Product catalog summary
Overview: RCV Engines Ltd offers a range of multi-fuel UAV engines capable of operating on both gasoline and heavy fuel. The engines feature a patented revolving valve system that enhances turbulence for optimal mixture preparation and creates a compact combustion chamber suitable for heavy fuel.
Specifications:
  • Four-stroke cycle for reduced emissions and fuel consumption.
  • Large valve area for high power output and a wide power band.
  • Reliable combustion with an air-fuel ratio (AFR) from 8:1 to 15:1.
  • Operational temperature range from -20°C to +55°C.
  • Detonation resistance and minimal carbon build-up.
  • High reliability and low maintenance with long Mean Time Between Overhaul (MTBO).
  • Electronic fuel injection with altitude compensation.
  • Dedicated mounting system for alternators ranging from 100 W to 3 kW.
Engine Models:
  • DF35: 35 cc single-cylinder engine with 2.2 kW power at 8500 rpm, weighing 2.0 kg.
  • DF70: 70 cc twin-cylinder engine with 4.2 kW power at 8500 rpm, weighing 3.0 kg.
Applications: Suitable for fixed-wing, rotary-wing, hybrid, marine, and portable power applications. RCV Engines can customize engines for specific platforms or applications and provide 3D CAD data for installation studies.
Additional Features:
  • Fuel injection system with low-pressure manifold and altitude compensation.
  • Cold start capability with cartridge heaters.
  • Fuel consumption of 330 g/kW.hr for JP8 fuel.
  • Options for clockwise or anti-clockwise rotation, starter generator, and various cooling methods.
Production and Licensing: RCV Engines offers production engines and can arrange for licensed manufacturing or production supply through partner companies.
