A spark plug, NGK s, okay

1. General spark plug problems will lead to poor engine work, such as difficult starting, unstable idling, poor acceleration, urgent refueling and tempering, excessive exhaust gas, and increased fuel consumption. If the carbon deposition in the engine is serious, the valve will not be tightly closed, so that a cylinder will not work completely because there is no cylinder pressure, and even stick the valve to prevent it from returning. At this point, the valve and piston will interfere with the movement, which will eventually damage the engine.

It can be seen that the impact of carbon deposits on the engine is very large.

Second, the solution.

1.When unplugging the high-voltage wire joint, it should be gentle, and the spark plug insulator should not be shaken vigorously during operation, otherwise the spark plug sealing performance will be damaged.

2.The engine can be disassembled only after cooling, when the spark plug to be removed is loosened, blow the dirt around the spark plug one by one with a thin hose, and the dirt falls into the combustion chamber after the spark plug is unscrewed out.

3.The screw area, spark plug electrode and gasket must be kept clean, dry and free of oil stains, otherwise it will cause leakage, air leakage, spark weakening and other failures.

4.When installing, first use the sleeve to align the spark plug with the screw hole, gently screw it in by hand, screw it to about 1 2 of the full length of the thread, and then tighten it with an afterburner lever. If the hand feeling is not smooth when twisting, you should exit to check whether there are any entrained impurities in the screw mouth or thread, and you must not blindly tighten it, so as not to damage the screw hole and affect the cylinder head, especially the aluminum alloy cylinder head.

5.It should be tightened according to the required torque, too loose will cause air leakage, too tight will make the gasket lose elasticity, and it will also cause air leakage. Since the tapered spark plug does not use a gasket, it is particularly important to comply with the tightening torque.

6.When the carbon deposit and oil accumulation on the spark plug are not very serious, you can soak it in gasoline or kerosene and acetone solvent, and after the carbon deposit is softened, brush the carbon deposit on the electrode and the porcelain core and the cavity of the shell with a non-metallic brush, and dry it with compressed air. After cleaning, the spark plug is checked for clearance.

3. Preventive methods.

After completing the above, the installation test will be carried out, and the owner will be reminded to do regular maintenance to keep the oil and gas circuits clean; It is recommended to clean the air grid every 4000-8000km (according to the use of the vehicle and the actual situation) (replace it according to the actual situation), clean the throttle once, and clean the fire nozzle; Every 15,000-25,000km (according to the use of the vehicle and the actual situation), clean the intake pipe, throttle combustion chamber and related oil circuits, check the gasoline grid and replace it according to the situation; Avoid idling and stopping for a long time, avoid turning off the engine immediately after high-speed driving, avoid high-speed driving immediately after starting, and avoid low-speed gear shifting.

NGK spark plug** in the tens of yuan to hundreds of yuan. NGK spark plugs are also divided into several types, and the ** of different models and different materials are different. The function of the automobile spark plug is to send a pulse high-voltage electrical discharge from the high-voltage wire (nozzle wire) to penetrate the air between the two electrodes of the spark plug and generate an electric spark to induce the mixed gas in the cylinder.

The products are divided into standard spark plugs, insulator protruding spark plugs, etc.

When purchasing, you can't just consider the best aspects, whether it is a pole-burn iridium spark plug or an NGK spark plug, the most important thing is to suit your car.

Types of automotive spark plugs.

1. Standard 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. Insulator protruding spark plug: The insulator skirt is long and protrudes 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. Fine electrode spark plug: The 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.

NGK spark plugs are also divided into several kinds, different models, different materials are different, in a treasure is generally more than ten yuan to hundreds of yuan. Of course, when purchasing, you can't just consider the best aspects, whether it is an extreme iridium spark plug or an NGK spark plug, the most important thing is to suit your car.

It depends on what kind of price you use, ordinary 12 resistors, 20 platinum 75 [car problems, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

NGK spark plug production and sales headquarters are located in Nagoya City, Aichi Prefecture, Japan. Founded in 1936 and with a history of 67 years, Nippon Special Ceramics has been engaged in the production and sales of NGK spark plugs, oxygen sensors for internal combustion engines, knock sensors, etc., as well as the production and sales of ceramic products for semiconductor components and machine tools. NGK ranks first in the world in terms of production of spark plugs and oxygen sensors.

Currently, there are four manufacturers in Japan, North America (the United States), South America (Brazil), Europe (France), and 10 countries including Southeast Asian countries, as well as technical centers in Japan, North America (USA), South America (Brazil), and Europe (Germany) to develop spark plugs and oxygen sensors. At present, representative offices have been set up in Shanghai, China and Guangzhou, Guangdong Province, and the plant in Songjiang Industrial Zone, Shanghai, is scheduled to start production in the fall of 2003, considering NGK spark plugs for automobiles, motorcycles, general engine manufacturers and repair markets.

NGK spark plug is headquartered in Japan, a world-renowned spark plug company!
