CARBURETION AND
INJECTION

5. MOD 16 CARBURETION AND INJECTION
Carburetion: It is all the physical processes that prepare the mixture air-fuel
mixture for combustion inside the engines cylinders.
Carburetor: device that prepares this mixture
CLASSIFICATION OF ENGINES according to the mixture procedures
Carburetor engines Float carburetor
Injection carburetor
pressure diaphagram
Injection engines

6. MOD 16 FLOAT CARBURETOR
A. MAIN METERING SYSTEM
a. Venturi (or diffuser) is the main body of the carburetor. It has a narrow
passage or venturi throat. As the air flows through the venturi speed increases
and pressure drops. This decrease suctions or drags part of the fuel that is
located in the tube.
b. Float clamber Function: to keep fuel levels constant through the needle valve,
which is installed in the fuel inlet. This valve opens and closes the entrance hole
to the float chamber depending on fuel levels. As the float rises, the needle
valve begins to close. Once the fuel is at the correct upper level the float closes
completely and the needle valve stops the flow of fuel. This process repeats
continuously.

7. MOD 16 FLOAT CARBURETOR
A. MAIN METERING SYSTEM
c. Throttle Valve (Sometimes referred to as butterfly valve)
consists of a flat, circular piece of metal that is always
installed between the venturi and the engine. It is moved from
the cockpit by engine air level. Function: To meter the amount
of air that passes to the cylinders through out the venturi.

INJECTION CARBURETOR

9. MOD 16 INJECTION CARBURETOR
MAIN METERING SYSTEM
Operation: As filtered air enters the carburetor body, some of it flows into an
impact pressure annulus around the venturi.
As impact air enters the annulus, it’s velocity decreases as it’s pressure
increases. From the annulus, the impact air in directed into chamber air of the
regulator unit, where it presses against one side of the inner (left side)
diaphragm.
At the same time, low pressure air from within the venturi is vented to chamber
B where it acts on the opposite side of the inner diaphragm.

10. MOD 16 INJECTION CARBURETOR
MAIN METERING SYSTEM
Operation (Continuation)
The difference between the impact pressure in chamber A and the suction, or
low pressure in chamber B causes the inner diaphragm to move an amount that
is proportional to the volume of air entering the engine.
The force produced by the pressure differential between chambers A and B is
often referred to as the air metering force and is proportional to the amount of
air that flows through the venturi.

11. MOD 16 INJECTION CARBURETOR
MAIN METERING SYSTEM
Operation (Continued)
As the air metering force builds, it overcomes spring tension and opens
a poppet valve. As the poppet valve opens, a regulated amount of
pressurized fuel is allowed into chamber D. As regulated fuel fills
chamber D, it pushes against the outer regulator diaphragm in an
attempt to close the poppet valve. This fuel metering force balances the
air metering force to hold the poppet valve off its seat an amount that is
proportional to the volume of air entering the engine.

12. MODULE 16 INJECTION CARBURETOR
MAIN METERING SYSTEM
Operation (Continuation)
When the engine is idling, an insufficient amount of airflow exists to
produce a steady air metering force to open the poppet valve.
Therefore the coil spring is provided in chamber A to supplement the
air metering force.
At idle speeds, spring tension forces the diaphragm over and opens
the poppet valve to provide the fuel pressure required to allow the
engine to idle.
