What is the main purpose of the carburetor in a reciprocating engine?
To compress the fuel
To mix fuel and air in the correct ratio
To inject fuel directly into the cylinders
To lubricate the cylinders
The correct air-fuel ratio for complete combustion in a reciprocating engine is approximately:
8:1
12:1
15:1
20:1
Which system eliminates the risk of carburetor icing?
Fuel injection system
Induction system plumbing
Dual ignition system
Lubrication system
Carburetor icing is more likely to occur when:
The engine is at full throttle
The relative humidity is low
The temperature is between -5°C and 20°C
The mixture is too rich
The function of the induction system is to:
Control the ignition timing
Provide fuel to the cylinders
Deliver the correct air-fuel mixture to the cylinders
Reduce engine vibrations
A major advantage of fuel injection systems compared to carburetors is:
Lower engine weight
Resistance to icing
Simpler maintenance
Ability to run on any type of fuel
The Continental Powerlink FADEC system provides:
Manual control of fuel and ignition
Automatic digital control of fuel and ignition
Only carburetor adjustment
Only ignition control
In a carburetor, the Venturi is used to:
Increase fuel pressure
Control the throttle position
Create a low-pressure area to draw fuel
Prevent vapor lock
Which component meters the fuel flow in a fuel injection system?
Injector nozzle
Fuel control unit
Induction manifold
Magneto
An excessively rich mixture may cause:
Engine overheating
Detonation
Fouled spark plugs
Higher engine efficiency
