Many engine manufactures have had to explore techniques in order to update their diesel engines and keep them within the requirements of automotive emissions regulations. There is certainly a worry about decreased performance of diesel engines when they are more "clean running." When emission regulations were not required, the diesel engine was a very efficient tool, able to run and maintain itself with its large use of heat.


Following this, many researchers have been trying to find ways to make the diesel engines run as powerfully as they have in the past. Some ideas that have been considered so far are new modes of combustion, exhaust gas recirculation - EGR, after treatment and use of hydrogen produced by fuel reforming as a combustion improver. For diesel engines, these techniques are mainly focused on the reduction of both nitrogen oxides (NOx) and particulate matter (PM) emissions. EGR has been extensively used as a successful method of reducing NOx emissions, but it results in a well-reported increase in the fuel consumption and increased smoke and PM emissions, as the air admitted into the engine is partially substituted by exhaust gases. In this paper, a closer look will be taken at more effective diesel engines, considering the history of diesel engines up to issues affecting diesel engines in the present time.
Diesel engines use internal-combustion to produce their effects, and were invented by Rudolf Diesel. Diesel patented his invention in 1892. ...
