### (a) Air Starting System for a 2-Stroke Slow Speed Engine
A line diagram of an air starting system illustrates the path of high-pressure air from storage to the engine cylinders to initiate rotation. The system is designed to provide sufficient torque to overcome the engine's static inertia and compression forces, bringing it to a speed where fuel injection can take over for continuous running.
**System Components and Operation:**
1. **Main Air Receivers/Bottles:** Two or more pressure vessels storing compressed air at approximately 30 bar. They are charged by the main air compressors.
