In my diploma thesis titled »Analysis of the emissions of diesel engines«, I tried to get close to today's reader issues relating to environmental pollution, mainly due to diesel exhaust, by bringing the industry in all its forms.
Traffic is the largest polluter of the environment, because the exhaust fumes of vehicles contain an extensive set of harmful substances (hydrocarbons HC, carbon monoxide CO, nitrogen oxides NOx, sulfur oxides, particulate matter, etc.). The purpose of the European and American standards is regulating emissions, editing different categories of vehicles and equipment. It also regulates the provision of tolerance limit for harmful emissions on market. My thesis includes an extensive definition of the aforementioned standards and interesting comparisons of harmful emissions in each category. Despite the fact that the emission regulations it’s very structured and well staged, still in real driving, due to many factors present, comes a deviation exceeding the standards. Because of that and also because of the hard way of achievement of the emission regulations, it is necessary to find a solution. The complexed human mind, along with advances in technology and the relevant financing, has found many different ways of resolving discrepancies, including a cheat. But the cheat can not and should not be a measure to tackle the issues mentioned. It is very important how much and how it is still possible to improve technology related to the reduction of harmful substances, so my entire fourth chapter, with reviews of the measures to reduce emissions from diesel engine, is dedicated to that.
I could not agree more with the words of Mr. Elon Musk, founder of the company Tesla Motors, which said: “I think the time has come to move on to a new generation of energy” [37].
