DESCRIPTION

Semi-active mounting(it can also be called 'Electronic Controlled Mounting(ECM)') , unlike hydraulic mountings before, is a controllable hydraulic mounting which gives a high damping value in driving and also reduce viblation with a low damping value and a spring coefficient at idle.

This system is composed of a control module, solenoid valve and a diaphragm for ON/OFF in it.

At idle, the control module receives a RPM signal and give it to the solenoid valve. As the valve opens or closes, vacuum pressure in the intake system goes to the diaphragm for opening the orifice. By opening the orifice, the mounting has a low damping value and a low spring coefficient for reducing viblation.
