When you need to switch

The basic rule that you need to learn the switch to high gear should be carried out by the engine reaches a value of speed of rotation of its crankshaft is approximately equal to 3500 rpm. Why so and not otherwise? The answer is simple –torque of the motor (and its acceleration) increases until the time when his turnover reached the value of about 4000 rpm With increasing speed of rotation of the crankshaft over 4000 rpm torque increase does not occur, then the frequency at 5000 rpm and higher torque of the engine begins to plummet, despite the high fuel consumption and develop almost maximum power. Hard to believe? However, it is so. Doubters encourage you to read external high-speed characteristic of the motor, represented as a graph, where the curve of the torque with increasing speed first increases rapidly, then some time remains almost constant, and then steadily goes down. External speed characteristics of different motors may be slightly different from one another, however, the issue is not the switch to high gear to perform when the engine speed is approximately 3500 rpm.

Technique of working with the pedals and gearshift lever

After the set engine required to raise the transfer is necessary to release the accelerator pedal while squeezing the clutch pedal. Not waiting until the clutch pedal touches the floor, you need to disable the current transmission. And now attention! To give the synchronizers of a transmission time for the adjustment of the speeds of rotation of the gears after turning off the transmission will hold the gear stick in neutral position for about half a second-second. This does not mean that you want the transfer lever to the center position neutral. When switching from the first speed to the second, it helps to lock it in the neutral position between the first and second speeds. Including higher gear, left to release the clutch pedal to restore the link between the engine and transmission. Some drivers during this operation make the mistake of holding the clutch pedal down for some time after switching on higher transfer or releasing it too slowly. During this time, the engine speed will decrease significantly, and after the clutch because of a difference of rotation speeds of driving and driven disks, the machine will inevitably "bite his nose". To avoid this, release the clutch pedal should be one movement, not catching the moment of "grasping" as when starting from rest. This is done by slowly releasing the pedal without losing its contact with the foot. In other words – the leg should only be accompanied by the pedal, preventing its return to its original position under the action of a return spring. To continue will only have to press gently on the accelerator, giving the car acceleration. Anticipation is a legitimate question about how much time it should take for the procedure to change gear up, the answer is: exactly as much as needed to ensure that the engine rpm dropped from 3500 rpm to 2500. Having dealt with the right raising gear, pay attention and also competent gear down. Good luck to you! No nail, no wand!
