Diesel Anti-Pollution

Course Details

The strict directives imposed by different international administrations are requiring manufacturers to develop very diverse and advanced technology in the area of controlling exhaust gas of diesel engines emissions. In this course we will analyse the compounds derived from combustion, which of these compounds are harmful to the environment and what technological solutions are proposed by manufacturers to mitigate each of them.

The main objectives of this course are:

• Discover the aspects related with combustion,the polluting agents that are generated and their effect on the environment.
• Learn about the different anti-pollution regulations and their particularities.
• Discover, diagnose and repair the components that comprise part of the systems: such as exhaust gas recirculation, two way catalytic converter, selective catalytic reduction (SCR), FAP or DPF particulate filters, etc.
• Teach the student how to handle these issues with techniques for diagnosing and repairing anti-pollution systems, as well as clients, drivers and car owners.
