The patent filed by Eaton Intelligent Power Limited introduces a sophisticated method of operating a system that integrates a hydrogen internal combustion engine with a supercharger.
This innovative approach addresses two primary modes of engine operation: the normal operating mode and the engine braking mode.
In the normal operating mode outlined in the patent, the supercharger plays a crucial role in optimizing the engine’s performance. It operates at a designated first rotational speed, efficiently delivering air to the engine’s intake manifold. This process ensures that the engine receives the necessary airflow to function effectively, facilitating optimal power output and efficiency.
The patent also delves into the engine braking mode. Here, the supercharger’s function is adjusted to a second, distinct rotational speed. This adjustment is coupled with an intentional restriction in airflow to increase the pressure ratio across the supercharger. The increased pressure enhances the engine’s braking capability, providing better control and efficiency without compromising the system’s overall performance.
One of the key advantages of this patented system is its dual operational capability. By adapting the supercharger’s speed and airflow in response to different driving conditions, the system ensures both powerful propulsion and effective braking. Additionally, the integration of hydrogen as a fuel source aligns with global efforts to reduce carbon emissions, promoting a more sustainable transportation option.
