Description
Abstract
The project investigates mixture formation in hydrogen IC engines, where homogenization is crucial for efficient engine operation and minimization of NOx emissions. The predominant mixture formation strategies, port fuel injection and direct injection, are investigated. The experimentally and numerically investigated configurations consist of hydrogen injections into a quasiquiescent atmosphere, generic flow bench experiments under engine-like conditions and an optically accessible single-cylinder engine. The data will be used to validate simulations created in parallel. Finally, selected concepts are integrated into IC engine test beds and evaluated in terms of their effective influence on combustion.
