Spark plugs ("GAZelle"): selection, installation, adjustment

Many car owners do not pay enough attention to the candlesticks. But they affect engine performance and are an integral component of the ignition system. Resource data elements is on the order of 50-60 thousand kilometers. After this period you need to replace the spark plugs. For ‘gazelles" (405 engine-injector) you can choose different types. But how to make the right choice? In today's article we will look at what are the different candles and what are the characteristics of each type.

Dimensions

This is the most important parameter. If he doesn't pay attention to spark plug (the‘GAZelle Business”) simply will not stand up to the engine. Also, pay attention to the length of the electrode. At excessively large sizes, it would hit the piston. The motor does not become worse, but candles have to be thrown away. If too small, the electrode will not reach the combustion chamber. Ignition will be difficult. The sizes should be the same as the old.

Glow

Buying the spark plugs on a “GAZel-405" pay attention to this parameter.

The Surface number indicates the heat mode of operation. The higher the score, the better. On the 405 the engine it is recommended to use spark plugs with higher nitro. This motor is a souped-up analog 406. At the moment, the glow indicator number can be from 11 to 26. Below, we present thermal characteristics:

• Heat rating of 11 to 14. This so-called hot plugs. They are used on malapportioned engines. In such power units, self-cleaning of the electrodes takes place at low temperatures. When used on boosted motors, they are quickly covered with soot.
• Heat rating from 20 to 26. These include cold candles. Mainly used for uprated and turbocharged internal combustion engines. At maximum power requires less heat for self-cleaning of the electrode.

There are Also standardized candles. Their setting ranges from 11 to 20. They can also be used on engines at Zavolzhsky engine plant.

Move on to the next feature. By number of electrode there are single - and multielectrode spark. Let's look at their characteristics in more detail.

Single electrode spark plugs

The‘GAZelle” it is equipped with such elements. Their design is very simple. Top is white ceramic case, and the bottom – glass with metal thread. Includes Central and side electrode, due to which spark is produced. Their diameter is 2.5 mm. The main advantage of such candles – is low cost. But there are drawbacks. If you have a boosted engine, they will not be able to unleash the full potential power. Also they are less durable than their counterparts.

Among the manufacturers should pay attention to the company ‘BOSCH", "DENSO”, “Take” and “champion”. Regarding the latter, there is used the copper electrode (and both Central and lateral). Because of this, significantly reduces the heating elements. Their resource is much higher analogues.

Also note the manufacturer NGK. What are these spark plugs ("GAZelle") price? The cost of a set of candles from this manufacturer up to a thousand rubles (four-cylinder). Product feature – the availability of special Central electrode. He is sawn in half, which significantly reduces the risk of fouling. And if there is, the spark will strike at the second electrode (more precisely, half). Judging by the reviews, these items are of high resource and have the best spark.

As for "DENSO" of the manufacturer “raspolovinit” only the side electrode. But most prefer to use NGK products.

Multielectrode

Unlike the first type, where they tried to split a single electrode, there is used from 3 or 4 element. We will note the main advantages:

• Best sparking. Due to the presence of more number of lateral electrodes, the deposits on one of them is not a hindrance.
• Available both cold and hot elements.
• Self-ignition of the fuel takes place strictly in the center.
• Ideal for uprated engines, so as to better burn the fuel in the cylinder chamber.

On the downside to mention is the higher the price of these spark plugs. "GAZelle" is a commercial vehicle, therefore, to choose a compromise. Many use the first type of candles, but only the one in which the electrodes are divided into two parts. But if you decide to purchase more sophisticated and expensive type, you should pay attention to producers "brisk", ‘Bosch’ and NGK.

Resistor

When buying a new set of spark plugs please note the presence of the resistor. If the ceramic part contains the letter R, this is a good sign.

These candles are protected from breakdowns and, consequently, will last much longer. Their price is 10 percent higher than normal, but it is expensive – say reviews owners.

Gas

You've Probably heard that there are specialized gas candles in the "GAZelle". Gas has higher octane, unlike gasoline. And suchcandles have the feature. Their electrode is much thinner than usual.

But whether their use is mandatory if the vehicle is fitted with LPG? As practice shows, regular candles with a thick electrode excellent job with their work. Therefore, you should not pay for the gas of candle. The more that the machine requires a good warm up on petrol.

What to choose?

So we figured out what are the spark plugs. "GAZelle" for commercial air transport, should be profitable with minimum investment. As for buying new candles, experts advise to pay attention to the one-electrode from the company NGK. It is desirable that they were with a resistor. The electrode should choose fat. A guarantee of a good sparking. And the presence of a forked electrode – a big plus.

Installation

For this you need a candle key. It looks as follows:

It is Not necessary to purchase products with a ready pen. It quickly breaks down – say reviews owners. As leverage, you can use a screwdriver, threading it into the hole. So, how to remove spark plugs? "GAZelle" pre-placed on the transmission. Next you need to remove high-voltage wires. They removed over a thick base.

Do Not pull the wire itself. So you'll damage the element. Remove old, install bought candles in place. Tighten the effort of one hand. If you overdo it you can strip the threads. Do not pull the key strength.

Next install back buenaposada (same basis) and proceed to the next cylinder. Please note that you need to remove them in turn. Otherwise you don't specify which wire was responsible for a particular cylinder. So, put everything back on and check the operation. Usually, new spark car starts with half turn. The installation is now complete.

Alignment

Over time you want to check the spark plug gap. "GAZelle" is under load. And sometimes candle can not give the desired spark. If the machine is stopped normally “pull”, you should remove the candle and check the gap between the electrode and the ground. It should be between 0.8 to one millimeter. Checked with a special dipstick (which expose the gaps in the valves). If the value is above normal, you can restore it. How to do it? The electrode on the plugs is very flexible, so you can bend it by tapping on a metal or plastic part of the engine (e.g. valve cover). Light blows, you will restore option. If ‘overdone" no problem – to increase the clearance with a screwdriver minus thin.

Operation

Over time, check the candles on the presence of plaque and watch for clearance. If the operation of these elements are nursed for 60 thousand. When it reaches this mileage change the spark kit on the new one.
