Requirements for Built-in Services Port for On Board Diagnostics

SAE J 2744-2008 发布历史

This document presents the requirements for a built-in service port to be used in vehicles intended to comply with Enhanced Evaporative Emissions Requirements. The primary function of the Service Port (Valve Assembly-Evaporative Emission Canister Purge Harness Service) is to provide non-destructive access to the evaporative emissions system toenable testing of the integrity of the system. The Service Port is used to introduce air pressure or fuel vapors into, or evacuates them out of, the system. This access may be used for the following evaluations:• Evaporative System Certifications Canister Loading and Purging• End-of-line Testing System Integrity• Service (e.g. OBD MIL on) Leak Location and Repair Verification• In-Use Compliance Testing Canister Loading and Purging• Inspection/Maintenance Testing System Integrity and Purge Check1.1 Mission/ThemeThe Service Port is a component of the Evaporative Emissions Subsystem. It shall be an integral part of the Enhanced Evaporative Emission Subsystem and therefore all requirements of that system must be met.1.2 ClassificationThe primary application of this service port will be passenger cars, and light, medium and heavy duty trucks that are required to have OBD II systems and meet Enhanced Evaporative Emissions Standards. This includes gasoline vehicles,and bi-fuel (gasoline/CNG) vehicles intended for sale in the United States and Canada or other marketplaces that adopt Enhanced Evaporative Emission Regulations similar to those in the United States and Canada.
