A new patented ‘clean-burn’ after-market fuel device for diesel engines is said to improve fuel economy by at least 10 percent. The Turbo-3000D Vada is also said to enhance performance and reduce carbon deposits, stack soot, black smoke and toxic emissions. It is said to have been granted patents with 46 claims on the ‘clean-burn’ technology. According to the manufacturer, the device is said to improve combustion efficiency in a natural way, without the use of magnets or electrical components. The clean-burn process is also said to help detergents in the oil and fuel remove and prevent carbon build-up and aids in maximum development of power. The device is expected to become an option to owners of new emission compliant engines. Its properties are expected to help offset losses of fuel economy and horsepower sacrificed to meet new US emission standards.
