Manual Start: Some DG sets come with a manual start option, allowing operators to start the engine manually in case of any issues with the automatic starting system.
The self-starter ensures the DG set can start quickly and efficiently, especially in emergency situations or during power outages. Proper maintenance of the starter motor and associated components is essential to ensure reliable and efficient starting of the DG set.

t seems there might be a misunderstanding in your query. The term "DG 4 Stock" is not a standard industry term or a specific designation related to diesel generators. It appears to be a combination of terms ("DG" likely standing for Diesel Generator) and "4 Stock," which does not have a clear meaning in the context of diesel generators.

If you are referring to a diesel engine, it might be more appropriate to use the term "4-stroke" or "four-stroke." A four-stroke engine, also known as a four-cycle engine, operates through four stages: intake, compression, power, and exhaust. Here's a brief overview of how a 4-stroke engine works:

1. Intake Stroke:
Air Intake: The engine's intake valve opens, and the piston moves down the cylinder. As the piston moves down, air (or a mixture of air and fuel, in the case of a fuel-injected engine) is drawn into the cylinder.
2. Compression Stroke:
Compression: The intake valve closes, and the piston moves back up the cylinder, compressing the air (or air-fuel mixture). Compression increases the air pressure and prepares the mixture for ignition.
3. Power Stroke:
Ignition and Combustion: When the air (or air-fuel mixture) is compressed at the top of the stroke, a spark plug ignites the mixture. The ignited mixture rapidly expands, creating a high-pressure gas that forces the piston down the cylinder. This downward movement of the piston is what drives the engine's crankshaft, producing mechanical work.
4. Exhaust Stroke:
Exhaust: After the power stroke, the exhaust valve opens, and the piston moves back up the cylinder, pushing out the burnt gases from the combustion process. This prepares the cylinder for the next intake stroke.
This four-stroke cycle is repeated in a continuous sequence as the engine operates, generating power and driving the mechanical components of the diesel generator, such as the alternator to produce electricity.
