Aftertreatment Modelling for Diesel and Gasoline Engines
In this project you will be calibrating a detailed compression ignition & spark ignition + explicit engine model by observing the effects of engine operating parameters on emissions and the conversion efficiencies of catalysts, such as TWC [Three Way Cat Conn] and DOC-DPF-SCR with urea injector, on different pollutants.

Benefits of this Project
In this project you will be calibrating a detailed compression ignition & spark ignition + explicit engine model by observing the effects of engine operating parameters on emissions and the conversion efficiencies of catalysts, such as TWC [Three Way Cat Conn] and DOC-DPF-SCR with urea injector, on different pollutants.
What will you do in this project?
Step 1 - Parameterization of an explicit SI engine + TWC model with inbuilt GPF [ Gasoline Particulate Filter]
Step 2 - Parameterization of an explicit CI engine + DOC [Diesel Oxidation Catalyst] - DPF [ Diesel Particulate Filter] - SCR [Selective Catalytic Reduction] with Urea Injector
Step 3 - GT-POST TWC Light-off temperature analysis / Lambda Monitor / TWC Conversion efficiency of different pollutants.
Step 4 - GT-POST DOC Monitor / Soot Retained Analysis / SCR Monitor
You will do the following in this project :
- Choose a Non-predictive explicit engine model with an EATS attached to it.
- Tuning the appropriate geometrical catalyst calibration parameters in different subsystems such as TWC for Gasoline & DOC-DPF-SCR for Diesel.
- Set up two different case setups for applications with/without an external EGR assembly and run it for rated and intermediate speeds and observe the performance vs emission trade-off.
- Post process the results in GT-POST to analyse the different effect of engine operating variables on emissions.

Pre-requisites
Work with Multiple Tools
Thermodynamic analysis of a tractor engine
In this project, you will be making use of the existing detailed Engine + Aftertreatment models in GT-POWER to understand the chemistry and the reaction mechanisms that goes behind modelling catalysts for a TWC [Three way catalytic converter]. You will also study the effect of light off temperature vs Conversion efficiency of pollutants for Spark ignition engines and the effect of catalyst temperature and Urea injection of a DOC [Diesel Oxidation catalyst] - DPF [ Diesel Particulate filer] - SCR [ Selective Catalytic Reduction] on Soot and NOx emissions.
