2. Carburetors & Fuel Injection

3. 1.Describe the major parts of fuel injection. - Air cleaner, mass air flow sensor, injector, pressure regulator, electric fuel pump

4. Carburetors & Fuel Injection 2. Describe a supercharger. - This mechanism pumps air into the engine. It is most useful at high speeds.

5. Carburetors & Fuel Injection 3. Describe a turbocharger. - This mechanism uses exhaust gas to force more air fuel mixture into the engine.

6. Carburetors & Fuel Injection 4. Explain why fuel injection systems are computer controlled. - The fuel injection system is computer controlled to give a 14.7 to 1 air fuel ratio out of each injector.

7. Carburetors & Fuel Injection 5. List the six basic carburetor circuits. - Idle circuit, low speed circuit, high speed full power circuit, acceleration circuit, choke circuit, secondary circuit.

8. Carburetors & Fuel Injection Test 6. How does a carburetor work? - It uses Bernulies theory to create a vacuum to atomize fuel and air at a 14.7 to 1 air fuel ratio.

9. Carburetors & Fuel Injection Test 7. What does a fuel pump do? - The fuel pump supplies fuel from the tank to the intake on the engine.

10. Carburetors & Fuel Injection Test 8. List two types of fuel pumps. - Mechanical and Electric
