The invention discloses a left suspension assembly suitable for an automobile engine. The left suspension assembly comprises a left suspension and a left suspension support; the left suspension comprises an automobile body connecting frame, a supporting arm and a rubber bush; the rubber bush comprises an annular shell, a metal core, first rubber and second rubber; the first rubber comprises an annular portion and a splayed portion, and the inner walls of rubber portions, right facing the upper left portion and the upper right portion of the metal core, of the second rubber are in sawtooth shapes; and the automobile body connecting frame comprises a left suspension upper cover, a left suspension front support, a left suspension lower support and an L-shaped support which are sheet metal parts. The supporting arm and the left suspension support are castings, and the phenomenon that when vibration of a transmission is too large, an inflection point occurs in a suspension static rigidity curve can be avoided; two-stage motivation and four-stage motivation of the engine can be avoided, and therefore resonance in the using process can be avoided to meet the modality requirement of the left suspension support and the carrying boundary requirement of the engine and a whole automobile; and the automobile body connecting frame is a sheet metal part welding combined frame, and an air filter mounting function is integrated.
