RCV Engines Ltd has a range of multi-fuel UAV engines that can operate equally well on gasoline or heavy fuel. The RCV combustion system is based on a unique patented revolving valve, that generates a high level of turbulence for good mixture preparation and creates an ideal compact combustion chamber for heavy fuel operation.
• Four-stroke cycle for low emissions and fuel consumption
• Liquid cooling enables enclosed engine installation
• Large valve area gives high power with a wide power band
• Reliable combustion and power on heavy fuel from 8:1 to 15:1 AFR
• Excellent starting over a wide temperature range -20°C to +55°C
• Resistant to detonation – heavy fuel operation without de-rating
• No combustion chamber hot spots – minimising carbon build up
• High reliability, low maintenance with long MTBO:
o No injectors in the combustion chamber to carbon up
