TORQUE COMPENSATION FOR AIR/FUEL SWITCHING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18171417 titled 'TORQUE COMPENSATION FOR AIR/FUEL SWITCHING

The abstract of the patent application describes a vehicle with processors that can select an air/fuel ratio for the engine different from the stoichiometric ratio, as well as a torque request and load request for the engine based on this ratio, and determine an output to a throttle actuator accordingly.

  • The vehicle includes processors that can select a non-stoichiometric air/fuel ratio for the engine.
  • The processors can also choose a torque request for the engine.
  • Based on the torque request and selected air/fuel ratio, the processors determine a load request for the engine.
  • An output to a throttle actuator is then determined based on the load request for the engine.

Potential Applications: - Automotive industry for improved engine performance and efficiency. - Emission control systems for reducing harmful pollutants. - Engine tuning and optimization for various driving conditions.

Problems Solved: - Enhances engine performance by optimizing air/fuel ratio. - Improves fuel efficiency by adjusting torque and load requests. - Reduces emissions by controlling engine parameters more effectively.

Benefits: - Increased engine efficiency and power output. - Reduced fuel consumption and operating costs. - Lower emissions and environmental impact.

Commercial Applications: Title: "Advanced Engine Control System for Enhanced Performance" This technology can be used in automotive manufacturing for vehicles with improved engine control systems, as well as in aftermarket tuning and performance enhancement services.

Questions about the technology: 1. How does the selection of a non-stoichiometric air/fuel ratio impact engine performance? - The selection of a non-stoichiometric air/fuel ratio can optimize combustion efficiency and power output in the engine. 2. What are the potential drawbacks of adjusting the air/fuel ratio away from stoichiometry? - Adjusting the air/fuel ratio away from stoichiometry may lead to increased emissions or reduced fuel efficiency in certain operating conditions.


Original Abstract Submitted

A vehicle includes one or more processors configured to select an air/fuel ratio for the engine that is different from the stoichiometric air/fuel ratio. The one or more processors are further configured to select a torque request for the engine, determine a load request for the engine based on at least the torque request and the selected air/fuel ratio, and determine an output to a throttle actuator based on the load request for the engine.
