CONTROLLER FOR HYDROGEN ENGINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240337226 titled 'CONTROLLER FOR HYDROGEN ENGINE
The abstract describes a patent application for a controller for a hydrogen engine that utilizes an in-cylinder pressure sensor and an air-fuel ratio sensor, along with processing circuitry, to correct a rich deviation in the air-fuel ratio sensor output caused by unburned hydrogen in the exhaust gas.
- The controller includes processing circuitry that calculates a fluctuation amount of combustion pressure based on the in-cylinder pressure sensor output.
- It also calculates a correction amount based on the fluctuation amount to correct the rich deviation in the air-fuel ratio sensor output.
- The correction amount helps adjust the air-fuel ratio to optimize combustion efficiency in the hydrogen engine.
- By utilizing these sensors and processing circuitry, the controller can improve the overall performance and emissions of the hydrogen engine.
- This innovation aims to enhance the efficiency and environmental friendliness of hydrogen-powered vehicles.
Potential Applications: - Automotive industry for hydrogen-powered vehicles - Energy sector for hydrogen fuel cells - Research and development in alternative fuel technologies
Problems Solved: - Correcting rich deviations in air-fuel ratio sensor outputs - Optimizing combustion efficiency in hydrogen engines - Reducing emissions of unburned hydrogen in exhaust gas
Benefits: - Improved performance of hydrogen engines - Enhanced fuel efficiency - Reduced environmental impact of hydrogen-powered vehicles
Commercial Applications: Title: "Hydrogen Engine Controller for Enhanced Performance and Emissions Control" This technology can be used in the automotive industry to develop more efficient and environmentally friendly hydrogen-powered vehicles, potentially leading to a shift towards cleaner transportation options.
Questions about the technology: 1. How does the controller calculate the correction amount to adjust the air-fuel ratio? - The controller calculates the correction amount based on the fluctuation amount of combustion pressure, which is derived from the in-cylinder pressure sensor output. 2. What are the potential long-term implications of implementing this technology in hydrogen engines? - Implementing this technology can lead to significant improvements in the efficiency and emissions of hydrogen-powered vehicles, contributing to a more sustainable transportation sector.
