Which component is responsible for mixing air and atomized oil before combustion?

Fuel nozzle
Combustion chamber
Oil pump
Oil strainer

The correct answer is: Combustion chamber

The component that is responsible for mixing air and atomized oil before combustion is the fuel nozzle. The fuel nozzle plays a critical role in the combustion process by atomizing the oil, creating fine droplets that mix with air to ensure a consistent and efficient burn. This atomization is vital, as it allows for improved combustion efficiency and lower emissions. The combustion chamber, while it is where the actual burning of the fuel takes place, does not mix the air and oil. Instead, it serves as the location for combustion to occur after the mixing has already taken place. Other components like the oil pump are responsible for delivering the oil from the tank to the nozzle, while an oil strainer filters impurities from the oil. Each of these other components has its own specific function in the system but does not directly mix the fuel and air for combustion.
