What kind of spark plug is good, what brand of spark plug is good

The original ordinary spark plugs are generally made of nickel-clad copper, with a service life of between 2-30,000 kilometers, and LDH iridium has a service life of 6-80,000 kilometers, and the electrodes are thinner and the ignition efficiency is higher.

Four-clawed or three-clawed.

Anyone who can jump sparks is good.

Although the spark plug is only a small part of the car, its role should not be underestimated, it has a close relationship with the engine, and its quality also determines whether the car can run normally.

Notes: 1) "Vehicle" refers to motor vehicles and non-motor vehicles.

2) "Motor vehicle" refers to a wheeled vehicle that is driven or towed by a power unit and driven on the road for personnel or for transporting goods and carrying out special engineering operations.

3) "Non-motorized vehicles" refers to vehicles driven by human or animal power and driven on the road, as well as motorized wheelchairs for the disabled, electric bicycles and other vehicles that are driven by power units but have a design maximum speed, empty mass and external dimensions that meet the relevant national standards.

There are many brands around the world, the most famous of which are Bosch, NGK, Denso, Suzuki, 3D, McQueen, Coolster, Honeywell, Otli and so on.

Spark plugs, commonly known as fire nozzles, are used to discharge the pulse high-voltage electrical discharge from the high-voltage wire, break down the air between the two electrodes of the spark plug, and generate an electric spark to introduce the mixed gas in the gas cylinder.

The main types are: quasi-type spark plugs, edge body protruding spark plugs, electrode type spark plugs, seat type spark plugs, polar type spark plugs, surface jump fire type spark plugs, etc. The function of the spark plug is to introduce tens of thousands of volts of high-voltage electricity into the combustion chamber, and generate an electric spark to ignite the mixture, and cooperate with the ignition system and oil supply system to make the engine work, which determines the performance of the engine to a large extent.

Bosch (Bosch), one of the products of the world's top 500 auto parts manufacturers, mainly used in German series models. However, due to the fact that Bosch has too many products and is not focused enough, the quality of its spark plugs in domestic OEM is uneven.

Jiburn, China's world's highest performance fuel-saving spark plug, compared with any spark plug brand, has great performance advantages in terms of fuel saving and power improvement.

The only national brand that has the potential to break the monopoly of foreign brands, but it is currently less well-known.

NGK, one of the best spark plugs in the industry produced in Japan, has a high reputation for quality and has captured a large market share in the world with Japanese cars.

The spark plug, although a small part of the car, has a very large role, and the engine ignition system introduces a high-voltage current into the cylinder to produce an electric spark, which ignites the combustible gas mixture.

The spark plug is mainly composed of a take-up nut, an insulator, a wiring screw, a central electrode, a side electrode and a shell, and the side electrodes are welded to the shell.

HKS Iridium spark plugs.

At present, the HKS spark plug products that can be bought on the market are basically products that correspond to the conditions of daily street use, and basically use iridium metal as the main ignition medium. Among them, the models include: S30, S30i, S35, S35i, S35IL, S40, S45, S45i, R45Re, R50Re, R525Re, R55Re, etc., although the suffix is more complex, but if the model is split and explained, it is clear at a glance.

"S" stands for Spark Plugs, which means spark plugs; The "i" after the number stands for ISO, which is the internationally recognized standard for calorific value, and the one without the "i" is the Japanese standard JIS. "L" indicates the model of lengthening the nozzle gap, because the ignition gap of the spark plug of some cars, such as the Audi model, is 11, which is larger than that of the Japanese model, if the choice is not right, the ignition will be poor during the vehicle, so you must pay attention to the ignition gap when choosing; As for "RE", it is a special model for rotary engines, and this model can be used in both the RX-8 and RX-7 currently sold in China. As for the number in the middle, it is the calorific value of the spark plug:

30: commonly known as a 6-degree nozzle;

35: commonly known as a 7-degree nozzle;

40: is equivalent to 8 degrees of products;

45: A product equivalent to a calorific price of 9 degrees;

50: It is a 10-degree product;

525: spark plug between 11 and 10 degrees;

55: is the highest level of 11 degrees for the street.

