🔍 Key Concepts

• Ignition delay period in a diesel engine (time between start of injection and start of combustion) • Effect of longer delay on how much fuel accumulates in the cylinder before it actually starts to burn • Relationship between rate of pressure rise and how quickly a lot of fuel burns once ignition begins

💭 Think About

• When ignition is delayed, what happens to the amount of fuel sitting in the combustion chamber before it starts to burn? More, less, or the same? • If a larger-than-normal amount of fuel suddenly ignites at once, what would that do to the speed of the pressure rise inside the cylinder? • Does a longer ignition delay change compression pressure (from the piston’s movement) or mainly affect what happens after injection begins?

✅ Before You Answer

• Be clear on the definition of ignition delay: it is a time interval, not a pressure or quantity by itself. • Ask whether any option mistakenly confuses compression conditions (set by piston stroke and engine design) with combustion behavior (how fast pressure rises after ignition). • Check which choice best reflects a situation where more fuel than normal ignites nearly simultaneously, and what that does to combustion and pressure rise.
