LEC makes large engines environmentally friendly
The engines, which the LEC works with, fill rooms and have a cubic capacity of up to 30 litres. This makes it evident that these engines produce significant amounts of exhaust emissions. Therefore, the LEC has made it its mission to increase the efficiency and decrease the amount of polluting emissions made by large engines. They focus on large gas engines and dual-fuel engines, which can operate with diesel or other heavy fuels as well as with gas. For GE Jenbacher the LEC has designed a highly effective combustion concept for their new gas engine. This concept allows for 48,7 percent effectiveness, roughly 25 years ago it was only 37 percent. Considering that one percent augmentation leads to an annual carbon dioxide emission reduction of 750 tons, this is an outstanding result.
The highly complex simulations required for this are made with a supercomputer by Atos. With it the LEC develops models for the simulation of combustion, knocking and pollutant formation. This research is done based on experimental examinations on one-cylinder research engines and 3D-simulations.
Our goal is to create the next generation of environmentally friendly large engines. Andreas Wimmer, CEO and Scientific Director of the LEC Ltd.
