CONTROL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240229730 titled 'CONTROL DEVICE
Simplified Explanation: The patent application describes a control device for a turbocharger in an internal combustion engine, which includes a turbine and a compressor. The control device is designed to maintain the boost pressure of the turbocharger within a specified range by controlling the turbine and calculating the decrease in compressor efficiency.
- The control device regulates the turbine to keep the boost pressure of the turbocharger at or below a set value.
- It calculates the decrease in compressor efficiency to ensure optimal performance.
- The allowable boost pressure is determined based on the intake air amount in the intake passage.
Key Features and Innovation:
- Control unit manages turbine to maintain boost pressure.
- First calculation unit computes decrease in compressor efficiency.
- Second calculation unit determines allowable boost pressure based on intake air amount.
Potential Applications: This technology can be used in various internal combustion engines to optimize turbocharger performance and enhance engine efficiency.
Problems Solved:
- Ensures the turbocharger operates within safe pressure limits.
- Maximizes compressor efficiency for better engine performance.
