Candle is a small, but certainly an important part of the engine. If you become an observer of the diagnosis, when the spark is absent, it shows the clinical death of a boat motor.
What is the spark plug and how it works?
Are you familiar with this situation: You yank starter cord around ten times in a row, nerves to the limit, and the motor still does not respond?
Or such: You sail on a boat at full speed, after which the motor begins to make unusual sounds - tighter, Then the sound starts to sometimes disappear, and as a result, the engine stalls, and you will be alone on a boat in the middle of the pond himself to himself with nature?
Everything, who has a motorboat, They can not share such a fascinating history. With what it can be connected?
The last two cases are the classics of the genre. If the supply of gasoline is normal, Magneto is functioning normally, and the engine refuses to perform its functions, this indicates, that you are using the wrong spark ignition motor boats.
If you choose the right spark plugs for outboard motor, This will ensure high quality and stable performance of any engine. So you should know a little more about candles, are used for outboard motors foreign production.
If candles divided according to the principle of creating a spark, the candles are divided into several types:
- they, which have an air spark gap;
- they, which possess a sliding spark, etc..
The most popular so far enjoyed first candle type, because they have a rather primitive design, they are easy to make, and they perfectly fulfill their functions in modern engines, boats.
For motor sport boats used candles, which differ in structure from the normal. Since such motors operate in a sufficiently intense thermal regime, to shoot extra warmth, a center electrode plastered special termotsementom, and in the vicinity of the insulator and the insulator sleeve set.
You can buy a good NGK spark plugs in a dedicated online store motorboat parts BoatParts.Com.Ua. In addition to candles you can buy spare parts for boat engines the most “delicious” prices in Ukraine. More information on the company's website or by t: (097) 338-70-70(Viber).
Heat rating and heat output
Heat rating criterion is the ability of the spark plug of the combustion heat to give, which was absorbed. About 75 percent of the heat transferred into the cylinder head through the thread and O-ring. The general principle is that, that cold candles set in engines, which possess high thermal load, eg, racing engines. Warm candles set in engines, which have low thermal load. NGK Spark consists of:
- nut thread type or SAE 4 mm,
- insulator leakage barriers,
- the inner seal,
- suppression resistor,
- not drop down of the sealing ring,
- rolled thread,
- an intermediate electrode with a copper core,
- clearance and the ground electrode.
The most common problem malfunction outboard is, that to the motor chosen candle wrong labeling or design, which is necessary for the production of a specific motor. Therefore, before buying a candle need to carefully consider all the smallest details, that the boat is always pleasing for their excellent work.
