INTRODUCTION

Pulstar pulse plugs by Enerpulse look and fit like traditional spark plugs, but are exponentially more powerful. Pulstars discharge with 10 times the energy of a spark plug! This high power pulse discharge ignites the compressed air/fuel mixture in the cylinder more precisely and completely, producing on average 6% better fuel economy and torque.

With the assistance of Sandia National Laboratories in Albuquerque, Enerpulse developed Pulstar™ to increase the peak power of the spark by 10 times and ignite gasoline in the engine's cylinder more completely, with less cycle-to-cycle variation. The result is more engine torque, more horsepower and better fuel economy.
The high power of the Pulstar™ will not damage an engine because the high power event lasts only for 2 microseconds (billionths of a second). This very brief moment is enough to ignite the fuel in the cylinder, but too brief to overheat the combustion chamber or metal engine components. So it will neither harm your engine nor void your manufacturer's warranty.
Pulstar™ looks like a spark plug because it was designed to fit into the same hole in your engine. But, internally, Pulstar™ is very different, incorporating a pulse circuit no other plug has. This is why we call Pulstar™ a "pulse plug" and not a spark plug


WHAT MAKES A PULSE PLUG?


Terminal: This is the primary connection point to the rest of the ignition system. It is shaped so the wire usually just snaps onto the top of the plug.

Insulator:Made from an aluminum oxide ceramic that is able to withstand very high temperatures and protect against the high-voltages that the ignition system requires from ‘leaking out’.

Resistor: This is what keeps EMI and RFI from getting into the advanced computer systems of today’s automobiles.

Pulse Circuit:This is what separates a pulse plug from a normal plug. Here, the energy is stored to be released into the gap once breakdown voltage is achieved by the ignition system. A typical plug will have only the resistor then a conductor that continues to the center electrode.


Plated Shell:This provides the hex to torque down the plug, the threads to hold the plug in the engine, the sealing surface to keep combustion gasses in the engine, the mounting point for the ground strap and the connection to ground for the plug.

Gas Seal: This part of the plug keeps the combustion gasses from just pressing out the center electrode on the plug and causing a leak. Center Electrode: The center electrodes on plugs are made from many different materials from copper to inconel to iridium. This is the first half of the plug that actually creates the gap for the spark.

Ground Strap: The ground strap is the second part of the gap and comes in a multitude of shapes and materials
