The time between injection and ignition of the fuel is known as __________.

Question 1 of 27070

The time between injection and ignition of the fuel is known as __________.

🔍 Key Concepts

• diesel engine combustion cycle steps: injection, ignition, combustion • difference between injection lag and ignition delay • what actually happens inside the cylinder between fuel spray and flame start

💭 Think About

• Think about the exact instant when fuel first enters the cylinder and the exact instant when it actually begins to burn. What is the period between those two events called? • Which term specifically refers to the time needed for fuel and air to reach conditions (temperature, pressure, mixing) where combustion can start on its own? • Look at each choice and ask: is this about time between events, or some other phenomenon like mixing, turbulence, or burning after the main combustion?

✅ Before You Answer

• Identify which term in the choices is commonly defined as the time interval between start of injection and start of combustion in a diesel engine. • Eliminate any options that describe a process characteristic (like turbulence or burning pattern) rather than a time period. • Make sure the term you choose is used in engine theory to describe the delay before self-ignition of fuel after it has been injected.
