Everyone are familiar about spark plugs. A brand called 'Pulstar' launched a new kind of spark plug called as pulse plug. Pulse plugs - a different innovation in spark plug technology and design acclaims to increase horsepower and fuel efficiency. The new pulse plug produces a stronger and wider spark when compared to the existing spark plugs. Generally the main work of the spark plugs is to ignite the charge (air and fuel) in gasoline engines. The more better and complete combustion of charge also drastically increases the horse power and efficiency. In this post lets see about the technology behind pulse plugs in comparison with existing the spark plugs.
Spark plugs work similar to a lightning bolt in clouds. To create a spark the power should have a very high voltage in order to travel across
the electrode and create a good spark.

Voltage at the spark plug can be
anywhere from 40,000 to 100,000 volts. This high voltage is usually produced by an induction coil. This induction coil is similar to a step-up transformer to produce a high voltage discharge.

The high voltage from the induction coil is supplied to the spark plug by the spark plug cable and a spark is created between the electrodes of the spark plug.
In pulstar spark plug, a capacitor space is included in the plug which boosts the voltage when compared to an ordinary conventional spark plug. This high voltage discharge produces a wider and better spark. But it is not 100% guaranteed that it improves HP and fuel efficiency. Normally a new spark plug performs better compared to the old one, so it is tough to decide which is a better one.

NGK iridium spark plugs produce a consistent and steady spark area which improves performance. It lasts longer than ordinary spark plugs. The Pulstar pulse plugs are usually larger in size and pricy too, plus they don't have fit properly in many vehicles. Not available in our country.

The only advantage of using a pulse plug is that it can produce a spark with larger area. Hence the combustion becomes complete even the charge (air & fuel mixture) is lean or rich.
I wish Bajaj could have used a single pulse plug instead of using 3- spark plugs in Pulsar 200NS.
