Big torque is cool, take stock of the latest high-torque tractor truck

High-horsepower and high-torque models have the characteristics of fast acceleration, strong power, low failure rate and good economic benefits. Compared with the previous few years, there are only a handful of models with a torque exceeding 2000Nm, but now it is in a situation where a hundred schools of thought contend, so today I will take stock of the current domestic cars with engine torque exceeding 2000Nm.

● Advantages of high torque engine Features

   Longer life and higher reliability

Under the condition of the same total weight of 55 tons and a speed of 90 kilometers, the high-torque engine can match the rear axle with a smaller speed ratio, so that the engine can reach the predetermined speed at a lower speed, while the low-torque engine can ensure the vehicle's speed. The traction force has to be equipped with a rear axle with a large speed ratio. If you want to achieve a higher speed, you have to increase the speed of the engine, and the higher the speed, the greater the wear and tear. Therefore, the life of a low-torque engine will be longer than that of a high-torque engine. the difference.

Use a simple analogy to explain the reliability. The same 100-pound thing can be easily resisted by an adult, and a minor can resist walking even if he works hard, but if both of them are allowed to carry 100 pounds It is quite easy for adults to walk one kilometer of something, but minors inevitably have to stop and go on the road.

This is the relationship of load. The same 100 catties weight is very easy for adults, but it is very difficult for minors. If a minor is to bear such a large load for a long time, there will definitely be problems. The same is true for the engine. If a low-torque engine is operated at a high load for a long time, its failure rate will be quite high.

   Better starting performance and faster acceleration

Why is it said that an engine with more torque has better acceleration performance? For example, two cars of the same weight are on the same starting line. Now one car is pushed by 2 people, and the other car is pushed by 10 people. At the same time, it starts to push forward 100 meters, ten An individual can go 100 meters in 10 seconds, while two people need 20 seconds or more to go 100 meters. For the same reason, the starting performance of a high-torque engine is faster than that of a low-torque engine.

The large torque engine can not only improve the acceleration performance of the vehicle in the plains, but also deal with the mountainous and hilly road conditions with ease. The small torque engine often needs to downshift several times when encountering mountain roads to ensure the driving force of the vehicle. In this way, the average vehicle speed is will drop significantly.

The high-torque engine has a large power reserve, so it is quite easy to deal with mountain and hilly road conditions, and there is no need to ensure the driving force of the vehicle through frequent downshifts. This will ensure that the average speed will not drop too much, with better timeliness.

more economical

We all know that the speed is determined by the amount of fuel injection. The higher the amount of fuel injection, the higher the speed of the engine, and the higher the speed, the greater the fuel consumption. Since the high-torque engine can match the rear axle with a smaller speed ratio, the engine can reach the predetermined speed at a lower speed, while the low-torque engine has to be equipped with a rear axle with a large speed ratio in order to ensure the traction of the whole vehicle. To achieve a higher speed, you have to increase the engine speed.

Therefore, within a certain range, the high-torque engine not only has higher reliability and service life, but also has better fuel economy, which can create greater economic benefits for users.

Auman GTL super version 430 horsepower 6X4 tractor truck

Compared with the previous generation of ETX, the style of the front face of the GTL super version retains the genes of the previous generation, but the overall height of the bumper and the lengthening of the distance between the headlights and the fog lights make the whole style closer to the European style. The GTL super version will be the first domestic model equipped with a Cummins ISG engine.
