Some Cases A Brief Spark Plug

The importance of performance spark plug ignition: spark plug ignition engine performance directly affects the performance of play, if the spark plug ignition performance is not good, not only will there not easy to start, sluggish traffic, oil and gas incomplete combustion, fuel consumption is high, seriously affecting engine life, and generate a lot of gas, pollute the environment.

How to check spark plug used to judge the situation: Remove the spark plug to check the state can be judged according to their burned out spark plug and the engine is matched to the work of the state is normal. Good: spark plug, clean the surface of the electrode color is brown, yellow or yellow-white. Coking : Spark plug surface black, with coke or oil, indicating a problem. Overheated: spark plug surface ablation spot, the color is gray, indicating a problem.

What is a resistor type spark plug: resistance type spark plug is in the spark plug with a 5 euro within the ceramic resistor, spark plug can reduce the electrical interference on the car, to avoid interference on the radio, you can also protect the EFI car PC board damage from interference.

There are seven major contraindications spark plug, the following are brief.

Spark plug ignition system of the engine failure is one more component, the spark plug selection, use and maintenance of many aspects if negligence or misconduct, will affect its normal role to play. Spark Plug Maintenance, seven avoid:

Avoid long-term coke dirty spark plug. Spark plug in use, the electrodes and insulator skirt will have a normal coke production, coke long-term if they are not clean, will be cumulative, leading to leakage or electrode can not flash over. It should be on a regular basis (typically 3000-5000 km) remove coke, such as spark plug do not work when cleaning.

Spark Plug avoid arbitrary scale removal. Some people spray on silver or other engine maintenance, pay no attention to the appearance of clean spark plug, spark plug caused by surface dirt and leakage. Clean appearance when not map easy and fast to use sandpaper, metal strips, cleaning, and the spark plug should be immersed in gasoline, with the brush to be cleared to ensure the appearance of ceramic spark plug without damage.

Spark Plug avoid burning. In reality, there are often ways to use fire to clear the spark plug electrodes and the skirt of coke and oil, this seemingly effective way, in fact, very harmful. Because of fire, the temperature difficult to control. It is easy to burn insulation skirt split, resulting in spark plug leakage and fire resulting from the small cracks are often difficult to find, great for troubleshooting problems. Coke and oil on the spark plug the correct approach first used special equipment for cleaning, there will be a very good effect; second solution to clean, the spark plug into ethanol or gasoline soaked some time, when the coke and then use the hair to soften net-dry brush.

Avoid hot and cold, regardless of spark plug. In addition to spark plug of different shape and size vary, but also into cold type, medium, hot type of three. Generally high compression ratio, high-speed engine is appropriate to cold type spark plug; and low compression ratio at low speeds, the engine is appropriate to heat and spark plug in between there are medium-sized spark plug. In addition, the new engine or overhaul the engine and the old engine's spark plug selection may vary according to actual situation. For example, the newer the engine, the selection should tend to heat and spark plug; use of time principals old engine because of poor performance, spark plug prone to excessive coke formation and fouling by oil, used cold spark plug type of moving towards a medium to improve the spark plug Anti-oil capacity.

Spark Plug avoid misdiagnosis dislocation. Replace the spark plug or suspected malfunction need to check, it should be in the car after running a parking stall remove the spark plug electrode to observe the color feature, may have the following situations: First, the central electrode was red-brown, next to the electrode and 4 Zhou Chengqing gray, for the selection of a suitable spark plug; Second, there is ablation electrodes or pillow melting phenomenon was burning insulation skirt and white state, indicating selection of spark plug overheating; third electrodes and insulator skirt with black stripes shows that spark plug have been leaks. Spark plug selection of inappropriate or leakage should be re-select the appropriate spark plug.

Avoid installation of spark plug too tight. Spark plug installation must meet the required torque. Using special tools (ie spark plug socket) installed, generally not more than, if excessive force, excessive or spanner to install, then the spark plug porcelain often damage the core or to screw sliding buckle, the expansion tank rupture caused by spark plug scrapped; but should not be installed too loose, or cause the engine not working properly.
