Fuel economy obstacles filtered out

Two innovations are having a dramatic impact on fuel economy in gas-guzzling cars - and other engines and machinery could profit as well

Replacing paper air filters in engines with a new type of three-stage version reduces air resistance and instantaneous pressure drop to the air inlet manifold - while possibly introducing a small amount of catalyst into the air stream to aid combustion.

Alt the same time, a bubbling device introduces a small amount of lubricant - of a type intended to aid combustion and reduce upper cylinder friction losses - while being completely consumed by combustion, so as not to add to exhaust pollutants.

Reducing pressure drop losses in filters on machines of any kind is always a good idea, while improving upper cylinder lubrication has long been a goal.

What the latest versions of these ideas have successfully added to more than one thousand cars is improved long-distance fuel economy – for example, when applied to a Cadillac Six SUV with a 3.6 litre V6 engine, the gain has been from 22 mpg to around 38 mpg.

The technology was developed by Kleen & Green, in St Helens.
