Clean Air Power Announces Australia Grant:- Dual-Fuel™ Engine Having Multiple Dedicated Controllers Connected by a Broadband Communications Link (granted under Australian Patent 2003208949) covers future development of Dual-Fuel™ technology.

This Australian patent applies to a Dual-Fuel™ engine control system comprising at least two controllers communicating within a Controlled Area Network (CAN). The CAN is the state-of-the-art computer network that enables one electronic control unit (ECU) to speak to another, including any controller in the vehicle that is capable of communication within the CAN.

Currently, all vehicle system communication is managed by CAN technology. By patenting the use of the CAN communication protocol for Dual-Fuel™ applications, Clean Air Power has a competitive advantage and has protected its future products against competitor systems.

The use of the CAN gives Clean Air Power the benefits of the standard communication protocol and delivers the best technical approach for system integration. Clean Air Power holds corresponding patents in US and Europe under Patent No. 6,694,242 and 1,485,599, respectively.

MicroPilot™ – the Next Generation Dual-Fuel™ Technology (US Patent 6,598,584 and EU Patent 1,234,966 titled “Gas-Fuelled, Compression Ignition Engine with Maximized Pilot Ignition Intensity)
In addition to current Dual-Fuel™ technology, Clean Air Power is constantly looking to the future, developing new solutions to cut emissions and reduce operator costs. One such project is MicroPilot™, the subject of a milestone technical paper that showed how engine emissions can be dramatically reduced by lowering the quantities of diesel pilot injections.

This pioneering work showed that smaller diesel pilot injections comprising 1-2 percent of the total fuel, can reduce NOx emissions by over 80 percent, while reducing CO2 emissions even further.

The MicroPilot™ engine produces low emissions that are equivalent to those of a spark-ignited, lean-burn natural gas engine, while retaining the high efficiency and power density of a diesel engine. With recent advances in fuel injection technology, the Directors of Clean Air Power believe that MicroPilot™ could be applied to heavy-duty engines.

The corresponding US patent 6,694,242 was granted in February 2004.

Method and Apparatus for Controlling Transition between Operating Modes in a Multi-Fuel Engine was issued on 18th September 2007, US Patent 7,270,089 This patent discloses the engine control method that enables a smooth transition between operation modes in a Dual-Fuel™ or other multimode engine. Smooth transition between operation modes is crucial to the success of any multi-fuel engine.

The corresponding patent applications have been filed in Europe and Australia.
