En busfärsk undersökning....dieselmotor
Det framgår dock inte om man räknar med avgasmänden från värmaren då detta bara är någon sammanfattning, men
Results Summary:
Engine start-up temperature has a significant impact on the emissions levels emitted by the engine.*
PM emissions were reduced by 66 percent by pre-heating the engine during the cold weather conditions. Pre-heating also provided a 27 percent reduction in PM emissions during normal ambient conditions. This will help in longevity of the DPF life and can avoid more frequent regenerations and cleaning intervals.* NOx emissions were reduced by around 40 percent by pre-heating the engine to 155 degrees Fahrenheit.*
The test results shows a 29 percent reduction in CO during winter conditions, and a 62 percent reduction during normal ambient conditions.*
Pre-heating the engine does not have a significant effect on the Hydrocarbon emissions.*
