too much fuel, excessive oil consumption
They fail because of an engine problem. Engine misfire, engine running too rich, converter contaminated with coolant due to blown head gasket, engine burning oil, & bad spark plugs or wires are the most common causes.
The typical causes are worn piston rings or valve guides.
When the check engine light is on the computer has information that you should know. Connect a code scanner to find out why and most likely it will tell you what is causing the rich burn condition.
The type of heat that causes a burn is gas!
what causes a 125cc motor to smoke and burn oil ? and is it fixable
excessive amount of fuel, running too rich.
you need to tune the carburettor
Worn piston rings allows the oil that is used to lubricate the cylinder walls to enter the combustion chamber.
Steel will start to burn in an oxygen-rich atmosphere at temperatures above 1,600 degrees Celsius (2,912 degrees Fahrenheit). The high heat causes the steel to react with the oxygen, leading to combustion.
The engine crackle sound in a car is typically caused by unburned fuel igniting in the exhaust system. This can happen when the engine is running rich or when there is a misfire in the combustion process.
Could be leaking injectors. Will be repaired (so I'm told) at no cost even if it's not under warranty.
What causes rich farmland in Egypt is when the Nile floods leave rich soil for crops.
