How to keep the engine speed? Helpful Tips
The internal combustion engine must alwaysbe in good order. And if during the movement on the car jump speed, this is a very serious sign of a malfunction. Moreover, because of 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 stalls 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 with your own hands.
We change the readings
To begin with, we need to measure the quantitycrankshaft turns to find out 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 for passenger cars this figure can reach 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 idling speed, we will consider below.
What if the machine does not have a tachometer needle?
Sometimes manufacturers do not staff their owncars such sensors, so when measuring the speed of the 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?
After making sure that the ICE is not working properly, proceedto 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 turned out to be ineffective? 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 that you canto achieve the factory revolutions of the crankshaft. Do this only when the engine is in a cooled state. The damper gradually reduces the speed, utaplivaya it. Then we look, that will be further. If the crankshaft rotates with an increased frequency, again go to the regulator of the carburetor. So do until the engine does not work properly. It takes about 1-2 hours by the time.
