Q.1 Diesel pressure data with 0.1CA resolution is provided. Perform the following activities: 1. Perform pressure pegging on fired pressure (Use 5CA half width - with 0.1CA data, that means 50 pressure points before and 50 after IVC) Provide the Apref value 2. Check corrected pressure data quality (using log p - log V) using the segment from 285 to 325CA; Provide a plot of log p vs log V, with the segment of compression stroke used for quality check highlighted and the polytropic coefficient value Provide the plot on a separate "chart sheet" of Excel 3. Calculate the gross, pumping and net values of IMEP (bar) using W = PavgdV and provide the values 4. Calculate the mean cylinder temperature (Tcyl,mean) in C from IVC to EVO; Provide the maximum value of Tcyl,mean in C and a plot of Tcyl,mean [C] vs crank angle from IVC to EVO using pV = mRT cyl,mean Provide the plot on a separate "chart sheet" of Excel Engine specs: Bore: 75 mm Stroke, 88 mm Connecting rod length: 155 mm CR: 18.2:1 IVC: 205CA EVO: 510CA Reference Conditions: Manifold Air Pressure (MAP/Ppeg): 1.69 bar at IVC 55C at IVC Manifold Air Temperature (MAT): Perform all calculations on 0.1CA data Report all final answers up to 3 decimal places or 3 significant digits if value < 1
