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.
  • Liquid cooling allows for enclosed engine installation.
  • Large valve area provides high power across a wide power band.
  • Reliable combustion on heavy fuel with an AFR range of 8:1 to 15:1.
  • Operates in temperatures from -20°C to +55°C.
  • Detonation resistant, minimizing carbon build-up.
  • High reliability and low maintenance with long MTBO.
  • Electronic fuel injection with altitude compensation.
  • Dedicated mounting system for alternators ranging from 100 W to 3 kW.
Engine Models:
  • DF35LC: 35 cc single-cylinder, 2.2 kW power at 8500 rpm, weighs 2.0 Kg.
  • DF70LC: 70 cc twin-cylinder, 4.2 kW power at 8500 rpm, weighs 3.0 Kg.
Applications: Suitable for fixed-wing, rotary-wing, hybrid, marine, and portable power applications. RCV Engines can supply existing units or configure engines for specific platforms, with 3D CAD data available for installation studies.
Additional Features:
  • Cold start assisted with cartridge heaters.
