What is the function of the left and right engine mounts?

The functions of the left and right engine mounts are as follows: Supporting role: The most basic function of the mounting system is to support the powertrain. When designing the mounts, it is essential to ensure that the vehicle's powertrain is positioned correctly and that the entire mounting system has a sufficient service life. Limiting role: During transient conditions such as engine start-up, shutdown, vehicle acceleration and deceleration, as well as various interference forces (e.g., road bumps), the mounts should effectively limit the maximum displacement of the powertrain to prevent collisions with surrounding components and ensure proper powertrain operation. Vibration isolation role: As the connecting component between the chassis and the engine, the mounts must not only prevent engine vibrations from being transmitted to the vehicle body but also mitigate the impact of uneven road excitation on the powertrain.
I've been driving for ten years, and the engine mounts are located on both sides, just like shock absorbers, absorbing engine vibrations to prevent the car from shaking all over. Normally when starting the car or accelerating, the engine vibrates, and the mounts, made of rubber, cushion these vibrations. If they fail, the car becomes extremely noisy with a rumbling sound, and the steering wheel may even shake. Over time, this can damage other components like the wheels or suspension system. I remember during a maintenance check last year, cracks were found in the mounts. After replacing them promptly, the car became much quieter, and I avoided spending extra money on major repairs. It's recommended to check the mounts every six months or every 10,000 kilometers by pressing them to feel their firmness and check for cracks, preventing aging from affecting the overall driving experience. In short, though a small component, it plays a significant role in smoothness and comfort.
