Exhaust

There are currently many projects aimed at reducing the air pollution emitted in automobile exhaust, but in the meantime couldn't we just … redirect that exhaust? A new study suggests a possible means of doing so.

We already have devices which detect vehicles that are exceeding the speed limit, or that are too noisy. Now, scientists are working on an unmanned sensor that could be used to sniff out automobiles that are emitting overly-dirty exhaust.

Gearheads love noisy engines, but this enthusiasm is rarely shared by the general public – hence, the UK is trialing new noise camera technology. Just like speed cameras, they'll sit by the roadside watching and listening 24/7 to identify and ticket vehicles that exceed legal noise limits.

We're big fans of Indian's new flat-track inspired streetbike, but its production exhaust detracts significantly from the look we fell in love with. Aftermarket to the rescue! These S&S exhausts bring the FTR1200 back much closer to the look of the original Custom we lost our minds over last year.

​There's a lot of carbon in automobile exhaust. Carbon is also used as a pigment in black ink. The guys at Singapore-based Graviky Labs have combined the one with the other, by harvesting carbon from vehicles' tailpipes to make their own eco-friendly AirInk.

Gas-powered lawnmowers are notorious polluters. Switching to an electric or reel mower is certainly one option, but a team of engineering students from the University of California, Riverside are developing another: an attachment that they claim reduces noxious emissions by over 90 percent.

Controlled Power Technologies (CPT), best known for its VTES electric supercharger, has announced it is working in the area of exhaust gas energy recovery and estimates its new system will be ready for market in five years time.

Cobra has come up with the perfect invention for socially-responsible petrolheads – a remote-control exhaust system. At the push of a button, an electronically controlled flap changes the noise from subdued sportiness to F1-madness.
