Emissions and Fuel Consumption at FTP Test Cycles at +22°C and -2°C from Vehicles Equipped with Block Heaters 920014

Tests have been performed on California certified vehicle concepts in the Studsvik laboratory of AB Svensk Bilprovning (the Swedish Vehicle Inspection Company). The tests have been part of the test program performed for the national Swedish environment protection board. In this study the aim was to record the emission and fuel economy performance of the best available emission control technology on the market for a proposal on more stringent emission requirements. All the vehicles were supplied with electrical block heaters with a power rating of about 0.5 kW.
This report concentrates on emission results from cold weather starting compared to starting at 22°C, and using blockheater as a mean of lowering emissions at subzero starts.
