We believe that making the world’s best aircraft engines can only happen with the world’s greatest employees.
Selina Motors will meet challenging goals by engaging the talent and passion of people who believe to team's goal.
Combining: 545 HP max. multi-fuel internal combustion engine with direct fuel injection, water cooling, dual spark ignition, two-stroke diesel cycle; brushless electric motor-generator - "a source of additional thrust on takeoff"; 1960mm four-blade variable pitch propeller with feathering and reverse modes. Available in CW and CCW, push and pull versions.
Hybrid is the best
The simultaneous use of BLDC and combustion engine (Hybrid) provides a lot of benefits including the low weight, high electrical power production and auxilary power when it's needed.
The combination of two-stroke diesel cycle with direct fiel injection dramatically decreases the weight excluding valves, camshaft, throttle and other parts. It also makes possible to change the fuel type changing the ECU mode.
A dry sump system has a scavenge pump, external oil tank, oil filter, cooler and main pump followed with oil pressure regulator. Engine oil change intervals can be extended even longer due to the storage of more oil in the reservoir. Scavenge pump is connected directly to the isolated crankcase. The electronic filter clogging control system signals the need to replace the filter.
The duplication of ignition system and adding the emergency fuel ignjection makes the powerplant fail-safe in accordance with aviation regulations.
An optional built-in hydraulic pump simplifies aircraft construction.

The best combo
of weight & BSFC
The 154KG weight combined to high maximum power gives 3,5HP/KG powerplant rate.
The estimate fuel consumption for automobile gasoline 95 is 250g/(kW⋅h). The BSFC for all other types of fuel would be calculated during the prototype engine tests.
Refuel with anything
The universal construction of the engine lets use the big range of fuel types. The Engine Control Unit (ECU) can be switched to the engine operating mode corresponding to the fuel used.
It can be any type of car gasoline from 80 to 100, Avgas or Jet fuel.
Integrated to engine
Push and Pull. Clock-wise and counterclock-wise. Variable pitch with feathering and reverse modes.
The propeller control system includes following subsystems: electronic control panel, electrically controlled hydraulic system and mechanical system inside the spinner.
