PETRONAS Research & Scientific Services' technical report on CEM Catalyst Fuel System completed.

NEW YORK--(BUSINESS WIRE)--July 17, 1996--The management of Ecology Pure Air International Inc. (EPAI) (formerly known as Mark Four Resources Inc.), in keeping with the company's global marketing strategies, particularly in the Asian region, is pleased to announce completion of a major milestone.

Tests were conducted on June 21-23, 1996 at the PETRONAS Research & Scientific Services Sdn Bhd. (PRSS) Vehicle Emissions Testing Laboratory located in Section 27, Shah Alam, Selangor Darul Ehsam, Malaysia. PRSS is a 100% wholly owned subsidiary of Petronas, a multi-billion dollar integrated oil company in Malaysia and listed on the Kuala Lumpur Stock Exchange.

The tests were described as the "Cold-Start and Hot-Start" emissions test of the European CEC-RF-08-A-85 Reference fuel treated with CEM Catalyst Fuel System using two different models of PROTON WIRA vehicles. The tests were conducted with close supervision by Standards and Industrial Research Institute of Malaysia (SIRIM), an institution affiliated with major standard organizations worldwide which includes British Standards Institution (BSI) and the Canadian Standards Association (CSA).

The objective of the test program is to compare the "Cold-Start and Hot-Start" emissions of CEC-RF-08-A-85 Reference fuel treated with and without CEM Catalyst Fuel System using two different models of PROTON WIRA gasoline vehicles.

In the emissions testing program for the evaluation of CEM Catalyst Fuel System, two different models of PROTON WIRA namely PROTON WIRA 1.6XLi Aeroback-Multipoint injection (Automatic) and PROTON WIRA 1.6XLi Sedan-Multipoint injection equipped with catalytic converter (Automatic) gasoline vehicles were used. Each test vehicle was tested at cold and hot starting using untreated and treated reference fuel. The baseline emissions of each vehicle was established based on the untreated reference fuel emissions measurement.

When using the CEM Catalyst System, overall emissions results show that there was a reduction in both the cold-start and hot-start emissions of the vehicles. For both vehicles, the emissions reduction ranging up to 22% for Carbon Monoxide (CO), 4% for Total Hydrocarbon (THC), and 4% for Nitrogen Oxides (NOx) were observed in cold-start emissions testing, whereas for the hot-start, a reduction ranging up to 54% for CO, 34% for THC, and 22% for NOx were recorded.

As the result of the positive data generated, the company will start to work on establishing a commercial relationship with Petronas.

EPAI is an environmental technology company. It has developed and is in the process of implementing the commercial application of its Combustion Efficiency Management Catalyst (the "CEM Catalyst"), a precombustion device intended to reduce the emission of pollutants in automobiles, motorcycles, lawn mowers and other vehicles and machinery.
