gas vehicles with its six dedicated technologies.
The first point is that natural gas vehicles have less power than diesel vehicles with the same displacement or power, reflecting that the vehicle is boring during the driving process and it always smells exhausted.
Secondly, natural gas trucks have low attendance. Due to changes in the fuel supply system, many technically immature products will have a higher failure rate. The serious phenomenon is that we have to repair it once, and this is what our users can't afford. of.
The third point is that failures do not say much, maintenance costs are still high, and not every area's after-sales service can be repaired in the face of natural gas trucks. This is also where our users are worried.
Fourth, LNG filling stations are unevenly distributed and have an advantage over diesel prices. Fortunately, the former said that the general choice of natural gas truck users have a clear understanding of their own operating environment, can guarantee their own vehicles plus gas, the most contradictory is the latter point, especially after the oil price fell in the last six months The cost advantage of burning gas is no longer obvious, and many users have begun to hesitate to choose natural gas trucks.
The fifth point is the weight of the vehicle. This is also a point that users value very much. Generally, two natural gas vehicles equipped with 450L gas tanks weigh about one ton compared to diesel vehicles of the same displacement. This is very important for users who are engaged in 55T standard transportation. There is lethality.
The sixth point is the safety of gas cylinders. Compared with the current cylinder technology, the problem has been greatly improved. In particular, like the Jieri J6 used Furui equipment or San Tin tanks, are the leading domestic LNG vehicle cylinder manufacturers, quality assurance.
Then how to overcome the above six main issues? We can find the answer from Dr. Dou Huili of the FAW Liberation Technology Center.

The quality of trucks depends on the engine. This is no exception for natural gas trucks. FAW Jiefang J6 natural gas products carry Xichai Aowei series natural gas engines. The product range includes 6SL2 (horsepower coverage 220-290) and 6SM2 (horsepower coverage 310-370). And 6SN1 (horsepower coverage 350-420), including 9L, 11L and 13L and other large-displacement output, all-round support Jiefang J6 medium and heavy vehicle power needs. The key is that the Xichai natural gas engine has a unique six special technologies, technology: Xican natural gas engine using a special cast spark plug sleeve cylinder head, compared to the press-fit spark plug cylinder liner, effectively reducing the leakage, leakage of oil occurs, use Longer life. Technology II: Xichai natural gas engine adopts special valves and valve seats for high temperature resistant powder metallurgy materials. The wear amount of 100,000 kilometers is only 0.18mm. Compared to products with the same mileage mileage of 1mm, the service life can reach 800,000 km. Obvious advantages. Technology III: The Xichai natural gas engine adopts a special bowl-type piston ring set, which has good sealing performance, effectively reduces oil consumption, and produces carbon deposits, which improves the reliability of the ignition system. Technology IV: Xichai natural gas engine adopts special moving parts design, such as high-performance piston jointly developed with Mahler, high-performance piston rings jointly developed with Diborkoz, and high-performance bush developed jointly with Miba, etc. In conjunction with the world's leading parts suppliers, the reliability of the Xichai natural gas engine has been greatly improved. Technology 5: Xichai natural gas engine uses a special ignition system, such as the use of the United States "champion" imported sheet metal spark plugs and high-performance ignition coils. The service life of the spark plugs of the Xichai natural gas engine is as long as 100,000 kilometers, which can reduce the cost of 1,200 yuan per year compared to competing products. At the same time, the ignition system has a six-month warranty period, which is unique in China. It can be seen that the advanced technology and reliability of product technology. Technology 6: The Xichai natural gas engine adopts a special valve sensor, which has high precision and long service life. The service life of the valve system is 100% higher than competing products.
Xichai Aowei 6SM2 11L natural gas engine
Through the analysis of the six special technologies for Xichai Aowei series natural gas engines, it is not difficult for us to see its product advantages. In addition, Xichai gas engine also has the world's first single-cylinder four-valve, overhead camshaft technology of gas-saving technology, gas distribution accuracy, fuel mixing, combustion efficiency is higher. At the same time, through the cooperation with ENOVATION CONTROLS, E-controls lean combustion technology is adopted. With the energy saving effect of the whole vehicle, the minimum gas consumption rate is 183g/km?h, which can achieve 2 kilograms of solar energy for 100 km and save the user one year. 18,000 yuan.

The reliable and fuel-efficient Xvek series natural gas engine brings the biggest advantages to Liberated J6 natural gas vehicles: "a big two provinces," a "big" and high horsepower, Aowei 6SM2 (horsepower covers 310-370) and 6SN1. (horsepower covers 350-420) Comparing with the displacement of the competing products exceeds 1L, the domestic displacement is the largest, which brings greater torque and horsepower. It is easier to liberate J6 natural gas vehicles from climbing overtaking. "Two provinces" and save money and worry. Relying on Xicai's six dedicated technologies and unique solar technology, it ensures that the J6 natural gas vehicle is safe, reliable, and economical.
