Q

The principal difference between loop scavenging and cross flow scavenging, as used in single acting diesel engines, is the __________.

🔍 Key Concepts

• Scavenging in two-stroke/single-acting diesel engines and why it’s needed • How loop scavenging routes fresh air compared to cross-flow scavenging • Where the inlet and exhaust ports are located in each arrangement

💭 Think About

• Think about what physically happens to the air path inside the cylinder for each type of scavenging—how does fresh air enter and how do exhaust gases leave? • Which choice describes something that would be fundamentally different between loop and cross-flow designs, regardless of engine timing details? • Consider which option refers to an internal flow pattern versus something that could be similar for many scavenging systems.

✅ Before You Answer

• Compare air flow path in loop vs. cross-flow: does the fresh air loop back, or pass across the cylinder? • Ask yourself: would the port timing/sequence necessarily have to be different between these two, or could it be designed similarly? • Verify which option describes a basic geometric/flow characteristic rather than something that could be adjusted by design (like timing or volume).
