5.2.1 Purpose of Air Start System:
· A high pressured compressed air will start cranking the flywheel for a kick start on the crankshaft rotary motion process.
· The energy produced from rotary motion of the crankshaft is then diverted to the reciprocating motion of the pistons.
5.2.2 Operational System:
· When starting the engine, compressed air enters into cylinder with the piston just over TDC pushing the piston downwards.
· As the crankshaft starts rotation, the air start valve on the next cylinder in line opens to continue the momentum.
· The starting air system is linked with the fuel system; hence fuel supply is restricted on starting to keep within a speed limit that has been set before operating at full speed.
· Fuel is injected into the cylinders and the air is cut off when engine runs.
