Engine mounting structure.

摘要

An engine mounting structure for mounting an automotive engine (1) on the body structure of an automotive vehicle, comprising the parallel combination of a main oscillatory system (35) adapted to damp vibrations produced by the engine (1) during medium-speed cruising of the vehicle and an auxiliary oscillatory system (34) adapted to cancel the vibrations to be transmitted through the main oscillatory system (35) under high-speed cruising conditions of the vehicle for reducing booming noises to be produced in the vehicle cabin under such conditions. The auxiliary oscillatory system (34) comprises at least one mass member (33) and at leasttwo resilient blocks (31) and (32) structurally intervening between the mass member (33) and the main oscillatory system (35).
