Lanos S Sedan L4-1.6L DOHC D-TEC MFI (2001)
Component Locator
The LANOS is equipped with an On Board Diagnostic Stage II (OBD-II) system to meet enhanced emission control requirements. Within this OBD-II
system, an On Board Refueling Vapor Recovery (ORVR) system has been developed and equipped to meet enhanced evaporative emission control
requirements during vehicle moving, parking, and refueling at gas stations. The Daewoo ORVR system adopts one canister to collect both evaporative
vapors during the moving & parking as well as refueling vapor. Collected vapor is consumed by the engine though the intake manifold during vehicle
operation. The mechanism of Daewoo ORVR system to meet the ORVR requirement is to create suction inside filler neck by the aid of fuel flow through
a reduced diameter section in the filler pipe.
Therefore, Daewoo ORVR system adopts the so called "Liquid Trap" or "Liquid Seal" system that assures the long term durability.
The Daewoo ORVR system provides nozzle compatibility with conventional and stage II vapor recovery nozzle. The Daewoo ORVR system has been
designed to have the following functional features.
-
To collect refueling vapors and to route to canister.
-
To provide nozzle compatibility with conventional and stage II vapor recovery nozzles.
-
To provide fill shut off signal.
-
To prevent canister from liquid fuel during normal driving and vehicle rollover.
