Rolls-Royce has introduced a new low-emission combustion system for their future engines. The first test was successfully completed in Canada at -20*c, just a month after its first test run. The new demonstrator engine features the Advance3 and the Rolls-Royce UltraFan which also play very important roles in Rolls-Royce goal of the intelligent engine. The intelligent engine created by Rolls-Royce is envisioned to have revolutionary technological abilities and digital capabilities. This engine is monitored by ALECsys (Advanced Low Emissions Combustion System), which monitors weather and thrust requirements for the pilots. It does this by changing the mixture of fuel and air being sent to various parts of the aircraft depending on different factors.
