The invention discloses a left mount assembly for an automobile engine. The left mount assembly comprises a left mount and a left mount support, wherein the left mount comprises an automobile body connection frame, a bracket arm and a rubber bushing, the rubber bushing comprises an annular housing, a metal core, a first rubber and a second rubber, the first rubber comprises an annular part and a splayed part, and the inner walls of rubber portions dead against the upper left part and the upper right part of the metal core on the second rubber are zigzag; the automobile body connection frame comprises a left mount upper support, a left mount lower support and a left mount limit plate which are all sheet metal parts, and the bracket arm and the left mount support are cast parts, so that inflection points on the static stiffness curve of the mount in case of over-vibration of a transmission can be avoided; the second-order and the fourth-order excitations of the engine are avoided, thus resonance during a use process is avoided, so as to meet the modal requirements of the left mount support, and the carrying boundary requirements of the engine and the whole automobile; and the automobile body connection frame is a combined frame formed by welding sheet metal parts, and integrates an installation function for an air filter.
