Question 87Motor Plants - Assistant Engineer

The correct answer is D) Atomizing. Atomizing is the process of breaking up fuel oil into very fine particles to improve combustion efficiency. This is done by forcing the fuel through a nozzle or orifice, which creates a fine mist or spray of the fuel. Atomizing the fuel allows for more complete combustion, resulting in better engine performance and reduced emissions. The other answer choices are incorrect because they do not describe the process of breaking up fuel oil for combustion. Settling refers to allowing heavier particles to sink, straining involves filtering out larger particles, and spraying is a broader term that does not specifically describe the atomization process.
