For a small device, spark plugs can cause bigger problems like misfiring, engine knocking, hard starting, and poor fuel consumption. As this tiny device’s health is integral to your car’s well-being, you must take care of this humble powerhouse.
In this blog, we will understand the importance of spark plugs and see why they are considered an integral part of your car. So join us as we explore these little contraptions and see how mechanic shops can help.
What Are Spark Plugs?
Spark plugs are electrical devices that deliver electricity to ignite the air-fuel mixture in your car engine’s cylinder. These are an essential part of internal combustion engines. The best spark plugs create sparks, igniting the fuel and, in turn, running the engine.
Where Are they Located?
They are usually located at the top of the cylinder head in an engine, with each cylinder at least having one spark plug. However, the location may vary depending on the type of engine.
For example, in a four-cylinder engine, the plugs are in a row on the upper side of the engine head. In the case of a six-cylinder engine, the spark plugs are located on the side or the top of the engine. The plugs are in the middle of the cylinder head in case of two-stroke engines. Alternatively, in overhead valve engines, they are positioned on the side of the engine head, next to the valve cover.
What Do They Do?
These little devices emit a bolt of electricity and ignite the fuel and air mixture. Thus, ignition, in turn, makes the pistons move, which keeps the vehicle up and running. Also, spark plugs dissipate heat from the car’s combustion chamber to its engine cooling system. The spark plug’s heat range tells about its ability to dissipate heat.
Sometimes, you may hear these plugs are referred to as ‘cold’ or ‘hot.’ These terms are used to understand your heating range. While changing a hot or cold spark plug, it must be done with caution because if a running spark plug is too hot, then it may damage your engine. If you are still wondering about its functions, you can clear your doubts from auto mechanic Adelaide.
How Do You Understand The Condition of Your Spark Plug?
Once these devices get worn out, it will affect the efficiency of your engine. As mentioned in your user manual, replacing them on time can help you eliminate these problems.
If you are worried about when you should replace spark plugs, then we have created a list of signs and symptoms you can look out for:
1. High Fuel Consumption
Any novice driver or a car owner can spot this issue quickly. A faulty plug can cause your engine to work inefficiently, leading to greater fuel consumption and emissions.
2. Slow Acceleration
An important sight you can look for is slow acceleration or misfiring of your engine. If the spark plug is dirty, it will not spark effectively, making your vehicle feel sluggish. If you notice such signs, then it is time to take your car to a reputable mechanic in Adelaide.
3. Rough Idle
If you notice unusual vibrations and rattling noises from your engine when you are idling, then it is essential to check your spark plug. A faulty or worn-out plug can lead to such issues.
4. Hard Starting
If your vehicle struggles to start, its battery might not always be the problem. As we know by now, sufficient spark must be produced from your spark plugs for your car engine to start. Thus, worn-out plugs may be the culprit if your vehicle is having trouble starting. If you have second thoughts about the spark plug in your car, you must get it checked by a car exhaust system repair. It would help if you did this as soon as possible to keep your vehicle in an optimal state.
Why Does The Spark Plug Go Bad?
We all know that prevention is better than cure. Therefore, you must know why spark plugs wear off so that you can prevent it from happening with the help of car battery repair.
Every time the spark plug creates a spark, it creates an arc of electricity, which shortens the electrodes. Over time, the gap between the electrodes increases; as this gap increases, more electrical current is necessary to ignite the fuel/air mixture. Over time, the performance of your car will decrease, and after a specific time, the spark plug will not spark at all.
Some other causes of spark plug wearing off include oil contamination, carbon buildup, and overhearing caused by pre-ignition.
How Do You Diagnose Worn Spark Plugs?
If you are facing issues with your car’s spark plug, removing and inspecting the device will give you an idea of its condition.
Everyday wear: if you see brownish or greyish deposits on the side of your car, then this is normal wear.
Carbon buildup: If you notice a black spot, then it might indicate a damaged spark plug through carbon buildup.
Wet: If you notice that the device is wet, then it might be a sign of a flooded engine.
Oil buildup: Oily deposits on the electrodes indicate a spark plug damaged by oil. You must track the source of the leaks and consult a car mechanic before a serious problem occurs.
Worn electrodes: If the electrodes have worn out, they need to be replaced.
Burned: If you look at burned electrodes, it is an obvious sign that you need to change your spark plug.
Broken: Needless to say, if you find the electrodes in this condition, then you need to replace them.
If you have no experience handling spark plugs, we strongly recommend seeking assistance from car battery service.
When Should You Consult a Mechanic?
The spark plug maintenance can be a simple or complex process, depending on your vehicle. To conduct proper car exhaust services, your vehicle must be cold before it can be worked on. Therefore, you must plan, as a drop-off might be necessary.
What Happens If I Replace My Car’s Spark Plug on My Own?
For mechanically inclined people, car repair service can be an interesting topic. They can change the spark plugs on their own. However, there are a few things to watch out for, as even a minor mistake can lead to significant engine damage.
For example, using the right tools and the correct size of spark plugs are important. Apart from this, extra care must be taken not to cross-thread spark plugs, and you must see no dirt or debris fall into the device. As a lot can go wrong during DIY repairs, taking your vehicle to a reliable car repair shop is always advisable.
In conclusion, if you notice a faulty spark plug or if your car is simply overdue, it is time to take your vehicle to a car service Adelaide.
