Exam Question

### (a) Control of Fuel Quantity and Timing
On large two-stroke marine diesel engines employing a mechanical-hydraulic control system, the fuel quantity and injection timing are controlled by two distinct but interconnected mechanisms, both originating from the engine governor's response to engine load.
**(i) Fuel Quantity Control (End of Injection)**
The quantity of fuel injected into the cylinder determines the engine's power output. This is controlled by varying the effective stroke of the fuel pump plunger.
