Particle Traps

• For land transport, particle traps are becoming a mature abatement technology within the integrated emissions control systems of buses and lorries, and is beginning to be seen on some diesel engined cars.
• They work in conjunction with NOx control equipment by having a very fine ceramic filter where the particulates react with other hot exhaust gases to burn up. They work well only with ultra low sulphur fuel.
• No products for use with marine engines are under development, as cheaper technologies can meet current and foreseen needs.
