Ekonomisk och energieffektiv användning av motorvärmare: beräkning av kallstartstillägg

Economic and energy efficient use of engine heater: estimating cold start effects

Using an engine heater before starting the vehicle is a way to achieve greater energy efficiency and lower emissions in the transport sector. The purpose of this study is to update the potential savings by using engine heaters in a newer vehicle fleet. The tool COLDSTART2014 has been used to update the calculations of cold start effects of fuel and emissions, with respect to parking time, ambient temperature and for vehicles of different environmental class. The report provides answers to how much the cold start effects can be reduce in the regional and national level, provided that the engine heater is used effectively. There is a difference between the different environment classes on how an engine heater is used efficiently. There should be recommendations based on environmental class, parking time and ambient temperature, and not like today when they are solely based on ambient temperature. What constitutes an efficient use of engine heaters also depends on the cost perspective. If you look at socio-economic costs, engine heaters should be used much more frequently and longer than with a perspective of private economy.
