Novel valves for smoother, efficient engines

Camcon is currently developing a prototype valve to reduce toxic emissions and improve the efficiency of jet aircraft by controlling how fuel is injected into the combustion chamber

Camcon is currently developing a prototype valve to reduce toxic emissions and improve the efficiency of jet aircraft by controlling how fuel is injected into the combustion chamber.

In experiments at the Berlin Technical University, Camcon Binary Actuation Technology (BAT) valves have been also confirmed to reduce the front-end high-pitched noise emitted by jet engine blades by more than 20 decibels at critical frequencies.

The technology also offers the potential to reduce the exhaust component of rear jet noise by actively modulating exhaust gases and combining them with the air, to reduce the 'roar effect' vortices immediately behind the engine.

The European Advisory Council for Aeronautic Research has set targets of reducing perceived noise to one half of current average levels, 50 per cent reduction in CO2 emissions per passenger per kilometre, as well as 80 per cent cut in nitrogen oxide emissions by 2020.

"The EU regulations have put a lot of pressure on the aviation industry to cut noise and toxic emissions pollution," said Ian Anderson, COO, Camcon Technology.

"Our research leads us to believe that the Camcon Binary Actuating Technology can offer the industry the answer to this continuously escalating problem." The high-speed, low energy consumption and long life characteristics of the Camcon binary actuator is set to have a considerable impact in a number of industries.

In addition to the specific application being developed for the aviation industry, the technology is appropriate in other areas including gas and liquid flow control, remote location and sub-sea oil services, automotive engine control and noise pollution reduction in the aviation industry.
