When you have just started the engine to go out, or when you stop at a traffic light while driving, you may feel an unusual vibration coming from the engine area.
Is this vibration caused for some reason, or is it due to an engine malfunction that needs to be addressed? The engine is the heart of a car, and many people feel uneasy about the slightest thing.
In this article, we will discuss the causes and countermeasures for vibrations generated by a car’s engine.
What Are Some Possible Causes Of A Car Engine Vibration?
The following are possible causes of a car engine vibrating louder than usual.
The Engine Is Cold
This phenomenon is especially common during cold weather. The engine is cold and idling is unstable, resulting in the vibration. If you check the temperature gauge and the vibration gradually subsides as the engine warms up, there is no need to worry, as this is a common occurrence in all cars.
If necessary maintenance such as changing the engine oil and oil filter, deteriorating the air cleaner, plugs, and belts are not performed properly, problems may occur inside the engine, leading to knocking and other vibrations.
Dirt Inside The Engine
Dirt inevitably accumulates on engines that have been used for many years. If this dirt becomes severe, combustion in the engine may become unstable, causing vibration.
Malfunction Of Various Parts Related To The Engine
Problems with various engine-related parts, such as clogged air filters, deteriorated rubber parts (hoses and pipes), and malfunctioning fuel pumps (electric motors), can lead to abnormal engine vibration. As with dirt inside the engine, incomplete combustion of the engine can be the cause.
What Are The Countermeasures And Remedies For Each Cause Of Engine Vibration?
The following are countermeasures and remedies for the causes listed above.
Countermeasures Against Vibration Caused By An Overcooled Engine
There is no need to do anything in particular because it is not a malfunction. Due to environmental issues and the performance of recent cars, it is no longer necessary to warm up the engine as in the past. There is no need to worry, as the engine warms up as it runs and the vibration subsides.
Countermeasures Against Vibration Caused By Lack Of Maintenance
Make sure to perform the recommended maintenance such as changing the engine oil and filter, checking the plugs, etc. on a regular basis.
Countermeasures Against Vibration Caused By Dirt Inside The Engine
To a certain extent, internal engine contamination can be cleaned by using a cleaning gasoline additive or flushing the engine. If cleaning with cleaning gasoline additives or flushing does not improve the problem, the engine internals must be overhauled or replaced.
In either case, this should be done in accordance with the condition of the engine and should be discussed with a specialist well in advance.
Countermeasures Against Vibration Caused By Malfunctioning Of Various Engine-Related Parts
Replace old, deteriorated, or cracked parts with new ones. Fuel pumps and other parts are difficult to determine by yourself, so if there is a large vibration, take the engine to a repair shop for inspection.
Abnormal vibration of the engine may not be noticed until it worsens considerably. Once it gets worse, there will be no fundamental solution unless the cause is identified and addressed.
To avoid such a situation, it is important to perform routine maintenance to avoid problems as much as possible.
