Notes on the Exhaust and Intake Process in Engines Exhaust Process: 1. Exhaust Initiation: o Begins 40 to 60° before Bottom Center (BC). o Burned cylinder gases are discharged due to the pressure difference between the cylinder and the exhaust system. 2. Phases of Exhaust Process: o Blowdown Phase: ▪ Up to BC, gases escape due to pressure differences. o Displacement Phase: ▪ After BC, the piston movement toward Top Center (TC) scavenges the cylinder. 3. Exhaust Valve Timing: o Closes approximately 15° after TC. Intake Process: 1. Valve Overlap: o Both exhaust and intake valves remain open for a period. o During overlap, backflow of gases (exhaust into the cylinder and cylinder gases into the intake) occurs when Pi/Pe
