GASEOUS FUEL SUPPLY DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18539286 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 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 based on the pressure of the gaseous fuel supplied.
- When the temperature of the direct injection valve is too high, the shut-off valve is repeatedly switched between open and closed states.
- The shut-off valve is closed when the pressure of the gaseous fuel exceeds a certain limit, and open when it falls below that limit.
Potential Applications: - Automotive industry for fuel injection systems - Industrial machinery using gaseous fuels - Energy production facilities utilizing gaseous fuel sources
Problems Solved: - Efficient control of gaseous fuel supply - Prevention of overheating in the direct injection valve - Ensuring safe and reliable operation of the fuel supply system
Benefits: - Improved fuel efficiency - Enhanced safety measures - Optimal performance of the gaseous fuel supply device
Commercial Applications: Title: "Advanced Gaseous Fuel Supply Device for Enhanced Performance" This technology can be utilized in automotive vehicles, industrial equipment, and energy production facilities to optimize fuel supply and enhance overall performance.
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 benefits of the opening-closing process for the shut-off valve? - The opening-closing process ensures proper pressure regulation in the fuel supply system.
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.
