Many people can hardly imagine that 50 years ago, a heavy truck with a load of 10 tons had a fuel consumption of 50 liters per 100 kilometers. Today, with a heavy truck with a load of 25 tons, the fuel consumption of 100 kilometers can even be controlled within 30L, how is this achieved? Today, let's take a look at the history of fuel consumption changes in China's heavy trucks.
1950s-80s: The era of fuel-hungry military trucks
In the early days of the founding of the People's Republic of China, the smoke of World War II had just ended, and the trucks of various countries were still in the stage of military-oriented use, and the trucks at this time pursued stability and safety, and the fuel consumption was quite high. In 1956, China's first truck CA10, in Changchun FAW Assembly Plant off the production line, this truck in the former Soviet Union military truck Gies 150 as a prototype, the load of only 4.4 tons, the maximum speed of 70 km / h, but the 100 km fuel consumption has reached 29L.
By today's standards, ca10 is used as a transport with no "value for money" at all. However, as the first batch of mass production trucks in China, CA10 was converted into a bus ambulance, refueling truck, water truck, dump truck, crane truck, and engineering vehicle, and undertook a large number of infrastructure responsibilities that year. In the early 1970s, China produced a heavy off-road truck of more than 10 tons - Hongyan CQ261, with a maximum speed of 61Km/h, fuel consumption of up to 50L per 100 kilometers, and six-wheel drive, which was mainly used for troops to pull artillery.
The 80s-00s: The Steyr era of leapfrog progress
After the reform and opening up, the freight volume surged, the market began to pay attention to transportation efficiency, and it was difficult for military heavy trucks with high fuel consumption and low load to meet the demand for freight. So, in 1984, we introduced the Austrian Steyr 91 series of 14-to-40-ton heavy trucks. In 1985, the first Steyr 91 rolled off the production line at the Sichuan Automobile Factory, and mass production began in the 1990s, becoming the main transport vehicle at that time.
With the advantages of low fuel consumption and high load, Steyr trucks quickly swept China's transportation market. Take the classic Steyr 1491 model as an example, the maximum load can reach 20 tons, the maximum speed is 72km/ h, and the fuel consumption per 100 kilometers is 37L. Compared with the 10-ton load and 50L fuel consumption of military trucks in the previous stage, the economy has been greatly improved. It is said that 7 of the 10 trucks running on the road that year were Steyr, which is the childhood memory of many card friends.
The 1900s to the present: the era of commercial vehicles with a hundred flowers
Entering the millennium, the transportation market is more prosperous. At the same time, Nissan heavy trucks, European heavy trucks, the United States and other countries' advanced car manufacturing technology has been introduced into China, and the heavy truck technology lines are diversified, showing a situation of a hundred flowers. At this stage, the competition in the transportation market is gradually fierce, and the market has put forward higher requirements for truck capacity and fuel consumption, and pays more attention to the economy, safety and power of trucks.
Driven by the market, many car companies are based on global advanced technology and take fuel saving as one of the focuses of research and development. Through engine optimization, vehicle lightweight design and a series of scientific configurations of the power system, China's domestic heavy trucks currently have unique advantages in carrying capacity and fuel consumption. According to Master Kayou Yang, the Hongyan Jieshi H6 tractor he drove, equipped with SAIC-powered SC13 engine, departed from Chengdu to Suzhou, with a total weight of 40 tons and a fuel consumption of only 27.5L per 100 kilometers, which can be described as a new height of fuel saving.
Looking back at the history of truck fuel consumption in China, it is not difficult to see that market demand has prompted truck fuel consumption to be reduced, and technological progress is the premise of realizing demand. At present, China's transportation market competition is still fierce, for a long time, high economic low fuel consumption heavy trucks will still be the protagonist of the market.
