Difficulty: EasyDistinguishing Supported and Unsupported Inferences

Modern diesel engines rely on high-pressure common rail fuel injection to atomize fuel into an extremely fine mist prior to combustion. This thorough atomization allows fuel droplets to mix more evenly with compressed air in the cylinder, leading to a more complete burn. As a result, these modern injection systems increase thermal efficiency and noticeably reduce particulate emissions when compared to older mechanical injection systems.

Statement: Based on the passage, it is valid to infer that the degree of fuel atomization directly influences how completely fuel burns in a diesel engine.

Answer: Answer

Answer

True
The conclusion is directly supported because the author explicitly notes that thorough atomization leads to more complete fuel combustion.

Step-by-Step Solution

1
Identify the claim in the statement
The statement claims that the degree of fuel atomization influences how completely fuel burns.
Clarifying the core claim is necessary to verify whether passage evidence supports it.
2
Locate relevant textual evidence in the passage
The text states that 'thorough atomization allows fuel droplets to mix more evenly... leading to a more complete burn.'
Direct evidence from the passage determines whether an inference is validly supported.
3
Evaluate the logical connection
The text demonstrates a clear causal link between atomization and combustion completeness without requiring outside assumptions.
A supported inference must be a logical deduction grounded directly in the provided text.
