Effective car acceleration
The main mistake is the slipping of the drive wheels (when the car is stationary, and the drive wheels rotate). If on any surface, whether asphalt or ice, you do not allow it, then consider that you already own a piece of skill. How to learn this?
On a flat road, preferably on an unloaded car (with a manual transmission), at idle, turn 1st gear and start the first movement without pressing the accelerator pedal at all, i.e. working only with the clutch pedal. When the car starts moving (idle speed), stop it by “pressing the clutch” and repeat again. It turned out? Try the same thing, but using 2nd gear. Do not overdo it! Two or three times happened – enough!
At such a start of movement, your drive wheels will not slip – there will not be enough engine power and, in extreme cases, it will simply stall. In ordinary life, we, of course, will not start the movement like this, except in rare cases when it’s very slippery. The conclusion is simple: the lower the engine speed at the start of movement, the greater the likelihood that there will be no slipping! In order to make the car easier to start moving, the front wheels must be set strictly straight!
But how can one accelerate quickly on slippery ice? More about this below.
The beginning of the movement or “acceleration”, to put it simply. Many will even name the necessary terms — weather tires, a powerful motor — and they will be right, but only partially. What else is important to know, and most importantly – to be able to?
We dare to remind you that the main mistake is, firstly, the driving wheels of your car skidding in place. The car is not located in a straight line with respect to the direction of movement, and the front wheels are turned (do not stand strictly straight). This is the second. How to learn to feel the beginning of slipping? A simple exercise, with the beginning of movement without “gas”, we think, did not cause great difficulties.
Lesson two. Subtle sensations
The car stands with the engine running on level ground. Engage I gear and slowly release the clutch pedal. There will come a moment when your car, before you start moving, as if “straining”. Pay attention to this, try to feel it.!
After the moment of “tension”, if you release the clutch a little more, movement will begin. But, as soon as the car makes a rush to move, and the wheels turn slightly, press the clutch exactly enough so that it stops and the “tension” is eliminated. Performing this non-stop, you will swing the car on the spot. The smaller the amplitude, the better! Ideally – the tires are in place, and the rim barely noticeably turns back and forth.
Exercise can be performed anytime, anywhere, it is absolutely safe. Now you know exactly how your grip works and in what range. By the way, all of the above can be done on a car with automatic transmission.
The next stage of training and sensations. The car stands still, you increase the engine speed to any value (for example, 2.500 rpm.) And hold it for a long time. It is better to do this by looking at the instrument – the tachometer, if there is, and if not, then by ear. Your task, by turning on I gear, start moving while holding the engine speed that you set before. From the beginning to the end of the exercise, the turns are the same – they do not fall and do not rise. Doing it all the better on the site, where there is no movement of cars and pedestrians. At the first attempts, it is better to look at the tachometer, again, if there is one. You need to start with a slight increase in speed and, as you complete it, complicate the task by increasing them. It is important to pay attention to the speed of releasing the clutch pedal, namely: try to do this as soon as possible.
If everything is done absolutely correctly, then the car accelerates quickly and without slipping, and the higher the engine speed that you hold, the faster. There comes a time when the execution becomes impossible due to the occurrence of slippage. Most often, this means that for a given pavement you have crossed the line and the engine speed is too high. The conclusion is simple: the higher the coefficient of adhesion, the greater the speed for quick acceleration we can afford! Performing acceleration in this way, you begin to catch the beginning of slipping, if you make a mistake – this is the uniqueness of the exercise.
Acceleration tricks and the start of movement
1. If you need to win the “start”, then the maximum form of your readiness for this is when the engine speed is chosen correctly, the front wheels are straight, and the car swings slightly in place (see Exercise above);
2. At the beginning of the movement, the center of gravity of the vehicle shifts back, loading the rear wheels. If a car with rear-wheel drive, this increases the acceleration efficiency, and if with a front-wheel drive it lowers (front, driving wheels are loaded). Using the rocking technique in place, i.e. moving the car back and forth, you and the center of gravity move back and forth. Using its movement (depending on the type of drive of your car), you can increase the efficiency of the starting moment, and even on very slippery roads start moving without slipping.
