![]() Carbon dioxide is classified as a "greenhouse gas" and CO 2 emissions are believed to be a leading contributor of global warming. Additional health concerns, including difficulty breathing, have been linked to both short and long exposure to DPM.Ĭarbon Monoxide - Carbon monoxide is a colorless, odorless, highly toxic gas produced during the combustion process.Ĭarbon Dioxide - Carbon dioxide is formed as a result of the combustion of various hydrocarbon compounds that make up petroleum based fuels, including diesel. The WHO (World Health Organization) has classified diesel particulates as carcinogenic, meaning prolonged exposure may cause cancer. Such is the case in the combustion of fuel in a diesel engine, as nitrogen gas is a naturally occurring element in atmospheric air.ĭiesel Particulate Matter - Diesel particulate matter, often abbreviated DPM, refers to the emittance of soot following the combustion of diesel fuel. Nitrous oxides are produced when combustion occurs in the existence of nitrogen. In addition, NOx may worsen pre-existing medical conditions such as asthma and bronchitis. NOx emissions contribute to the development of acid rain and smog. These are not to be confused with nitrous oxide. ![]() Nitrous Oxides - Nitrous oxides, typically simplified as NOx, refers to the compounds nitrogen dioxide and nitric acid.
