Three-dimensional modeling and exergy analysis in Combustion Chambers of an indirect injection diesel engine

- We carried out exergy analyses in pre and main chambers of an IDI diesel engine by three dimensional model.
- At 50% and full load cases 56% and 77% of total irreversibility are related to combustion in main chamber, respectively.
- When load increases from part to full load, the amount of exergy flow in throat increases to 56%.
- At part and full load cases, 65.7% and 55% of total heat loss exergy concern to heat loss in main chamber, respectively.
