Explain two thermodynamic methodologies of TDC determination in IC engines

based on a motoring in-cylinder pressure data.

Make a list of the important combustion parameters affected by absolute pressure referencing error, and discuss whether the referencing error is affected by

engine operating load. Write a performance or combustion parameter which is

not affected by absolute pressure referencing, and justify your answer.
