DIESEL ENGINE SUPERCHARGING SYSTEM WITH EXTERNAL ELECTRIC COMPRESSOR
Reduced diesel consumption in a hybrid generation system with an electric turbocharger
- Electric power generation in remote communities represents a technological challenge that must take into account environmental requirements in terms of GHG emissions and production costs while ensuring continuity of energy supply to consumers.
- Among the resources used in these areas are renewable energy and diesel generators. The latter often operate at low loads characterized by poor performance and high operating and production costs.
- The purpose of this invention is to improve the diesel generators performance (brake specific fuel consumption – BSFC) and increase the penetration rate of renewable energy in remote communities or energy isolated areas in general, thus reducing overall fuel consumption.
- The energy required for the proposed system will be provided by excess production during periods when available wind or solar power exceeds demand, often dissipated or used for heating.
- Storage of excess renewable energy in the form of electrochemical energy (deep discharge battery)
- The stored electrical energy is used to drive an electric motor that will drive the turbocharger to provide the optimal amount of air at the intake.
- Add a turbo compressor driven by an electric motor or modify the turbo compressor that exists in most generators by adding an electric motor.
- Technology developed by Prof. Adrian ILINCA and Sami AYADI (Department of Mathematics, Computer Science and Engineering, L’Université du Québec à Rimouski (UQAR)).
- Reduced fuel consumption
- Increase the penetration rate of renewable energies in the energy systems of isolated sites.
- Improve the performance of diesel engines operating at low loads: efficiency, fuel consumption, GHG emissions, rated operating temperature, proper lubrication, etc.
- Similar overcharging technique is not yet used in energy systems in remote communities but it is used in vehicles.
- Design for retrofit of existing diesel generators
- Less volume compared to other solutions
- Relatively low costs and rapid return on investment
- Downsizing possibility (use a diesel generator of lower rated power with pneumatic hybridization to increase maximum output power)
- Oil companies
- Remote Communities
- Service stations on highways
- Mining industry
- Road, rail and naval transport
- Technology available for licensing
