Will using a non resistor spark plug increase or decrease engine power?
Using a non-resistance spark plug in a resistance plug system weakens the spark and therefore affects engine performance. The resistance of the plug and that of the electrode gap add up. Our coils and ignition amplifiers are designed for this absolute resistance.
Spark ignition is resistively sensitive. The voltage builds up in a ramp, regardless of how the spark is generated. A resistance spark plug delays the time in which the spark jumps.
This effectively delays ignition and reduces performance and efficiency. This change in time can be compensated for with less spark plug gap.
The gap is the “voltage regulator”. It is not intended to be the timing device. BUT! If you’re not a competitive tuner dancing for world records, you will never notice the change in performance, efficiency, or timing caused by problems.
CDI, magneto, B + powered ignition coils and computer controlled ignition systems work equally well with or without additional resistance in the high voltage ignition.
It is only important that radio interference occurs and that motorsport is really competitive. In any case, a voltage is applied, measured over an interruption.
If you need this extra power available to “ignite” the combustion chamber without resistance.
Using a non-resistance spark plug in a resistance plug system weakens the spark and therefore affects engine performance.
The resistance of the plug and that of the electrode gap add up. Our coils and ignition amplifiers are designed for this absolute resistance. Resistance determines the strength of the spark that manages to jump the gap.
If the total resistance is reduced, either by reducing the electrode gap or by using a spark plug with less resistance, a spark will jump across the gap before it reaches considerable strength.
This means a weak and early spark. If your spark is weak and incorrectly set for the respective variables, you will obviously lose engine efficiency and performance.
The use of a resistance spark plug and an ignition system for non-resistance spark plugs also has a negative effect on the output power.
If the resistance is insurmountable, the strongest spark that is possible on the system may not jump across the gap at all. This can also burn coils as their charge builds up to extremes they are not designed for. It is best to use the specified plug and gap for the motor.
