Hydrogen Boost Passes Colorado Rapid Screen

Emissions Test

 

   In last month’s issue of our newsletter we reported on John Vine’s Test results on his Oldsmobile Silhouette minivan, seeing an average of over 30% increase in mileage.  This was consistent with the controlled test we did after installation using the Scangauge.  In John’s report he mentioned the Colorado alternative emissions test called Rapid Screen.

         

          John directed me to the web site that explains the Rapid Screen emissions test  http://www.aircarecolorado.com/rapidscreen/about.html .  Here is some information from that site.

 

An alternative to standard emissions testing, RapidScreen gives you the opportunity to have your vehicle’s emissions screened as you drive, rather than having to visit an emissions testing facility. If you record two clean RapidScreen readings within a ten-month window in the year prior to your registration renewal, you’ll receive a notification in the mail on your vehicle’s registration renewal card. If you choose to accept RapidScreen’s clean readings, simply pay your emissions fee along with your registration renewal fee, and you’re good to go. If you wish not to participate, you’ll need to receive a standard emissions test at your local testing facility—in which case your emissions fee would be due at the time of that test.

 

To ensure accurate and uncontaminated readings, the emissions limits for RapidScreen are stricter than those of a standard tailpipe emissions test. Therefore, it’s possible to fail a RapidScreen test, but still be able to pass emissions at an Air Care Colorado testing facility. If your vehicle fails to meet RapidScreen’s strict qualifications, the need for a standard emissions test will be indicated on your registration renewal card.

 

How It Works

  View Illustration

RapidScreen testing vans set up at highway on-ramps and other locations where vehicles are accelerating or driving uphill at a moderate speed, because these conditions generate the most representative sample of a vehicle’s exhaust emissions.

As a vehicle passes by, the roadside testing equipment is able to analyze the vehicle’s exhaust in less than a second. Here’s how RapidScreen works:

1) The vehicle first passes through speed and acceleration detectors, while an image of the license plate is recorded for identification.

2) The vehicle then passes through the infrared and ultraviolet beams of the emissions analyzer. A laser light source directs the beams across the road, where they are bounced off mirrors and directed back to a detector module. As the light beams are broken by the vehicle’s exhaust plume, the detector module measures the levels of carbon monoxide, carbon dioxide, hydrocarbons and oxides of nitrogen in the plume.

To ensure accurate, uncontaminated readings, RapidScreen testing vans do not operate during rain, snow, high winds or other adverse weather conditions. RapidScreen also holds to stricter emissions limits than those of a standard tailpipe emissions test.

 

Fran’s comments:  Notice the statement in the fourth paragraph above in bold maroon print: the emissions limits for RapidScreen are stricter than those of a standard tailpipe emissions test.  Since John’s Hydrogen Boost equipped vehicle passed this test, we are pleased to confirm that this is consistent with all we have said about emissions improvements with the complete Hydrogen Boost system.  Details are at http://www.hydrogen-boost.com/August%202006.html and

Follow-up from George:

Hi Fran!

     I just wanted to drop you a short note to say that the hydrogen boost system you installed for me is netting me much higher tank averages in the cold weather than I was getting last year.  (From 29-31 to 35-37 mpg's).  I am very happy with the system.  Of course, I can't finish the letter without a question, and it's not a big deal.  I was just curious about the water consumption of the hydrogen generator.  You installed my system back on October 21st, I believe.  I've driven more than three thousand miles since and I'm still on my first gallon of distilled water.  I have less than 1/4 of a gallon left.  I would have thought that I would have used more than that by now.  Any thoughts?  It's still pulling between 15 and 20 amps when fully warmed.   I just got back from a road trip to Quakertown, PA, and I averaged about 43 mpg's both ways.  I think it would have been higher without the high winds that day.  OK, that's all for now. 

Sincerely,

George Sills

Hartford, CT.

 

Fran’s response:

You are making an average of 1.5 liters gas per minute.  There are 1860 liters of gas in one liter of water.  That would be 1240 minutes driving per liter of water.  You have used 3 liters of water or 3720 minutes or 62 hours of driving.  So if you have driven less than 3100 miles since October, your water usage is about right.

Thanks for the update.  Your average mileage compared to last winter confirms a 20% increase as is typical with our testing.  Thanks for additional independent testing.

Keep up the good work helping the planet,

Fran
