Rolls-Royce Lean-Burn Combustion Engine Starts Spinning

Rolls Royce Lean-Burn Combustion Engine in Derby, UK

Rolls Royce, the world's most famous airplane engine manufacture tested their newly low emissions combustion system designed for future jets for the first time in their facility in Derby, UK. This engine was an Advanced Low Emission Combustion System known as ALECSys which ran for the first time and it demonstrates the UltraFan program.

Rolls Royce also stated that the lean-burn system improves the pre-mixing of fuel and air prior to ignition which delivers more complete combustion of the fuel and as a result of lower NOx and particulate emissions at the end which will improve the fuel economy of the customers and as well as the environmental performance.

Rolls Royce received funds for this program by the European Union by representing Clean Sky Sustainable and Green Engine. Advance3 test engine had the same core architecture used by the UltraFan which ignited last November 2017. And the power gearbox will enable UltraFan to work efficiently at high bypass ratios reaching 70,000hp which was an aerospace record last September 2017.
