How to keep the engine speed? Helpful Tips

The internal combustion engine must always be in good condition. And if during the movement on the car jump speed, this is a very serious sign of a malfunction. Moreover, due to a sharp jump and a fall in the values of the tachometer, the car starts to absorb more fuel and at the same time it suddenly gloops suddenly. A big load is created not only on the engine, but also on the other units, therefore, if such faults are detected, it is not necessary to postpone repair to the last. In this article, we'll look at how to adjust and how to keep the engine's revolutions by hand.

We change the readings

To begin with, we will need to measure the number of revolutions of the crankshaft in order to know the degree of failure. For this, an ordinary tachometer is used, which every car has on the dashboard. By design, it is a kind of sensor that measures the speed of the shaft and displays all the indications on the scale with dividers. So, the normal values for cars are significantly different. For trucks with diesel engines, the norm is 1400-1500 rpm, for gasoline GAZel - 2000-2400 rpm, and in passenger cars this figure can reach the mark of 5 thousand. Therefore, it is impossible to find the ideal value for all machines. It is necessary to be guided by the readings of the "green scale" that every tachometer has. An exception are idle turns. Here the figure for all is equal - 700-1000 rpm. The question of what to do when the speed jumps at idle, we will consider just below.

What if the machine does not have a tachometer needle?

Sometimes manufacturers do not staff their cars with such sensors, so when measuring the speed, car owners are guided by a voltmeter. If the arrow of this unit jumps or goes to the red zone, this is a sign of unstable engine operation.

How to keep the engine speed at work and idle?

Having convinced of the wrong operation of the ICE, we proceed to repair. First we need to drown the air damper. Then use a screwdriver to get to the carburettor regulator and twist it until you hear a drop in speed. But how to keep the engine running, if this method was not effective? In this case, go to the idle sensor. If it is defective, be sure to replace it. Then again adjust the carburetor readings. If after 2-3 minutes the motor ceased to trip and stall, then the problem is solved. However, it happens that this does not save us from the problem. The last option is to replace the jets. Then the motor will definitely stop "taking off".

How to keep the engine speed with throttle?

There is another way, thanks to which it is possible to achieve the factory revolutions of the crankshaft. Do this only when the engine is in a cooled state. The damper smoothly reduces the speed, utaplivaya it. Then we look, that will be further. If the crankshaft rotates at an increased frequency, again go to the carburettor regulator. So do until the engine does not work properly. In time it will take approximately 1-2 hours.
