ENGINE CONTROL APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240328368 titled 'ENGINE CONTROL APPARATUS
The engine control apparatus described in the patent application involves controlling the injector and ignition plug of an engine to switch between different combustion modes based on the required torque of the engine. These combustion modes include spark ignition (SI) combustion of gasoline fuel, first homogeneous charge compression ignition (HCCI) combustion of reformed fuel without ignition, second HCCI combustion of reformed fuel with ignition, and diffusion combustion of reformed fuel without ignition.
- The controller switches the combustion mode to second HCCI combustion when the required torque is less than a first predetermined value.
- The controller switches the combustion mode to first HCCI combustion when the required torque is equal to or greater than the first predetermined value but less than a second predetermined value.
- The controller switches the combustion mode to SI combustion when the required torque is equal to or greater than the second predetermined value but less than a third predetermined value.
- The controller switches the combustion mode to diffusion combustion when the required torque is equal to or greater than the third predetermined value.
Potential Applications: - Automotive industry for improved engine performance and efficiency. - Power generation for more efficient combustion processes. - Aerospace industry for enhanced propulsion systems.
Problems Solved: - Optimization of combustion modes based on required torque. - Efficient utilization of reformed fuel for different combustion processes.
Benefits: - Enhanced engine performance and fuel efficiency. - Reduced emissions and environmental impact. - Improved overall combustion process control.
Commercial Applications: The technology can be applied in automotive engines, power generation systems, and aerospace propulsion systems to optimize combustion processes and improve overall efficiency.
Questions about the Engine Control Apparatus: 1. How does the controller determine the required torque of the engine? 2. What are the specific benefits of using reformed fuel in different combustion modes?
Original Abstract Submitted
engine-control-apparatus includes: engine including injector injecting fuel into combustion-chamber and ignition-plug igniting air-fuel-mixture in combustion-chamber; and controller controlling injector/ignition-plug to switch combustion-mode based on required-torque of engine. combustion-mode includes: si-combustion of gasoline-fuel with ignition; first-hcci-combustion of reformed-fuel without ignition, reformed-fuel being obtained by reforming portion of gasoline-fuel into peroxide; second-hcci-combustion of reformed-fuel with ignition; and diffusion-combustion of reformed-fuel without ignition. controller controls injector/ignition-plug to switch combustion-mode: to second-hcci-combustion when required-torque is less than first-predetermined-value; to first-hcci-combustion when required-torque is first-predetermined-value or more and less than second-predetermined-value larger than first-predetermined-value; to si-combustion when required-torque is second-predetermined-value or more and less than third-predetermined-value larger than second-predetermined-value; and to diffusion-combustion when required-torque is third-predetermined-value or more.
