The replacement of spark plugs is actually part of daily maintenance, just like changing oil and three filters. Can you notice that after the maintenance, the maintenance master will help you check the spark plugs to see if you need to replace it. If one or two of the inspection needs to be replaced, then you should replace all the set. Today we will talk about why the spark plugs are 4.
Can the spark plugs be used after the replacement cycle?
There is a cycle of conventional maintenance accessories on the car. The replacement cycle of spark plugs is generally 20,000-100,000 kilometers (different materials cycles are different), but it is not necessary to use the official specified period of time. The surplus comes, so after the cycle, it will not cause fatal damage to the engine so quickly, but after the mileage, the wear of the electrode will be accelerated, the electrode gap becomes larger, the ignition is unstable, the voltage demand is higher, the performance of the light ones is the performance of the light. It is the symptoms such as accelerating weakness, ignition of fire, fire, and oil. In severe cases, the electrode fracture engine may also occur. Therefore, it is recommended that you replace it according to the prescribed cycle. In addition, there will be problems with other parts.
Can the spark plug only change one?
Generally, those who repair cars will be replaced all of you. In theory, even if a brand is the same model, the discharge gap between the old and new spark plugs is different, and the resistance value of the old and new spark plugs is different. Not all changes will occur. The energy of the ignition angle is different, resulting in unbalanced power of the four cylinders.
There is also a certain life span of spark plugs. The quality and life of the same batch of products should be very close. Since there are one or two problems, it shows that other spark plugs are also coming. So replace them together to prevent post -troubles.
The common electrode materials on the market are copper, nickel alloys, platinum, and gold (Platinum and Gold are generally called precious metals). Metal conductive performance increases from left to right (copper nickel alloy> Platinum> 铱 铱), so precious metal spark plugs are smaller in the load of the engine and are beneficial to reduce fuel consumption. In addition It also increases with the increase of performance.
There are other factors in addition to seasonal factors that cause spark plug accumulation: in addition to seasonal factors:
1. Long -term idling operation of the engine.
When the engine is running, the mixed gas is relatively strong and incomplete. At the same time, the engine cannot effectively use the exhaust inertia for exhaust, resulting in the increase in residual exhaust gas in the cylinder, and a large amount of spark plugs, resulting in too much spark plug accumulation.
2. Excessive wear between the piston and the cylinder wall.
When the piston and the cylinder are too abrasion, it will not only cause poor cylinder compression, but also cause the crankshaft box lubricating oil. In this case, it will not only reduce the heating value of the cylinder due to poor engine compression, but also cause the spark plug to not be self -cleaning. At the same time, the lubricant from the crankshaft box cannot participate in the combustion in full Carbon.
3. The valve oil seal is damaged.
When the valve oil seal of the engine is damaged, the lubricant can enter the cylinder. Due to the damage to the valve oil seal, the lubricating oil is not only a waste of lubricating oil, but it will also accelerate the accumulation of spark plugs due to poor lubricating oil volatility, incomplete combustion, and a large amount of glue in lubricating oil. When the spark plugs are severely accumulated in carbon and oil, they can usually be used after removal, but the effects and life span have decreased.
