He has made significant contributions to the field of diesel engine technology, holding 2 patents that focus on improving engine efficiency and emissions control. His work is essential in advancing the performance and environmental standards of diesel engines.
Latest Patents
Leu's latest patents include a method for selecting an engine operating point in a multi-mode powertrain system. This method involves monitoring desired axle torque based on operator requests and vehicle speed. When an aftertreatment device requires an increased exhaust gas feedstream temperature, an intrusive engine operation mode is enabled to achieve this temperature efficiently. The method retrieves a plurality of engine power losses corresponding to various intrusive operation points, allowing for the selection of the point with the lowest total power loss.
Another significant patent by Leu is a method for monitoring the light-off temperature of a diesel oxidation catalyst. This method measures the exhaust gas temperature upstream and downstream of the catalyst during the post-injection phase. It determines whether a catalyst light-off has occurred and calculates the surface temperature of the catalyst. This innovative approach allows for real-time monitoring of the catalyst's performance, taking into account its aging process.
