The effects on the exhaust emissions of using a block heater to reduce cold start emissions were investigated. The exhaust was characterized by both regulated and some unregulated exhaust components. The car was tested according to the 1975 Federal Test Procedure (FTP-75) test procedure for regulated emissions at +22, +5 and -15 degree C ambient temperatures. At +5 degree C additional analysis of Polycyclic Aromatic Compounds (PAC) and 2,3,7,8-tetrachloro dibenzo-p-dioxin (TCDD) receptor affinity test was carried out. Reductions of CO and HC emissions are 60 and 65% respectively using a block heater at the lowest ambient temperature. NOx emissions are less affected and even increase marginally in some cases.
