FUEL SYSTEM FUEL VAPOR RECIRCULATION SYSTEM AND METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240026843 titled 'FUEL SYSTEM FUEL VAPOR RECIRCULATION SYSTEM AND METHOD
Simplified Explanation
The abstract describes a fuel vapor recirculation system that includes a filler neck, a fuel tank, a fuel vapor cannister, and various valves. The system is designed to collect fuel vapor and selectively supply it to the intake manifold of a vehicle.
- The filler neck is used to receive a refueling nozzle that dispenses fuel into the filler neck.
- The fuel tank receives fuel from the filler neck through an inlet check valve, which is normally closed.
- The check valve opens when fuel is dispensed into the fuel tank and also includes a vent hole that is always open.
- The fuel tank also includes a fuel limiting vent valve and a grade limit vent valve.
- The fuel vapor cannister collects fuel vapor and supplies it to the intake manifold of a vehicle.
- The fuel vapor recirculation manifold receives fuel vapor only from the fuel limiting vent valve and the grade limit vent valve in the fuel tank, and not directly from the filler neck.
Potential Applications:
- This fuel vapor recirculation system can be used in vehicles to reduce emissions and improve fuel efficiency.
- It can be implemented in various types of vehicles, including cars, trucks, and motorcycles.
Problems Solved:
- The system helps to prevent the release of harmful fuel vapors into the atmosphere.
- It ensures that fuel vapor is properly collected and recirculated, reducing pollution.
Benefits:
- Reduces emissions and improves fuel efficiency.
- Helps to comply with environmental regulations.
- Enhances the overall performance of the vehicle.
Original Abstract Submitted
a fuel vapor recirculation system includes a filler neck adapted to receive a refueling nozzle that dispenses fuel into the filler neck. a fuel tank receives fuel from the filler neck through an inlet check valve. the check valve is disposed in the fuel inlet opening and is normally closed. the check valve opens when fuel is dispensed into the fuel tank. the check valve defines a vent hole that is always open. the fuel tank also includes a fuel limiting vent valve and a grade limit vent valve. a fuel vapor cannister collects fuel vapor and selectively supplies fuel vapor to an intake manifold of a vehicle. the fuel vapor recirculation manifold receives fuel vapor only from the fuel limiting vent valve and the grade limit vent valve in the fuel tank and does not receive fuel vapor directly from the filler neck.
