The invention provides an engine with a logarithmic spiral invisible scavenging duct replacing a regular scavenging duct. According to the engine with the logarithmic spiral invisible scavenging duct replacing the regular scavenging duct, the regular slotting scavenging duct is revolutionarily removed from the inner wall, making contact with a piston, of a cylinder body of an internal combustion engine, so that the condition that a gap between the piston and the slotting scavenging duct of the cylinder body is adulterated and mixed with fresh charge and waste gas is avoided; and an invisible air duct of the engine with the logarithmic spiral invisible scavenging duct replacing the regular scavenging duct is a logarithmic spiral, the characteristic that the pressure angles are equal everywhere is achieved, air-resistance adulterating and mixing are reduced, the machining working procedure is simplified, and adulterating and mixing of the fresh charge and the waste gas are reduced. A bent air duct (534) is form
