The term knocking may be familiar to four-wheeled vehicle drivers. In general, knocking is the term used when a sound like knocking appears on the engine. If you drive a car that makes noise and leave it alone it can have a bad impact on the engine components. Apart from that, the sound is also quite annoying when the car is running.
Knocking doesn't just happen, There are several things that cause knocking sounds from inside the engine. This cause is also not from the way you drive, but rather incorrect car maintenance. Vehicles need maintenance so that the components that make them up can work optimally. The oil needs to be changed and several other components also need to be cleaned.
The cause of knocking in the engine is due to several things that are considered trivial. The following are several causes of engine knocking as reported by Suzuki Indonesia.
Use of Low Octane Fuel
Each vehicle has a recommended fuel type. You can find out what type of fuel is best for your vehicle's engine from the gas tank cap. Vehicles in Indonesia are usually advised to use high octane fuel 90 to the top, for example, Pertamax. You may have used low octane fuel to save more money.
Money can be saved at the start of using the vehicle, However, if knocking is a problem that is starting to appear and is ongoing, expenditure actually increases. The car may need to go back and forth to the repair shop to be serviced and repaired. Not to mention if one of the components is damaged, then you have to replace it with a new one. Each car engine has a different compression ratio.
Example of a compression engine 10:1 then it needs octane fuel 92. When you use low octane fuel, This will cause the temperature and compression in the combustion chamber to increase. The octane value serves to assess its ability to withstand pressure so that excessive explosions do not occur in the combustion chamber. The way to overcome this is that you have to use fuel according to the recommended octane from the start.
Amount of Carbon Deposits in the Combustion Chamber
Knocking is a problem that occurs due to incorrect use of fuel and is closely related to the appearance of carbon deposits. Every burning that takes place will create residue or deposits. This deposit will settle in the combustion chamber, If it accumulates it will reduce the volume of the combustion chamber. Engine compression will also increase even though fuel with the appropriate octane is used, it will still cause knocking.
Carbon deposits will also work as a heat source, so that when the fuel is mixed with air, it will burn itself more quickly. Even though at that time the spark plug had not yet sparked a fire. When this carbon deposition problem is not immediately overcome, It's not just about knocking that appears. The engine also heats up more quickly until it overheats. The way to overcome this is to clean the combustion chamber regularly.
Especially if you just bought a used car and don't know what fuel was used before. So it's safer before changing to the right fuel, clean the baking area first.
Improper Use of Spark Plugs
The role of spark plugs in a vehicle is very large. Spark plugs not only spark fire but also control the internal environment of the engine. So the spark plug will work in precise conditions. When using spark plugs incorrectly, for example, you want to save costs that are actually not much. Spark plugs that do not comply with the manufacturer's recommendations will produce a spark that is too small.
Sparks that are not standard will result in an incomplete combustion process. Carbon residue will form more quickly so it can stick to the walls of the combustion chamber and valve. If this happens, it would be better for you to replace the spark plugs according to the manufacturer's recommendations or a standard type. You should replace the spark plugs according to the manufacturer's recommendations so that ignition can run more perfectly.
Knocking is a problem with vehicles that should not be taken lightly. When the knocking sound first appears, It's best to immediately go to an official repair shop. The source of the knocking will be immediately checked and can be repaired.
