Exhaust gases aftertreatment

Duration: 1 working day

Price: 145 €

* Accommodation, breakfast, lunch, scripts and worksheets are included in the training price.

What have you not known until now, which will
advance your operation?

Do you know how does the low pressure exhaust gases recirculation system (which become standard equipment in addition to known high pressure EGR) works? How DOC or SCR catalytic converter works, and how you can check one? Which systems, and which components can affect operation of diesel particulate filter system operation? When is appropriate to perform regeneration, when cleaning and when replacement of DPF? How does the DPF system with additive works, and what can cause malfunctions? How to test wide band oxygen sensor or NOx sensor? When regeneration will start, and when it will be forced to stop? Why we have DTC, and is the forced regeneration always the answer?

Why is this important?

With stricter emission standards, modern vehicles with internal combustion engines, are forced to carry with them real chemical plant, which should reduce emission of harmful gases, air pollutants and particles. System by itself, have become very complex, components expensive and diagnostics complicated and demanding.

What is the training
like?

Description of components and systems involved in exhaust gas aftertreatman. Diagnostics of systems and components, analysis of parameters and testing.

How will you become better in your work
after these training sessions?

With increased complexity of exhaust gases aftertreatmant systems, diagnostics is more demanding and more time consuming. Good understanding of system, enables faster and more accurate diagnostics, saving time and preventing unnecessary replacement of expensive component When do you have to induce forced regeneration, when do you have to replace DPF, and what was the cause of malfunction.
