Study & experiment on Fuel Supply System of C.1. Engines- Injector & Fuel Pump: Fuel Pump & Injector:- Pump:- P is rack which is connected to the governor mechanism on the accelerator through various linkages. It meshes with quadrant of the gear Q and motion of the rack rotates the quadrant Q. Q is quadrant of the gear to which hollow cylinder portion with slot at the bottom is attached. The slot engaged with the bottom of the plunger R. thus plunger will also rotate as a result of the plunger R. thus plunger will also rotate as a result of the cam mounted on the cam shaft. S is barrel in which fuel enters at the inlet and overflows from fuel overflow passage. V is valve seat. It is non return valve and is kept in position by spring T. When the pressure in the barrel exceeds a predetermined; the valve opens against the compression of the spring and pressure above the valve due to fluid inn the delivery pipe. Thus the pressure developed in the barrel depends upon the stiffness of the spring T & the fluid pressure above the valve. Internal Combustion Engine:- T is spring housed in the body which can be screwed in or out and vary the compression of the spring resulting in the pressure to be developed in the barrel to open the valve. W is the delivery pipe from the pump connected to the injector or atomizer assembly. Injector:- A is the nozzle body. B is the nozzle valve resting on the nozzle body seat. C is the valve cap nut holding the nozzle and the body with the nozzle valve in between. D is the spindle, one end of which resting on the nozzle body valve and the other end on a seat for the spring. E is the spring. The compression of this spring control the pressure at which the nozzle valve can lift up due to fuel pressure. Thus this spring controls the injection pressure. The fuel must be injected at a pressure much higher than the pressure in the cylinder developed due to combustion of fuel air charge. The fuel continues to be injected at the maximum pressure reached in the cylinder. And the fuel to be injected must be atomized and possesses high velocity so that the atomized particles go deep in the combustion space. Thus pressure is as high as 120 and 150 bars or even more might have to be developed to ensure high velocity suitable degree of atomizing and introduction of fuel. F is spring cap nut. G is compression screw to adjust the compression of spring. H is protecting cap for the compression of spring the nut which is vital for the operation of the injector is not mishandled. I is the filling pin when the fuel is injected, the spindle will jump up. This jerking motion of the filling pin ensures injection of fuel. J is the ripple connecting the leak off from the sides of the spindle. K is fuel delivery connection. The valve lifts off the seat against compression of spring when fuel under pressure is fed to the injector.

The model will be suitably sectioned to demonstrate the internal construction details showing the minute information, and working of the same, the model will be suitably painted and mounted on a metal or Mild Steel Sheet base & supplied with key card & very interesting literature regarding working of the same

Study of window air conditioner: The components of window type air conditioners are compressor, condenser, expansion valve or expansion coil, and the evaporator or the cooling coil, all housed in a single box. There is also a motor which has shafts on both sides. On one side of the shaft the blower is connected, which sucks hot air from the room and blows it over the cooling coil, thus cooling it and sending it to the room. On the other shaft the fan is connected, which blows the air over Freon gas passing through the condenser.
