That is spark plug,
it is consistent with the spark plug model of the original car.
The spark plug type usually appears on the ceramic body and consists of a series of letters and numbers representing the appearance parameters and engine characteristics of the spark plug.
Different models of spark plugs have many differences in parameters,
such as electrode material and design,
thread diameter,
thread length,
caloric value, clearance,
resistance value,
can not simply through the appearance to judge whether suitable,
spark plug matching engine characteristic parameters are also very important.
Different m A suitable spark plug needs to go through the manufacturer’s internal and automobile manufacturer’s strict testing and verification,
if the replacement of the spark plug model and the original requirements do not match,
it is very easy to cause a series of car failures,
such as flameout,
shaking,
acceleration and car,
will also affect the performance of the engine.
In addition to the spark plug type,
the spark plug electrode material can also be used as a reference,
which determines the ignition performance and durability of the spark plug.
The common spark plug electrode material is nickel alloy, upward upgrade can be single platinum,
single iridium gold,
double platinum,
iridium platinum and other precious metal spark plug.
Platinum,
iridium gold based precious metal spark plug ignition performance is excellent,
durability of single precious metal (single platinum, single iridium) spark plug and nickel alloy spark plug replacement cycle is similar,
recommended every 20,000 kilometers or so regular spot inspection and timely replacement,
ouble precious metal (double platinum, iridium platinum) spark plug is a long life spark plug,
more durable,
specific replacement cycle to the operation of automobile manufacturers The manual shall prevail.
In addition,
oil,
driving habits, road conditions,
climate and other factors will also affect the life of the spark plug,
it is recommended to include the spark plug into the range of daily maintenance,
can effectively extend the replacement cycle.
