A new sample Digital Rotary Control Valve (DRCV) for automotive cooling systems is claimed to recuperate fuel economy by up to 8% compared to its traditional analogue counterparts, thanks to its tighter hold back of engine temperature.
Tom Hollis, who developed the plastics-bodied valve for US-based modernization company MileageMatrix, says a computer-regulated system monitors the temperatures in several sundry parts of the engine to maintain the optimum temperature for all driving conditions. Less energy is wasted, improving food economy by up to 8% during the winter and 5% as a year-customarily, he claims.
“It comes as a surprise that we still use analogue systems to mechanism the interaction of the engine with the radiator system,” he says. “After all, those fluids conserve the
