METHOD OF HEATING CATALYST THROUGH SYSTEM COOPERATION AND VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18367110 titled 'METHOD OF HEATING CATALYST THROUGH SYSTEM COOPERATION AND VEHICLE
Simplified Explanation
The patent application describes a method of heating a catalyst through system cooperation implemented by a vehicle to enable the start of an engine at part load among engine operation modes, even in cold quick acceleration situations, by locking up an engine clutch through system cooperation between controllers of an engine management system (EMS) and a hybrid control unit (HCU). This is achieved by applying a lock-up CH control logic that retards a lock-up CH ignition angle compared to an idle CH control logic of the conventional method, improving regulation responsiveness, fuel efficiency, and merchantability.
- The method involves heating a catalyst through system cooperation in a vehicle.
- It enables starting the engine at part load even in cold quick acceleration situations.
- The system cooperates by locking up an engine clutch.
- Information is exchanged between controllers of an engine management system and a hybrid control unit.
- A lock-up CH control logic is applied to retard the lock-up CH ignition angle compared to idle CH control logic.
- This improves regulation responsiveness, fuel efficiency, and merchantability.
Potential Applications
The technology can be applied in vehicles with hybrid systems to improve engine performance and reduce emissions.
Problems Solved
1. Starting the engine at part load in cold quick acceleration situations. 2. Heating the catalyst efficiently for optimal engine operation.
Benefits
1. Improved regulation responsiveness. 2. Enhanced fuel efficiency. 3. Better merchantability of the vehicle.
Potential Commercial Applications
Optimizing engine performance in hybrid vehicles for better fuel efficiency and reduced emissions.
Possible Prior Art
There may be prior art related to engine heating systems in vehicles, but specific information is not provided in the abstract.
Unanswered Questions
How does the system cooperation between the controllers improve fuel efficiency?
The abstract mentions that the technology improves fuel efficiency, but it does not explain the specific mechanisms through which this is achieved.
What are the potential challenges in implementing this method in different types of vehicles?
While the abstract highlights the benefits of the technology, it does not address any potential challenges or limitations that may arise when implementing it in various vehicle models.
Original Abstract Submitted
A method of heating catalyst through system cooperation implemented by a vehicle may enable the start of an engine of a part load among engine operation modes to heat a catalyst even in a cold quick acceleration situation with a lock-up CH control by locking up an engine clutch through system cooperation implemented by mutually exchanging information between controllers of an engine management system (EMS) and a hybrid control unit (HCU) by applying a lock-up CH control logic which retards a lock-up CH ignition angle compared to an idle CH control logic of the conventional method, thereby improving the regulation responsiveness, fuel efficiency, and merchantability relatively compared to the idle CH even while having the advantages of the idle CH in which quick lambda feedback control for an engine is possible.
