Knowing gas colour throw away to represent trivial matter but important as step early to know what is our good vehicle in a condition or do not. If gas throw away chromatic chromatic do not or a little is blue, can be ascertained by combustion take place goodness, because there are correct fuel mixture comparison. When gas throw away brown or rust colored, meaning fuel which follow in course of scanty combustion. If black chromatic show imperfect combustion process, because too much fuel which enter.
Gas throw away which is white chromatic will emerge if lubricating oil too much pouring into into room burn. This matter can be caused by damage at piston, piston ring, cylinder wall, spillway or take the air damage spillway. Or earn because of existence of leakage at packing-packing lead cylinder so that water can pour into into room burn.
Aqueous vapour that happened because combustion heat will seen exit together with gas throw away so that gas throw away white chromatic. But this matter can be differentiated by between white colour condense and turn white lubricating oil vapour. white Vapour chromatic lubricating oil and release aroma. In a state of is the vehicle still can be run, but usage of lubricating oil will become extravagantly.
Gas throw away black chromatic because of fuel mixture too rich air so that do not happened perfect combustion process. There are some possibility causing the the situation, for example air filter stuff up, air spillway closed or damage carburettor.
