Most motorists know that spark plugs on a car need to be changed regularly. Spark plugs should be replaced in the time frame specified by the manufacturer.
Although there are some car owners who use spark plugs until they no longer work.
We will not discuss in detail the device of the spark plug, the principle of operation and components of the plugs. It will do little to help the driver when replacing the spark plugs in the motor.
Before choosing spark plugs for the car, let’s first define what are spark plugs in the car. So, spark plugs are a special device for igniting the fuel mixture in the combustion chamber of different types of engines. They are in both gasoline and diesel power units. The fuel mixture is ignited by an electrical discharge that occurs between the electrodes of the spark plug.
Car spark plugs can fail for a variety of reasons. But the consequences of their failure for the car will be the same. Beginning car enthusiasts sometimes ask, but what kind of breakdowns can occur with faulty spark plugs? Usually, the spark will disappear, or it becomes insufficient to ignite the combustible mixture. This is bound to affect engine performance.
If the spark plugs are not working, the engine simply will not start or will “Trojit”. The engine “fails” but runs when one or two car plugs are out of order and the others are good.
In addition, premature failure of ignition coils, high-voltage wires, lambda probe and catalytic converter may occur.
These possible causes of engine failure explain why the spark plugs on a car need to be changed regularly, according to the maintenance schedule.
The fact that the replacement of spark plugs on any car should be done in time is clear. But here is what spark plugs to choose for your car. After all, not everyone knows which engine is suitable for which spark plugs denso, ngk or iridium.
Installing on the power unit analog spark plugs instead of the original, you need to be prepared for the fact that they will fail much earlier. Accordingly there will be additional costs.
Of course, in most cases it is written in the instruction manual. But the majority of used cars owners don’t have that manual. When selling cars on the secondary market, this document is often lost or the seller doesn’t give it to the buyer.
Detailed information on the spark plugs for your car can be found in the car’s service and repair manual. Some models of candles are recommended by the car manufacturers and some are allowed for installation. By doing so, they limit the choice of brands. Although one can’t see the light only on the recommended manufacturers.
When choosing candles for the car, one should remember that the spark plugs correctly matched to the engine should satisfy only two conditions.
The most important is not to overheat over 850°C in any operating mode. In addition, ignite the combustible mixture with the electrode before the spark appears. This is called glow ignition.
The ability of spark plugs to self-clean from fouling will be the second fundamental condition that car spark plugs must meet. If your car’s spark plugs are fouled, then they do not meet the requirement specifically for self-cleaning ability.
The caliper number, which describes the ability of a candle to work without the glow of ignition, is the main parameter of a candle. This parameter is necessarily reflected in numbers in the product marking.
You can find out about other manufacturers’ glow plug markings at parts stores or on the websites of those manufacturers.
“Hot” spark plugs are usually used on low-powered, low-energy engines. They are good for removing fouling. But if you install them on a high boost motor, you run the risk of a glow plug ignition.
If you put “cold” plugs on a low-powered engine. Here you run the risk that the parts will fail very quickly. The point is that the warming up of the engine will not be enough for cleaning the plugs from soot. And very quickly the plug will be corked and will stop working.
Specialists consider “cold” plugs, which are better at removing heat from the heated elements. In the “hot” plugs the heat sink is worse, so they are more effective self-cleaning from carbon deposits, but are prone to glow ignition.
In conclusion I’d like to say that the notorious glow plug ignition may turn out to be not at all the consequence of wrong choice of spark plugs. Potassium ignition could be the result of setting an early ignition timing angle, excessive depletion of the combustion mixture or something else.
How often should the spark plugs be changed? To change the spark plugs, it is necessary to comply with the regulation dates and not to delay, then there will be no problems.
