A blistered white insulator or melted electrode indicates over-advanced ignition timing or a malfunctioning cooling system. If correction does not prove effective, try a colder grade plug. . BURNT OIL White deposits have accumulated from excessive amounts of oil in the combustion chamber or through...
But wet fouling can also be caused by dirt or moisture on the outside of the plug that provides a conductive path to ground, or by an internal crack in the ceramic insulator that shorts the plug to ground. Oil fouled spark plug Heavy black deposits with an oily appearance. These are the...
Heat range refers to the operating temperature range of the spark plug. A spark plug must run hot enough to burn off fouling deposits but not so hot that it causes preignition or detonation. Most spark plugs use a copper core and electrode design that gives them a broad heat range and ma...
where it can jump the gap and, from there, be conducted into the engine block and grounded. The plug also has to withstand the extreme heat and pressure inside the cylinder, and it must be designed so that deposits from fuel additives do not build up on the plug. ...
Matters of thread diameter and length resolved, you can still get into trouble with a spark plug property called "heat range." All conventional plugs, whatever the application, have to stay hot enough to burn away deposits (oil, carbon, etc.) that otherwise would short-circuit the spark, an...
a●4万公里时清理积碳,调整三个负极点到正极点的间隙,以延长火花塞的使用寿命。 * When 40,000 kilometers cleans up the carbon deposition, adjusts three cathodes to a positive electrode gap, lengthens the igniter plug the service life.[translate]...
chromate treatment liquid. Then, the dissolved base metal reacts with a solution containing chromate ions. With this, a complex (in the form of polymer) is formed by trivalent chromium through a bridge of hydroxyl group or oxygen. This complex precipitates or deposits in the form of gel on ...
On an average plug, a narrow core typically shortens life span of plug but with the intense durability of iridium there is no sacrifice in any longevity. With a high melting point of 2454 degrees C, opposed to the 1769 degrees C of white gold, the electrode can tolerate the high l...
the white ribbon is a tether that is shorter than the black data cable connecting the connector to the front face. When a technician is lifting off thenot light weightfront face, if they pull directly out, the tether tightens and pulls the plug from the mainboard, all without having to ...
It was found that the Ni electrodeposited from Watts electrolyte could manifest the highest microleveling power and effectively decrease the roughness of electrospark deposits by up to four times. However, the oxidation of the nickel during the friction tests led to ambiguous behavior by the tested...
