STARTING SYSTEM - DESCRIPTION AND OPERATION
1. GENERAL
The M-14P engine is equipped with a compressed air starting system (Ref. Fig. 1) comprising an air
compressor, compressed air distributor, starting valves, pipelines, compressed air bottle and a fuel priming system.
To start the engine, it is necessary to fill the cylinders with fuel mixture, prepare i-fc for ignition and then to
ignite the mixture. Before starting the engine, gasoline is sucked by the starting pump from the fuel tank and. is fed
to the mixing chamber of the blower through the nozzle screwed into the mixture collector.
At starting the air system valve opens and the solenoid valve button is depressed. The compressed air from
the airplane bottle rushes to the slide valve of the compressed air distributor and then via a pipeline to the starting
valve of the cylinder at the beginning of the power stroke.
Under the action of compressed air the starting valve opens and air gets to the cylinder
combustion chamber.
Compressed air fed to the cylinder moves the piston thus rotating the crankshaft and distributor slide valve
so that compressed air is supplied to other cylinders according to the firing order.
During rotation of the crankshaft, fuel mixture is sucked into the cylinders. The mixture consists of gasoline
injected by the priming pump into the mixture collector and air fed through the carburetor to the engine blower. The
mixture is ignited from the starting coil.
2. AIRBORNE AIR COMPRESSOR AK-50A
2.1. GENERAL
A two-stage air-cooled piston compressor ensures charging of the airplane bottle with
2 compressed air at a pressure of up to 50 kgf/cm •
Compressed air is used to start the engine, control the brakes, retract and extend the landing gear and air
brakes.
