METHOD FOR LIMITING AN AIR CHARGE OF AN INTERNAL COMBUSTION ENGINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18324029 titled 'METHOD FOR LIMITING AN AIR CHARGE OF AN INTERNAL COMBUSTION ENGINE

Simplified Explanation

The method described in the patent application involves limiting the air charge of an internal combustion engine by determining a maximum permissible pre-controlled charge and an exhaust-gas temperature-dependent delta charge using a PI controller. The total permissible charge is then calculated based on these values, and the air charge of the engine is restricted to this total permissible charge.

  • The method involves using a PI controller to determine the maximum permissible pre-controlled charge and an exhaust-gas temperature-dependent delta charge.
  • The total permissible charge is calculated based on the maximum permissible pre-controlled charge and the exhaust-gas temperature-dependent delta charge.
  • The air charge of the internal combustion engine is limited to the total permissible charge.

      1. Potential Applications
  • Automotive industry for controlling air charge in internal combustion engines.
  • Industrial machinery for optimizing engine performance and efficiency.
      1. Problems Solved
  • Prevents overloading the engine with excessive air charge.
  • Helps in maintaining optimal engine performance under varying conditions.
      1. Benefits
  • Improved engine efficiency.
  • Enhanced engine performance.
  • Reduced emissions.


Original Abstract Submitted

A method for limiting an air charge of an internal combustion engine. A maximum permissible pre-controlled charge and an exhaust-gas temperature-dependent delta charge are determined by means of a PI controller. A total permissible charge is determined on the basis of the maximum permissible pre-controlled charge and the exhaust-gas temperature-dependent delta-charge, and the air charge of the internal combustion engine is limited by the total permissible charge.
