New Electric Field Device Reduces Car Fuel Consumption by 20%

Professor Rongija Tao, from Temple University, invented a device that, applied to the vehicle's fuel line, near the injectors, creates an electric field that reduces the fuel's viscosity, so that smaller droplets are injected into the engine, leading to better combustion and increased fuel efficiency as much as 20%.

Ford Developing Laser Powered Spark Plug for Future Engines

The auto industry is pursuing various ways to implement more effective fuel saving strategies. Some of them are based on the development of new technology, electric motors, batteries, etc and others are just improving classic petrol-fueled engines to run better. Following the second trend, engineers from The University of Liverpool, UK, in collaboration with Ford and UK-based GSI Group developed a prototype engine ignition based on lasers rather than on spark plugs.
