Clean Air Power Limited

("Clean Air Power")

Clean Air Power presents its MicroPilot technology at the Future Powertrains Conference

Clean Air Power (AIM:CAP), the developer and global leader in compression-ignited natural gas engine systems for heavy duty vehicles presented an update on its second generation MicroPilot technology at the Future Powertrains Conference on 25 February 2015.

The presentation given at the conference highlighted test results from the Company's MicroPilot research and development programs, including its partnership with Brunel University, London, that demonstrate that MicroPilot technology can deliver over 90% substitution of diesel with natural gas, along with a 10% improvement in both power and torque and a 60% reduction in NOx emissions compared to conventional dual-fuel technology.

About Clean Air Power

Clean Air Power designs, develops and delivers compression-ignited natural gas engines for heavy duty transport applications. Clean Air Power's patented MicroPilot and Dual-FuelTM technology enables engines to run on natural gas mixed with diesel (or any suitable combustion fuel) providing the "spark" that ignites the gas. Substituting natural gas for diesel cuts fuel costs, emissions of carbon, nitrous oxide and particulates whilst retaining the original engine's power, efficiency and reliability characteristics. Clean Air Power operates in the US, Europe, Russia and Australia and has two commercial divisions:

Dual-Fuel™ Vehicle Systems

Delivery of patented Dual-Fuel™ systems which include fully-interfaced systems developed in partnership with truck manufacturers and the Group's Genesis-EDGE system, developed in-house as an after-market solution. Dual-Fuel™ is a type of system that adapt diesel engines to run on a combination of diesel and natural gas whilst retaining engine's basic infrastructure. The Division sells systems to truck manufacturers for on-line assembly, approved partners for after-market installation or direct to customers through its own installation facilities. The Division also undertakes design and development work for governments and truck manufacturers on Dual-Fuel™ and next-generation MicroPilot systems.

Components

Design and manufacture of innovative hydraulic valves, injectors and filters for natural gas engines sold to truck manufacturers around the world.

Initially founded in the USA in 1991, around £50m has been invested in developing the technology with the result that 69 patents are currently held or pending. The holding company of the Group is based in Bermuda with operational subsidiaries in the UK, the USA and Australia. The Group was admitted to the AIM market of the London Stock Exchange in February 2006.
