An external source of CO2 gas is used to pressurize the fuel containment system to a pressure greater than the surrounding pressure. An electronic detector capable of detecting CO2 gas is used to scan at least some of the containment system's external surfaces for the presence of the escaping CO2 gas. When the electronic detector senses the CO2 gas an alert system is activated. Once the leak site area is known a leak finding composition of matter is applied to the leak site area in order to identify the exact point of leakage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"EVAP II—Leak verification and detection for vehicle fuel containment systems","description":"An off-board vehicle fuel handling and containment system leak tester that uses CO2 gas in order to find the location of the leak site.
