The engine does not work without this part, but what can I do if it cannot be opened?

Compared to the parts that are often replaced in the maintenance of oil, machine filters, and air filters, the effect of the spark plug's working conditions on the engine's power and fuel consumption is very straightforward. A cylinder misfires, idling increases jitter, engine power drops, and fuel consumption rises.

Let's take a look at what spark plugs do first. It is a component of the gasoline engine ignition system that introduces high-voltage current into the cylinder to generate sparks to ignite combustible gas mixtures; in short, the car engine needs to burn fuel, and the spark that ignites the fuel is generated by the spark plug, so the spark plug The quality of the engine affects the working results.

The most important influencing factor is the gap between the spark plug electrodes. If the gap is too small, the spark is weak, and the leakage is easily caused by carbon deposition. If the gap is too large, the required breakdown voltage increases, the engine is not easy to start, and it is easy at high speed. A "misfire" occurred.

If the spark plug ages, the overall performance of the vehicle will be affected. However, since the spark plug is not a wearing part and is not a consumable product, it is naturally not an accessory that is often mentioned. Many people are unaware of how long the life of a spark plug is. As a part that is not easily dismantled and viewed, I don't know how to determine if the spark plug needs to be replaced.

Under normal circumstances, we can make a basic judgment on the condition of the spark plug in three situations.

The first is the maintenance manual. Each car engine, its power parameters, engine cylinder compression ratio, and engine operating temperature are not the same, and the brand of spark plug used is also different, the life expectancy will be very different! Therefore, each car manufacturer will have different replacement requirements. We can usually refer to the maintenance manual for replacement.

The second is concerned with mileage. In general, the spark plug replacement cycle is directly related to its material. The nickel alloy spark plug replacement cycle is 20,000 to 30,000 kilometers, the Ni-Nb alloy spark plug is 30,000 kilometers, the single platinum spark plug is 40,000 kilometers, and the double platinum spark plug is 6 Thousands of kilometers, gold spark plugs for 80,000 kilometers, platinum and rhodium alloy spark plug replacement cycle up to 100,000 kilometers.

Of course, these replacement cycles are only theoretical under normal circumstances. The specific replacement cycle depends on the use of the vehicle.

The third is to pay attention to the condition of the vehicle and driving experience. Each spark plug of the engine is particularly important. If one of the spark plugs is broken, or the overall performance of the spark plug is degraded, it will directly lead to a drop in our engine power. At this time, we can use some methods to drive it out.

If you feel that it is difficult to start the vehicle in a cool car state, sometimes it will not respond to fire several times, or there may be obvious frustration, idle jitter, and degraded engine acceleration performance. Most of them are spark plug aging. Caused by damage.

The second is to judge through a specific driving environment or method. For example, driving uphill or slamming on a straight road. If our spark plugs have performance problems, the power of the vehicles will drop, and there will obviously be a lack of power when we go uphill. In the past, the three gears could go uphill smoothly, and now there will be some reluctance to go uphill in the third gear! The need for an engine's power output is extremely high when it is rapidly accelerating. If the spark plug does not work well, it will easily cause the engine's power output to be unsteady and feel like a meal! This also needs to check spark plugs!

Finally, for owners who need to replace spark plugs, Cang Ge suggested that do not blindly pursue the alloy material of spark plugs, and even more simply that the more expensive the spark plugs, the better the combustion effect of the engine. The combustion effect of the engine is related to many factors, and the spark plug is only one of the aspects. However, using the higher quality alloy spark plug, the most direct effect is that the replacement period can be greatly extended, and the combustion effect does not play a role.
