Aviation piston engine with electronic fuel injection x400

I. Main characteristics

• Model: x400 EFI[cite: 2]
• Type: two-stroke horizontally opposed 4-cylinder piston aircraft engine[cite: 2]
• Cooling method: air[cite: 2]
• Lubrication method: oil mist (mixed lubrication system)[cite: 2]
• Working volume (cubic capacity): 400 cc cm (400 cc)[cite: 2]
• Minimum stable speed: ≤ 1200 rpm[cite: 2]
• Maximum power: 48 hp / 35 kW at 6400 rpm[cite: 2]
• Specific fuel consumption:
  • 1) Cruise mode: ≤ 380 g/(kWh)[cite: 2]
  • 2) Maximum power mode: ≤ 480 g/(kWh)[cite: 2]
• Fuel: gasoline with an octane rating of 92 and higher (mixture ratio with oil for two-stroke engines 50:1)[cite: 2]
• Resource (Service life):
  • 1) Time to first overhaul (TBO): ≥ 250 h[cite: 2]
  • 2) Total resource: ≥ 500 h[cite: 2]

II. Weight and dimensions

• Engine net weight: 15 kg (including engine block, intake and exhaust components, electronic injection control unit)[cite: 2]
• Dimensions (L×W×H): 370 × 320 × 280 mm[cite: 2]

III. Fuel supply and control

• Fuel supply system: electronic fuel injection (EFI)[cite: 2]
• Control method: capable of receiving commands from the control computer (or integrated on-board computer) and adjusting engine speed accordingly; capable of transmitting to the control computer parameters of throttle position, speed, intake temperature, cylinder temperature, exhaust gas temperature, etc.[cite: 2].

IV. Startup and power generation

• The engine has an electric start function:
  • 1) Number of starting attempts: the engine must start successfully within 3 attempts[cite: 2].
  • 2) Low Temperature Starting: The engine can be started in low temperature conditions down to -40°C (use of the included preheating equipment is acceptable)[cite: 2].
• Generation power: ≥ 2 kW[cite: 2].

V. Environmental Conditions (Adaptability)

• Operating temperature: -50°C to +55°C (start at -40°C, auxiliary heating possible)[cite: 2].
• Storage temperature: -50°C to +65°C[cite: 2].
• Relative Humidity: (95±5)% (at 30°C ~ 60°C)[cite: 2].
• Vibration: ≥ 2g (15Hz ~ 500Hz ~ 15Hz)[cite: 2].
• Shock loads: vertically ≥ 20g, along the transverse and longitudinal axes ≥ 15g[cite: 2].
• Low pressure: Capable of withstanding low pressure conditions equivalent to an altitude of 7000 m[cite: 2].
• Salt fog: is resistant to salt spray[cite: 2].
• Mold: is resistant to mold fungi[cite: 2].
• Rain: Provides protection from moderate rain[cite: 2].
• Application altitude: capable of starting and operating normally in high mountain conditions at an altitude of up to 5000 meters[cite: 2].
