A new type of catalytic converter has been created that improves the efficiency of the converter by focusing on the air to fuel ratio.

By controlling this ratio and maintaining a certain amount of oxidants in the converter better efficiency can be achieved.

The inventors, who have received a US patent for their creation, use a computer to calculate the difference between the amount of oxidants in the converter and the amount that should be in there.

The air to fuel ratio is subsequently adjusted to either produce more hydrocarbons or more oxidants creating a balance.

This means that lower amounts of hydrocarbons and carbon monoxide particles are released into the atmosphere through the tailpipe.

The new technology intends to fix unnecessary complexity and a delay in the reaction that occurs in most catalytic converters without the new system, journalgazette.net reports.
