The invention discloses a two-stroke engine using a left box body with a separating wall containing multiple through holes to assist in scavenging. The two-stroke engine has the beneficial effects that the left box body is provide with the separating wall containing the multiple through holes, and thus manufacturing difficulty can be greatly and revolutionarily lowered; due to the facts that die-casting of the demolding separating wall can be performed on the box body of the plain structure easily, and die-casting of the demolding separating wall cannot be achieved easily on a complex piston cylinder block at the deep place, three sections of arc lines are arranged at the upper side of the separating wall, the arc line located in the middle of the three sections of arc lines is a circular arc line (527), and the arc lines located at the two sides of the three sections of arc lines comprise a logarithmic spiral section (525) and a cubic curve section (526); the cross section of the piston is the cubic curve se
