Ricardo Assists Clean Air Power With Low CO2 Technology

SEE ALSO: Dual-Fuel Technology Primer

VAN BUREN TWP., Mich., Sept. 24 -- Clean Air Power Ltd., the developer of Dual-Fuel(TM) combustion technology, has acknowledged the assistance provided by Ricardo in the development of the company's new natural gas-diesel control system for trucks.

Ricardo was contracted by Clean Air Power to modernize the previous product offering in this sector, which enables diesel engines to run on a mixture of natural gas and diesel fuel. As natural gas contains a lower proportion of carbon than diesel, Clean Air Power's patented technology is capable of providing significant CO2 reductions as well as fuel cost savings. The system is also capable of operating on a mixture of biogas and biodiesel, delivering an almost carbon-free powertrain solution. After researching the market, Ricardo identified an available third-party off-the-shelf ECU, which was suitable for heavy duty application as the basis of the new product. Ricardo provided a bespoke software solution using an advanced modeling package to translate the legacy system and auto-generate the production code for the new controller. Using this state-of-the-art software technology, Ricardo was also able to provide new functionality to the controller, including knock control and lambda feedback. This will provide further improvements in emissions and fuel economy, as well as providing new diagnostic capabilities, compatible with new on-board diagnostic (OBD) requirements.

The new control system and its associated Clean Air Power Dual-Fuel(TM) hardware can be retrofitted as an aftermarket device but its benefits are more significant when integrated to existing diesel powertrain or applied at the design stage of a new engine or vehicle. A key advantage of Clean Air Power's patented technology, which uses a small diesel injection to ignite the gas/air mixture, is that the diesel engine and efficiency is fundamentally unchanged and the vehicle can thus operate fully on diesel fuel if the supply of gas is exhausted. The system provides an optimal gas/diesel mix in real-time according to current conditions, ensuring both smooth and efficient combustion. Having developed this new control system, Ricardo is now ideally placed to assist heavy duty engine manufacturers and truck and off-highway equipment manufacturers wishing to integrate Clean Air Power's patented Dual- Fuel(TM) low CO2 technology into their future products.

Stephen Montgomery, Ricardo Director of Control Systems Software, said: "The challenge of developing state-of-the-art control systems and software is central to the effective implementation of the next generation of low emissions, fuel-efficient, combustion systems using both conventional as well as alternative fuels. Our work with Clean Air Power is an example of Ricardo's commitment in this area and demonstrates the value of applying the latest software and control systems technology in order both to enable and improve the operation of an advanced low CO2 combustion concept."

With technical centers and offices throughout Europe, the U.S. and Asia, Ricardo is a leading independent technology provider and deep-content strategic management consultant to the world's transportation sector industries.

DUAL-FUEL^TM  Combining diesel and natural gas for clear cost efficiency

Clean Air Power has pioneered the move towards natural gas by developing Dual-Fuel™ technologies that provide customers with diesel engine performance, cost savings and low emissions.

Clean Air Power's flagship technology is its patented Dual-Fuel™ system, which enables heavy duty diesel engines to operate primarily on natural gas with diesel fuel acting as a "liquid spark plug". By burning up to 90% natural gas, customers benefit from a combination of low emissions and high efficiency.

With the increasing cost of diesel fuel, stringent emissions regulation and the need for a cleaner, quieter environment, Clean Air Power receives constant requests for its technological solutions and has two main product variants for its Dual-Fuel™ technology:

Integrated Product
The integrated product is a solution where the Clean Air Power technology works hand in hand with the manufacturers technology, whereas the Genesis application is a more generic retro fitted solution.

Genesis Product

The Genesis product has currently been developed for the DAF CF85 and Mercedes Axor Euro III platforms in the UK.

Clean Air Power’s Dual-Fuel™ technology has been installed on over 1,600 vehicles worldwide by over 50 companies.

With its unique Dual-Fuel™ technology, Clean Air Power has pioneered an immediate solution to reduce emissions and fuel costs in the truck industry. Dual-Fuel™ enables a 50% natural gas substitution when fitted to a diesel engine, resulting in a carbon saving of 8.4 tonnes a year, based on 200,000km annual mileage; representing a cost saving of 5p/km, or £10,000 per vehicle yearly.
