Found this one on the news today:

A MELBOURNE invention that claims to slash vehicle petrol bills by up to 20 per cent and reduce harmful engine emissions will go on sale tomorrow.

This is what the distributor has to say about it:

Typically, a fuel injection system only vaporises 80 to 85% of fuel injected into a combustion chamber. The remaining 15 to 20% maintains its liquid form and is wasted through incomplete vaporisation. Vaporate minimises this vapor loss to provide average savings between 10 to 20% on total fuel costs for 6cyl & 8cyl family cars and larger 4WDs.

Vaporate costs about AU $300 and must be installed by a mechanic. Repco (the distributor) claims that normally it can be done in under 2 hours. And there’s a Flash illustration showing how it works on the Vaporate website. It doesn’t seem too complicated, but I just don’t get it at first. I’m neither an engineer nor a mechanic by any means. How does attaching a thick metal ring improve the vaporisation process? I suspected it has something to do with heat, and looks like I’m in the right direction, it uses a clever trick with pressure and temperature as answered by this explanation.
