🔍 Key Concepts

• Exhaust manifold back pressure and how it affects engine scavenging efficiency • Differences in how constant pressure and pulse turbocharging systems collect and deliver exhaust gas energy • How smoother, more uniform exhaust flow versus high-energy pulses influence average manifold pressure

💭 Think About

• Think about which system lets exhaust gas escape most freely from the cylinders over time, rather than in sharp pulses. • Consider which system uses a large common manifold and allows pressure to equalize before reaching the turbine. • Ask yourself: does a system that stores and smooths pressure, or one that relies on sharp pressure pulses, tend to have a lower average back pressure in the manifold?

✅ Before You Answer

• Identify which options are actually types of exhaust‑gas energy systems (not just turbine wheel geometry). • Verify which system uses a large common manifold where exhaust from multiple cylinders is collected and pressure is evened out. • Confirm which type of system is known for more uniform, lower average manifold pressure, even if turbine response may be slower.
