B&S - Carburetor Theory Review

What does a carburetor mix?

• air & fuel

• fuel & water

• air & water

• nothing

What is the job of a carburetor?

• to supply an internal combustion engine with water/fuel mixture

• to supply an external combustion engine with air/fuel mixture

• to supply an internal combustion engine with air/fuel mixture

• to supply an external combustion engine with water/fuel mixture

True/False: The carburetor has components that helps control motor speed.

• True

• False

When a fluid flows into a narrower space, its speed increases but its pressure drops... is referred to as the:

• Vent Effect

• Turi Effect

• Venturi Effect

• Carb Effect

The engine speed is determined by the amount of...

• fuel that goes into an engine through the carburetor

• air that goes to the engine through the carburetor

• water that goes into the engine through the carburetor

____________________ is defined as: the faster air moves, the lower its static pressure, and higher the dynamic pressure is.

• Benoli Principle

• Bernoulli Principle

• Bern Principle

• Fluid Principle

A carburetor venturi __________ at one end, which allows the air flow to increase into the engine.

• widens

• narrows

• remains the same

the most common materials that carburetors are made of are:

• zinc & plastic

• aluminum & plastic

• zinc & aluminum

• aluminum & heilum

Select the answer that includes all parts of a carburetor.

• main body, air flow controls, fuel inlet controls, circuits, jet/fuel metering, venting & air bleeds

• main body, air flow valve, jet/fuel metering, venting & air bleeds

• main body, air flow controls, & fuel inlet controls

• lower body, air flow control valves , circuits, jet/fuel metering, venting & air bleeds

Where is the Venturi located in the carburetor?

• in the fuel passage way

• in the air passage way

• in the water passage way

• in the air & water mixture passage way
