Latest Patents

Among his latest patents, Wei-Jun Yang has developed two significant techniques involving hydrocarbon vapor start processes:

1. **Hydrocarbon vapor start techniques using a purge pump and hydrocarbon sensor**: This patent describes a system where an evaporative emissions (EVAP) control mechanism is integrated into a vehicle. The system includes a purge pump that efficiently pumps fuel vapor to the vehicle's engine. This process is managed by a hydrocarbon (HC) sensor that measures the amount of HC in the vapor. It allows the controller to detect potential cold start conditions, thereby minimizing HC emissions by controlling the flow of fuel vapor to the engine based on real-time measurements.

2. **Evaporative emissions control system including a purge pump and hydrocarbon sensor**: This innovation outlines a similar EVAP control system, focusing on the efficient transfer of fuel vapor from a vapor canister to the engine when engine vacuum conditions are inadequate. The inclusion of a hydrocarbon sensor ensures that the system can precisely measure and control the amount of fuel vapor delivered, ultimately aiding in the reduction of harmful emissions.
