🔍 Key Concepts

• supercharged vs naturally aspirated diesel engines and how extra air is supplied to the cylinders • the effect of increased intake air density/pressure on combustion and power output • the meaning of mean effective pressure (MEP) and what typically happens to it when you add a supercharger

💭 Think About

• Think about what a supercharger actually does to the intake air conditions before it enters the cylinder. Does it change pressure, temperature, volume, or some combination? • Consider which of the listed options is a direct and obvious consequence of forcing more air into the cylinder, rather than a secondary or uncertain effect. • Ask yourself: when you increase the amount of air (and fuel) burned in the same cylinder size, what usually happens to the average pressure during the power stroke?

✅ Before You Answer

• Verify the basic definition: a naturally aspirated engine relies only on atmospheric pressure, while a supercharged engine uses a compressor driven by the engine to raise intake pressure. • Check which choice clearly reflects more mass of air per cycle being inducted into the cylinder. • Be careful with terms like mean effective pressure and blow‑by: confirm whether they always decrease, always increase, or can vary depending on design, instead of being a guaranteed feature of supercharging.
