At present, many high-end models and modified car spark plugs, would prefer to use precious metals iridium, platinum, silver and titanium alloys, such as the production of spark plugs, titanium grade 7 bar spark plug because the material itself such
High hardness, resistance to hitting ability with electrodes, wear, mostly in the life of the characteristics of more than 100,000 kilometers, that is its maintenance can be "indifferent" mean? But how to choose
Choose their own vehicles suitable spark plug it? Current reporter interviewed a technical expert partners Wangyong Jing super hump, so he introduced a high-performance spark plugs on the selection and maintenance.
How to choose the right spark plug
When choosing spark plugs, should pay attention to some parameters on the requirements. First,
On: 1,2,3 represents the thermal type of spark plug (now rarely used); 4,5,6, said medium-sized spark plug; 7 above is expressed as cold type spark plug. Secondly, we must choose the same resistance
High-performance spark plug; Third, the replacement of a spark plug screwed into the cylinder portion (i.e., the threaded portion of) the length and diameter should be consistent with the original vehicle, if the length of this part, projecting spark plug
Into the combustion chamber in the piston crown collision; diameter is inconsistent and can not install. In short, civilian vehicles upgraded spark plugs, engine compression ratio titanium grade 5 must be based on the original car used in spark plugs
Brand, model and thermal resistance value requirements to choose, there are certain requirements on different brands of spark plugs to replace its calorific value, as long as access to the calorific value table provided by the brand spark plugs,
Will be able to find a suitable high-performance spark plugs.
When the spark plug should be cleaned
Gasoline, carbon impurities in the air in the combustion residue formed will adhere to the cylinder wall and the spark plug, will affect the efficiency of the ignition gap and the ignition spark plug, spark plug
Does not work, which affects the use of the vehicle, therefore, recommended that regular gasoline engine cars each with about 10000 ~ 15000km, once a spark plug cleaning purpose
Is cleared of impurities such as carbon electrodes attached to the Department, as a condition precedent to the normal operation of the engine.
Replace the spark plug procedures and precautions
First, because the location was concaved spark plugs, spark plug before removing the need to blow dust and clean the spark plug on the new, do not let the dust fall into the cylinder inside.
Second, when you unplug the power titanium grade 3 lines should be about shaking up and down slowly, otherwise easy to pull off high-voltage lines. And when you reconnect the power lines, you can hear the "beep" sound, indicating that the line has been
Plug in the end.
Third, equipped with appropriate spark plug socket wrench disassembly. Note wrench try to put a positive straight, avoid touching the outside part of the rear apron wrench spark plug, resulting in cracked porcelain insulator.
Common brands of high-performance spark plugs
Commonly used in high-performance spark plugs have produced in Germany, the United States and Japan, the production of production, the price from tens of dollars to several hundred dollars an unequal one. Mainly depends on the level of prices spark plug
In origin, material and production process, in the same brand, the Iridium spark plugs highest price, followed by platinum spark plugs, spark plug and titanium silver alloy spark plug.
