i'd like to know what are the various a.motive engine mounting systems available now and technical description

Question

The hydraulic engine mounting type has a specific fluid to damp/isolate the engine vibration. Would like to know the detail workings of it on how the design for the chambers within the system is decided. also the advantage/disadvantage of this system compared to the classis solid rubber damping used in engine mounting systems. Also appreciate the description on terminologies used in the system. thanks

Answer 1

In hydraulics (actually I think they're pneumatic), you can always develop leaks from excessive force. They are pretty sufficient at completely dampening the engine movement and vibration. There's not much to them except a sealed bladder and a spring. They're also very difficult to install. With rubber mounts, the rubber can dry-rot in about 10 years or less. Unless you pay a pretty price for the hydraulics/pneumatics, I'd stick with rubbers. Cheap parts always have problems.
