What is engine drag braking?
For the car, is a taxiway, because not to oil, then the engine is run by the inertia of the vehicle in the drag on the consumption momentum. For large vehicles, and an exhaust brake, on the taxiway at the same time, you can also use the exhaust brake, is to use the solenoid valve to the exhaust pipe when closed, to a certain pressure to open, because the engine exhaust is blocked, the greater the holding force is more obvious, this is now in the trucks and other large vehicles generally
Engine drag braking, that is, the use of the braking system to slow down the speed at the same time, gear stalls down to reduce the load on the braking system, in order to reduce the possibility of braking failure.. It can make the vehicle more safe and prolong the life of the brake system." This driving learning material on the record has been regarded as we strictly follow, not golden laws and precious rules, contrary to. This has led to the idea that a drag is a brake; a pull will certainly reduce the use of a car. Is that so? Whether the brake can be effectively used to brake and to improve the safety factor depends on whether the driver knows how to pull the gears. Either automatic or manual gear vehicle deceleration during driving, the driver only needs to press the brake pedal, the car will have deceleration under your control.
If at this time the direct use of drag block mode to realize deceleration, then there will be a driver hand control lever, a hand holding the steering wheel of the new situation, many inexperienced drivers at this time will care for this and lose that ability to cope with unexpected events, large decline, anti had created a traffic safety hazard. At the same time, when the car slows down, it also needs to remind the back of the vehicle, which requires the driver to step on the brake board so that the brake light is on. Otherwise, in the case of not stepping down the brake pedal, forcibly pull the gear, slow down the car, the vehicle does not follow the driving situation behind, it is prone to traffic accidents
