1. Summary (Abstract)

In an era of global transition toward electrification, traditional internal combustion engines are reaching their thermodynamic and environmental limits. However, the need for high energy-density propulsion systems that are independent of heavy battery packs has never been greater. The answer to this engineering challenge is Alfa Hawk – a radically new engine concept that combines the advantages of extreme downsizing, electronic fluid control and advanced energy recuperation. Developed within the company SvetoLet, Alfa Hawk changes the paradigm of the relationship between power, mass and thermal efficiency.

2. Legacy: From the ekoD project to the Alfa Hawk architecture

The "Alfa Hawk" project was created on the foundations of experience and research carried out during the ekoD project. While ekoD served as a pioneering platform for optimizing combustion, reducing harmful emissions and mechanical refinement, Alfa Hawk represents a qualitative leap. It takes over the ecological principles of the ekoD project and implements them in a completely new, protected thermodynamic architecture designed for maximum power density.

3. The technological challenge of today

Conventional ICE engines suffer from inherited shortcomings:

• • Pumping losses: Energy spent on drawing in air and expelling exhaust gases, which reduces efficiency.
• • Fixed compression: The engine cannot adjust its compression ratio in real time to specific power demands or fuel type.
• • Thermal losses through the exhaust: Unused kinetic and thermal energy leaving the cylinder.

4. Innovation: The "Alfa Hawk" concept

Alfa Hawk abandons traditional cycles in favor of an advanced, electronically controlled hybrid cycle. Without revealing the protected gas-exchange mechanisms, the key innovations of this system include:

• • Fluid management: Through an innovative cylinder filling and emptying system, Alfa Hawk eliminates traditional pumping losses. Air is not simply drawn in, but is precisely metered into the combustion chamber under high pressure, enabling the formation of a homogeneous mixture.
• • Dynamic variable compression: Owing to specific control of the operating phases, the engine can change the effective compression ratio independently of expansion. This allows it to operate on different fuels and transition between different ignition regimes.
• • Synergy of electronics and boosting: Alfa Hawk integrates an advanced, fast-response electric compressor system with an exhaust-energy recovery system. The result is a closed energy loop in which the engine independently generates the electrical power needed for its own boosting, without mechanical losses on the crankshaft.

5. Key advantages

• 1. High power density: Due to its specific operating frequency and level of boosting, Alfa Hawk offers a horsepower-per-liter (HP/l) and power-per-kilogram (kW/kg) ratio that surpasses conventional power units.
• 2. Multi-fuel operation: Software-defined mechanics allow the engine to be adapted to different fuels without changing the engine block hardware.
• 3. Compactness: The design enables a drastic reduction of overall dimensions, making it ideal for integration into tight spaces.

6. Fields of application

Thanks to its flexibility, low mass and high reliability, the Alfa Hawk platform is designed for:

• • Vehicle range extension – range-extender units: An ideal solution for increasing the range of electric vehicles (EVs), where the engine operates in an optimal efficiency window as a generator.
• • Light aviation and unmanned aerial vehicles (UAVs): Where the power-to-weight ratio is critical and reliability is imperative.
• • Portable industrial generators: Mobile solutions for delivering large amounts of electrical power to remote locations.

7. Vision for the future

Alfa Hawk is not just an engine; it is a platform that proves that internal combustion, when combined with advanced electronics and advanced fluid thermodynamics, still has a key role in the future of transportation and energy. The development path from the ekoD concept to the Alfa Hawk architecture is proof of Victor Production's commitment to creating innovations that push the boundaries of what is possible.
