• Nozzle

• Injector body

What is the function of the fuel filter in a fuel injection system?

• To remove impurities from the fuel

• To regulate the fuel pressure

• To atomize the fuel

• To control the fuel flow

How does a fuel injection system control the air-fuel ratio?

• By adjusting the fuel pressure

• By monitoring the engine's temperature

• By calculating the precise amount of fuel needed

• By controlling the spark plug timing

Which type of fuel injection system injects fuel into the intake port of each cylinder?

• It reduces emissions

• It requires lower fuel pressure

• It improves engine performance

What is the purpose of the high pressure pump in a direct injection system?

• To increase the fuel pressure

• To atomize the fuel

• To control the fuel flow

• To regulate the air-fuel mixture

Which type of direct injection system sprays fuel directly into the combustion chamber?

• Air guided

• Wall guided

• None of the above

• Spray guided

What component measures the amount of air entering the engine in a fuel injection system?

• Throttle position sensor

• Mass airflow sensor

• Oxygen sensor

• Fuel pressure regulator
