Exhaust emission<\/p>\n
Challenges are what drives us.
\n\u00a0
\nOne of the great challenges facing the diesel engine manufacturers is the implementation of the future exhaust emission laws. Regulations for the systematic reduction of pollutant concentrations in the exhaust gases of diesel engines have been introduced in Europe and the USA since 1996.
\n\u00a0
\nAir contaminating substances caused by the combustion of fossil fuels are responsible for a number of negative influences on the environment and health, for example acid rain, smog and greenhouse gases which are seen in connection with globalwarming and respiratory complaints.
\n\u00a0
\nThe exhaust gases of diesel engines consist primarily of NOx, CO, HC, particle, CO2\u00a0and water
\n\u00a0
\nNOx:\u00a0Nitric oxide: A combination of nitrogen monoxide NO and nitrogen dioxide NO2\u00a0which contributes to smog and is a major factor in the development of acid rain when fuels with a high sulphur content are used.
\n\u00a0
\nCO:\u00a0Carbon monoxide: Is tasteless, odourless and toxic and is produced at high combustion temperatures or when too little oxygen is available in the combustion.
\n\u00a0
\nHC:\u00a0Hydrocarbons: These are the result of incomplete combustion and occur as many different pollutant varieties.\u00a0
\n\u00a0
\nPM:\u00a0The particle emission is spart of the complex diesel emissions. The main components are metal attrition products from the engine, carbon (soot) and hydrocarbons from the fuel and lubricating oil as well as watery sulphuric acid produced from the sulphur in the fuel. Metallic particles are also present in traces.
\nCO2:\u00a0Carbon dioxide: Familiar as greenhouse gas. The CO2\u00a0emission values of diesel engines are below those of petrol engines.
\n\u00a0
\nThe topic of exhaust emission limiting and reduction is extremely complex. Increasingly profound measures in the engine design, the injection, combustion and charging technology and the use of exhaust post-processing are necessary to keep the permissible emission limits.
\n\u00a0
\nAfter successfully implementing the first steps of the European and US emission reduction we have now turned our attention to the future European and US exhaust stage (EU Stufe IV, EPA Tier 4final). This is the greatest challenge to the engine manufacturers so far and will lead to the application of further technology modules.
\n\u00a0
\nThe basic philosophy of DEUTZ: We will only introduce technical modifications to the engine design and the complexity where this is necessary for safe implementation of the legal provisions or customer requirements. In the meantime we will keep our sights set firmly on the economy and reliability of the diesel engine<\/p>","protected":false},"excerpt":{"rendered":"
