GASEOUS FUEL SUPPLY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240247617 titled 'GASEOUS FUEL SUPPLY DEVICE
The abstract describes a gaseous fuel supply device with processing circuitry that controls a direct injection valve and a shut-off valve. The processing circuitry determines the energization time for the direct injection valve based on the pressure of the gaseous fuel supplied. When the temperature of the direct injection valve exceeds a certain value, the processing circuitry initiates an opening-closing process for the shut-off valve.
- The processing circuitry controls the direct injection valve and shut-off valve.
- The energization time for the direct injection valve is determined based on the pressure of the gaseous fuel.
- When the temperature of the direct injection valve is too high, an opening-closing process for the shut-off valve is initiated.
- The opening-closing process switches the shut-off valve between open and closed states based on the pressure of the gaseous fuel supplied.
Potential Applications: - Automotive industry for fuel injection systems - Industrial machinery using gaseous fuels - Energy production facilities utilizing gaseous fuel
Problems Solved: - Efficient control of gaseous fuel supply - Preventing overheating of the direct injection valve - Ensuring safe operation of the fuel supply device

Questions about the technology: 1. How does the processing circuitry determine the energization time for the direct injection valve? - The processing circuitry calculates the energization time based on the pressure of the gaseous fuel supplied. 2. What are the potential risks associated with the overheating of the direct injection valve? - Overheating of the direct injection valve can lead to malfunctions in the fuel supply system and potential safety hazards.
Original Abstract Submitted
a gaseous fuel supply device includes processing circuitry configured to control a direct injection valve and a shut-off valve. the processing circuitry determines an energization time for the direct injection valve based on a pressure of gaseous fuel supplied from a supply passage to the direct injection valve. when a temperature of the direct injection valve becomes greater than a temperature determination value, the processing circuitry starts an opening-closing process that repeatedly switches the shut-off valve between a closed state and an open state. the opening-closing process is a process that brings the shut-off valve into the closed state when the pressure of the gaseous fuel supplied to the direct injection valve is greater than a pressure lower limit value and brings the shut- off valve into the open state when the pressure of the gaseous fuel becomes less than or equal to the pressure lower limit value.
