CONTROLLER FOR HYDROGEN ENGINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240175401 titled 'CONTROLLER FOR HYDROGEN ENGINE

Simplified Explanation

The ECM calculates a peak value of an in-cylinder pressure before ignition based on the operating state of the hydrogen engine. When the peak value of the in-cylinder pressure before ignition exceeds a threshold value, the ECM performs an advancement correction of the ignition timing such that the peak value becomes less than or equal to the threshold value.

  • Explanation of the patent/innovation:
 * The ECM (Engine Control Module) in a hydrogen engine calculates the peak in-cylinder pressure before ignition.
 * If the calculated peak value exceeds a set threshold, the ECM adjusts the ignition timing to ensure the peak value is below or equal to the threshold.
  • Potential applications of this technology:
 * Automotive industry for hydrogen-powered vehicles.
 * Energy production using hydrogen engines.
  • Problems solved by this technology:
 * Preventing engine damage due to excessive in-cylinder pressure.
 * Optimizing engine performance and efficiency.
  • Benefits of this technology:
 * Improved engine reliability and longevity.
 * Enhanced fuel efficiency and reduced emissions.
  • Potential commercial applications of this technology:
 * Hydrogen-powered vehicle manufacturers.
 * Engine control system developers.
  • Possible prior art:
 * Research on engine control systems for traditional internal combustion engines.
 * Studies on hydrogen engine performance and optimization.
  1. Unanswered Questions:
    1. How does the ECM determine the threshold value for the peak in-cylinder pressure?

The exact method or algorithm used by the ECM to set the threshold value is not specified in the abstract. Further details on this process would provide a clearer understanding of the innovation.

    1. What are the specific parameters of the advancement correction of the ignition timing?

The abstract mentions an advancement correction of the ignition timing, but the specific parameters or criteria for this adjustment are not detailed. More information on how the ECM modifies the ignition timing would be beneficial for a comprehensive understanding of the technology.
