    In pressure vs Crank angle graph of my simulation result:

    ” Pressure drops from 12 bar to 1 bar directly (within 1 degree crank angle duration) in exhaust side of the graph ”

    Can any one knows the reason for that problem?

    Thank you in advance

    My Question is that “ How can i enter these different valve lift in simulation model ?“

    I have 4 valves (2 inlet valves and 2 outlet valves) for each cylinder in Gasoline Engine:

    2 Inlet valves have
    • 7 mm lift for first inlet valve
    • 10,5 mm lift for second inlet valve

    2 outlet valves have
    • 9 mm lift for first outlet valve
    • 10 mm lift for second outlet valve

    Hey Guys!!

    Could somebody tell me about the firing order of the cylinders in given 4 cylinder CI Engine model?

    I have not found the information related to firing order.

    what is the firing order in given 4 cylinder CI Engine model?

    Thank you in advance
