  1. Petrol engine and diesel engine Cycle ( Otto and diesel) comparison www.bookspar.com | Website for Students | VTU NOTES | QUESTION PAPERS

  2. Otto cycle ( theoretical) • Suction stroke • Compression stroke • Working stroke • Exhaust stroke www.bookspar.com | Website for Students | VTU NOTES | QUESTION PAPERS

  3. Suction stroke • Stroke is represented by the line horizontal line AB. www.bookspar.com | Website for Students | VTU NOTES | QUESTION PAPERS

  4. Compression stroke • Reversible adiabatic • Represented by curve BC. • Constant volume combustion process represented by vertical line CD. www.bookspar.com | Website for Students | VTU NOTES | QUESTION PAPERS

  5. Working stroke • Process is represented by the line DE. (reversible adiabatic process) • Exhaust opens and drop in pressure is represented by EB. www.bookspar.com | Website for Students | VTU NOTES | QUESTION PAPERS

  6. Exhaust stroke • Process is represented by a horizontal line BA. www.bookspar.com | Website for Students | VTU NOTES | QUESTION PAPERS

  7. Diesel cycle www.bookspar.com | Website for Students | VTU NOTES | QUESTION PAPERS

  8. Suction stroke • This process is represented by the horizontal line AB. www.bookspar.com | Website for Students | VTU NOTES | QUESTION PAPERS

  9. Compression stroke • Adiabatic process represented by the line BC. www.bookspar.com | Website for Students | VTU NOTES | QUESTION PAPERS

  10. Power stroke • Constant pressure expansion due to combustion of fuel is represented by CD. • Expansion of burnt gases represented by the curve DE. www.bookspar.com | Website for Students | VTU NOTES | QUESTION PAPERS

  11. Exhaust stroke • Exhaust port opens at end of previous stroke represented by curve EB. • Exhaust gases expelled out represented by the curve BA. www.bookspar.com | Website for Students | VTU NOTES | QUESTION PAPERS
