Today I got my hands on a 3kW generator. I made a custom fuel measuring glass with marks for every 50 grams of fuel. Then I connected this new fuel tank to the generator. I loaded the generator with a 600w load and measured what time does it take to consume 250ml of fuel. I did this several times to get an average result. Then I replaced the original spark plug with the pulstar pulse plug and made these tests again. Each test was about 15 minutes long and I three tests for each spark plug. Then I calculated the average seconds and the difference percentage. Pulstar spark plug could tahe the load about 2% longer than the original spark plug. This might be due to the fact that the original spark plug is a cheap one and has smaller spark gap spacing thus smaller spark, that may not ignite the gas mixture on some pulses. After all, 2% is about 15 seconds of time. I will make some more tests tomorrow with longer cycles and bigger load on the generator. Also I will try a high quality iridium spark plug from a water jet engine. Then we will see if those pulstar spark plugs really do what they claim, or are they just a scam.







On the last picture the right spark plug is the original generator spark plug. The other is the pulstar plug.
