Recently, it was learned that after the Xizi Cryogenic LNG engine was successfully marketed and received favorable comments, the largest 420-hp LNG engine CA6SN1-42E4N2, jointly designed and developed by FAW Group's technology center and Xichai's R&D department, was successfully developed into the 2011 version. Liberation of J6P heavy truck main driving force.
At the same time, Xichai re-calibrated and developed the LNG engine CA6SN1-39E4N2 on the basis of 420 horsepower. A breakthrough has also been made. The first batch of 20 Liberated J6P heavy trucks matching the Xichai LNG natural gas engine CA6SN1-39E4N2 will be exhibited in Gaomi, Shandong. . 
The LNG natural gas engine is an LNG fueled vehicle engine. Compared with diesel fuel, LNG can reduce energy consumption by 40%. Compared with diesel, gasoline, and gaseous natural gas (CNG), LNG has higher purity and energy density than CNG. 3 times, 400-500 kilometers can be driven once.
The successful development of the Xican liquefied natural gas (LNG) engine CA6SN1-42E4N2 has not only filled the gap in the application of the high-power LNG natural gas engine industry of more than 400 hp in China, but also marked a major breakthrough in the matching of the Xicca LNG natural gas engine in the heavy truck field. 
According to the liberation J6P vehicle market performance in the Heilongjiang Dalianhe coal mine, Wuhai, Inner Mongolia, and Guanghui districts in Xinjiang, the Xichai LNG engine has strong power and low-carbon environmental protection, and is known as natural gas resources such as Xinjiang, Inner Mongolia and Shanxi. The long-distance transport in the vast area is the most effective green supporting power.
The high level and high starting point are the basic principles for the development of LNG engines by Xichai. The CA6SN1-42E4N2 was successfully designed and developed on the basis of the Aowei CA6DN1 engine. It uses the most mature American EControl gas control system and LNG storage tanks. The lighter weight is longer than that of vehicles using CNG engines. Its natural gas engine EOL production management system and fault diagnosis instrument meet the market requirements for natural gas engine batch production and after-sales service.
In particular, regarding the gas consumption indicators that users are most concerned about, natural gas flow controllers adopt electronic pressure regulator (EPR) technology and international advanced air-fuel ratio closed-loop control strategy. The minimum external gas consumption is ≤ 190g/kW•h, 100 km. Save more than 30% on fuel costs. 
According to the person in charge of the Xichai Gas Project Group, the greatest advantages of the CA6SN1-39E4N2 engine are embodied in environmental protection, gas consumption, power, handling and reliability. The LNG engine accurately controlled the gas flow through the D-EPR, achieving low emissions and high economy. It reduced carbon monoxide emissions by 90%, carbon dioxide by 20%, and hydrocarbons by 60%.
At the same time, it has a large engine displacement and a high degree of reinforcement. Its BMEP is also at the leading international and domestic level, with a maximum torque of 1700N.m. And through the development of electronic control functions, CAN meters can be directly connected, with the vehicle cruise function, speed limit function, PTO function, real-time gas consumption display and other special features.
With the deepening of energy-saving and emission-reduction policies, the market trend of the Xichai LNG engine will continue to climb. The resulting dynamics and economy will also create great value for customers. The market demand will become increasingly popular.
