Is a good spark plug fuel efficient?

Yes, a high-performance spark plug can improve the dynamic performance of the vehicle.

Normally, the service life of spark plugs is 15,000 km, and the service life of long-lasting spark plugs does not exceed 30,000 km. However, many car owners' spark plugs often have such and such problems, and their normal service life cannot be achieved.

Spark plug ablation.

When the owner finds that the top of the spark plug is scarred or damaged, and the electrode is melted or ablated, it indicates that the spark plug has been destroyed, and the spark plug should be replaced. During the replacement process, the owner can check the symptoms of spark plug ablation and the change in color.

There is sediment on the spark plug.

Deposits sometimes stick to the tip of the spark plug insulator and between the electrodes. Car owners should not underestimate this deposit.

In severe cases, this condition may cause the engine to not work properly. After cleaning the spark plugs, the vehicle can be operated normally for the time being, but a similar situation will occur soon after. In fact, the presence of spark plug deposits is only a superficial phenomenon, which may be a sign of a problem with other mechanical parts of the vehicle.

Hope the above is useful to you.

In general, as long as the electric plate of the spark plug receives the high-voltage electrical pulse of the ignition system and ignites the mixture in the cylinder, a spark will be formed and a deflagration will be generated, providing the energy required for the power output of the engine. At the same time, foreigners observed that the gap between the electrodes of ordinary spark plugs was nearly wider than that of platinum alloys.

Spark plugs do have a direct impact on the engine's fuel consumption. The gap between the two electrodes of the spark plug, the spark plug corona, the spark plug carbon deposit, the spark plug ablation, and the spark plug gas all affect the ignition performance, the spark plug ignition performance is good, the engine has no deflagration and detonation, the operation is stable, and the fuel consumption is naturally reduced, and the material of the spark plug directly affects the quality of the spark plug.

However, spark plugs are not always more expensive, and the one that suits your engine is the best. For example, a second-hand van of 20,000 or 30,000 yuan is used for 500 yuan to change the iridium spark plug, which is also not suitable, and there is no need to worship the iridium spark plug.

Si Youpu said that the car, a good spark plug can save fuel.

A good spark plug saves fuel. But it saves very little oil. The misfire rate is greatly reduced during hard acceleration or cold start, which means that there is no wasted oil, which is equivalent to fuel saving. The factors that affect fuel consumption and the ways to reduce fuel consumption are as follows:

Factors influencing fuel consumption:

Bad driving habits: drill when you see air, emergency stop, low-speed driving, high-speed driving, etc. will lead to an increase in the fuel consumption of the car.

Engine carbon deposits: Engine carbon deposits can also cause excessive fuel consumption. Low tire pressure:

Low tire pressure and under-inflated wheels can also contribute to a vehicle's fuel consumption. When driving, you may wish to check the inflation of the wheels, and the tire pressure can also be detected by the annihilation instrument. Trunk weight:

Too many items in the trunk can also increase your vehicle's fuel consumption.

Ways to reduce oil consumption:

When driving the vehicle, keep driving at a constant speed, avoid sudden braking, and maintain the vehicle regularly.

A good spark plug can save fuel, because the spark plug is made of good material, and the electrode is significantly thinner than that of ordinary spark plugs. The finer the electrode, the lower the ignition voltage, and in the process of cold start or rapid acceleration, the misfire rate will be effectively reduced, so that there will be no waste of oil, which means fuel saving.

The main difference between a good spark plug and a bad spark plug is the difference in electrode materials, among which the melting point of iridium spark plug is very high, and the center electrode is very fine, so that the ignition voltage will be lower, and the melting point of platinum is slightly less than that of titanium. If it is an ordinary spark plug, it may need to be replaced after about 30,000 kilometers of driving, and the number of kilometers traveled by platinum spark plugs may reach about 60,000 to 100,000 kilometers.

In the process of driving the vehicle, the driving habit of the owner is also related to the length of the life of the spark plug. It is recommended to let the vehicle drive smoothly and try not to apply the brakes too much, so as to effectively extend the life of the spark plug. It is easy to have carbon deposits during use, and if you do not clean it for a long time, it will lead to more and more carbon deposits, causing electrodes to leak or fail to catch fire, so it is necessary to remove carbon deposits regularly.