Hope it helps.

Foreign brands: Bosch, NGK, Denso, Adecco, Delphi, Honeywell, etc. are better.

Domestic brands: Hunan Torch, Ningbo Starlight, etc. are better.

BOSCH, also known as Bosch, is one of the largest auto parts manufacturers in the world today. Bosch has been producing spark plugs since the end of the 19th century and has been producing 8 billion spark plugs for more than 110 years.

Bosch is the founder of electromagnetic spark plugs, which has better performance than ordinary spark plugs, and is currently the original spark plug supplier of Volkswagen, Audi, Skoda and other German cars.

Precautions for automotive spark plugs.

It should be noted that when replacing a new spark plug, attention should be paid to comparing the length of the external threads of the new and old spark plugs. If the thread of a new spark plug is too short, the spark plug gap will be located in the recessed cylinder head, and the arc will be difficult or even impossible to ignite the mixture.

If it is too long, the overexposed bottom of the spark plug will overheat, causing pre-ignition, and the threads protruding into the combustion chamber will accumulate carbon, and the end of the spark plug may even hit the piston top. Some models have seals, while others do not. If the old spark plug that was unscrewed has a seal, then the new replacement spark plug should also be fitted with a seal.

Hello, I am helping you sort out the answer to your question, please wait a while Hello, at present, the spark plug with good quality and performance is the better quality of the spark plug Denso spark plug, NGK spark plug and Dr. spark plug are of good quality.

Questions. Which one is better for Changan to use NGK or Denso.

JD Denso is almost the same as NGK**, Denso said it was imported.

See. What's wrong.

Denso spark plugs and NGK spark plugs have better performance than Denso, but the same specifications are sure that Denso's is higher than NGK's, and generally modified cars will use Denso's spark plugs to improve their performance, and Denso spark plugs also have ordinary models and NGKIt's almost, just like Mercedes-Benz and BMW, you say that good has its own strengths, or there won't be so many car manufacturers supporting NGK spark plugs, and there are a lot of fake Denso spark plugs, which needs to be paid attention to.

Questions. Denso is double iridium for the needle.

**More than 3 hundred.

Denso spark plugs are not all double iridium needles, but also divided into models, Denso spark plugs are very good in performance, but the attenuation is relatively fast when used to a certain number of kilometers, that is, the performance is not as good as just replaced after a period of time, NGK's relative performance is a little worse than that of Denso, but the attenuation is better than Denso, how to choose these two brands depends on your own needs, spark plugs are recommended to buy in the official *** don't just look at ** quality is the first place, Especially if something goes wrong on the Internet, it's more troublesome.

If you're looking for performance, choose Denso, and if you're not looking for performance, NGK is a good choice.

Automotive spark plug brands are: NGK, Bosch, Denso, Champion, Torch, Acdelco, Autolite, 3D SW, Hella Hella, Newstars. These brands are good.

Different people will have different opinions on what brand of spark plug is best, such as Bosch, Jiran, and NGK.

The easiest way to eliminate it is to clean the throttle once, and if it doesn't work, you have to go to the repair shop to check. 1. Diagnosis method for idle switch not closing: turn on the air conditioner when idling, and turn on the steering wheel The engine speed does not rise, which can prove to be this fault.

Troubleshooting: Adjust, repair, or replace the throttle position sensor. 2. Idle control valve (ISC) fault diagnosis party.

Iridium spark plugs are the best, and so are the clear performance.

Iridium material has the characteristics of high hardness, high corrosion resistance and high melting point, and its spark plug performance is the best. Iridium is the most corrosion-resistant and wear-resistant, which can not only meet the needs of high-power engines, but also withstand high-temperature conditions, making the electrodes not easy to melt and damage. Correspondingly, its ** is also relatively high, and the nickel alloy spark plug is an ordinary type, which is only suitable for low-end models.

So the iridium spark plug is the best, and the performance is also the best.

Automotive Spark Plug Material:

The materials of automobile spark plugs also include nickel alloy spark plugs, platinum spark plugs, etc.

