​Universal Catalyst Euro 4/5/6 Honeycomb Ceramic/Metal for Auto Exhaust Purification

Universal Catalyst Euro 4/5/6

EU emission standards are summarized in the following tables. All dates listed in the tables refer to new type approvals. The EC Directives also specify a second date—one year later, unless indicated otherwise—which applies to first registration (entry into service) of existing, previously type-approved vehicle models.

WFEC can supply reliable solution of catalysts for vehicle emission control of Euro 4/5/6 requirements with the following advantages:

• Convert CO, HC, NOx in the exhaust gas into harmless CO2, H2O, N2;
• Excellent cold start performance and triple-effect window performance;
• Excellent high space velocity performance, the conversion rate of the catalyst can reach more than 90% in a high space velocity environment of 80,000h-1;
• Strong hydrothermal stability and anti-toxicity (sulfur, arsenic, phosphorous), little degradation of catalytic performance;
• Low precious metal content, high cost-effective catalyst
