🔍 Key Concepts

• Diesel engine scavenging in two-stroke and four-stroke engines • Difference between charging the cylinder with air vs removing exhaust gases • Role of fresh air flow in clearing out burned gases before combustion

💭 Think About

• Think about what is left in the cylinder right after the power (expansion) stroke and before new combustion can happen. • Ask yourself: is scavenging mainly about putting fresh air in, or about what happens to the exhaust gases when that fresh air moves through? • Consider whether scavenging is defined by the pressure of the incoming air, or by the job that incoming air is doing inside the cylinder.

✅ Before You Answer

• Identify which options focus on filling with fresh air only versus removing exhaust gases. • Check if the definition of scavenging should depend on specific air pressure (atmospheric vs above atmospheric) or on the clearing action inside the cylinder. • Make sure the choice you pick clearly involves getting rid of burned gases so the next charge can be efficiently compressed and ignited.

As it applies to the combustion process associated with diesel engines, what is meant by the term "scavenging"?

Scavenging is the process of filling the cylinder with a charge of fresh air ready for compression.

Scavenging is the process of filling the cylinder with a charge of fresh air at pressures above atmospheric pressure.

Scavenging is the process of filling the cylinder with a charge of fresh air at atmospheric pressure.

Scavenging is the process of removing exhaust gases from the cylinder by blowing in fresh air.