The service life of a nickel spark plug is related to factors such as electrode material, nickel spark plug brand, etc. Most ordinary nickel alloy spark plugs need to be replaced once after 20,000 kilometers of use, and the service life is the shortest. about 40,000 kilometers to replace platinum spark plugs; The iridium spark plug can be replaced for about 6-80,000 kilometers, and the service life of the bird is the longest.

However, these are only some reference values and depend on the conditions under which the spark plug will be used.

It is also necessary to pay attention to the maintenance of the spark plug during its use, which can prolong its service life and reduce fuel consumption. The maintenance of spark plugs mostly requires regular inspections, regular replacements, and regular cleaning. When it is found that the spark plug has carbon deposits, it can be soaked in kerosene for a period of time, slowly brushed with a fine steel brush, and then dried with compressed air before use.

The spark plug, commonly known as the nozzle, is used to discharge the pulse high-voltage electricity sent by the high-voltage wire, penetrate the air between the two electrodes of the spark plug, and generate an electric spark to draw the mixed gas in the cylinder. The main types are: quasi-type spark plugs, edge body protruding spark plugs, electrode type spark plugs, seat type spark plugs, polar type spark plugs, surface jump fire type spark plugs, etc.

The function of the spark plug is to introduce tens of thousands of volts of high-voltage electricity into the combustion chamber, and generate an electric spark to ignite the mixture, and cooperate with the ignition system and the oil supply system to make the engine work. According to the electrode material, there are nickel alloys, silver alloys and platinum alloys; If you are more professional, the types of spark plugs are generally as follows:

1. Quasi-type spark plug: the skirt of the insulator is slightly retracted into the end face of the shell, and the side electrode is outside the end face of the shell, which is the most widely used.

2. Spark plug with protruding edge: the skirt of the insulator is long, protruding beyond the end face of the shell. It has the advantages of large heat absorption, good anti-fouling ability, etc., and can be directly cooled by the intake air to reduce the temperature, so it is not easy to cause hot spot fire, so the thermal adaptation range is wide.

3. Electrode spark plug: its electrode is very thin, characterized by strong sparks, good ignition ability, and can ensure that the engine starts quickly and reliably in the severe cold season, with a wide thermal range, which can meet a variety of purposes.

4. Seat type spark plug: its shell and screw-in screw pattern are made into a cone, so it can maintain a good seal without gaskets, thereby reducing the volume of the spark plug and making it more beneficial to the design of the engine.

5. Polar spark plug: the side electrode is generally two or more than two, the advantage is that the ignition is reliable, and the gap does not need to be adjusted frequently, so it is often used in some gasoline engines where the electrode is easy to ablate and the spark plug gap can not be adjusted frequently.

6. Surface skip type spark plug: that is, along the surface gap type, it is the coldest type of spark plug, and the gap between the central electrode and the end face of the shell is concentric.

In addition, in order to suppress radio interference from the ignition system of automobiles, resistive and shielded spark plugs are produced. The resistive spark plug is a ceramic resistor with 5-10 ceramic resistors installed in the spark plug, and the shielded spark plug uses a metal shell to shield and seal the entire spark plug. Shielded spark plugs not only protect against radio interference, but can also be used in waterproof and explosion-proof applications.

Key features: The function of the fire ant bright plug is to introduce tens of thousands of volts of high-voltage electricity into the combustion chamber, and generate an electric spark to ignite the mixture, and cooperate with the ignition system and the oil supply system to make the engine work, which determines the performance of the engine to a large extent.

The main parts of a spark plug are an insulator, a housing, a wiring screw, and an electrode. The insulator must have good insulation and thermal conductivity, high mechanical strength, and be able to withstand high-temperature thermal shock and chemical corrosion, and the material is usually 95% alumina porcelain. The housing is made of steel, and its function is to secure the spark plug to the cylinder head.

The dimensions of the hexagonal threads of the housing have been incorporated into the ISO international standard. The spark plug electrode consists of a center electrode and a side electrode, and the spark gap between the two is the spark gap. The size of the gap directly affects the starting and power of the engine.
