In recent years, the trend of heavy truck adaptation to high-horsepower engines has prevailed, and the development momentum has become more and more rapid, once 430, 460 horsepower, and then to the previous two years of hot 560, 600 horsepower matching, are all showing the good charm of high-horsepower engines.
In 2023, it seems that 600 HP is no longer a novelty, and 16 -, 17 – liter displacement 700 HP and 800 HP engines begin to hit the market. In comparison, the “big horsepower” of the past appears to be a little trivial. In just a few years, the global engine displacement and power improvement speed are undoubtedly huge, however, we can not help but ask, is it necessary for buyers to have high-horsepower models? What are its advantages?
Freight development will inevitably increase this efficiency is the goal
At present, in the domestic freight market environment, low operating prices, car maintenance costs, labor costs and market competition and other reasons, for operating owners or logistics enterprises, reducing operating costs is a most concerned issue.
So, how to find an effective way to reduce costs and increase efficiency?
At this time, high-horsepower models into our vision, the biggest advantage of high-horsepower models is to help the owners of the operation to reduce costs and increase efficiency. Therefore, 500 horsepower and 560 horsepower models are more and more used in transportation scenarios.
Efficient and fuel-efficient long life is much more than just running fast
The most intuitive performance advantage of the high-horsepower engine is that it has more power and more sufficient power reserve, which can bring faster operation to the vehicle, which can shorten the one-way transportation time, so as to improve the transportation efficiency of the vehicle.
If you look at the structure alone, the large-displacement and high-horsepower engine is indeed more fuel-intensive than the small-displacement engine, but for the overall car and the transportation scene, whether the vehicle is fuel-intensive is not only dependent on the displacement of the vehicle engine. Take the simplest example, which is more laborious, small horse big car and big horse small car, needless to say, I believe you have your own answer.
Whether it is climbing or high speed operation, under the same road conditions, small horsepower models want to maintain a high speed at all times, it is necessary to ensure a high speed, large throttle state, vehicle fuel consumption will inevitably increase, for high-horsepower models, their own power is sufficient, even under high speed operation, The engine can also maintain a low speed (economic speed range) operation for a long time, which will have better performance in terms of fuel consumption and driving comfort.
At the same time, the characteristics of low speed and high torque have always been one of the core advantages of high-horsepower engines, which can allow the engine to continue to maintain the economic speed range under complex road conditions, and can take into account low fuel consumption and strong power output. In this state, the engine is also in a long-term low-load, low-wear operation state, which can effectively extend the service life of the engine, improve reliability, and reduce the time and cost of maintenance.
The difference in time is basically not much in the plain section, but more in the mountain high-speed slope section. The high-horsepower and low-speed ratio models can complete the rapid climb in the more appropriate economic speed range, and the high-power engine cylinder braking of the high-horsepower models on the downhill section can also further improve the average downhill speed of the vehicles under the condition of ensuring safety. In the pursuit of extreme timeliness and the right route, the high-horsepower model may bring more significant advantages.
The vehicle matches the high price preferred for trunk logistics
Although the high-horsepower model has many advantages, it also has some shortcomings at present, among which the truck friends are most concerned about the price.
High-horsepower models are the flagship high-end flagship store models of various brands, with high configuration and comfortable driving, and the price will naturally come up. High-end heavy truck tractor at the price of 8-100,000 US dollars, for truck friends, it is true that some of the heart is willing but insufficient.
In addition, from the consistency of the vehicle matching, the hardware point of view are selected large displacement, high-horsepower engine + AMT gearbox coordinated with the engine calibration + small speed ratio rear axle power chain matching, while the engine selection is mainly 14-liter, 15-liter 600-680 horsepower segment.
This is in line with the development law of the current freight market, and in the current market, mature and reliable power chain products can be found, as well as more intelligent vehicle power chain adaptation and calibration.
So why not just introduce new high-powered models with 16 – and 17-liter displacement? First, because the current market does not need the emergence of such a high-horsepower model, it is only used for the optional adaptation of large cars. The second is that the current market can meet the displacement of more than 16 liters of engines, there are not many transmission products to meet the needs of the current majority of the mainstream transmission can not withstand too large input torque.
The third point is that the current high-horsepower models are more suitable for long-distance trunk standard load logistics transport, such as cold chain, green pass, express and other subdivision transport scenarios, long distance, high-speed, fast speed, are the common characteristics of the transport scene, but also can maximize the high-horsepower models of efficient, fuel-saving operation scenarios.
In the long run, the emergence of high-horsepower models has a great boosting effect on the rapid development and cost reduction and efficiency of the freight industry. At the same time, for users, while improving operational efficiency, their own car maintenance costs can also be further reduced.
Of course, faster is not always better, and more horsepower is not always better. Here it is also suggested that the card friends, although the high-horsepower models are good, but not easily blind choice, must be based on their own operating scenario status quo, to choose a reasonable transport model, blindly chasing the wind is not a good choice.
