Surprisingly high emissions from fuel-powered auxiliary heaters in cars
Fuel-powered auxiliary heaters can be significant sources of particulate emissions from vehicles, a new study from Finland shows.Heaters, sold under such well-known brand names as Webasto and Eberspächer, among others, are used in both passenger cars and heavy-duty vehicles to preheat the engine and provide additional cabin heating while driving. Emissions from heaters are not regulated, although they are widely used in especially colder regions, such as Finland. Therefore, they can have a significant impact on local air quality, and even on regional or global emissions budgets.
