Dear Mr. Gimple

Since our discussion the other day, I thought I would bring you up to date on my equipment which utilizes Platinum Vapor Injection (PVI).

You may recall from my previous correspondence that the PVI was installed 7/20/86 on my Kenworth 18-wheeler at 167,555 miles. I now have 566,250 miles, giving me 398,695 miles with your PVI unit installed on the 400-HP Caterpillar 3406 diesel engine. Shortly after installation of your unit, I noticed reductions in smell, noise, and vibration. Additionally, the oil samples taken at 8/20/86, 12/30/86, and 5/12/87 showed contaminant reductions for soot, oxides, nitrates, and sulfur to all, be at the zero or negligible levels. As a result, I was able to extend my oil change interval from 15,000 to 20,000 miles.

At 266,210 miles, the 15 cylinder broke the compression ring, and the engine had to be overhauled. When the head was removed, there was NO hard carbon buildup on the valves, pistons, or rings. The rings, which you now have, have not been cleaned. They were only wiped with solvent and there was no carbon to be cleaned off.

As you know, on February 21, 1990, 1 had the head removed for engine work (unrelated to the use of your product). The pictures taken at that time, especially the ones of the cylinder heads and exhaust port, show the complete absence of any carbon. When you can read the numbers on top of each valve, you certainly have a clean cylinder head These pictures, taken after nearly 400,000 miles of PVI use, continue to confirm the product's capability to keep an engine clean-as-new internally.

I also put your Platinum Vapor injector device on the diesel Thermo-King refrigeration unit on my trailer. The unit was installed on 9/10/86. Within the first ten minutes after installation, the engine started to run more smoothly with less smoke. After running for twenty minutes, I stopped the engine and waited five minutes. Then I turned the thermostat to the maximum cold setting and restarted the engine. Under normal conditions when this is performed, the engine starts under such a heavy load that the engine starts slowly and is badly over-fueled, causing heavy, black smoke and extreme vibration.

As you know, this is not an accepted method of re-starting a refrigeration unit. With your PVI device on, I started the engine to test for smoke and vibration, and to my total surprise, the smoke was approximately one-half and the vibration was less than .one-half. I repeated this procedure after three minutes running and the engine started more easily and with less smoke and vibration. Eventually, the smoke and vibration were almost gone, and the pre-combustion knock was much less than normal.

GeaLlemen, the required major maintenance on the reefer engine is 10,7000 'hours, which consists of removing the head to remove the carbon buildup on the head and valves and to replace all necessary parts, including the injectors. My unit was running so smoothly that I kept using it without doing the 10,000-hour maintenance because my oil consumption had dropped from one gallon for 105 t* 115 hours to one gallon for approximately 500 hours. There being no smoke or vibration to be concerned with, I ran the unit to 14,500 hours. I was worried that the rack on the top end was getting some looseness, so I had the unit checked for tune-up. The injectors were pulled and inspected for carbon deposit and wear. Usually the injectors cannot be pulled, even at 10,000 hours, because of the carbon buildup on them. Mine not only were pulled, but only needed adjustment, not replacement.

My unit was tested after tune-up against the readings of a brand new unit. To everyone's surprise, my unit, with 14,500 hours, checked just as efficient or better than a brand now unit and without the smoke, vibration, and smell. it now has over 16,000 hours. Since it continues to run without vibration, smoke, or any increases in fuel and oil usage, I do not plan to overhaul before 25,000 hours.

I personally believe that any device that cleans the engine on the top side while cleaning the oil on the bottom side, thereby reducing all pollution's of the diesel engine, cannot be labeled as "no good" by anyone in their right mind. After all, owners of diesel trucks, cars, and pick-ups need and deserve all the service and benefits that it is possible to get.

More important than the service and benefits of the truck engine are the all important facts that:

1) The smell is reduced to a negligible level.

2) The smoke is all but eliminated, and with that goes the air pollution complaint about the diesel truck engine.

3) Removal of the sulfur from the engine oil and the fuel oil during combustion is the most significant because all of us have to breathe the air.

As a concerned truck owner, I look forward to the time that all diesel engines are using your device. Keep up the good work.

Sincerely,

Re: Platinum Vapor Injection

Dear Mr. Silver:

In connection with the demonstration project currently being conducted on 15 vehicles owned by County of Los- Angeles, you have requested that we provide estimates of cost savings which can reasonably be expected as a result of the installation of the PVI on the County's diesel vehicles.

We have been unable to obtain from the County the necessary data to make these estimates for your specific fleet of vehicles. This information includes fuel consumption (per vehicle), oil consumption (per vehicle), oil change interval, tune-up interval, fuel injector life span, major overhaul intervals, average engine life for each fleet of vehicles, and maintenance labor costs. We have, however, been able to estimate these cost savings for the Public Service Company of New Mexico diesel fleet. These estimates are attached and entitled "Maintenance Expense Reductions (Diesel).

The estimated savings to, County of Los Angeles will not be identical to those estimated, to PNM. However, we believe the economic to the County of Los Angeles, is, illustrated by the cost savings figures provided to PNM. In fact, the savings to the County may be greater because of higher costs in Los Angeles than in Albuquerque.

As you know, these cost savings estimates do not include the significant economic and health benefits, which result from the reduction of pollution. Likewise, these estimates do not include the budgetary savings, which will be realized by the Southern California taxpayers due to the substantially reduced budget, which will be required by the SCAQMD in the event the P.V.I. is installed on all vehicles in California.

Enclosed is a summary of the test results obtained by Valley Detroit Diesel Allison on May 15 and 16. All tests were conducted by Jim Leslie of Valley and were observed by Reno McElvain of Holmes & Narver Services, Inc. Also enclosed are the test results from five Sheriff's buses and five County vehicles. All of these results, were observed and approved in writing by County employees and employees of Holmes & Narver. You will note that the simultaneous reductions in smoke, oxides of nitrogen (NOX), and carbon monoxide (CO) are significant.

You have requested that we consider installing the P.V.I. on one or more of the County's gasoline vehicles. At this time, we are not able to accommodate your request. Enclosed is a copy of a letter we received from the California Air Resources Board. You will note that CARB has not consented to a demonstration project on vehicles owned by the County. This position by CARB is regrettable in light of the urgency of the California air quality problem. As you know, our technology does not "modify a vehicles emission control system" which would subject the technology to the jurisdiction of CARB. This fact notwithstanding, however, we are not inclined at this time to take any action contrary to the CARB letter.

At such time as CARB consents to the installation of the P.V.I. on gasoline vehicles we will be anxious to work with you to conduct a demonstration project similar to the one presently being completed on the County's diesel vehicles. Because of the insistence by CARB that we must obtain an executive order for gasoline vehicles, please be advised that we will be submitting to CARB our application for this executive order within the next couple of weeks. Until this executive order is issued, we are committed to devoting our total efforts and resources to the installation of the P.V.I. on diesel vehicles in California.

As President Bush stated in his Inaugural Address, in regard to our environmental crisis, further debate and study must stop. All of us must commit ourselves to decisive action. The significant benefits which result from use of the P.V.I. have been documented clearly and authoritatively. We look forward to working with Supervisor Antonovich to bring the innovative technology of the Platinum Vapor Injector to the citizens of the State of California.

If you have any questions or need additional information, please call me.
