How many revolutions should be idling and how to regulate them?

After a prolonged use of the carIt 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.

At any SRT can tell how much shouldbe 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.

If we consider how many revolutions there should beat 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 deviate from those indicated, they first 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:

• The principle of burning fuel lies in educationsparks 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.
• The so-called ignition angle is important. 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 methodsDetermine how many revolutions should be idling. The principle of the engine is based on a balanced movement of rotating nodes. The values ​​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 operating principle of all systems as a whole.

The quality of air entering the engine,directly affects its operation. The replacement of the filter element is a preventive measure for the normalization of idle speed. It will not be superfluous to check the condition of the fuel system filter.

Owners of used cars should take into accountthe degree of pollution of the systems when using low-quality gasoline in the past and switching to fuel with additives. The latter instantly dissolve dirt on the walls, the tank, and it rushes directly into the area of ​​the pistons, the injection system. This can cause unstable operation of the motor, you will need an unplanned cleaning of these units.
