What's The Matter Of Driving A Stall? These Two Situations Of Stalling Need Attention. Howo Truck Parts

What needs to be paid attention to when driving a stall

At present, the majority of domestic trucks in China are mainly manual gearboxes. Shifting is a very frequent operation during driving. Grasp the appropriate shift timing and select the appropriate gear, which is critical to vehicle power and fuel consumption. Important, but there are still some people who will inevitably experience stalling while driving.

So what is a stall?

There are actually two main types of towing gears. The first one is very familiar to everyone, which is high-end low-speed towing, that is, a higher gear is selected when the vehicle speed is not enough to reach the gear, or the gear is not downshifted in time.

The engine speed does not reach the speed necessary for this gear, which affects the normal operation of the vehicle or engine, increases engine wear, and reduces the service life of the engine. This phenomenon is common when the vehicle starts or the vehicle is traveling.

The second is low-speed and high-speed towing. This situation is exactly the opposite of the above, and it is easy to make the engine run at an excessively high speed.

Each engine has its own specific speed-power characteristics. Once it exceeds the optimal operating range, it will consume fuel sharply. At the same time, over-speed operation will put too much pressure on engine components.

No matter what kind of drag is not a good phenomenon, it will have a bad impact on the machine and will cost fuel. Regardless of the kind of stalling, if running for a long time in this situation, on the one hand, high fuel consumption affects the economy of the vehicle, and at the same time, it will cause damage to the engine and the transmission, and affect the service life of the vehicle.

In recent years, truck engines have entered the era of electronic control. At the same time, the displacement and horsepower have become larger and larger, and the economy has also been improved. Many engines have promoted the characteristics of low speed and high torque. The lower the speed, the more fuel efficient. But a lot of people are accustomed to the mechanical pump, which is what we commonly call the big pump model.

Many models are equipped with instantaneous fuel consumption meters. Some friends will be greatly affected by this. They pay too much attention to the instantaneous fuel consumption and the speed of the shift is too low, resulting in a lower speed after the shift. This will also cause the vehicle to drag during driving. Case.

There is also a poor understanding of the economic speed range, and it is often chosen to shift gears at lower speeds. In some cases, this is not appropriate. In fact, the speed is slightly higher after the gear shift, and then the fuel is driven. There is also some control over fuel consumption. Help.

For some friends, due to labor saving in long-distance driving, the gear shift is not timely and diligent, which will cause dragging gears, which will cause corresponding increase in fuel consumption.

In short, dragging is a very bad driving state. Long-term dragging is also good for fuel economy, or the engine, transmission, and vehicle powertrain system will have a bad impact. Long-term accumulation will lead to premature vehicle damage. Therefore, you should shift gears in time according to road conditions and speed to prevent dragging.
