The engine mount is an important component of your car as it connects the engine to the chassis. Without this part, power from the engine cannot be smoothly transmitted to the ground without breaking the chassis into parts.
Let us discuss the
different types of mounts in detail:
Transmission
Mounts
They are usually made of a solid rubber shock-absorbing element laminated to a pair of steel base plates bolted to the gearbox and engine chassis. They offer an excellent effect of damping vibration and noise, but after a while they are prone to cracking and tearing, and also allow maximum movement under load. This leads to a decrease in power transmitted through the transmission from the engine to the rear wheels. For serial or slightly modified street engines, it would be nice to get these mounts, but it is advisable that you increase power with increasing power.
Metal Mounts
As the name implies, in the manufacture of rubber or polyurethane is not used – it is an all-metal mount. They can create a strong metal-metal compound, which means that they allow the greatest vibration and noise. This may sound like a drawback, but the amount of power transmitted to the wheels is maximum, as they bend slightly under load. It is advisable to be only for competition due to vibration and noise factors.
Hydro Mounts
These are fluid-filled bearings that allow them to absorb and dampen engine vibrations that would otherwise pass directly through a conventional monolithic rubber mount. But they are more expensive than those made of rubber, and tend to leak fluid and / or collapse after many years of use.
Electronic Mounts
Some imported cars of the latest model have electronically controlled “active” mounts, which can change the rigidity of the mount, suppressing harmonics at different engine speeds and loads. They can use a vacuum drive to change the stiffness of the mount, and some create their own oncoming push to compensate for engine vibrations at different speeds.
The engine mount is probably one of the most neglected parts of your car, so you should be very careful when checking this component, because over time it crashes and crashes. For example, if you notice an increase in metal noise and shaking under the hood, it may be time to check and replace the mounts. There are several other signs that warn you of a poor or defective mount – ask your mechanic how to monitor them.
