How to know the condition of the engine by looking at the plug color
Objects car engine or motor can be diagnosed through the plug color display, with a look at the plug color display we can determine the condition of the engine, if the wasteful gasoline engine, the engine under normal circumstances, the engine over heating oil or wasteful.
For details see the picture and description below:
1. The machine is in normal circumstances.
Easily turned on the engine condition, also at low or high rpm, the engine runs fine.
Machine state as above can be seen in the spark plug insulator is brown or grayish. Only a few are used to cover the burning of the electrodes. See the picture below.

2. machine is not normal.
Difficult machine is turned on, the machine is not stable at low speeds. The addition of speed does not work anymore and there was a dead machine.
Nearly 90% of disorders caused by the spark plug engine, carbon deposits caused by dirty (carbon fouling), soiled by oil deposits (fouling oil) and soiled by the deposition of lead (lead fouling).
The cause of the state of the carbon fouling are:
Nearly 90% of disorders caused by the spark plug engine, carbon deposits caused by dirty (carbon fouling), soiled by oil deposits (fouling oil) and soiled by the deposition of lead (lead fouling).
The cause of the state of the carbon fouling are:
- Mistake number usage plugs heat level.
- Excessive consumption of fuel (flooded carburetor, carburetor tuning is too rich, choke is not perfect in the off position. Or carburetor air filter clogged).
- Fuel is not good quality.Too long been used at low speeds.
- Combustion by the spark plug too late.
a. Causes of Oil fouling state are:
- Damage to the piston ring piston ring wear or improper valve estrangement.Fuel and air mixture is not exactly too much fuel (rich mixture).
- In the engine 2 stroke oil mixed boat too much or more than the standard.
- The new machines are down or at the time of overhaul in which pairs of machines using lots of oil.
The cause of the occurrence of lead fouling state is:
Gasoline blended with lead compounds. Former compound is attached to the burning tip of the spark plug. When the vehicle accelerates to high speeds, the compound will melt, causing electrical leakage and cause burning failure.
Machine was faltering at the time of pick up speed (acceleration) or at high speeds.
Machine state as above can be seen in the spark plug insulator also yellow brown. See the picture below.

The cause of Dirt by deposition (fouling deposit) is:
A. Used oil is not good quality.
2. carburettor air filter does not exist or are not in pairs.
3. 4 stroke engine oil to come into the combustion chamber and burned (piston and piston ring wear)
There is an interruption in engine combustion conditions at the time of pick up speed or high speed
State machines can be seen above the insulator and electrode spark plug condition there are deposits of combustion products or crust plugs with a wide range of colors. See the picture below.

The causes of excess heat (over heating) are:
A. The wrong spark plugs heat rate numbers.
2. Appropriate adjustment not ignition, timing ignition too fast.
3. The cooling system is not good.
4. Gas mixture is too thin, too much air.
Engine power is lost and speed was reduced. This arises when the high-speed, long ascent or with heavy loads. If the state is on leave could lead to the spark plugs and pistons can melt perforated Rusk.
State machines can be seen above the spark plug insulator state, which is white and the electrode burn pale purplish color, and looks worn. When this condition is left to the electrode edges may melt. See the picture below.

1. Normal Uniformly
gray or red brick of the spark plug electrode tip to the sleeve. If there are light gray color, then setting the carburetor is too frugal gasoline.If there is a dark or black color, then setting the carburetor is too wasteful of gasoline.
2. Wet End
of the spark plugs wet, wet wet oil is not gasoline, so there's a leak in our machines, can be of rocking piston ring, valve boss engine oil leaks or seal the valve too much to lose / leak. This oil was also burned in the engine combustion chamber and leave the rest of the wet oil. Usually in 2-stroke motors caused by too much oil mixture aside.
3. The crust
is closed this is because the quality of fuel that we use ugly, there is a mixture of dirt, or ignition angle that is too advanced, and could be one select the type of spark plugs.
4. Ceramic flat
this means that the spark plugs are too often sanded so it run out, Replace with new ones.
5. Defect / Damage
that means gasoline that we use so ugly symptoms of detonation or the spark plug electrode distance is too far away. So buy gasoline have to be picky, must not fast, not queued. But do not think the tablets are also good if the gas at the pump, there is also a bad gas station, gasoline + kerosene mixing. Try it once and again check the condition of gasoline that we buy.
6. Full of White Feather
this means there is a leaking radiator fluid and burned in the engine combustion chamber.
7. Melt
this means that the spark plug prematurely burning caused the gasoline octane rating is too poor / low, the degree of the engine ignition is too advanced or too hot.
8. Shiny
Spark plug wet with residual gasoline is not burned, not oil. This means setting the carburetor less fit, less wasteful. Or it could be one choose the type of spark plugs, less cold.

plug Care Tips
Although the shape small. plug (from Dutch Bougie) or spark plug ignition system serves as a means to an electrical fire to burn spark gas mixture in the combustion chamber. Electrical spark is obtained from the high voltage generated by the ignition coil. Without a spark is produced, the machine will not work. In order for the machine work you should be diligent in watching prime condition plug.wrong treatment is one way to clean the spark plugs of dirt and the rest of the lubricant. Here's how the spark plug maintenance.
=> Remove all the spark plugs with a key, do not ever wear pas.Check the key condition. If the plugs dry and crusty gray indicates good combustion conditions of your motor. When wet and the crust is black, describes the combustion engine is less than perfect.
=> Before the plug is removed, the hole where the spark plugs should be cleaned first dwelling. Simply clean with a cloth. When doing the cleaning, check the condition of the spark plug cover is still in good condition. Clean the outside of the mouth of the spark plug with a wire brush. For ease of cleaning, plugs soaked with gasoline or kerosene before cleaning. after a dry cleaner. Clean the electrode with a thin plate stingy. Measure the spark plug gap to optimize the performance of your spark plugs.
=> Review the gap between the positive electrode (rounded part) and the negative electrode (the curve that appears out of the spark plugs). Return to normal position as the user. In general, the spark plug gap is 0.8 mm-1, 2mm.
=> After that insert the plugs in place. Please remember, do not tighten the spark plug up too loud. Because, if it happens again removed the spark plugs would be difficult or may cause damage to the flow of the machine screw in the hole. Clean the spark plugs on a regular basis. So that you can plug service life is longer, you should clean it every 5,000 miles with the wind or with a special brush.Treatment plugs will greatly assist the process of combustion optimization. So that was just the spark plugs, platinum or injector will also be more durable.
