Additive manufacturing process offers reduction in engine weight of up to 21%
By Jim Gibbins - 1st February 2021
Germany – Aachen-based powertrain developer, FEV Europe GmbH claims weight reduction remains a primary focus for vehicles to achieve lower CO2 emissions. FEV has collaborated with various partners on its LeiMot project (Lightweight Engine Project) to demonstrate how much potential there is to reduce the weight of internal combustion engines. The company states that major components of a baseline diesel engine can be made roughly 21% lighter by using additive manufacturing methods. FEV also says the project has shown the ability to increase the efficiency of engine functions such as cooling and oil circulation.
With a view to future emission reductions and driving dynamics requirements, the aim is to further reduce vehicle mass and increase powertrain efficiency. Modern all-aluminium combustion engines have already reached a very high level in this respect, but further advancement can probably only be accomplished with alternative manufacturing processes, FEV suggests.
