Burning Smell from Car When Accelerating: What’s the Cause? 

You can’t just brush off the issue if you notice a burning odor coming from your vehicle whenever you put your foot down on the accelerator. This burning smell is not coming from your child’s hockey equipment, and you need to treat it seriously in order to prevent more severe issues with your car.

Burning smell from car when accelerating is often related to the car overheating, but it might be coming from a variety of other components of your automobile.

Along with providing answers, this article also helps identify the many factors that contribute to the burning smell that comes from a moving vehicle during acceleration.

Why Burning Smell When Accelerating?

There are a lot of things that might cause your automobile to have a burning smell as you accelerate. It is essential that you become well-versed in all of these various explanations in order to correctly identify the culprit component.

As soon as you have narrowed down the list of potential reasons, you will be able to make informed decisions about whether or not to continue driving your car.

The burning smell from a car may take one of four distinct forms, and each form has a unique set of causes and potential solutions:

1. Smell of a Burning Rubber

Your car has numerous rubber components, and any heat access that leads to those rubber components poses a risk of burning the rubber components. If you start to notice a stench similar to burnt rubber coming from inside your vehicle, the issue is most likely connected to the clutch, the drive belt, an oil leak, or a coolant leak.

Clutch Problem: It’s possible that if you drive a car with a manual gearbox, you’ll become so pumped up that you’ll mash down really hard on the clutch when you engage it.

By applying an excessive amount of force to the clutch, you are pressing it harder on the other components of your car, which causes a significant amount of friction. Because of the degree of friction, the inside of the car generates an excessive amount of heat, and this heat has the potential to cause the rubber components that surround the clutch to melt or burn.

As a direct consequence of this, you can begin to detect an odor of burned rubber coming from the clutch.

If this is the issue you are having, the best piece of advice the Car Expert Group can give you is to consult with a professional who has experience operating vehicles with manual transmissions. They will be able to assist you in applying the appropriate amount of pressure to the clutch and ensure that you do not run into any additional issues.

Smell of a Melting Drive Belt: The smell of burning rubber might have been caused by a melting drive belt surrounding your engine. In the event that you are unaware, the engine is linked to many other components by means of belts of various varieties. This belt is in charge of conveying motion to other components and keeping them moving in order.

It is fairly usual for the belt to continue contacting a hot engine and cause it to melt if any of these components were trapped or jammed. As a direct consequence of this, you will detect “burning smell from car when accelerating.”

If your issue is occurring as a result of a drive belt that is melting, you will need to have your car fixed as quickly as possible by a qualified professional technician.

Coolant or Oil Leaks: If hot oil or hot coolant flowed into your car’s rubber components surrounding the radiator or engine sections, there is a good chance that a smell similar to that of burnt rubber would be there.

If your gasket is blown, there is a good chance that oil may seep out. It is the job of the gasket to ensure that the engine cylinders are hermetically sealed, therefore preventing hot oil from dripping onto the rubber components that are located nearby.

Likewise, coolant may seep into the rubber components of the radiator via any cracks that may be present.

No matter where the leak is coming from or what caused it, you need to get these cracks fixed by a qualified technician as soon as possible in order to prevent more serious complications with either your engine or your radiator.

2. Burning Plastic Smell

There are many different sorts of odors, one of which is a burning plastic smell. If the smell of burning coming from your car is more like the smell of burning plastic, the causes may be different.

The following is a list of the several factors that contribute to the smell of burning plastic:

Problem With the Heaters:  If you have determined that the many reasons that have been suggested for a burning smell in rubber are not to blame, then it is possible that the problem is associated with the heaters.

If you have been driving your car for a longer period of time and you began to notice this burning smell of plastic, there is a possibility that something got caught within the heating system and was burned.

In order to resolve this issue, you will need to clean the heaters and drain the fluids out of them. If you do not have the necessary technical or mechanical skills, you will need the assistance of a professional technician.

Problems With the Car’s Electrical System: The burning smell of plastic might also be caused by problems with the electrical system, which is another prevalent reason for the burning smell from car when accelerating. If for some way one of your electrical lines or connections were burnt, you would start to notice a smell of burning plastic.

Consultation with an experienced technician is the most effective course of action in this situation. This person will be able to assist you in locating the burned electrical wire connection and, if necessary, replacing the wire itself.

3. Burning Oil Smell

If the burning smell is more like burning oil, you should look into different causes than the ones mentioned above.

Here are some of the common causes of an oil-burning smell in your car:

Oil Change Issues: The instructions provided by the car manufacturer state that an oil change must be performed on every vehicle at the specified time and frequency.

If you did not change the oil in your vehicle at the recommended intervals, you would be driving your vehicle with oil that had a tainted or filthy appearance. Therefore, it is quite probable that you will start smelling the odor of burning oil emanating from your vehicle.

You are going to need to go ahead and do an emergency oil change as soon as possible in order to fix this problem.

Loose Oil Filters: The presence of loose oil filters is a second potential cause of an odor similar to that of burning oil.

In the event that the oil filter is not securely fastened, there is a significant risk that oil will seep into the surrounding components of your car.

In the event of heated oil, there is a very high probability that the oil will burn any component that is nearby, which will result in the smell of oil burning.

In order to remedy the problem, you need to check the oil filter and ensure that it is tightened to a point where there is no possibility of any oil leaking out of it.

It is imperative that you take note of the fact that you should never try to do any kind of maintenance on the oil filter until your vehicle has been allowed to cool down and there are no potential hazards or safety concerns.

Failed Oil Plug: In the same way as when the oil filter was loose, if the oil plug in your car has failed, there is a very high probability that the hot oil will leak and begin burning outside of the system, which will result in a highly strong odor of burning oil.

If this is the case, you will need to remove the damaged oil plug and replace it with a brand new one before ensuring that there is no longer any oil seepage.

Blown Gasket: If the gasket has failed or been blown out, much like the reason for the burning rubber smell, you will start to deal with the smell of burning oil.

The gasket is the component that is accountable for sealing the cylinders and ensuring that there is no escaping of hot oil from the engine’s internal components.

As soon as this gasket gives out, the oil may easily seep out, and you will begin to smell the burning of oil.

Unfortunately, replacing a blown head gasket is one of the most costly repairs.

4. Burning carpet smells

The smell of a burning carpet is another sort of odor that you could be experiencing. When there is an issue with the brakes, the vehicle will often give off a smell like this.

The situation in which you are most likely to experience the issue is when you are traveling down a steep slope while applying a lot of pressure to the brake pedal.

This issue necessitates a visit of a skilled technician who will assist you in determining whether or not your brakes are still in excellent condition and whether or not you have already damaged them by pushing on them excessively forcefully. If such is the case, you won’t be able to drive this car again until you get the complete braking system replaced.

The Bottom Line

 If you are driving your automobile and notice any weird smells while you are in the car, you should take it very seriously.

One of the most significant problems, which you should not overlook, is if you notice a burning smell from car when accelerating.

Before trying to drive your car for extended distances, you should always first see a qualified technician and give him an exact description of the issue. Only then should you attempt to drive your vehicle.

If you choose to ignore this problem, it may even cause the cost in the future to increase manifold. While the issue may in some circumstances be easily and quickly fixed, there are also circumstances in which you may be required to make significant repairs that cost you a lot of money.
