International strict guidelines imposed by the administrations require manufacturers to perform various technical modifications and develop new technologies to reduce and control emissions of exhaust gases. In this course the main technical solutions used by most manufacturers to reduce emissions from vehicles using gasoline as fuel will be studied. For this purpose the compounds derived from the combustion will be discussed in petrol. During focus primarily on systems reduction of hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx) and carbon dioxide (CO2).
The main objectives of this course are:
- Know the combustion aspects relating to emissions of gases produced in the same and its effects on the environment and people.
- Know the different antipollution regulations and particularities of each.
- Know and analyze changes and motor exo-endo-motor technology and are responsible for reducing exhaust emissions. Its structure, components and operation.
- To provide students with the ability to diagnose and repair systems involved in reducing exhaust emissions, as well as the skills to deal with customers, drivers or car owners.
- Provide examples of manufacturers that incorporate systems for reducing exhaust emissions and the peculiarities of each of its technologies.
