Following this, many researchers have been trying to find ways to make 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 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. History: Locomotive Industry Diesel engines use in internal combustion to produce their effects, hardware invented by Rudolf Diesel. Diesel patented his invention in 1892. Originally, he had planned to use coal for the engine’s fuel, but in modern diesel lawful oil, which is relatively affordable.

There are several benefits for individuals who decide to use these types of engines. First, the engine does not need a significant amount of water, it warms up rather quickly, and it does a very good job of efficiently converting heat energy into work. They are also much smaller than steam units, and thus help to save space for companies that wish to use them (Columbia Encyclopedia). Taking a closer look at the effects of diesel engines can increase overall understanding of their benefits.

Therefore, a closer look at diesel engines in locomotives will be presented in this analysis (Zhao, 2006) Steam and diesel locomotives have very different technologies and these huge differences have caused wide differences in both production and marketing for locomotive companies. Steam locomotives have remained customized and purpose-built (Yin, X., Schafer, et al. 2003). On the other hand, diesel engines are much more adaptable, allowing for the form and of fewer desigfor and ideas.
