Niciodata , masina a fost inainte de cumparare in service pt a o da buna, fara probleme(e luata din familie)

Va salut, ce model din cele 2 recomanati pentru Solenza?

DENSO K20PR-U
NGK BKR6E
Mersi frumos.

Eu pentru dsn o sa cumpar NGK BKR6EZ.
De astea am cautat eu pe aici si se vorbea numai de bine.

Sunt diferente mari intre BKR6E si BKR6EZ?
Nu a folosit nimeni DENSO K20PR-U sau
NGK BKR6E ?

Luati ma de origine, cu 2 electrozi. Eu am avut BKR6EZ (au un fel de "V" in electrodu central). Motoru merge exact ca si cu cele cu 2 electrozi, doar ca cele originale-s la juma' de pret.

Am avut si originale cu un electrod si cu 3 electrozi,
O sa caut cu 2 electrozi sa vedem daca e o diferenta, pana acum nu am vazut diferenta, porneste cam la fel de cand o am.

Ideile importante:

-Generally the applications with low cylinder pressures (low compression ratio) running lean A/F (Air/Fuel) mixtures have large recommended gap (around .050"), and applications with high cylinder pressures (high compression, forced induction - turbo, supercharged, nitrous applications,...) require spark plug gap smaller than .032". The dense A/F mixture is much harder for spark to penetrate, and require much higher voltage (pressure). Higher fuel concentration has the same effect (lower A/F ratio).

-It is not uncommon to gain as much as 20 Hp just by replacing used spark plugs.

-For the best engine and spark plug performance, the size, style and shape of the spark plug gap should correspond with many factors. Some of them are:

1) Potential of the ignition system - Spark Voltage (sometimes explained as Voltage potential or electrical pressure) corresponds with the distance that spark can cross at given air pressure and enviroment (concentration of the A/F (Air/Fuel) mixture etc... between the spark plug gap (center electrode and ground electrode).

2) Pressure in the combustion chamber at time of spark discharge - Depends on compression and aspiration of the engine. High compression engines and engines with forced induction have higher combustion chamber pressures at time of spark discharge. Higher cylinder pressure requires higher voltage for the spark to occur.

3) Type and concentration of the fuel - for example fuels with high alcohol content requires lower A/F ratio and smaller spark plug gaps.

4) Engine ignition timing advance - the closer to the engine TDC (Top Dead Center) the spark occurs, the higher is the A/F mixture pressure it has to fire, and the harder for spark it is.

5) Engine load and intended use - when engine is under load, the pressures in the combustion chamber is higher as there is more air aspirated, making it harder for spark to occur. High RPM applications also shorten the ignition coil saturation (on time or DWEL) resulting in less available energy.

6) Type of Ignition system - magneto, CD (Capacitor Discharge), or Inductive. CD ignitions have very fast Voltage rise (short rise time) and therefore they also work very well with spark plugs that have high capacitance, such a spark plugs with multiple gaps and/or surface discharge spark plugs. On the other hand Inductive ignition systems generally provides longer spark duration...


-Too much spark plug gap can result in misfires and hard starting. Too little gap can result in a loss of power.
-In our experience a gap of between .030-.035 works well for most combinations
