What is humming in gas turbine?
The formation of combustion oscillations can occur during an operation of a gas turbine burner. This is also known under the concepts of "combustion chamber humming", "combustion chamber oscillations", "combustion-induced pressure pulsations", "oscillating combustion processes". The combustion oscillations are due to an interaction between the quantity supplied per unit time of combustion air/fuel mixture flowing in the flow duct of the burner. The mixture is ignited after entry into a combustion chamber and burns in a flame, with the momentary combustion conversion in the flame. Combustion conversion designates the quantity of combustion air/fuel mixture converted per unit time during a combustion process in a flame. Pressure fluctuations in the combustion chamber, which can lead to the formation of a stable pressure oscillation, can occur due to a change in the combustion conversion. In addition to an increased production of noise, the combustion oscillations cause an increased mechanical and thermal load on walls associated with the combustion chamber and on other parts belonging to the combustion system.

In a gasoline engine the area in the cylinder head where the air and the fuel mixture is burned is called the?
The area is called the combustion chamber.
What is the intake and exhaust valve purpous?
The fuel/air mixture passes through the intake valve to get into the combustion chamber. After combustion, the spent gasses travel out of the combustion chamber through the exhaust valve.
Why air fuel mixture is injected in to combustion chamber instite of fuel?
Injecting an air-fuel mixture into the combustion chamber, rather than just fuel, ensures better atomization and mixing of the fuel with air, leading to more efficient combustion. This process helps achieve a more uniform distribution of the fuel, promoting complete combustion and reducing emissions. Additionally, it enhances engine performance by optimizing power output and fuel efficiency. Overall, this method improves the combustion process and contributes to better engine operation.
The area in the cylinder head where the air-and-fuel mixture is burned is called the?
Combustion chamber.
Why 97 bravada 4.3 turns over but wont start?
You need a spark, a fuel / air mixture supply to have combustion in the combustion chamber.
What is the hottest part of an internal-combustion engine?
The combustion chamber. The temperature of the air/fuel mixture combusting is approximately 1800 degrees f.
What is the most strokes in a car engine?
Internal combustion engines are 4 stroke: 1) Intake (air/fuel mixture is introduced to combustion chamber) 2) Compression (piston rises to compress this mixture) 3) Ignition (spark is introduced to compressed fuel/air mixture ignited same) 4) Exhaust (waste product is expelled from combustion chamber)
In a gasoline engine the area in the cylinder head whee the air and fuel mixture is burned is called?
Fuel and air are mixed in the carburettor and the gas is drawn into the cylinder combustion chamber by the valves. The spark ignites the mixture pushing the valves down and turning the cam shaft, hence "internal combustion". Therefore it is "combustion chamber".
In a gasoline engine the area the cylinder head where the air -and - fuel mixture is burned is called the?
Combustion chamber
In a gasoline engines the area in the cylinder head where the air and fuel mixture is burned is called?
Combustion chamber
What happens during the compression stroke in an internal combustion engine?
During the compression stroke in an internal combustion engine, the piston moves upward, compressing the air-fuel mixture in the combustion chamber. This compression increases the pressure and temperature of the mixture, preparing it for ignition.
