What will cause of diesel engine cylinder high temperature during operation?

On most occassions the fuel system is At Fault. Hightemperatures can be caused by improper atomisation of fuel due faulty fuel injector valves or fuel pumps or incorrect viscosity (which can cause a malfunction of the injector or pump; more prevalent in engines that run on HFO) of the fuel itself. When this happens it has an after effect in the combustion chamber due to residuel fuel after combustion.
Aside from a fault in the fuel system ineffective heat removal of cooling water due to an inefficiency with the radiator can also cause high temperature. And lastly having a burn exhaust valve can also cause high temeperature readings.

How does a diesel engine add fuel to the compress air and it is ignited?
Diesel engine doesn't have spark plug as like petrol engine . But It has an atomizer (A plug through which fuel is sprayed into the combustion chamber).... During Intake Stroke ,the vacuum caused by piston draws air (only) into the cylinder ,Now during Compression stroke Atomizer comes to play ,Spraying Diesel into the cylinder meanwhile the piston compresses the air, so that it's temperature rises to such extent that diesel could be ignited by the heated air, and there comes the power stroke and so on... So ,Conclusion is that Diesel Engine doesn't use spark plug, but the increase in temperature of air during compression is enough to ignited the diesel.. Hope You Got The Answer
What is the maximum temperature produced in diesel engine during cycle?
47
Why during the ignition pressure remain constant in diesel engine?
The ignition temperature, (temperature at which diesel fuel ignites) is 490*F. This temperature corresponds to a set compression of the gasses in the cylinder of the engine. Some, but not all, diesel engines have glow plugs to initially warm the air when you first start the engine because the temperature of the air in the diesel engine is too cold to get the ignition temperature simply from compression. while the engine is running the compression heats the air to the ignition temperature. This compression (or pressure) is the same each time the cylinder fires. Using the universal gas law you can find that corresponding compression versus the ambient temperature and pressure. Typically this will occur at approximately 16 bars. Almost all diesel engines are designed to operate at a compression ratio of 15:1 - 20:1, less if supercharged or turbocharged.
During what stage of engine operation does the piston move upward in the cylinder and force the burned gases out of the cylinder?
Exhaust stroke.
During water heater operation the temperature high limit control may be adjusted?
Never. It is very dangerous to adjust the control during water heater operation.
During what stage of engine operation does the piston move upward in the cylinder and force the burned?
B. exhaust
Why is a thermostat installed in a diesel engine cooling water system?
To control and optimise the working temperature of the engine during differing load conditions.
What has the author Gottfried Behler written?
Gottfried Behler has written: 'Measuring the loudspeaker's impedance during operation for the derivation of the voice coil temperature'
What is thermal drift?
Thermal drift is drift caused by internal heating of equipment during normal operation or by changes in external ambient temperature.
What does diagnostic code P1281 mean on a jeep wrangler?
P1281 means the engine coolant temperature remains below normal during operation. Could be the thermostat.
What is the function of oil temperature gauge in transformers?
Normally, in Transformers due to coil the temperature often rises up to a certain point.To minimise the temperature during transformer operation,specially engineered oil is used.To indicate the level of oil, a gauge is employed.
