New invention will slash fuel bills
`Mr Rigney said it worked by enabling vehicles to use petrol that normally was spewed into the environment.
He said most cars wasted between 15 per cent and 20 per cent of petrol because they failed to turn it into vapour.
Vaporate added heat to a fuel system, ensuring all petrol was vapourised and used.
Mr Rigney, who spent more than seven years developing the device, said extensive testing had shown four in five family cars and four-wheel-drive vehicles fitted with the device used between 10 per cent and 20 per cent less fuel.
He claimed that in some vehicles fuel use dropped by more than a quarter.’
