После длительной эксплуатации автомобиля It is necessary to pay attention to deviations in the work of the main node - the engine. It is important to know how many revolutions should be idling. This problem is more relevant for carburetor cars with manual adjustment. But often electronic ignition systems fail for a variety of reasons.
When should adjustments be made?
After some manipulation with the auto is recommendedbe sure to check how many revolutions should be at idle speed. One of the reasons for changing the readings of the tachometer is the replacement of candles and oil according to the planned inspection. Similarly come after washing the fuel system, repair engine components, electronic components.
На любой СТО могут подсказать, сколько должно be speed. At idle at domestic engines the permissible values of the tachogenerator are in the range of 800-1000. The ideal system supports the arrow near the 800 mark.
Если рассматривать, сколько должно быть оборотов at idle with foreign cars, then you can pay attention to the instrument panel - there are no tachometer indications at all. At SRT, these values are checked using a diagnostic connector, displaying information on the screen of a laptop or a device specially designed for this purpose. It should be remembered that the stability of the engine depends on the quality of gasoline poured into the tank.
Recommendations
Any motorist with experience in repairing Sovietauto knows how many revolutions must be idling. The advice of specialists converges in one thing: during normal operation of the engine during the plant, the revolutions stay just above 1000, after warming up they drop to 800. If these indicators are not specified, the first thing they do is try to change the gasoline to a high-quality one.
It is recommended to check the operation of the candles, so that allpistons participated in the movement of the car. Many owners of domestic cars use balloons for cleaning the ignition system. Others resort to grandfathering methods - add 50 ml of naphthalene to the tank each time after refueling. The sale is EKTO gasoline from the company Lukoil, which has already been added similar additives.
Choosing the right brand of gasoline, you can saveits auto from future problems. Practice has shown that additives help keep the ignition system in perfect purity. Unsealed nodes did not have deposits on the walls even after several years.
Ignition system
Considering in detail the principle of functioningengine, you can understand how much there should be revolutions at idle. Useful tips help to solve some problems, but the car is a complex technique and requires a competent approach to periodic maintenance.
Important points in the operation of the ignition system:
- Принцип сжигания топлива лежит в образовании sparks at the moment when the engine's pistons are at the top point. If this does not happen in time, then an imbalance in idling starts.
- Важен так называемый угол срабатывания зажигания.If the electrician is faulty, it shifts, accordingly, one or several cylinders start to brake the rotation of the crankshaft. The thrust of the engine is lost, the car starts to accelerate slightly.
- Increased turnover is often associated with wedgingthe gas pedal cable, often the owners forget to lubricate it periodically. Similar problems are observed on cars with tachometers connected by a cable ligament.
Emerging issues
Each type of car has its own requirements and methods.determining how much idle speed should be. The principle of operation of the engine is based on a balanced movement of rotating nodes. Values of 600-1000 are in some sense optimal for all types of motors. However, manufacturers can change this parameter depending on the type of fuel consumed, the principle of operation of all systems as a whole.
The quality of air entering the enginedirectly affects his work. Changing the filter element is a measure of prevention to normalize the idle speed. Not be redundant and check the status of the fuel system filter.
Owners of used cars should be consideredthe degree of contamination of systems when using poor-quality gasoline in the past and switching to fuel with additives. The latter instantly dissolve the dirt on the walls, the tank, and it rushes directly into the area of the pistons, the injection system. This may cause instability of the motor, an unscheduled cleaning of these components will be required.
