CONTROLLER AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18454944 titled 'CONTROLLER AND CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE
Simplified Explanation
The patent application describes a controller for an internal combustion engine that calculates the backflow rate of combustion gas into the direct injection valve based on in-cylinder pressure and supply fuel pressure.
- The controller includes a CPU that acquires in-cylinder pressure and supply fuel pressure.
- The CPU calculates the backflow rate, which increases with higher in-cylinder pressure and decreases with lower supply fuel pressure.
Potential Applications
This technology could be applied in the automotive industry for improving the efficiency and performance of internal combustion engines.
Problems Solved
1. Minimizing backflow of combustion gas into the direct injection valve. 2. Optimizing fuel injection processes for better engine performance.
Benefits
1. Enhanced engine efficiency. 2. Improved combustion process. 3. Reduced emissions.
Potential Commercial Applications
Optimizing fuel injection systems in vehicles for better fuel efficiency and reduced emissions.
Possible Prior Art
Prior art related to optimizing fuel injection processes in internal combustion engines may exist, but specific examples are not provided in the abstract.
Unanswered Questions
How does the controller adjust the fuel injection process based on the calculated backflow rate?
The abstract does not detail the specific mechanisms or algorithms used by the controller to adjust the fuel injection process.
Are there any potential drawbacks or limitations to this technology?
The abstract does not mention any potential drawbacks or limitations that may be associated with implementing this technology in internal combustion engines.
Original Abstract Submitted
A controller is used for an internal combustion engine including a cylinder and a direct injection valve that injects gaseous fuel into the cylinder. A CPU of the controller executes acquisition of an in-cylinder pressure that is a pressure in the cylinder during one combustion cycle and a supply fuel pressure that is a pressure of the gaseous fuel supplied to the direct injection valve, and calculation of a backflow rate that is an amount of combustion gas flowing into the direct injection valve from the cylinder during one combustion cycle of the cylinder. In the calculation of the backflow rate, the CPU calculates the backflow rate such that the backflow rate becomes larger as the in-cylinder pressure increases and the backflow rate becomes larger as the supply fuel pressure decreases.
