CCNY engineering intern design challenge: Summer 2023 Justify ALL equations/tables/charts/data used and show calculations Midterm: DUE
THIS WED AT 11PM ON BB: July 26th 2 for any decisions made including AF ratios determinations. Cycle 1.5 FIG 1 Given: DAWN- For gasoline,
the heat of combustion is q. = 44,510 kJ/kg Cp = 1.007 kJ/kg and the specific heat ratio = 1.4 Surface heat flux, MW/m2 0.5 If one ... 

Superchargers, although parasitic, are being used with a small displacement engines. This design philosophy is in support of lean burn, high compression, and increased BSFC. A new strategy to keep the internal combustion engine relevant vs EVs. Choose a current NA auto engine different from your platform engine. Use Fig 1 to corroborate its ignition timing and calculate its BMEP. Now consider that another NA auto engine with a displacement volume of 1.6 L is to be increased in pressure to 130 kPa from Po = 101 kPa and To = 298 K using a roots supercharger. An intercooler will be used to cool the compressed air entering the engine to Ti = 320 K. As a baseline reference, the engine is to use gasoline with stoichiometric combustion in some mid-range RPM (show the combustion reaction). The engine thermal efficiency ?t = 0.35. The supercharger performance map is given. The supercharger is mechanically coupled to the engine and rotates at twice the engine speed. Make valid assumptions and choose wisely. Professional documentation! Now you know from your CCNY degree that a tuned intake manifold will have locally higher pressures when the intake valve is open, increasing the intake charge density;
