stuck or leaking injector (need more info to correctly solve problem)
It is inside of the fuel tank.
Black smoke = excessive fuel entering the engine
High compression is usually caused by either excessive carbon build up, excessive fuel being injected or oil or coolant getting into the cylinder.
Yes. A sticking fuel injector can allow far too much fuel into a cylinder.
You are missing fuel or spark.
Cylinder heads can flood due to excessive fuel entering the combustion chamber, often resulting from a variety of issues such as a faulty fuel injector, a stuck open valve, or improper engine tuning. This can lead to a condition known as hydro-lock, where the engine cannot compress the liquid fuel, potentially causing severe damage. Additionally, flooding can occur from a malfunctioning carburetor or outdated fuel system components. Proper maintenance and timely repairs are essential to prevent cylinder head flooding.
From the tank, gasoline goes through the fuel line, fuel pump and fuel filter brfore entering the engine. In a fuel-injected engine, it then goes directly to the injectors and gets injected into the cylinder. In a carburated engine, the fuel goes through the carburator, then the intake, and passes through the intake valve into the cylinder.
clogged fuel filter ,bad spark plugs,air leaks in intake
Diesels run on compressed fuel and air. An injector pump sprays fuel into the cylinder and mixes it with the air. When the piston rises to the top of the cylinder it compresses the fuel / air mixture and causes the mixture to ignite powering the engine. The speed of the engine is controled by the throttle plate which controls the amount of air entering the engine as well as the metering valve on the diesel pump which controls the amount of fuel that is sprayed into the cylinder.
Plugged fuel filter. Plugged catalytic converter.
Excess gas coating? Do you mean unburnt fuel is entering the converter? If so, then the fuel/air mixture is too rich, or you have a cylinder that is not firing.
Yes it can if it is clogged or has an obstruction it will most certainly prevent fuel from entering the engine. Check that you have fuel before the filter (incoming) and then check the output of fuel from the filter.
