This report describes testing by EPA of the Vehicle Exhaust Emission Control Device (VEECD) retrofit device under Section 32918 of Title 49 U.S.C. Retrofit Devices (RD). The VEECD is described by the developer in the international patent application as an embodiment of air bleed principle. It is intended to be retrofitted to vehicles produced without any, or with earlier-technology emission control systems. The developer claims (RD Application Appendix A) that the valve significantly reduces CO and HC emissions without substantially increasing CO2 or NOx emissions. Incidental city fuel economy enhancement was also claimed. Non-FTP test data obtained for 1986/87 European vehicles from two laboratories in the UK was submitted. This data (Appendix B) was analyzed using the t-test for the difference of constant speed data (30/60/85MPH) at 95% confidence level.
