The main reason for exhaust temprature is the problem with the injectors.the unburnt fuel from the combustion chamber flows to the exhaust manifold while engine works.This unburnt fuel burns in the exhaust manifold burns and causes high exhaust temprature.
For small to mid-sized engines, 4-strokes are more efficient. Small 2-strokes use the same flow of fuel mixed air that they'll later will compress and burn to push the combustion gasses out of the combustion chamber, which means that some fuel gets flushed straight through the engine w/o getting used. Bigger 2-strokes can be either turbo- or supercharged, and then fuel injected. This allows them to use clean air to flush the combustion chamber, and then add the fuel when the chamber is closed. That way, fuel doesn't get flushed through unburnt.
From the combustion of air and fuel in the combustion chamber.
It would be unburnt fuel
in a combustion chamber
A bad injector or an o2 sensor that is bad causing too much fuel to go to the combustion chamber.
In an internal combustion engine, injectors spray atomized fuel into the combustion chamber
The main function is to spray atomized fuel into the combustion chamber of an internal combustion engine.
The fuel gets from the diesel tank to the combustion chamber through fuel injection. This process may vary on your particular vehicle depending on the particular modelÊof your Land Rover Discovery.
The area is called the combustion chamber.
a flooded carburetor will spill fuel into the combustion chamber causing an improper fuel to air mixture. too much fuel in the combustion chamber will not completely burn. the unburned fuel will be pushed out of the exhaust.
The composition of most exhaust fuel is Nitrogen, H20, CO2, and a small amount of CO (from incomplete combustion), HCs (from unburnt fuel), NOx (from excessive combustion temperatures), and ozone.
