Over loaded engine, excessive fuel injected, injection timing improper,
The turbocharger turbine housing and exhaust manifold on any state of the art high horsepower (per litre of displacement) diesel engine will glow red as it approaches full load condition.
Petrol or gasoline in a diesel will cause internal engine damage. if petrol is used in diesel engine it may cause explosive sound with burning ....bcz high compression ratio ......
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.
High Exhaust Gas Temperature is associated with multiple problem, though most of us concentrate on engine and trouble the fuel and air setting, however the assocaited system (exhaust and air intake) plays the most important role in these kind of defects. Another main coause mat be instrumentation and improper fittment of sensors. While initial trials of engine post installation or major routine, following points are to be considered mandatorily :
diesel has a lower boiling point than antifreeze. as the engine heats up the diesel will vapourize and cause high pressure in your system. you will also has much worse temperature control in your engine.
There are many things that could cause your exhaust temperature to be high. Your exhaust may be plugged for example.
symptoms of high engine oil pressure
because a diesel engine ignites its fuel with pressure, and not with a spark like a petrol engine. that is why a petrol engine does not need as high a compression ratio as a diesel engine
it is produced form animals, plants and factory.
It is the high temp and the high return Pressure inside the injector that causes the fuel To turn black
Diesel Engine has high load factor
The compression ratio of a Diesel ranges from 14:1 to as high as 25:1. I agree just depends on engine.
