SPARK PLUG REPLACEMENT

The spark plug almost invisibly carries out its service under the hood of the engine. It only draws attention to itself when it is not working – in which case it may already be too late. If you don’t know what to do with an old or badly broken down car, consider taking advantage of scrap cars scarborough.

“start-stop-stop” driving,
Driving short distances.

If your engine is running rough, if you experience frequent ignition interruptions or if you notice that your car’s engine output has dropped, don’t wait until your next service check-up to replace the spark plugs. After all, replacing spark plugs in a timely manner spares the neutralizer, the engine, the environment, your wallet and reduces gasoline consumption.

The replacement interval for a standard spark plug is 15,000 km.

A few important things to know about spark plugs

Spark plugs must be able to withstand high chemical, thermal and mechanical loads. Only a quality product guarantees reliability and fuel economy during vehicle operation. The insulator is usually grayish-white in color.

But sometimes there are failures or malfunctions, which manifest themselves as follows:

Deposits due to mechanical wear of the engine (oil consumption) contribute to the occurrence of glow ignition, which causes engine damage.
Remedy: Check the spark plugs more frequently or replace them
Damage to the insulator due to improper handling (torque, impact, transportation) or thermal shock
Melting caused by abnormal combustion (glow ignition, detonation combustion).
Corrective action: check mixture or ignition conditions
Coating with soot as a result of extremely frequent short-distance travel.
Troubleshooting: clean or blow dry the spark plugs with compressed air, and then let them clean completely while driving under increased load, because spark plugs are best cleaned by the engine

It is not uncommon to use fuel with metal additives to increase the octane number. The antiknock additives that are used cause a buildup of Fe (iron) on the inside of the spark plug insulator. The insulator takes on a reddish-brick color. Ignition skips and spark plug failure in this case are the result of poor fuel quality.

A little bit about platinum and iridium plugs

High-performance spark plugs with a PLATINE center electrode
A large number of spark plug types with a platinum center electrode have been developed to meet the requirements of high performance engines and high-performance driving conditions. These spark plugs have a platinum electrode with a diameter of 0.7 mm.

The platinum center electrode spark plug provides:

A thinner platinum center electrode that requires less voltage and generates a stronger spark
easier starting and faster acceleration
tapered side electrode increases combustion efficiency

New spark plug technology with IRIDIUM center electrode

The secret of the new spark plug lies in the laser-welded iridium electrode. Thanks to its “minimal” diameter of only 0.6 mm, this spark plug concentrates the ignition voltage as it were. This improves combustion in any engine range, so that the engine runs smoothly and accelerates faster.

The high-tech iridium metal maintains precise electrode gap over a long service life. This prevents ignition interruptions.

Advantages of spark plugs with iridium center electrode:

Iridium spark plugs’ optimal ignition qualities prevent fouling, even under extreme conditions for a spark plug
spark discharges in the groove of the insulator prevent the formation of soot around the center electrode, which prevents leakage and ignition skips
Highest ignition reliability, homogeneous combustion, optimal engine output
Maximum injectivity and excellent accelerator pedal response, which reduces the fuel consumption, is the result of the most modern technologies, used in production of these spark plugs
Due to the thin center electrode and the “beveled” side electrode the damping effect at ignition of the mixture is minimized, which in turn ensures the fastest and most effective spread of the flame front.
Iridium spark plugs last at least twice as long as any conventional spark plug. This eliminates the need for frequent spark plug replacement, which in turn reduces costs.
