Question 179Motor Plants - QMED
70% to passFuel oil discharged into the diesel engine cylinder is atomized at the _______________.
Aturbocharger
Binjector nozzle tip
Ccarburetor
Dfuel oil pump
AI Explanation
The correct answer is B) injector nozzle tip. At the injector nozzle tip, the fuel oil is atomized into a fine mist, which allows for efficient combustion within the diesel engine cylinder. The high-pressure fuel is forced through the small orifices in the injector nozzle, breaking the fuel into small droplets for optimal mixing with the air in the cylinder. The other answer choices are incorrect because: A) the turbocharger does not atomize the fuel, it only compresses the air; C) carburetors are used in gasoline engines, not diesel engines; and D) the fuel oil pump simply pressurizes the fuel, it does not atomize it.
