The utility model discloses an automatic tensioner and an engine with the same, the automatic tensioner comprises a connecting assembly, a tensioning wheel and a tensioning arm assembly, and the connecting assembly is used for being installed with an engine body of the engine; the tensioning wheel is used for tensioning the belt; one end of the tensioning arm assembly is connected to the connecting assembly in a swinging mode, the tensioning wheel is installed at the other end of the tensioning arm assembly in a rotatable mode, and the length of the tensioning arm assembly is adjustable so that the belt can be kept in a tensioned state. An elastic mechanism in the connecting assembly enables the tensioning arm assembly to incline in the preset direction. The tensioning arm assembly drivesthe tensioning wheel to tension the belt; belt producing plastic elongation, when the elastic mechanism cannot drive the tensioning arm assembly and the tensioning wheel to tension the belt; the length of the tensioning arm a
