How to clean spark plugs from carbon deposits yourself

Spark plugs are a key element of a car's ignition system. The devices have a significant impact on engine performance and fuel consumption. During operation of the equipment, candles are subjected to high temperature loads.

Accordingly, carbon deposits form on the working surface, which negatively affects the operation of the ignition. In such cases, cleaning or complete replacement of the spark plug is required.

When should you clean candles?

The need to clean spark plugs arises when there is a significant mileage or there is a malfunction in the vehicle's power system. In case of problems with the intake, dense black deposits may be present on the working surface.

Incorrect fuel mixture settings negatively affect the operation of the entire internal combustion engine. Excess fuel does not burn in the cylinders and leaves behind a black deposit.

Accordingly, the normal operation of the engine is disrupted, spark efficiency decreases and the load on the valve mechanism increases.

Also, abundant soot formation occurs on engines with worn piston or on cars that use low-quality fuel.

Common signs of faulty or fouled spark plugs:

1. Engine tripping at idle at 900 - 1500 rpm

2. Increased fuel consumption in normal driving mode

3. Loss of car dynamics during acceleration

4. Engine vibration and increased noise

5. Popping sounds in the muffler at rpm above 3000

6. Problems with ignition settings

7. The smell of gasoline in the area of the engine and muffler

You can check the operation of an individual spark plug by simultaneously removing the spark plug cap from each cylinder.

For safer and faster removal of the part, use a special lubricant for mounting liquid moths. Using the product will prevent moisture ingress and corrosion.

Any change in the operation of the internal combustion engine indicates that the ignition part is working properly.

It is better to check this way only on a carburetor car.

The injector has high-voltage coils, which can burn out if the spark plug is suddenly turned off. Therefore, if you have the listed symptoms, it is better to seek help from the service.

At the station, specialists will check the spark plugs using diagnostics at the stand.

Troubleshooting

To understand whether they are filled with gasoline or not, whether there is carbon deposits on them or not, you need to do a small and very simple procedure. To do this, prepare only two tools: a special spark plug wrench and pliers.

Turn on the ignition and unscrew the spark plugs. All modern cars typically come with one per cylinder, meaning there are exactly as many of them as there are cylinders in your car's engine.
Disconnect the unscrewed spark plug from the wires and unscrew one after the other.
Inspect them all for moisture, carbon deposits and a strong smell of gasoline. If everything listed is present on them, then they need to either be replaced with new ones or cleaned by calcination, which is what we are going to do.

Do-it-yourself cleaning with vinegar

Cleaning spark plugs with ordinary vinegar is not a popular method, but compared to a wire brush or sandpaper, the technique is considered more effective and safe. Each spark plug has a core called an electrode.

This part of the part is responsible for the formation and direction of the spark. Over time, the electrode becomes dirty, which significantly impairs the ignition of the mixture. Accordingly, thorough cleaning or purchasing a new set of spark plugs is required.

Vinegar cleaning method:

1. Select a container for one or more candles

2. Pour 9% (table) or 70% (technical) vinegar to the height of the metal part of the candle

3. Place the container in a dark place for 12 hours or 24 hours (depending on the degree of contamination)

4. After standing idle, clean the candles with an ordinary toothbrush

5. Wiping and drying parts after impregnation in acetic acid After the cleaning procedure, it is important to thoroughly dry the spark plugs before installing them on the car.

Unlike other methods of removing carbon deposits, soaking in vinegar is safer for the electrode. After all, each spark plug from the factory has a special coating, which is designed to avoid accidental breakdown and leakage of current to the block.

When mechanically cleaning with sandpaper or a wire brush, this coating is deformed. In this case, the spark plug may reduce its efficiency or completely fail.

Why are the candles on the trimmer burning?

What to do when gasoline trimmers do not start?

A gasoline trimmer is a surprisingly useful tool with which you can mow not only a small clearing in front of your house, but also an entire large lawn. Unfortunately, there is nothing endless in this world, and therefore you may encounter the fact that gasoline trimmers do not start.

Some reasons

It often happens that users of this type of car try to “save money” by filling the tank not with fuel with a regular octane rating, but with something incomprehensible that has been sitting in a plastic canister for almost a decade.

Main. fuel mixture!

In this case, the remnants of plastic dissolved in a brutal environment do such terrible things in the combustion chamber that you definitely won’t be able to do without a complete overhaul of the mechanism. But you will definitely forever remember how to properly store fuel.

Perform a cold start correctly!

Often, gasoline trimmers do not start after they are tried to be “put into operation” after long-term storage. Launch failures in this case are often caused by incorrect user actions.

If you are faced with this particular phenomenon, then during a cold start you need to close the damper, and then pump a small amount of the fuel mixture into the carburetor. Then pull out the starting handle until you feel resistance, then start the trimmer with sharp and vigorous movements.

Petrol trimmer. Wet candle. The engine flooded.

How can you drown the engine on a lawn mower if you are not careful? Just one awkward move

After a few jerks, it will start and stall, which is normal. Having moved the damper to the working position, start the tool again and start working.

More reasons

And again the carburetor.

If even after such abuse your trimmer does not start, you cannot do without disassembling the carburetor. It may very well be that the needle getting stuck in it is to blame. In any case, disassembling and washing this capricious mechanism certainly won’t hurt.

In general, when the trimmer begins to act up and stall, it is advisable to carry out complete prevention: completely change the fuel mixture, try a different oil, and also change the spark plug without fail. Practice shows that in many cases it is cheap, low-quality candles .

We looked at the most typical reasons why the trimmer does not start. If the problem is something more “exotic”, a trip to the service center cannot be avoided. You will probably find smaller and more obvious damage yourself.

