Which of the air intake systems listed will require the least amount of brake horsepower to operate?

Question 1 of 27070

Which of the air intake systems listed will require the least amount of brake horsepower to operate?

🔍 Key Concepts

• Brake horsepower (BHP) is the power taken from the engine to drive auxiliary equipment like blowers or pumps • Difference between naturally aspirated and forced induction (turbochargers, blowers) diesel engines • How turbochargers are driven (exhaust gas energy) versus mechanically driven blowers (drawing power from the crankshaft)

💭 Think About

• For each option, ask: does this system take power directly from the crankshaft, or does it mainly use otherwise wasted energy? • Compare which systems are mechanically driven versus those that rely on exhaust gas flow • Think about which option involves no additional moving parts being driven by the engine just to get intake air into the cylinders

✅ Before You Answer

• Identify which choices are mechanically driven by the engine and therefore consume BHP • Identify if any option mainly uses waste exhaust energy rather than crankshaft power • Confirm which system needs no additional power-consuming device to move intake air into the cylinders
