Pre-combustion chamber engines inject fuel...

Question 1 of 2707066636eef28f7522a1c5200d5

Pre-combustion chamber engines inject fuel into an antechamber located in the cylinder wall or cylinder head. What is the antechamber referred to when the injection nozzle is located in the main combustion chamber, outside of the antechamber?

🔍 Key Concepts

• Design and purpose of pre-combustion chamber (indirect-injection) diesel engines • How an antechamber assists fuel-air mixing before it reaches the main cylinder • Meaning of terms like swirl, energy, and charging as they relate to combustion chambers

💭 Think About

• Think about what happens to the fuel after it is injected into the antechamber and then passes into the main combustion space—what is that small chamber trying to achieve? • Consider which option name best describes a small passage or chamber that helps start and shape combustion before it fully develops in the main cylinder. • Ask yourself: which term is most commonly associated with creating strong air motion and mixing in indirect-injection diesel engines?

✅ Before You Answer

• Be clear on the difference between direct injection and indirect injection (pre-combustion/antechamber) systems. • Match each option to its primary function: does it store energy, create swirl, assist charging, or act as a pressure reservoir? • Verify which term is specifically used in diesel engine design to describe a small chamber that promotes air swirl and better fuel-air mixing.