Temperature range of spark plugs

The temperature of the spark plugs is also very important. It indicates the heating of their working part. Ideally, this range should be between 500-900 °C, based on the operating mode of the power unit. Moreover, regardless of the conditions of the combustion chamber. Whether it is idle speed of the internal combustion engine or maximum, the temperature of the spark plug must always be within the established norm. And this also applies to any type of spark plug.

This state of affairs is due to the fact that carbon deposits form on the insulator due to the low temperature. This in turn causes interruptions in the operation of car spark plugs. In addition, an increase or decrease in temperature negatively affects their service life.

Frequency of replacement of spark plugs

Each car enthusiast has his own approach to this issue: some change spark plugs along with an oil change, while others do not change them at all.

It is impossible to unambiguously give a figure for the frequency of replacement because it directly depends on the material of the spark plugs :

Copper/nickel spark plugs have a standard service life of up to 30 thousand km. , their cost is quite consistent with their service life, the price of one such candle will be around 250 rubles. I would change such spark plugs along with an oil change.
Platinum spark plugs (sprayed onto the electrode) are in second place in terms of service life, applicability and price tag. The duration of trouble-free operation of spark ignition is twice as long, that is, about 60 thousand km. In addition, the formation of soot will be significantly less, which has an even more favorable effect on the ignition of the air-fuel mixture.
Iridium spark plugs significantly improve thermal performance. These spark plugs provide an uninterrupted spark at the highest temperatures. The service life will be more than 100 thousand km , but the price will be much higher than the first two.

But you shouldn’t fall for advertising; even if you buy iridium spark plugs, no one guarantees you 100 thousand km. mileage

The frequency of replacing spark plugs largely depends on the condition of the engine and fuel , and in general, your car. If the car “eats oil”, then the spark plugs will fail much earlier than the declared service life.

Floating candles

Small floating candles are popular these days. They can add charm to your home decor or you can use them when taking a relaxing bath. How to make a new floating candle from old candles? Yes, very simple. Instead of a mold, you can use silicone ice molds with all kinds of figures. We pour the melted old candles into these molds, insert the wicks and the new candles are ready. At your discretion, you can give your candle any color and scent that will help you relax. These candles can be custom made to suit your taste. They can also be a wonderful gift for your friends.

Lavender candle

The pleasant lavender aroma is good for health, helps you relax, calms you down and relieves stress. So, in any home the presence of such a candle is welcome. You can buy such a candle in the store, but how nice it will be to enjoy the aroma knowing that you made it yourself. How to make a candle from an old candle and what we need for this.

First, dried lavender flowers and essential oil with a similar scent. Secondly, the container is up to your taste. We get liquid wax from an old candle. Place the wick in the container, pour in a little wax and lay out the dried flowers. Add oil and pour wax again. So, by alternating, we fill our candle. For aesthetics, you can make the wax purple. As a result, the candle will turn out to be very attractive and individual.

This method can be used to make candles with any scent. Dried orange peels, pine needles, lemon candles, mint or almond candles, etc.

I made this candle from the remnants of old ones (of different colors and shapes), using tetra packs and orange peel roses. When you light a candle, the orange peel begins to smolder and a pleasant aroma spreads throughout the apartment. If you don’t like this, then do not place the candle decor close to the wick and the roses will only decorate your creation.

So, we take unnecessary candles, a tetra pack (cut the bag at the top), orange peel roses, a wick (from an old or church candle). Having melted the candles in an old tin can, pour the paraffin into a tetra pack in different orders and different colors, allowing each color to cool. I alternated layers with paraffin crumbs (I grated the candle).

At the last stage, I placed roses made from orange peel around the perimeter of the tetrapak, as shown in the photo. When everything had cooled down, I cut the bag and took out the candle. Simple and fun)

You can make any decor that comes to your mind.

You can use just about anything to make a scented candle. For example, you can make a candle in any container by first placing cinnamon sticks and tea crumbs (any tea available in the house) on the bottom of the vase.

Having secured the wick on any stick, pour in the previously melted candles in an empty tin and let cool.

You can do it with all sorts of shells that you brought from the sea, but don’t know how to use...

Or with rose petals...

Or nothing at all, it’s just a pity to throw away the remains of burnt candles...

You can make your own ice candles!

Materials:

Wide shape for a future candle (you can use a cardboard milk bag)

Thin regular candle (household type)

Paraffin

crushed ice

Water bath pan

Container for melting paraffin

Pour water into the pan, place a jar of paraffin in it. Place several wooden sticks, for example, skewers for kebabs, on the bottom of the pan, and place the jar of paraffin on them. When the wax has completely melted, you can add finely planed wax crayons and flavorings to it for color.

While the wax is melting, prepare the molds for the candles.

Place a regular thin candle in the center of the candle mold. The form can be any.

Fill the area around the candle with crushed ice.

Use finely crushed ice: the coarser the ice, the larger the holes in your candle will be later on.

Carefully pour the melted wax into the prepared molds, trying to distribute it evenly around the ice.

Ice under the influence of hot wax will melt and leave small holes in the candle.

Once the wax has hardened (about 1 hour or so), pour the water out of the mold over the edge.

Leave the candle in the mold overnight and remove the candle from the mold in the morning.
Try to pull it out carefully so as not to damage the resulting openwork shape of the candle. In this regard, cardboard forms are more convenient - you can simply cut the edge of the box and then tear it. Leave the finished candle on a towel for another half day to dry completely. Now you have a candle that combines two elements: ice and flame! Source: About.com
