    Scavenging is the process of escape of fresh charge without getting utilized.
    For uniflow and loop scavenging, I hope following link will help you:

    I thought scavenging means pushing out the exhaust gases, not fresh charge from the engine cylinder.

    Yes, it is pushing out of exhaust gases by the fresh air that enters the cylinder.
    Since intake and exhaust process takes place at the same time, some of the fresh charge also escapes with the exhaust gases. Thus, it is the reason for the low efficiency of 2-stroke engines.

    Do you mean the difference between intake and exhaust process?

    no.... i am talking about simple definitions of these two..!!

    LOOP SCAVENGING is that process in which the charge passes over the piston crown and rises to form a loop within cylinder.

    UNIFLOW SCAVENGING is that process in which charge air passes straight up through the length of cylinder.
