DENNIS Y. L. LEUNG, B. Sc. (Eng.), M. Sc., D. I. C., M. I. C. E., C. Eng., P. Eng.



The Person

Dennis Y. L. Leung is a professional consulting engineer, project manager, inventor, planner, developer, investor, and businessman. He is also the President, CEO and General Manager of Mach 3 Technologies Group, LLC (for research and development), Mach 3 Manufacturing, LLC (for ecological products to reformulate hydrocarbon fuels), Mach 3 Enterprises, LLC (for business development) and Mach 3 EcoEnergy Management, LLC (for processing, development and production of ecofuels). Through the past 35 years of his career as a businessman as well as a professional engineer / inventor, he has acquired a wide range of experience to compliment his knowledge and skills in various technologies and businesses.

Dennis was born into a prominent Chinese banking family of illustrious ancestry who took shelter in Vietnam to escape political persecution. When the family fortune was lost in the turmoil of the Vietnam War and coupled with the tragic loss of his mother, Dennis took refuge in Hong Kong at the age of nine, alone and separated from his family who eventually fled as refugees to Paris, France.

As an underprivileged adolescent, he had to struggle for his subsistence in order to survive. Hardship strengthened his resolve to excel in whatever he did, including sports, extracurricular activities as well as scholastic achievements. Dennis managed to achieve a healthy balance where his qualities of leadership, ingenuity and management skills were clearly demonstrated. Against all odds he successfully fought his way through keen competition to enter the prestigious engineering school of Hong Kong University where he graduated with his first degree in B. Sc. (Eng.).

His Carreer

In the summer of 1965 Dennis married his gracious bride, Katina, and joined his scattered family in Paris. After spending 18 months in France assisting his father in building up the family business into a roaring success, Dennis set out to the United Kingdom to pursue his professional career. Starting as a trainee engineer at the world renowned firm of Ove Arup and Partners, Dennis went from strength to strength, fortifying himself with hard work, exceptional performance and perseverance that eventually gained him their rare sponsorship for a place at the prestigious Imperial College of Science and Technology and University of London where he earned his post-graduate degrees of M. Sc. and D. I. C. After reaching the epitome of academic excellence, Dennis returned to the engineering firm to gain further experience in professional practice as service to repay his obligations.

His Achievement

By 1973 Dennis and his wife, Katina, immigrated to North America where he began his own engineering company in 1976. Innovation and creativity won him 5 design awards, 2 of which are of the international award category. His ingenuity, tenacity, enthusiasm and problem solving ability have been well regarded by his peers as the "Fixer" with a "Can Do" attitude. Under his direction and management of Dennis Leung & Associates, projects exceeding a total of $500 million have been successfully completed all over North America.

His Vision

Since February 1998 Dennis felt the urgency to take up the serious challenge of the escalating trend of global warming, smog and serious inhaling diseases in the world and the ever rising prices of fossil fuel threatening the well being and livelihood of the large majority of mankind. Dennis is committed to developing means and methods to lessen or even counter such universal problems and to achieve an improvement to the environmental ecology, fuel economy and engine efficiency for millions of internal and/or external combustion engines, turbines, etc. using fossil fuels.

After realizing the inadequate and ineffective means of using oxygenates in a fuel additive to boost the fuel economy and simultaneous reduction of emissions, Dennis embarked onto an entirely different approach contrary to the conventional wisdom. He came to appreciate the significance of comprehensive reduction of exhaust emissions as the best way simultaneously to gain a higher efficiency in fuel consumption.

His Invention

The philosophical approach to achieve such a feat is by devising certain means of breaking down the fuel molecules by separating the clusters of the longer hydrocarbon chains into scattered shorter and smaller ones in the fuel to enhance a more complete and effective combustion. This will enable about 40% instead of only about 25% of the energy produced from combustion of the fuel to be utilized in usual cases while the rest of the fuel in partially oxidized form is wastefully expelled from the combustion chambers of the engine as exhaust emissions polluting the atmosphere!

After years of unsuccessful attempts and acknowledging his initial failures, Dennis, with very special inspirations, finally came up with a non-metallic solution containing only hydrogen, oxygen and carbon like the hydrocarbons in the fuel itself to be capable of effectuating simultaneously a cooler, longer, leaner, cleaner, and more uniform and complete combustion, resulting in generating more power and smoother operation of the engine for a longer engine life with longer maintenance intervals while gaining higher fuel efficiency. This new and unique fuel reformulator called Mach 3 EcoFuel Saver was born in 2001.

The next generation came in October 2003. It was the Mach 3 Super EcoFuel Saver that followed with an improved version called Ultimate ME2 in private label. In late 2006 came the heavy duty version of the fuel reformulator called Mach 3 Super EcoFuel Saver-Heavy Duty (SEFS-HD) for all types of liquid hydrocarbon fuels as gasoline, diesel, bio-diesel, kerosene, and even bunker C (when preheated) or natural gas, propane, butane, etc. in gaseous form with SEFS-HD being applied in a different configuration.

Mach 3 SEFS-HD is applicable for small engines like the 2-stroke motor tricycles, lawn mowers, etc. as well as for large engines of thousands of HP in ocean going ships, tug boats, locomotives, electric power generators, trucks and buses, and heavy mining and farming machineries with up to 44% reduction of NOx, 33% reduction of CO, 7% reduction of HC and 17% effective reduction of CO2 (1% + 16%). Depending on the type and conditions of the engines, up to 23% of fuel savings can also be achieved. SEFS-HD can be utilized as an after market fuel reformulator for individual vehicles as well as for blending the un-reformulated fuel in the oil refineries. After very extensive testing conducted in the United States and in China (for more than 18 months) and subsequent thorough review to prove their validity, Mach 3 ecological products were finally endorsed by PetroChina / Chinaoil (USA), which is one of the largest oil & gas companies in the world.

Dennis is extremely thankful to be able to offer his humble contributions in Mach 3 ecological products to the world for a cleaner environmental ecology, better fuel economy and higher engine efficiency for the mission of "Saving Fuel, Saving the Environment".
