We usually think that one kind of spark plug which is used in all forms of engines. But it is not true. Different types of engine require a different type of plug which fits best with their functionality. Just like spark plugs are the best fit for petrol engines, similarly glow plugs are best fit for diesel engines.
Glow plugs are designed specially for heating devices which help the diesel engines start even in low temperatures. In order to make your diesel engines work efficiently and effectively, you must take care of your glow plugs.
What happens if your glow plugs fail?
It is true that almost all machinery which are exposed to heat and movement tend to worn down over time. In the same way, glow plugs are also worn down over time and eventually break down. As they are the main source which warms up the diesel engines in extremely cold temperatures, it somewhere becomes obvious that without any functional glow plugs present, you might have problems in starting your vehicle during winters. If the situation becomes worse, you might be completely unable to do the same.
It surely goes without saying that such a situation may cause both frustration and monetary losses. To avoid getting into such a mess, you must make sure that your glow plugs are in good working condition, especially if you plan to drive in extremely icy temperatures or apparently live there.
Effect of bad glow plugs on diesel engines’ performance?
Glow plugs helps in the sensitive diesel combustion process that a diesel engine needs in order to function. When there is a presence of bad glow plugs, this results in no supply of extra heat required to ensure proper diesel combustion. This further results in a lot of engine malfunctions.
Some of these malfunctions include:
- Engine misfires
- Loss of fuel efficiency
- Black exhaust smoke
- Decreases in acceleration and power
Even though you are not a pro in driving, you must always make sure that your glow plugs are in a good working condition before embarking on a long trip. Engine issues aren’t something that you would want to accompany you during a long-planned and fun-filled trip.
How to avoid this?
The best part of avoiding this situation is to get your car checked on a timely basis. And if you sense that your car is responding to you in an unusual behavior, you must not ignore them. Instead you must get to mechanic as soon as possible. Though we are not pros in getting such things done, but someone rightly said that “ better late than never.”
