Knowing the condition of the car petrol engines do not have to bother to open the hood or covered in oil. Want to know how easy it is? Just look at the condition of exhaust tip, you can become an expert. Capital is not as difficult as learning a thick book, only the following practical horoscope.
Molten oil
These conditions indicate the existence of engine oil into the combustion chamber in significant quantities. Along with the rest of the exhaust gas, oil will be wasted through the exhaust conduit.
This event can be seen from the molten oil at the end of the exhaust pipe. "When the engine starts, also accompanied by the appearance of dense white smoke". (Ydi / oto-o)
The reason could be because the condition of the piston ring is worn or loose. Or derived from oil seepage due to broken valve seals. Fix or check both of these components before the damage worsens.
Black crust
The crust was attached to the wall of the inner end of the exhaust pipe. If this happens, one might expect too much gasoline is wasted through the exhaust fumes. This condition usually causes wasteful fuel consumption and less power, especially the initial acceleration.
Exhaust emission test results also indicate levels of hydrocarbons (HC) is high (above 200) and the lambda value smaller than the ideal value (one). "The reason for the gas mixture entering the combustion chamber more than air". If this happens, try resetting carburizing system. (Ydi / oto-o)
Gray crust
This condition indicates internal combustion engine is complete. Mixture of air, gasoline and lighters in ideal conditions until combustion efficiency obtained.
Unfortunately, color gray crust is relatively difficult to obtain under conditions of heavy traffic (jam). In this condition, a lot of wasted raw gas through the exhaust. Although the setting is an ideal machine, sometimes crusty black exhaust tip.
Know, Maximum speed car at high rpm on the freeway. Hold for a few minutes. In addition to dispose of the remaining crust in the combustion chamber, is also effective to determine the condition of the exhaust pipe tip. (Ydi / oto-o)
Splashing water
This event normally happens when the condition
the engine is still cold. The water source is not from the engine, but from the effects of condensation (dew) in the exhaust tract. Along with rising temperature in the pipes and mufflers, a splash of water will disappear by itself. This condition indicates the pipeline as well as clean of oil or molten crust that has accumulated.
Debris
This flake out when the engine is spinning at high rpm. The form can be rusty iron or cotton-like objects are burned. It also shows the condition of the filter exhaust (muffler) the loss due to rust. Flakes of rust and Glasswool absorbers inside the muffler off, to come out simultaneously with the exhaust fumes. This condition is usually accompanied by the sound of the roar of the exhaust leak and followed wasteful fuel consumption. (Ydi / oto-o)
