Spark plugs are the most important element in the smooth operation of the engine, igniting the air-fuel mixture in the combustion chamber of a car engine. In most cases, the number of spark plugs corresponds to the number of cylinders in the car engine, but there are exceptions.

If there are any problems with the spark plugs, the entire engine system of the car begins to suffer, even if there is a problem with one of several spark plugs. The period for replacing spark plugs can be found in the car's service card, but if any problems appear with the engine, you should immediately replace the spark plugs. Mosavtoshina technicians strongly recommend replacing spark plugs in your car. Chery Tiggo every 15,000 km even when using original spark plugs.

The main task of spark plugs is to be able to withstand the highest loads. It is always worth remembering a simple rule: more expensive spark plugs will last much longer than their cheap counterparts. If there is a problem with the vehicle's propulsion system, replacement should not be delayed under any circumstances. Often a problem with spark plugs results in a "Check Engine" error.

Timely replacement spark plugs in Chery Tiggo will significantly increase fuel economy, saving money.

You should not replace the spark plugs yourself unless you are confident that the spark plug can be safely removed from the cylinder. Our service has special equipment at its disposal that allows for effective replacement in a short time.

After replacing the spark plugs with Chery car, our specialist will determine the main indicators of the condition of the internal combustion engine: the quality of the fuel used, problems with the engine, efficiency of the fuel supply.

Replacing spark plugs with Forza is not such a complicated procedure that you cannot do it yourself. At the same time, it is also included in the list of procedures for periodic vehicle maintenance, which means that you will have to deal with it regularly.

Replacement frequency and suitable spark plugs for ZAZ Forza

When to change spark plugs - it is recommended to check spark plugs on ZAZ Forza every 30,000 km, and replacement interval is 40,000 km. Or every 4 years. At the same time, on the Chery A13 this interval is slightly less - 20 and 30 thousand kilometers, respectively.

Which spark plugs to use - DENSO - K20PBRS-10, BERU - 14FR-7DTU, BRISK - DR15TC, NGK - BKPR6ET spark plugs are suitable.

Replacing ZAZ Forza spark plugs

Before replacing, it is worth blowing out the top of the engine with compressed air to prevent debris from getting into the cylinders.

First you need to remove the ignition coil cap, then unscrew the spark plug from the well using a spark plug wrench (with a magnet or rubber band). New the spark plug should be inserted back into the key, and only then carefully lower it into the well and tighten it tightly (tightening torque - 30 Nm).

This is how all the spark plugs are changed. How to change spark plugs with your own hands Forze can be seen in this video.

Despite its apparent simplicity, servicing spark plugs on each car has its own characteristics. And in addition to the type of spark plugs themselves, the required gap on them, there is also the concept of structural differences in car engines, which entails a different approach to the procedure for unscrewing spark plugs. We invite you to familiarize yourself with how to properly service spark plugs on a Chery Tiggo crossover.

According to the manufacturer's recommendations, regular spark plugs on the Tigo must be changed every 20,000 kilometers. If you have iridium ones, then in this case the frequency of their replacement can be increased three times. However, this does not mean that you can drive 20 or 60 thousand kilometers calmly and be sure that everything is still in order with the spark plugs: they need to be checked periodically, and it is better to do it yourself, elevating this procedure to the category of ordinary, at least - monthly, or even weekly. Well, if the time has come, then no matter that your candles still seem normal to you, feel free to buy new ones and start replacing.

The process of checking spark plugs in any case involves their removal. Therefore, having learned how to check spark plugs, you will also know how to replace them. So, on Chery Tiggo we do this operation using a 10mm wrench, a spark plug wrench with a rubber bushing (which holds the spark plugs in the wrench), as well as a special round feeler gauge or a set of flat feeler gauges (to measure the gap in the spark plug).

Now the coldest period of the year is coming - winter. And although checking spark plugs is a mandatory measure for year-round operation, especially in winter, faulty spark plugs cause the most trouble. Protect yourself from them - change the spark plugs promptly!

One of the service centers encountered the following problem: for one of the clients, the same spark plug constantly failed in the car engine. Approximately every three weeks, the client returned to the auto mechanic with a complaint about uneven engine operation. Idling and reduced power. Each time, the auto mechanic discovered a spark plug in the same cylinder with the central electrode almost completely burnt out. And every time, it was enough to replace this spark plug, and the engine began to work normally. After three customer calls with the same complaint, the service center foreman advised the auto mechanic to pay attention to whether the cause of this malfunction could be a loose spark plug in the threaded socket.

