A gasoline engine operates on an Otto cycle and is running at 2000 RPM. At that speed, it has an inlet air mass flowrate of 0.085 kg/s at a pressure of 85 kPa and a temperature of 280 K. After combustion the temperature is 2000 K and the highest cycle pressure is 5 MPa. Find the compression ratio, the cycle efficiency, and the heat added during combustion.

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
