=== Emissions ===
{{see also|Diesel exhaust}}
Diesel engines are combustion engines and, therefore, emit combustion products in their [[exhaust gas]]. Due to incomplete combustion,<ref name="List_1939_1" /> diesel engine exhaust gases include [[carbon monoxide]], [[hydrocarbons]], [[Particulates|particulate matter]], and [[nitrogen oxides]] pollutants. About 90 per cent of the pollutants can be removed from the exhaust gas using exhaust gas treatment technology.<ref name="Dubbel_2018_1191" /><ref name="Reif p. 329">{{Cite book |last=Reif |first=Konrad |title=Diesel engine management : systems and components |date=2014 |publisher=Springer-Verlag |isbn=978-3-658-03981-3 |publication-place=Wiesbaden |page=329 |oclc=884504346}}</ref> Road vehicle diesel engines have no [[sulfur dioxide]] emissions, because motor vehicle diesel fuel has been sulfur-free since 2003.<ref name="Reif p. 331">{{Cite book |last=Reif |first=Konrad |title=Diesel engine management : systems and components |date=2014 |publisher=Springer-Verlag |isbn=978-3-658-03981-3 |publication-place=Wiesbaden |page=331 |oclc=884504346}}</ref> Helmut Tschöke argues that particulate matter emitted from motor vehicles has negative impacts on human health.<ref name="Tschöke Mollenhauer Maier p. 813">{{Cite book |last1=Tschöke |first1=Helmut |title=Handbuch Dieselmotoren |last2=Mollenhauer |first2=Klaus |last3=Maier |first3=Rudolf |date=2018 |publisher=Springer Vieweg |isbn=978-3-658-07697-9 |publication-place=Wiesbaden |page=813 |language=de |oclc=1011252252}}</ref>

The particulate matter in diesel exhaust emissions is sometimes classified as a [[carcinogen]] or "probable carcinogen" and is known to increase the risk of heart and respiratory diseases.<ref>{{Cite web |title=What Are Diesel Emissions?
