Emission of Particulates and Chosen Gaseous Exhausts Components During a Diesel Engine Starting Process
MetadataShow full item record
It is very important to reduce harmful emissions in rural areas. One of the ways is to replace old tractors and farm machinery with the modern, equipped with engines of the highest standards. However, the cost of such replacement is very high and not always acceptable, especially for smaller farmers, nevertheless, due to the needs of sustainable agriculture it should be kept up. This work focuses on exhaust harmful emission during a start-up of a diesel engine installed in a small agricultural tractor. Based on measurements and recorded data, calculations of exhaust gas emission were carried out. The results indicate that the engine starting process, and its initial temperature, have a considerable impact on the emissions during the analyzed operation period. The most important is cold start process which is responsible for most harmful pollutants emission during the initial period of engine work. The temperature of cold start is also noticeable for cold starts and for worm starts as well.
