Products and Technologies
At Unicorn Aviation, we present Unicorn EFI, an electronic fuel injection system specifically designed for light aviation. Our technology meets performance, reliability, and environmental requirements. Here is a detailed description of our product, its technical features, and innovations.
Product Description
The Unicorn EFI system is characterized by its complete redundancy, both in software and mechanical aspects, ensuring maximum safety and minimizing the risk of engine shutdown. In the event of sensor failure, the system maintains engine operation, thereby guaranteeing unmatched reliability.
Unicorn EFI is designed to enable piston aircraft engines to operate with E85 bioethanol. This system is adaptable to most carbureted or fuel-injected engines without altering their initial characteristics such as displacement or maximum RPM. It aims to provide an efficient and reliable retrofit solution, thereby reducing the carbon footprint and enhancing the overall performance of the engines.
Technical Specifications
Full Redundancy
The system is fully redundant, with a dual independent injection circuit. This includes separate fuel circuits, fuel pumps, and injectors, ensuring maximum safety in case of failure.
Complete Integration of Bioethanol E86
Unicorn EFI is the first electronic fuel injection system to enable the use of E85 biofuel for aviation, thereby reducing the carbon footprint of flights while offering complete flexibility and unrestricted fuel blending.
3D Printing
The use of 3D printed parts reduces the environmental impact compared to traditional machining and decreases the system's weight by 1 to 2 kg compared to current solutions.
Optimized engine management
The fuel mixture management is optimized through a set of sensors, ensuring maximum efficiency and reduced fuel consumption.
How the system works
Electronic Fuel Management
The core of the Unicorn EFI system is its electronic control unit (ECU) which manages fuel injection in real-time. The ECU uses sensors to monitor various engine parameters and adjust fuel injection accordingly.
Engine RPM sensor
Intake air temperature sensor
Intake pressure sensor
Throttle position sensor
Engine temperature sensor
Precise fuel injection
The ECU controls the fuel injectors to provide the exact amount of fuel needed for each engine cylinder. This ensures optimal combustion, thereby improving engine performance and efficiency.
Multipoint injection
Precise control of fuel metering
Adaptability to changing flight conditions
Operation in FlexFuel mode
Unicorn EFI is capable of operating with all types of fuels: SP98, UL91, 100L, e85, e100. All these fuels can be mixed in any proportion. Unicorn EFI adapts by perfectly adjusting to all mixtures.
Reduction of greenhouse gas emissions
Compatibility with more environmentally friendly fuels
Ability to use locally available fuels
Redundancy and Safety
Safety is a priority for Unicorn EFI. The system is designed with complete redundancy to ensure maximum reliability, even in the event of failure of certain components.
Independent dual fuel circuit
Redundant ECU with automatic switchover in case of failure
Continuous operation in case of sensor failure
Use of 3D Printing
Unicorn EFI uses 3D printed parts, which reduces the overall weight of the system and improves energy efficiency. 3D printing also allows for customization and optimization of components for maximum performance.
Reduction of system weight
Eco-friendly manufacturing with less waste
Possibility of complex and optimized design
Advantages of the Unicorn EFI
Improvement of Safety
Safety is at the heart of Unicorn EFI's design. With a dual independent fuel circuit and complete ECU redundancy, the system ensures continuous operation even in the event of critical component failure. This enhanced reliability minimizes the risk of engine shutdown in flight, thereby providing peace of mind to pilots.
Ecology
Unicorn EFI is designed to be environmentally friendly. By enabling the use of E85 bioethanol, the system reduces greenhouse gas emissions and contributes to a cleaner environment. Additionally, the use of 3D-printed parts reduces the carbon footprint associated with component manufacturing.
Fuel economy
Thanks to precise and optimized fuel injection management, Unicorn EFI enables significant savings in fuel consumption. By adjusting the amount of fuel injected in real-time, the system ensures efficient combustion and reduces losses.
Increase in flight range
By reducing fuel consumption, Unicorn EFI increases flight range. Pilots can thus cover longer distances without having to worry about refueling frequently, which is particularly advantageous for long-haul flights and endurance missions.
