Usually, Two ‘air start’ compressors supply air to the ‘air receivers’.
Air Receivers

Automatic Valve – Stops air going back to the air receivers
The air distributor usually has many pilot valves, one for each cylinder. the distributor opens the air start valves .

The air start valve is located in the cylinder head. When it is opened by the distributor, compressed air goes into the cylinder and forces the piston down.

First, fuel oil comes from the fuel tank and passes through filters before it enters the supply pumps.
From the supply pumps the fuel passes through more filters
Fuel is pumped via a meter so that the quantity of fuel used can be observed

Fuel Oil System process (cont.)Fuel then passes to a buffer tank where it mixes with fuel that has returned from the engine
From the buffer tank fuel oil circulating pumps pump it to the heaters and to the engine
The oil is heated and the temperature of the oil is controlled by a viscosity measuring device.

After the heater and before finally going to the main engine inlet rail the fuel passes through more filters to ensure that there is no dirt which could damage the fuel pumps, injectors and cylinder liner.
From the main engine inlet rail the fuel enters the fuel pump (one per cylinder). The fuel pump delivers the fuel to the fuel injector.
If too much fuel is delivered to the fuel pump, the excess fuel is pumped back to the buffer.
