What causes high exhaust temp?
What causes high exhaust temp?
Fouling of the turbine side of the turbocharger is a common cause for high exhaust gas temperatures. The sequence of events is often as follows: → Fouling of turbine (coke deposit) → Bad turbocharger performance → Lower airflow and charge air pressure → Higher exhaust gas temperatures.
What is the influence of engine load on the exhaust temperature of an IC engine?
As the engine load is increased the exhaust temperature increases, this is due to decreased rate of heat transfer through the cylinder wall at higher load. The increase in the external load also results in increase of coolant temperature.
What is the effects of exhaust temperature to the engine performance?
The overall results have shown that boost air temperature has significantly affected the performance as well as emissions of the engine especially at high load. The in-cylinder peak pressure is increase as boost air temperature increase resulted to increase NOx emissions.
Why does exhaust temperature increase with engine speed?
When the engine speed increases, fuel/air ratio decreases, so oxygen in the mixture increases and consequently hydrocarbons (HCs) decrease by increase in exhaust temperature.
What is the influence of engine load on the exhaust temperature?
Engine load is the parameter, if you keep increasing then the thermal efficiency will be increased, same time the combustion will be the batter in case of higher load. Then ultimately the exhaust temperature will increase. Again you may go for to control the exhaust temperature for adding some additives in fuels and other relevant techniques.
What causes high exhaust in a diesel engine?
– Fuel Pump and Delivery valve: If high pressure fuel supply pump or it delivery valve have problems, there maybe a chance of force excess fuel into the fuel valve, which will result to high exhaust temperature or excess smoke from the funnel.
What causes a car to have too much exhaust gas?
Greater load on engine can cause the valve to open more in favor of rich air fuel mixture((greater fuel content) to enter the cylinder. As greater fuel burn in cylinder can rise the temperature of exhaust.
What should the exhaust temperature be in a car?
Hence to boost engine performance, exhaust temperature should be as low as possible. Minimum exhaust temperature signifies complete combustion, maximum power is available at the crank which means higher thermal efficiency.

What happens when exhaust gas gets too hot?
Either way, high exhaust gas temperatures put the engine, exhaust valves, and turbochargers under a tremendous amount of strain and can lead to component failure. This is why we monitor EGT-to keep things from melting, cracking, and breaking. How Hot Is Too Hot for EGT’s?
What causes a car engine to overheat at high pressure?
If the expansion tank is leaking, it may push out coolant and make the air inside the coolant system which causes an overheating engine. The expansion cap does also often have a pressure valve, which makes sure that the coolant system holds a high pressure inside the coolant system, around 1-1.5 bar.