The auto mechanic admitted that every time he replaced a spark plug, he discovered that it was not tightly screwed into the threaded socket. A speck of dirt on the taper socket threads could also cause the spark plug to overheat (most of the heat from the tip of the plug is transferred to the cylinder head).

Once the spark plug was properly tightened, the engine ran fine and had no further problems. After returning the car to the customer, the mechanic admitted to the foreman that the constantly failing spark plug was in such an awkward place that it was difficult to tighten it to the specified torque, and the problem was his fault, not the engine.

To avoid over-tightening the spark plug, set the key's ratchet mechanism to two notches.

To avoid over-tightening the spark plug if you don't have a torque wrench, do it with a ratchet wrench. To do this, after screwing in the spark plug, pull it by hand to an angle corresponding to two clicks of the key ratchet mechanism. Even the strongest worker will not be able to tighten the spark plug in this case.

Install spark plugs of the brand preferred by the car manufacturer

At one of the non-branded service centers, a technician replaced the spark plugs in a Pontiac vehicle with new spark plugs that matched the old ones in size, heat rating, and thread length, and differed only in that they were trademark Champion. When the client came to pay the invoice for the work performed, he inquired what brand of spare parts were used for maintenance his car. After hearing that his vehicle had Champion spark plugs, the customer did not sign the check he had already written. He stated that he owned one thousand shares of General Motors stock, that he owned two General Motors cars, and that he would only accept General Motors parts. The manager of the service center had to order the technician to replace the spark plugs with new ones - the AC brand, since the spark plugs of this particular brand were originally in the car. Although spark plugs from different manufacturers are generally suitable for almost any engine, many customers prefer that their car engines have spark plugs of the brand preferred by the car manufacturer.

Chery Tiggo 2005. The main reasons for engine tripping

The ignition timing is incorrectly set.
- There is an air leak in the vacuum brake booster system.
- Faulty spark plugs. It is worth noting that this problem is the most common, since spark plugs need to be changed after driving a car every 20,000 kilometers (this figure depends on the recommendations given by the designers of each car).
- Breakdown of the high-voltage wire that goes to the spark plug.
- Faulty installed capacitor.
- Violation of the tightness of the system in the area of ​​​​the intake manifold.
- The appearance of burnout of one of the piston or valve.
- Breakdown piston rings, their deformation and wear also lead to this problem.
- Incorrect adjustment of the timing valves.
- High degree of rocker wear.
- Failure of the installed cylinder head gasket.
- Any type of wear (hardening, breakdown, destruction) of the valve stem seals.
- If the carburetor is adjusted incorrectly, the cylinders may also malfunction.
- Condition of the installed distributor shaft and rotary plate bearing.
- Clogging air filter.
- Loss of tightness of the membrane of the vacuum ignition timing regulator.
- Use of unsuitable spark plugs (not only the dimensions, but also other parameters of this element are taken into account) for this engine.

Engine troubles

Engine tripping is a definition that should be understood as a failure in internal combustion engine operation when one or more cylinders do not work partially or completely. To put it another way, the combustion process fuel-air mixture in individual cylinders is disrupted, which causes unstable operation of the engine at idle, under load and in transient conditions.

Engine trouble manifests itself in the form of increased vibrations of the power unit, and the engine noticeably loses power. Misfires may occur, which are accompanied by strong pops in the exhaust system.

The engine can stall either occasionally or constantly, only at idle or under load, cold, hot, etc. Next, we intend to answer the question of what engine tripping is, and also consider the main reasons why the engine begins to trip.

Why does the engine start to stall?

Engine tripping is a violation of the combustion of the mixture in the cylinders, which is accompanied by a clear increase in vibration. Please note that the appearance of internal combustion engine vibrations is not necessarily a tripping, since there are a number of other reasons why the engine vibrates strongly.

Main malfunctions resulting in engine tripping:
Supplying insufficient or excess fuel to the cylinder;
- supply of insufficient or excess air;
- malfunction of the ignition system, early or late ignition;

- wear or breakdown of the motor, which is accompanied by a decrease in compression;
In other words, the engine begins to stall as a result of an inappropriate composition of the fuel-air mixture, untimely ignition of the mixture or inability to ignite the charge, as well as violation of the conditions for normal combustion of the mixture as a result of mechanical wear or breakdown of the engine itself. Based on this data, you can narrow your search and the number of systems for diagnosis. The check should begin with fuel system

and injector, then the intake air supply and the ignition system are checked. In some cases, engine stalling may also be the result of a failure of one of the ECM sensors.

