Technology developed at the University of Waterloo reliably and affordably increases the efficiency of internal combustion engines by more than 10 per cent.

The product of a decade of research, this patented system for opening and closing valves could significantly reduce fuel consumption in everything from ocean-going ships to compact cars.

“This method has the potential to bring the well-established benefits of a fully variable valve system out of the lab and into production engines because cost and complexity aren’t issues,” said Amir Khajepour, a professor of mechanical and mechatronics engineering at Waterloo.
