ENERPULSE, an ignition products company, announced today that its prototype pulse plug (Pulstar), has demonstrated a 2.7% improvement in spark-ignition engine vehicle fuel efficiency over spark plugs in Environmental Protection Agency (EPA) tests.
Pulstar is the first capacitor-enhanced spark plug. The drop-in replacement for spark plugs uses the capacitor to store and then discharge the ignition’s electrical power in a powerful pulse.
What makes Pulstar different from spark plugs is its built-in capacitor, which stores the ignition’s electrical power and then discharges it in an intense plasma ball. Pulstar is capable of delivering up to 10,000 times the power of an average spark plug, which translates into greater fuel efficiency, increased torque and horsepower and reduced hydrocarbon emissions. In fact, spark plugs can be compared to the low-power output of a flashlight, while pulse plugs generate intense power like the brightness emitted from a camera’s flash bulb.—Daniel Parker, ENERPULSE CEO
Testing in the EPA’s FTP 75 test resulted in a 2.7% increase in fuel efficiency. Internal tests conducted by Enerpulse demonstrated a nearly 9% improvement in fuel efficiency. This test also showed a 7% improvement in torque and a 10.5% improvement in horsepower output over regular spark plugs.
ENERPULSE plans to conduct extensive additional testing in 50 different vehicle makes and models to measure fuel efficiency, torque and horsepower performance.
Altira, a Denver-based venture capital firm, provided the first round of financing in early 2004 to develop the Pulstar prototypes and fund the necessary EPA and independent testing of the new technology. ENERPULSE is now seeking to attract a second round of investment capital to finance the market launch of the product.
Enerpulse had marketed an earlier version of the technology in a 2-piece sparkplug it called DirectHits.
