Week 11: Project 2 - Emission characterization on a CAT3410 engine

Aim: Project 2 - Emission characterization on a CAT3410 engine

Objective

Your job is to run simulations with both these pistons and characterize the emissions (Soot, Nox, and UHC)

• Create cut-plan animations showing Soot, Nox, and UHC and compare them between the omega and the open-w pistons.
  • Upload animations on Youtube and provide the Youtube link for animations in your report.

• Compare the IMEP and Power values graphically

Introduction

The Deisel Engine is an IC Engine in which the ignition of the fuel is caused by the ignition of the air at the elevated temperature of the air in the cylinder due to the mechanical compression, thus the diesel engine is a so-called compression-ignition engine. The air temperature in the cylinder is elevated to such a high degree that atomized diesel fuel injected into the combustion chamber ignites simultaneously.

Application

The application of diesel engines includes

• Passenger cars
• Commercial vehicles and lorries
• Railroad rolling stock
• Watercraft
• Aviation
• Non-road diesel engines
• Stationary diesel engines

Case-setup

Make engine sector surface: The Converge provides a convenient option to simulate the sector surface engine, as the whole diesel engine will be tedious to simulate and time-consuming, and moreover, the results from the sector surface are reliable. In this challenge, the diesel engine sector surface is produced by using two-piston profiles which are omega piston and, open w piston.

The surface generated by the Converge are shown below.
