Question 1 of 27070

Exhaust gases are generally removed from the cylinders of a two-stroke/cycle diesel engine by __________.

🔍 Key Concepts

• Two-stroke diesel engine scavenging and how it differs from four-stroke exhaust processes • The role of pressurized air in clearing exhaust gases from cylinders • How intake and exhaust events overlap in two-stroke engines

💭 Think About

• Think about whether a two-stroke engine has a separate exhaust stroke like a four-stroke, or if something else helps push exhaust out. • Ask yourself what actually forces the burned gases out of the cylinder when the piston is moving and ports/valves are open. • Consider which option describes an active method of sweeping the cylinder clear, rather than just relying on passive flow.

✅ Before You Answer

• Identify which choice involves positive pressure helping to push exhaust out. • Eliminate any options that describe processes more typical of four-stroke engines. • Make sure the option you choose is directly related to sweeping or clearing exhaust from the cylinder, not just how fresh air enters.