Anyone is concerned that everything can be taken into account, and the same is true for the purchase of spark plugs, can driving force and fuel economy be available at the same time? The world's three major well-known brands of spark plugs, NGK, BOSCH, and Denso. NGK itself has the advantages of raw materials, and it is very good at both driving force and fuel saving, and its sales volume is also one of the world's leading markets, so it is highly recommended for car buyers who want to take care of both fish and bear's paws.

In the domestic spark plugs, the Nanjing lightning spark plugs, which were quite famous earlier, also have many car owners who want to know how the lightning spark plugs in Nanjing are now, and whether they are suitable for purchase.

But it is a pity that today's Nanjing lightning spark plugs have long been bosch**, so we can learn about bosch spark plugs. The key is to cooperate with European and American brand cars, is the world's famous spark plug well-known brand, the key is to focus on the characteristics of stability, durable goods, for the importance of these aspects of the car friends is the best, but there is NGK spark plug that Qi clan like a driving force.

In fact, the interference of this spark plug to the engine is not more than 1%, relative to this, the main thing is the actual purchase of the situation needs to be cautious, the applicability of the spark plug is the most important, you can understand the following proposals.

1.Check how much is the spark plug external thread used in your own car How much is mm, at this stage the popular one in China is 14mm, so the general tightening of the spark plug specification, the torque is 25 30nm.

2.See how much heat is generated by the spark plugs of your own engine.

3.The key difference is that the Perkin spark plug has a longer service life, and the iridium spark plug has a faster ignition response.

Millions of car purchase subsidies.

For most car owners, they want to be able to take care of everything, and they naturally hope to save fuel and have good power in the purchase of spark plugs. The three major spark plugs in the world have a high reputation, namely NGK, Bosch, and Jiran.

1. NGKNGK spark plug is the best one in the industry produced in Japan, which has a high cost performance in terms of quality, and has also occupied a large market share in the world with Japanese cars.

2. Bosch. Xiaogao It is a spark plug produced in Germany, in the whole world 500, one of the products of auto parts manufacturers, mainly in the German series of models, but because Bosch this product is more, it is sold all over the country, and it seems that the quality of the spark plug in the domestic OEM is somewhat mixed.

3. Extreme combustion. This spark plug is one of the world's highest performance fuel saving from China, and it obviously has great advantages in terms of fuel saving and power improvement compared with other brands of spark plugs. It is also the only national brand that has the potential to break the monopoly of foreign brands, but from the current point of view, the popularity is not very high.

Summary. When the spark plug is used for too long, the ignition efficiency will be reduced if the design service life is exceeded, if the ignition efficiency of the spark plug is relatively poor, it will indeed have a certain degree of impact on fuel consumption, but the degree of impact is not too large, if the fuel consumption has a relatively large change, there may be other problems in addition to the spark plug.

When the spark plug is used for too long, the ignition efficiency will be reduced if the service life of the design is exceeded, if the ignition efficiency of the spark plug is relatively poor, it will indeed have a certain degree of impact on fuel consumption, but the degree of impact is not too large, if the oil consumption has a relatively large change, there may be other problems in addition to the spark plug.

So it's related.

There are other things that can make fuel consumption too high.

Lately, I feel like the car is coasting a little wrong.

You should check the tire pressure, low tire pressure is also one of the reasons for high fuel consumption.

It is also possible that the clutch plate is severely worn.

If there is a problem with the cylinder, it will be troublesome, and it will need to be overhauled.

If the tire pressure is normal, the car is bought and now it is 40,000 kilometers.

There is also a need to look at the oiler.

The clutch should be fine.

The wear and tear is also relatively serious, you can consider changing the tires, tire wear will cause you to reduce the distance you can glide.

What does an oiler mean.

You drive the car to the 4S shop, and the maintenance master will check and write it for you. The oiler is there to make you burn gasoline better.
