WHAT IS AN ENGINE MOUNT (PILLOW) AND WHAT IS IT FOR?

During the operation of the motor, vibrations are formed in it. If you fix it on a support tightly, then there will be a terrible hum in the cabin, regardless of whether the car is standing or driving on an ideal road.

Depending on the design of the car chassis, the engine and gearbox are fixed to:

• Frame;
• Subframes;
• The body.

The engine mount primarily performs a damping function. In addition to the fact that the pillow protects against the spread of vibrations from the engine and gearbox throughout the body, it prevents the engine and transmission from swaying while the car is moving along bumps.

NUMBER AND LOCATION OF ENGINE MOUNTS

The number of pillows depends on the brand of the engine, namely, on its weight and power (this factor affects the strength of vibrations). Also, depending on the type of bodywork or chassis design, the number of engine mounts varies. Another factor on which the number of these parts depends is the location of the internal combustion engine in the compartment.

Most often there are three-point mounts. Less often - four-point. These elements are not so easy to see - for this you need to look under the car (if it does not have crankcase protection). Under the hood, you can see only the top cushion (and even then not in all cars).

It is also worth noting that for the gearbox and for the motor, its own dampers are used.

THE DEVICE AND PRINCIPLE OF OPERATION OF VARIOUS TYPES OF ENGINE MOUNTINGS

Although the main purpose of pillows is to dampen motor vibrations, today there are several varieties of them. They all cope with their function. They differ only in design, principle of operation and cost.

There are two types of supports: 

• Rubber-metal;
• Hydro support.

Each of them works on its own principle. Some work to compress rubber, others to twist. The second category is considered the most innovative among this type of damper parts.

RUBBER METAL

Such parts are also called simply rubber. Their design is the simplest - a rubber insert with a metal eye in the center, into which a mounting pin is inserted, is placed in a metal support (attached to the body)

Most often, this type of support is used in older engines. Sometimes there are modifications not with rubber, but with a polyurethane insert. Such varieties of supports are more hardy.

HYDRO BEARINGS:

This kind of dampers works on the principle of a shock absorber in the suspension. They have a more complex design. In addition to rubber seals, they also have a cavity filled with air or damping fluid. The most common option is two-chamber supports. In them, both planes are connected to each other by a thin channel through which, under load, the fluid moves.

The types of hydrosupport include:

Mechanical pillows.

They are made for each modification of the motor separately. The force of vibrations, the mass of the motor and its dimensions are taken into account.Electronic pylons. In addition to the presence of working chambers, a solenoid valve is included in the device of the part, which regulates the rigidity of the support. The damper operation is automatically adjusted by commands from the computer.

Dynamic supports. In such parts, metal particles are part of the working fluid. Due to the influence of a magnetic field, the structure of the liquid in the pillow changes (it changes the degree of viscosity). Naturally, the cost of rubber supports is much lower than hydraulic counterparts.

DIAGNOSTICS OF PILLOWS OF THE ENGINE

In the case of rubber-metal pads, the diagnosis is as simple as possible - it is enough to conduct a visual inspection for the presence of delamination or rupture of the rubber part. If a type of hydraulic support is installed in the machine, then a visual inspection is unlikely to help.

The hydraulic support can be checked as follows. First, open the hood and start the engine. The first speed starts, drive a couple of meters and stop. We engage reverse gear, drive the same distance. We stop the engine.

During the procedure, unnatural knocks and clicks should not be heard from the engine compartment. If there is still extraneous noise, this indicates a malfunction of one of the supports (or maybe several). It also does not hurt to drive along the highway at high speed (permissible by law). If jerking is felt when switching speeds, then the problem is definitely with the supports. Hydraulic pads can also be checked for fluid leaks. This can be done with a visual inspection.

SIGNS OF WEAR ON ENGINE MOUNTINGS

This is what causes engine mount failures:

The engine vibrates strongly at idle (it is also important to make sure that the ignition and fuel system are working, and the valves are correctly adjusted); When driving (especially during gear changes), knocks are heard and jerks are felt, as if the motor is swinging; When the engine starts, knocks from under the hood are clearly audible; Difficulty switching gears.If the machine is equipped with hydraulic supports, the motorist can determine their malfunction in case of loss of dynamism of the vehicle.
