Default Enviro Cat Reduces diesel emissions...

I found this out on the VW news group, I believe the gentleman who put it out there is a Fred TDI page member... If so, please tell us more about your testing!!


<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>
TORONTO--(BUSINESS WIRE)--Jan. 12, 2000--Environmental Solutions Worldwide, Inc., (OTC BB: ESWW) developer of the Enviro Cat(TM) catalytic converter is pleased to announce the test results for the Enviro Cat(TM) on a diesel engine.

AutoResearch Laboratories, of Chicago IL, (an EPA recognized Laboratory) that tested the Enviro Cat(TM) prototype in July 1999 for unleaded fuel, approached ESWW with the opportunity to have the ESWW's original prototype retested for diesel fuel, in conjunction with a major auto manufacturer's
diesel engine.

The Enviro Cat(TM) was tested at 4 different loads each at 3 different RPM's. (Revolution's Per Minute). The Enviro Cat(TM) was tested on a 1.9 Litre VW (Volkswagen) - TDI diesel engine, using Commercial No. 2 Diesel.

These tests yielded the following average percentage reductions. (average percentage reductions relevant to base line are as follows): HC -54.47 % CO -81.97 % Nox - 5.83 % HC = Hydro Carbons CO = Carbon Monoxide
Nox = Oxides of Nitrogen

ESWW in conjunction with a third party, are presently analyzing the test results to evaluate the commercial production of the Enviro Cat(TM) for diesel applications.
The company would further like to mention that Popular Science, the worlds largest science and technology magazine, has an article on the Enviro Cat(TM) in the February 2000 issue on page 40 The company intends to announce further corporate updates and developments in the immediate future.

The statements contained in this news release which are not historical facts contain forward - looking information with respect to plans, projections or future performance of the company, the occurrence of which involves certain risks and uncertainties that could cause the company's actual results to differ materially from expected results. Such risks include the timing of implementation and the scope and success of the program described herein.

Default Re: Enviro Cat Reduces diesel emissions...

It looks like an effective catalytic converter for the reduction of carbon monoxide and unburnt hydrocarbons, areas in which the TDI already excels. Only a 6% reduction in oxides of nitrogen, which is exactly where the TDI would have problems meeting future standards. Particulate emissions, another problematic area, were not at all addressed in this report.
