Latest Patents

One of her latest patents is an adaptor for a capless fuel tank filler pipe. This invention provides methods and systems for an adaptor that facilitates leak detection testing of a vehicle. The system includes a threaded hollow shaft that can receive a nozzle from a leak detection machine. The hollow shaft is designed to be inserted through the mouth of a filler pipe, featuring a gasket and an end cylinder with an elastic piece to create an airtight seal. This design restricts gas flow through a defined path during leak detection testing, enhancing the reliability of the process.

Another significant patent by DeZelia is a method and system for fuel vapor control. This invention outlines a process for operating an engine to generate vacuum for subsequent leak detection routines. During a selected key-off condition, the starter motor spins the engine unfueled to create intake vacuum. The fuel vapors drawn during this process are stored in an auxiliary canister, which is purged along with the main canister during purging conditions. This innovative approach improves the efficiency of leak detection in fuel systems.
