Onboard car emissions monitor
A team from the University of Manchester have used laser technology to create components that accurately monitor levels of carbon dioxide, carbon monoxide and methane directly from your car’s exhaust. Although still under development, it is readily available and expected to be incorporated into on-board diagnostics systems so that drivers can monitor emissions as they drive.
New lasers need to be added in order to monitor additional gases: nitrogen oxide, nitrogen dioxide and specific hydrocarbons.

“This is the first instance of this type of near-IR diode laser sensor being used directly in the exhaust of a static internal combustion engine to measure emissions,” said Dr Philip Martin from The School of Chemical Engineering and Analytical Science (CEAS), one of the paper’s authors.
The team say the components for the device are readily available and the near-IR technology allows highly accurate readings to be taken and also cuts out interference.”
