Ultrasound Key to More Efficient Engines
A system that uses ultrasound technology to look inside car engines could lead to more efficient engines – and huge fuel savings for motorists.
Ultrasound scans have long been a fundamental tool in healthcare for looking inside the human body, but they have never before been put to use in testing the health of a modern combustion engine. In the Univ. of Sheffield’s Department of Mechanical Engineering, Rob Dwyer-Joyce, professor of lubrication engineering, has devised a method of using ultrasound to measure how efficiently an engine’s pistons are moving up and down inside their cylinders.
