As a Noun: 1. The small rubber and metal parts of a vehicle that attach the engine to the steel frame of the vehicle and reduce excessive engine vibration. English = engine mounting. Note: 1. There appears to be no commonly used Auslan sign for ENGINE MOUNTING for most signers (but some signers represent this visually using these depicting signs, once they have established the topic). This sign is a combination of the Auslan sign ENGINE followed by both hands depicting a hold action with a slight upwards motion. Source of this recommended sign: Victorian College for the Deaf.
