What is the cost of towing when a car is running?

　　Nowadays, it's normal for social families to have cars. But many people buy cars but don't drive! Accelerator manufacturers to explain to you some of the basic knowledge of the car bar! Why does the "towing gear" consume fuel when the car is driving, so that you can know more about the car! ___________ Let's learn together.

　　1. What is "dragging file"

　　When the driving resistance is greater than the traction force, if the engine is not shifted in time, the engine will be forced to slow down to unstable working state. This phenomenon is called "towing gear".

　　2. Accelerator manufacturer will show you the performance of towing gear

　　Procrastination is what we are accustomed to saying about not shifting in time. When the power of the engine is insufficient, the driver fails to change gears according to the terrain and the sound of the engine, so that the kinetic energy of the engine can not be fully utilized. Dragging not only consumes oil, but also aggravates abnormal wear and tear of engine moving parts. For example, when a car is going up the hill, the four-gear accelerator is fully open and the initial speed is 50 km/h. When the speed drops to 30 km/h, the sound of the engine begins to change and knock. If the speed drops to 25 km/h, the sound of the engine will become dull, the speed of the engine will be very unstable, and even the fire will be extinguished.

　　3. Accelerator manufacturer tells you the reason of fuel consumption in towing

　　Vehicle fuel-saving speed is the economic speed, while the speed with high fuel consumption is the upper or lower limit of the economic speed, such as Jiefang Truck. When the engine is 1600 r/min, the fuel consumption is the lowest, which is the best economic speed (equivalent to 4 gears, the speed is 40 km/h). When the speed drops to 1200r/mi n, the maximum output torque of the engine increases, but the fuel consumption increases. When the speed of the engine decreases again, the working condition will be unstable, which will be aggravated with the gradual decrease of the speed. The power of the engine decreases sharply and the fuel consumption increases.

　　The "towing gear" makes the engine work in a disadvantageous condition and consumes oil. Therefore, when the driver is driving, when he feels the sound of the engine becomes dull, he should reduce gears in time to save fuel.