Engine troubles: ignition of fuel-air mixture is disrupted The most common reason that causes the engine to misfire is late or early ignition, as well as a weak spark plug. On initial stage

You should unscrew the spark plugs for a detailed inspection. If damage to the insulator or other defects is noticeable, then the spark plug should be replaced.
Next you need to check the spark plug wires. An indirect sign indicating this element is the occasional tripping of the engine in conditions of high humidity (rain, dampness, etc.). After warming up and the engine starts to operating temperature symptoms may disappear completely.

You should start by inspecting the spark plug cap and the highest voltage wire. These elements have rubber insulation, which tends to dry out and crack over time, as a result of which the wire begins to break through.
Also, the high-voltage wire or cap is often damaged during service or repair work in the engine compartment.
Let us add that the location of the breakdown may not be visually detectable. In this case, it is better to check this element of the ignition system using one of the available methods.

If everything is in order with the spark plugs and wires, then the ignition coil may be the culprit for the engine misfiring. On engines with separate coils for each spark plug, this phenomenon is especially widespread. To check the ignition coil, you need to unscrew the spark plug, apply it to ground and start the engine. Please note that the thread of the candle must tightly touch the mass, the cap must be tightly placed on the candle. Ignoring these rules may result in burnout of the coil or commutator. A good spark with a characteristic crackling sound will indicate the serviceability of the coil; the absence of a spark will indicate the need to replace the coil.

As for the electronic ignition distributor (switch), this element does not break down often. To check, the spark plugs are securely attached to ground, then the caps are connected to them, after which one person turns the engine with the starter, and the other evaluates the strength of the spark on the spark plugs.

Motor trouble: problems with air supply

Inadequate or excessive intake air can also cause cylinder misfire. The air supply system may lose its tightness and the engine begins to suck in excess air. The ECU does not take this leak into account, and as a result, the stability of operation is disrupted. Check

Lack of air often occurs due to a dirty air filter that has lost its capacity. The filter must be removed and the engine performance assessed after removal. There may also be insufficient air if the throttle valve is clogged or there is a problem with this unit. This element requires mandatory cleaning and inspection. It is advisable to do this at every scheduled maintenance in parallel with replacement motor oil, filters, etc.
Another reason for the engine tripping may be the TPS, mass air flow sensor or another sensor that sends an incorrect signal to the ECU. In such a situation, the control unit does not know to what degree the damper is actually open, how much air actually entered the engine, etc. Based on incorrect data, the “brains” cannot accurately calculate the optimal composition of the fuel-air mixture in relation to the dynamically changing operating modes of the internal combustion engine.

In this case, you should view the sensor readings and read the errors using a scanner that is connected to the vehicle’s diagnostic connector. Then the values ​​must be compared with the nominal ones. Deviations from the norm in the readings of the air flow meter or position sensor throttle valve

lead to the engine starting to stall.

Troubleshooting in cylinders: faulty power system

When checking the power system, you should pay attention to the following nuances:
Fuel pressure;

-air leak; Fuel pressure directly depends on the serviceability of the electric fuel pump, which on modern injection cars is located in fuel tank

. The device may have a clogged fuel pump filter, or problems may arise with the electric motor of the fuel pump or the power supply to the pump. It is also worth checking the pressure regulator valve in the fuel rail. Low pressure in the fuel supply system is often the cause of tripping. The next step is to check the injection nozzles. This element tends to become clogged, resulting in reduced throughput, disruption of the spray pattern, etc. Also, failure of the injector itself should not be ruled out. To clean and check the injectors, you can use a washing stand, on which a special solution is pumped through the device. flushing fluid

You can also check and clean the injectors yourself. To do this, liquid (for example, carburetor cleaner) is also pumped through the device. Power is supplied through simple diagram with a light from the battery terminal.
A working injector should not leak when closed. Also, the injector must open in a timely manner when an electrical impulse is applied. It is not allowed for the injector to pour fuel, since the efficiency of subsequent combustion of the charge in the cylinder depends on the quality of the spray.

If the fuel pressure and the injector itself are OK, then you should check the ECU. The control unit itself rarely fails, but it is possible. More often this happens in cases where the factory firmware was changed when installing an LPG or the engine was given software chip tuning.

Unprofessional manipulations with fuel maps can lead to the ECU overfilling the fuel and flooding the spark plugs.

Reduced compression in cylinders

A drop in compression indicates engine failure or wear.
