Contrary to what some imagine, using the brake-motor does not cause damage to the clutch system. On the contrary. The practice of using the proper functioning of the engine to reduce or control the speed of the car helps keep it under control. Now, the addiction to leave the foot on clutch, but can lead to wear. To take these and other questions, check out the answers to the questions of the Internet:

What and how the engine brake? Fabio and Sebastian - The brake motor is nothing but the practice of using the proper functioning of the engine to help reduce or control the speed of the car. For example, on a road the driver is in fifth gear when the fall comes. Then you take the foot off the accelerator and let the car follow the trajectory. At the time, only the fact release the accelerator pedal and let the car engaged in lowering the driver is already applying the use of the brake-motor. But the term is used when on long downhill, the driver also seeks to avoid excessive use of brakes to avoid the fatigue of the system by heating. Thus, the driver reduces a gear or two and let the car take the fall and use the brakes sparingly. The fact of reducing one or more gear causes the rotation of the engine to protrude while will impose a controlled speed to the car. Down with the car ungear or, as many say, in banguela, is a practice not recommended. In summary: keep your car always engaged, even on downhill, and with the brakes, so the driver is always driving in a safe and peaceful.

Often used in the brake-motor road, but after a year traveling with a stretch of 100 km with 48 spine, had to replace the clutch. The mechanic told me that the disk spent because the use of the brake-motor. Correct? Nélio Straw - Certainly the use of motor-brake does not cause damage to the clutch system. The brake-motor, as explained in another question above, is the way it should be. The car was designed for and that this practice serves to keep the car under control. In the case described the problem was the excessive use of the clutch, possibly in the spine. Some drivers tend to leave the foot in the clutch more time than necessary, especially in the up slope and, as in this case, the crossing of spine. It is commonly called a "burn clutch. The correct is get the foot of the clutch as it accelerates. Then, the foot should be supported on the side and not the pedal. It may seem obvious, but look at yourself repair or when the ride. Note another driver and see how the foot is resting on the clutch pedal. Another fact that is destroying the clutch during a stop at the traffic lights. The driver who uses the clutch and brake component is spending unnecessarily.

What are the rounds of the engine? Maria - The engine is composed of several moving parts inside. These pieces are a movement internal to the motor in place and this movement is called by spinning the engine. Thus the spinning of the motor are represented by rotations per minute (rpm), which means how many rounds the internal parts are every minute. When you hear that the rotation of the engine is 5 thousand rounds, that means operating the engine at that time is a system of the 5 thousand rotations per minute. To get an idea applicable in practice, at slow speed, or the engine running, but the car stopped, the rotation will be between 1 thousand and 1.5 thousand rounds.

How to spin some of each turn and when to change them? Vitor Pinto - Each car has a nice ideal to best use the engine, either performance or economy. It varies by fuel type, engine capacity and so on. There is a general rule, but in any case need to be aware of speed limits. Therefore, a path whose speed limit is 60 km / h more appropriate for most cars is accelerating the first to somewhere around 2500 rounds or rpm (revolutions per minute) of the engine and move the second motion. At the time, the rounds should fall slightly, thus speeding up until the third pass and again in 2500, following so on until the fifth gear. Using this method can accelerate up to around 3000 rpm. The tip is more suitable for cars with alcohol or gasoline. For diesel engines the rotations are smaller. If your car has to cute, you can build the speed too. When leaving the first to use 15 or 20 km / h, move to the second turn and go up to 30 km / h. Place the third and accelerate to 40 km / h or 45 km / h when they should be placed on Wednesday. To use the fifth gear, the best is only after the 60 km / h, so you should put it only where the speed limit is above the average.

Leave the car ungear means a drop in fuel economy? Igor - If the question is just economics, but we must develop a broader view of the matter. In absolute terms, a car with a carburetor that saves more fuel condition yes, but we must consider the risk. Is it worth it? Once a deviation is necessary to track or even a parade of emergency, the car is not under control is being engaged as a march. But as the issue is about economics, it is worth putting the tip of the pencil the excessive spending that driver will have with the brakes. At best the brake will not failures in routine use, but will require replacement of their canvases or pads and discs, before the hour. It is what we call the economy silly.

The use of the brake-engine damage the engine on a steep slope? Natanaildo
When the driver takes a long descent the right to leave the car is following the trajectory under control. Practice of the brake-motor driver that is running low, but it should be noted that the turns are high, more than necessary. For example, if the driver is a drop in the road in fourth gear at a speed of 70 km / h car is within range of their normal work. But suppose that the third driver to reduce motion and keep the speed. In this circumstance the rounds will increase greatly, requiring much of the engine unnecessarily. It would be the equivalent of stretching the marches. In this case, to reduce and put the third march would be required to slow to less than 60 km / h.
The correct is to use the brake-motor, but to the march right on time. How is this done? If your car has mind-spinning, look at the rotation. In this example, the 70 km / h in fifth gear, the marker was between 2.5 and 4 thousand rounds as the model and engine. When the drop take the driver puts the fourth march. The rounds up to a range between 3 and 4.5 mil. So far everything within the parameters, but the driver put a third and keep the speed, there would extrapolate the rounds, going for 4 to 6 thousand rounds. If your car has to look nice, the speed and the engine growl. If, as it reduces the marches, the snoring is raising too will need to reduce speed to stay within the scheme of work suitable for the engine.
The brake-motor is to assist you in long slopes, so use should be consistent with the speed. In the case above, the correct move would be decreasing as the speed and reduces the motion, the speed is reduced. This is correct way is safe to drive.
