“Pulse Plug” Demonstrates 2.7% Improvement in Fuel Efficiency

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.

I wonder how a million watt plasma ball will interact with my Joe Cell.
"The use of high performance spark plugs, distributor and coil may significantly improve the
performance of a Joe Cell powered engine."
There's nothing Quite as rewarding as running an internal cumbustion engine with no fuel!
Can't wait to try 'em.

Unlike you folks, I purchased 6 for my torrent last night, so I will be able to determine first-hand, not on a blog that many feel they can say anything about, with or without experience.
I've always been an "early adopter", perhaps that's why I am a steam engineer, not a blogger.

Experience is the teacher, the only Reliable teacher

New Pulstars replacing Bosch 4-prong fusion (Platinum & iridium) plugs with 25K miles on them in 1995 Buick Ultra, 3.8 V6 supercharged. 225 HP, 275 Torgue. Burns 91 octane premium.

At first I felt some hesitation or miss after multiple hard accelerations. Enerpulse said to re-set to .035 due to the supercharged induction engine. I did, and problem solved. I maintain the car impeccably, with recent top end gasket replacement and timing chain. Running Amsoil's new 0W-30 (zero W-30).

Now, idle is silk smooth without the occasional hiccup. Starting, cold or hot is quicker, almost instant-on. Noticed smoother stronger acceleration under light throttle in town. Full throttle feels stronger with no computer-adjusted backing off. Holds 70 MPH speed in cruise mode in overdrive on certain hills where it used to decrease speed and shift out of overdrive lock. I will check mileage for 10K before coming to any conclusions on economy. Currently, I get 17 city and 26 hwy. A 6,600 mile summer trip averaged 26.3.

So far, Pulstars have made a more noticeable difference than any single thing I have tried over the last 40 yrs. (some things have helped slightly) The Bosch fusions made no discernible difference over standard ones, but these plugs made a significant noticeable difference.

I am David Wofsey the inventor of the Sonic Spark Plug US Patent No. 5,610,470. At present, I have no experiance with the Pulse Star Spark Plugs. However, the claims made are extravagent. Unfortuneately, the technology, Physics, and Chemistry are probably understood by very few people. A concentrated initial spark is only a partial solution to increased fuel economy. I have been dealing with the spark plug market for over 10 years. There is much variability in the performance increase that one can obtain to a change in the technology of spark plugs. Yes, the spark plug is the important component in combustion efficiency. The spark plug companies make attempts to improve their products. Examples: multiple grounds, Platinum, Iridium, and changes made by independent inventors. They all claim improvements. However, specific claims are difficult to verify. Sonic Spark, Llc takes the path that the automotive engineers have optimized the spark plug spaecifications for their vehicles which is programed into the computor settings. With this direction, Sonic Spark, generally selects the spark plug make and number to match the specific vehicle specifications. Sonic Spark's Utra Sound modification is the only change made to the general OEM specified spark plug.
I must advise any one, or company that wishes to enter the spark plug market. It is tough. The Automotive Companies, and spark Plug Companies own their market. I wish PulsStar Good Luck.
Respectfully; David Wofsey, Inventor, Chief Agent

It would be interesting to add the Sonic plug to the dyno comparo by Sparkplugs.com.

See: http://www.sparkplugs.com/sparkplug411.asp?kw=SRT%2D4+Dyno+Results&mfid=0&KID=3095

Also some independent economy testing using stock, Pulstar and Sonic would really put things into perspective. It will take some time before I can see whether there is a difference on my car.

At $6.95 Sonic is certainly competitive compared to $25 Pulstars. Would be nice to know whether Pulstars are worth the extra money. Better stronger running result was like getting a great tuneup plus enhanced performance for only $150. So, $30 would be even a better deal for an equivalent result.

