The Importance Of Working With The Right Mechanic

The engine comprises different components, and it will make low-toned noises as it starts. But, if you begin to hear sounds that are out of the ordinary, consider seeking mechanical services. Knocking noises are common in many vehicles and will mostly arise when the fuel doesn't burn evenly in your engine. Here's a more detailed look at other things that could lead to problematic noises. 

Excessive Oxygen Levels In The Fuel

If you have an efficient engine, the mixture of air and fuel will burn in a single detonation. However, when the air and fuel mixture has too much oxygen, you'll hear several detonations producing knocking sounds. This happens because there isn't enough fuel in the mixture, so it burns faster. On the first sign of such noise, visit an auto repair expert for diagnosis and repair. If you continue driving in this state, your vehicle pistons can fail.

Your Engine Rod Bearings Are Problematic

As the engine pistons move, so does the crankshaft to create electric energy transmitted to the wheels. Note that rod bearings are responsible for such movements. That being the case, if they wear out or fall out of alignment, they will produce sounds while moving along the crankshaft. If this is the noise source, your technician can address it by changing the rod bearing.

Substandard Fuel Quality

If you're using low-quality fuel (low octane rating), you should expect your vehicle to produce knocking sounds. The problem with using such fuel is that it will result in premature combustion. When this happens, you'll notice knocking sounds while accelerating. If this problem arises after refilling your fuel, consider adding an octane booster instead of changing the fuel.

A Malfunctioned Knock Sensor System

In some cases, the knocking sounds from the engine can arise due to a faulty knock sensor. This sensor detects issues and sends information to your vehicle's computer to adjust the air to fuel ratio. A faulty sensor will cause the engine to make the wrong adjustments, leading to continuous sounds. An experienced auto mechanic can diagnose whether you have a faulty sensor and make a replacement if necessary.

When your vehicle produces knocking sounds, it could indicate any of the above-mentioned issues. That said, other circumstances could contribute to the strange noises, and taking quick action to address them will ensure a great driving experience. An auto expert will also rectify the problem to ensure you don't end up replacing the entire engine.
