- help to fill this table correctly in diesel cycle thank you so much for your helpIn actual 4 stroke engine cycle, combustion chamber pressure at the end of exhauststroke is greater than the atmospheric pressure and the pressure of the intake port onaverage is less than the atmospheric pressure. In theory, early opening of the intakevalve before the TDC should not result with fresh air getting inside the combustionchamber. However in actual applications,intake valve is opened 20 ~ 40 ᵒ CA beforethe TDC (Intake valve opening advance), inorder to increase the fresh air transfer intothe combustion chamber. Explain howintake valve opening advance increasesfresh air transfer into the combustionchamber.Pls. answer thank you! A running at 400 rpm has a specific speed of 60 rpm and head available is 41 m.