I am a SMOG check technician with my own dynamometer and Smog check engine emissions sampling computer. I received the pulse spark plugs not gapped properly. Two of them had a very wide gap and two had a very short gap. Be aware of u knowing basic mechanical knowledge. I ran a smog test with Brand new NGK Iridium spark plugs on a 2000 Toyota Corolla 1.8 I believe Iridium spark plugs last very long maybe 70000 miles. The test results with Iridium spark plugs came out good and a passing smog test. I replaced the new Iridium plugs with the newly arrived pulse spark plugs and corrected gap. I reset the car’s computer with a scanner and drove a couple of miles to allow the computer monitors to complete. The computer monitors completed and ran smog test. The smog test showed lower emission levels. Specially carbon monoxide. Example: Iridium spark at 15 mph .30 CO, pulse spark at 15 mph .02 CO.
I plugged in all the emission numbers into an equation that tells if your engine is or is not burning fuel at stoichiometric (1 X 14.71) Results were that my car with brand new iridium plugs did well at stoich, but with pulse plugs the result were almost perfect. .999 X 14.69.
The engine runs same at idle, but it runs smooth at low and high moving speeds. The pick up speed seems to be better. I do not notice any gas improvement.
I noticed one flaw. My car’s engine makes rattling noises with 87 gas, but noises went away with higher octane gas. My car did not care the type of gasoline I filled it up with when I had stock spark plugs.

Maybe if your car has mechanical problems and your car runs rich, this pulse spark plug would be a good band aid to correct and try to burn all the excess fuel.

Stills testing so far it seems to be a good product.

"Pulse plugs incorporate a pulse circuit, which stores incoming electrical energy from the ignition system and releases the stored energy in a powerful pulse of power. Instead of 50 watts of peak power typical of all spark plugs, pulse plugs deliver up to 1 million watts of peak power."

Use your brains people. Your car delivers 50 watts of juice to your plug. Unless your plugs have a another power source that is the most that will come out of them. If these things really worked you could use one to run your house on a AA battery.

The plugs work great out of the box. The pulse circuit on the set i bought burned out at 8000 miles. Once they get this number beyond 50000 they'll have the product of the year. I'll buy them again as soon as that happens.

daryl

what worries me about all these "claims" is the lack of statistical data! Where is the published study with a proper abstract, raw data, and results? what are the P-values of those results? what method of data collection and data analysis was used? how many different cars and in what climate conditions? were they all on the same dyno? the same tires and tire pressure and same quality fuel? This "2.7% increase" looks very suspect to me. Many people who have had their cars on a dyno will fluctuate as much as 5% up and down without much reason at all. This leads me to believe that the statistical significance of these gains is null. The subjective 'gains' people are experiencing just have too many unfactorable variables. It's an error of logic to assume a before and after test can be made a generalized truth. Just to calculate gas mileage alone you would have to consider weight, road surface, wind resistance, average speed, driving style, tire pressure, traffic, fuel quality, and altitude to name a few...and that's just for one car. Imagine this from a medical standpoint for a minute, would you trust this thing inside your body if the research isn't there to back it up? Don't believe in anything just because its in print! Also some coursework in Statistical Analysis and Research Methods, would be beneficial to all. Just my two cents.

I'm noticing a miss every now and then that I didn't have before in my 96 Riviera. I haven't had it checked out yet. Any ideas?

Gus Hernandez has a good point. By the formula P=IE or watts = amperage x voltage...Something has to give. If wattage increases then you need to give up voltage for current or visa versa... [which may explain the smaller gap] or current. Even capacitors [unless their flux, ha ha ]follow basic electrical laws. Unless I'm missing something here. To get more wattage one needs to increase current draw or increase voltage supply.

Bear Paws

My mistake. I guess it was Gus who I was referring to.

for hho, you seeem to know something about electrical theory, but i guess you missed the part that says these sparkplugs use a capacitor.

7ft24

Gus, the comparison on watts is true for a continuous discharge... a standard spark discharge on an engine dissipates the 50 watts continuously during the life of the spark (for example 100ms or so) take all that power, and make it all discharge at once only lasting 1ms...
now you have 5000 watts...
make it .01ms and you have 500000 watts...
that's the benefit of the capacitor (or a capacitor in any circuit with a discharge, either a spark or a photo flash tube etc)... just think of taking the total power you use in your house in one day, and make something that uses that much power in a second... Big difference!
With a photo flash, it's the same... hook up the voltage to the flash tube (about 450 volts) without a capacitor, and trigger the flash tube, you get a very weak pale blue discharge in the tube that may last for several seconds... pretty useless.
add a capacitor to the same voltage, and trigger it, and all that voltage dumps in over about 500ns or so... and you get a VERY intense, blue white flash. same principle.
TOTAL energy is the same (watts), but it is just dumped over a MUCH shorter time than without the capacitor.

I agree with daryl, they sound good, but we need the "100% satisfactory guarantee" for at least, and I stress at least 50,000 miles. Considering their price. And I really do hope they are good because I would like to try them myself.
