The reason/feature
|
| A.Vershina of a thermal cone of an insulator from light grey to grey colour. |
Spark plugs are mounted with set калильным number. Engine management (preparation of a fuel mix, ignition system) works according to instructions, mechanical deterioration in admissible values. |
|
B.Vershina of a thermal cone of an insulator of whitish colour.
|
Insulator перегрет. Bad (defective) fuel. Not tight valves. Too small клапанный a backlash. It is necessary to spend measurement of the fulfilled gas. Check up engine management, probably, a poor fuel mix. In case of doubt you risk capital damages of the engine (teases of the piston, прогарение the piston, combustion of the final valve). |
| ввертной candle parts dark, an insulator black. |
Spark plugs монтированы with high калильным number. Candles are worn out. A high share of movement on short distances. The air filter is closed. It is necessary to adjust engine management. The Ljambda-gauge works incorrectly. Exhaust gases black. |
| ввертной candle parts black, an insulator is made oily. |
Look В a high-voltage cable of ignition, the tip of spark plugs are defective. Маслосъемное the piston ring is broken off. Teases of the piston. The lining of a core of the valve is worn out. The high expense of oil. The Sine-black exhaust of the fulfilled gas. |
