What are the causes of excessive fuel combustion in the exhaust cylinder system?
2 Answers
Excessive fuel combustion in the exhaust cylinder system is caused by incomplete engine combustion. Causes of excessive fuel combustion in the system: The excessive fuel combustion in the cylinder system may be due to incomplete engine combustion. It is necessary to check and clean the carbon deposits in the engine, including cleaning the throttle valve and fuel injector, and inspecting whether the spark plugs are functioning properly. If the gap is too large, the spark plugs need to be replaced to ensure more complete engine combustion. Additionally, check whether the oxygen sensor is working normally. Classification of cylinders: Single-acting cylinder: It has a piston rod only at one end. Air pressure is generated by supplying air to one side of the piston, which pushes the piston to extend and generate thrust, and returns via spring or self-weight. Double-acting cylinder: Air is alternately supplied to both sides of the piston, generating force in one or two directions.
I've been driving long distances myself for over a decade, and excessive oil in the exhaust pipe is all too common—simply put, it's when the car burns too much oil and it comes out through the exhaust. The most frequent causes are clogged or leaking fuel injectors, which allow unburned gasoline to escape into the cylinders. If your car starts making a rumbling noise accompanied by black smoke, it might be due to a dirty air filter restricting airflow and making the fuel mixture too rich. Another often-overlooked issue is sensor problems, like a faulty oxygen sensor, which can cause the computer to miscalculate fuel injection amounts, leading to over-fueling. Mechanical issues are also a big culprit—my old car once had a turbocharger failure that caused oil to leak and burn excessively. Other common culprits include unstable idling and worn-out spark plugs causing incomplete combustion. Overall, these problems not only waste fuel and money but also pollute the environment. It's crucial to address them promptly to avoid bigger, costlier repairs down the line.
