People who live by the mountain and live in the mountains, in Luliangjiaokou County, Shanxi Province, are well versed in this truth. The same is true of Wang Jirong, who grew up here since he was a child. Relying on the rich minerals in Jiaokou County, Wang Jirong started the transportation business. The daily work is to transport the "treasure" in the mountains to the places where it is needed more.
Wang Jirong has his own convoy with a total of 8 heavy trucks, 4 gas cars and 4 fuel cars. Regarding how this year's earnings are, Wang Jirong said, "Compared to fuel vehicles, heavy trucks equipped with SAIC Power 12ET natural gas engines are simply a money-making weapon."

Powerful, not afraid of slope multi-road insurance
Running and transporting in mountainous areas has advantages and disadvantages for Wang Jirong. Jiaokou County is rich in mineral resources, including 14 types of coal, sulfur, iron, and aluminum, with a mineral area of ​​850 square kilometers, accounting for 67.1% of the total area, which makes Wang Jirong need not worry about the supply. But on the other hand, mountain roads are not easy to run, and there are many slopes and curves, which put forward higher requirements for vehicle dynamics and handling.
Wang Jirong introduced, "Our daily transportation route is not long, less than 20 kilometers one way, but there are many S-shaped curves, and these curves often have a certain slope, and some slopes are not small, reaching 45 °. So we have high requirements for the power of the vehicle. Strong climbing ability, high efficiency and low economic cost have become the criteria for my car selection. When replacing the vehicle in 2018, I selected a 390-horsepower SAIC 12ET natural gas engine. "
SAIC Power 12ET
The 390-horsepower SAIC 12ET natural gas engine lived up to expectations and perfectly met Wang Jirong's discerning requirements for vehicle engines. It uses turbocharged intercooling technology to maximize the maximum power of the engine, with a maximum torque of 1750N · m, and a wide range of engine revolutions that can reach the maximum torque, which can cover 1100 ~ 1300 revolutions per minute and has a fast start , Short acceleration time, strong climbing and overtaking capabilities.
"From the fuel-fueled vehicle to the gas-powered vehicle, no fleet driver reported to me that the vehicle ’s power was insufficient. Even from the time it took the drivers to transport, the efficiency was also improved. This was an accident after I used the SAIC Power 12ET natural gas engine. like."
Efficient solar terms can withstand low freight rates
However, when the dealer first recommended the gas car to Wang Jirong, he was very hesitant, worried that the gas car lacked power and could not adapt well to mountain roads. "The traffic conditions are special, and I must carefully consider changing the car. But the introduction of the dealer made me very enthusiastic. He guaranteed that the power would keep up and gave me an economic account. Gas prices are cheaper than oil prices and can significantly reduce costs. "
The introduction of dealers is hitting Wang Jirong's pain point when buying a car. In Jiaokou County, more and more people buy cars and run transport. The market is under great pressure from competition. Freight rates continue to be sluggish. If you want to maintain profits, you can only control from cost.
"There are both fuel- and gas-powered vehicles in the fleet. The comparison of costs and expenses is very obvious. The gas price is generally maintained at more than 3 yuan, and when it is expensive, it is more than 4 yuan. It is much cheaper than the oil price, and the gas vehicle will undoubtedly earn me more. Wang Jirong introduced, "In addition, SAIC Power's 12ET natural gas engine is also very powerful. The transportation routes are all mountain roads. With a total weight of 49 tons, the cost per kilometer is about 1.7 yuan, which is very good."
How does SAIC Power's 12ET natural gas engine achieve such economization? It is understood that SAIC Power's 12ET natural gas engine uses WOODWARD's mature and reliable OH2.0 electronically controlled gas system. Lean combustion technology is used to accurately control the air-fuel ratio. Coupled with the technical support of overhead camshafts, variable oil pumps, and low-elasticity piston ring sets, the gas consumption rate is only 182 ~ 185g / kWh.
Reliable quality with normal maintenance
In addition to daily cost savings, the reason why heavy trucks equipped with SAIC-powered 12ET natural gas engines can be called a money-making weapon by Wang Jirong is also the vehicle attendance.
"The heavy truck equipped with the SAIC Power 12ET natural engine has been used for more than a year. It has always been a high-load work, particularly durable, and has never been overhauled." Wang Jirong said proudly.
Wang Jirong checks engine status
It is understood that the structure design of SAIC Power 12ET natural gas engine is based on the burst pressure of 190bar (mostly the same type of engine is designed according to 165bar), so the overall structure has better durability and reliability. The fuselage adopts an integral cylinder head, which has better structural rigidity; the overhead roller rocker arm has a shorter transmission chain and higher durability; the cone angle of the intake and exhaust valves is reduced to improve the wear resistance of the valve and the seat ring; The connecting rod and the overall engine reliability are greatly improved. Not only that, SAIC Power 12ET natural gas engine also passed the bench reliability and endurance test of more than 20,000h during the research and development phase, and completed more than 1.5 million kilometers of multi-type and multi-mode special-equipment assessment and verification to ensure product reliability.
Wang Jirong revealed, "I have never had any trouble in using the SAIC Power 12ET natural gas engine. Usually the driver ’s sports car is working normally and is very efficient. When the engine needs maintenance, there will be a dealer reminder in advance, I Just confirm when the vehicle has no freight assignments and arrange for the driver to send it over. "
At the end of the exchange, Wang Jirong said, "I still have 4 fuel vehicles in my fleet, but the monthly profit is too small. If I have the opportunity to shoot, I will replace them all with SAIC 12ET natural gas engines. Heavy truck. "(This article comes from Shangchai)
