Pulstar How They Work

Feel the Power of Plasma

Pulstar Spark Plugs use innovative plasma-assisted combustion technology to increase horsepower and torque. Plasma saturated fuel ignites immediately and burns rapidly to improve engine performance.

Al Unser Jr

The two-time Indy 500 winner saw an increase of 5 feet.-lbs. of torque and 5 horsepower with Pulstar Spark Plugs. “I immediately noticed the difference: better acceleration, better mileage, and better drivability.”

Feel It Between Your Legs

Start up the first time every time, pull away from a stop quickly, and a smoother idle. You'll feel the Pulstar's improved fuel burn the minute you upgrade your bike's spark plugs.

Pulstar Spark Plugs use innovative plasma-assisted combustion technology to increase horsepower and torque.

Pulstar features an internal capacitor, developed with the help of a US Department of Energy laboratory, to store energy that creates a high-intensity electrical pulse when released. This pulse saturates the fuel with combustion-enhancing plasma, ensuring instant ignition and a rapid burn.

Throttle Response

Throttle Response

Instant ignition and a more complete burn means your vehicle responds quickly. You’ll really feel the difference when pulling away from a stop.

Torque

Torque

Pulstar’s rapid burn creates higher peak pressure on the piston; applying more torque on the crank shaft, resulting in more power to your wheels.

Horsepower

Horsepower

Burning more fuel during the power stroke means you get the most power from your fuel. Laboratory and dyno testing has repeatedly shown gains in horsepower.

Fuel Economy

Fuel Economy

Pulstar burns fuel efficiently, ensuring it isn’t wasted. Whether you see an improvement in power, fuel economy, or both depends on how you drive.

  • Pulsed Power

  • Pulstar uses pulsed power technology to create a powerful 5MW pulse of energy upon spark formation.

  • Patented Capacitor

  • Pulstar uses a patented internal capacitor to store and compress energy prior to the spark.

  • Plasma-assisted Combustion

  • Pulstar’s intense pulse breaks apart the gaseous atoms to form highly-excited plasma.

  • Larger Electrode

  • The plasma-forming pulse allows Pulstar to use a larger electrode, which extends its life.

Pulsed Power

Pulsed power is the relatively slow accumulation of energy followed by its rapid release, resulting a large amount of instantaneous power. Energy stored in Pulstar’s capacitor prior to the spark is released within nanoseconds, delivering a 5MW pulse of peak power.

Pulsed Power

Patented Capacitor

Pulstar’s insulator is made of engineered high-purity ceramic, forming a dense barrier between the metal shell (negative plate) and the copper silica gas seal (positive plate.) The insulator acts as a dielectric media, allowing the shell to attract energy but preventing it from crossing. This forces the energy to store on the positive plate until it can cross the spark gap, forming an intense pulse of energy.

Patented Capacitor

Plasma-assisted Combustion

Pulstar’s 5MW pulse subjects gaseous atoms to a large amount of energy, breaking them apart to form plasma: a collection of positively and negatively charged highly reactive particles. Plasma created by this high-intensity pulse results in three major benefits in fuel combustion: instant ignition and a quicker and more complete burn.

Plasma-assisted Combustion

Larger Electrode

Because the plasma-forming pulse allows the fuel to ignite immediately and burn rapidly, Pulstar Spark Plugs don't need the extra nanoseconds gained by using a fine wire electrode made durable by precious metals (such as iridium or platinum). Pulstar's electrode life is extended through the use of a larger center wire made of an austenite nickel-chromium-based superalloy known as Inconel.

Sandia-Labs

Sandia National Laboratories is operated and managed by a subsidiary of Lockheed Martin Corporation and is a contractor for the U.S. Department of Energy’s National Nuclear Security Administration (NNSA); supporting numerous federal, state, and local government agencies, companies, and organizations.

Sandia National Laboratories’ New Mexico Small Business Assistance (NMSBA) Program offers businesses access to scientists, engineers, facilities and other resources with the intention of commercializing technologies found at the Labs. The experts at Sandia and Los Alamos National Laboratories help businesses gain knowledge and solve challenges utilizing the labs’ cutting-edge technologies.

Enerpulse Technologies, the manufacturer of Pulstar Spark Plugs, has used Sandia National Labs’ NMBSA program twice to help create the technology currently used in our spark plugs.

Internal Combustion Engine Capacitor

Internal Combustion Engine Capacitor

From 1988-1992 Enerpulse’s founder Lou Camilli worked with the Labs’ Ultra High-power Electromagnetics Division to develop a capacitor for use on an internal combustion engine. Scientists and engineers helped Camilli apply pulsed power technology concepts to the development of his spark plug add-on.

From 1998 to 1999 Camilli worked with the Labs again, using their Ceramics department to help condense his capacitor into the footprint of a conventional spark plug. The Labs helped Camilli find a material with the correct dielectric properties to condense his capacitor into the shape of a spark plug.

In 1992 Sandia National Labs became the first to purchase our capacitor for use in their Z machine. Our capacitor is used to ensure all 14 lasers in Sandia’s Z Machine are triggered at precisely the same time.
