Engine Management System Quiz

What is the purpose of the fuel injection system in an engine?

• To reduce the engine's emissions

• To increase the engine's horsepower

• To cool down the engine

• To deliver the right amount of fuel to the engine's cylinders at the right time.

Name two types of fuel injection systems commonly used in modern engines.

• Port fuel injection and direct fuel injection

• Electronic fuel injection and mechanical fuel injection

• Diesel fuel injection and gasoline fuel injection

• Carburetor fuel injection and throttle body fuel injection

What is the function of the ignition system in an engine?

• Regulating the fuel intake

• Igniting the air-fuel mixture in the engine's cylinders

• Cooling the engine

• Controlling the suspension

Explain the difference between a distributor and distributorless ignition system.

• A distributorless ignition system uses a distributor to route high voltage from the ignition coil to the spark plugs.

• A distributor ignition system uses a distributor to route high voltage from the ignition coil to the spark plugs, while a distributorless ignition system uses individual coil packs for each spark plug, eliminating the need for a distributor.

• A distributor ignition system uses individual coil packs for each spark plug, eliminating the need for a distributor.

• A distributor ignition system uses a distributor to route low voltage from the ignition coil to the spark plugs.

What is the role of the engine control unit (ECU) in an engine management system?

• It controls the tire pressure and air conditioning system

• It regulates the windshield wipers and headlights

• It controls the fuel injection, ignition timing, and other engine functions.

• It is responsible for the radio and GPS navigation system

How does the ECU determine the amount of fuel to inject into the engine?

• Guesswork

• Magic spell

• Sensor inputs

• Random number generator

What is the function of the throttle position sensor in an engine?

• It monitors the tire pressure and alerts the driver when it's low.

• It controls the air conditioning system in the vehicle.

• It measures the temperature of the engine and adjusts the fuel flow accordingly.

• It measures the position of the throttle and sends this information to the engine control unit.

Explain how the throttle position sensor helps in controlling the air-fuel mixture in the engine.

• The throttle position sensor helps in controlling the air-fuel mixture by regulating the oil flow

• The throttle position sensor helps in controlling the air-fuel mixture by monitoring the tire pressure

• The throttle position sensor helps in controlling the air-fuel mixture by adjusting the spark timing

• The throttle position sensor helps in controlling the air-fuel mixture by providing information about the position of the throttle valve to the engine control unit.

What is the purpose of the crankshaft position sensor in an engine?

• To monitor the position and speed of the crankshaft in the engine.

• To regulate the tire pressure in the engine

• To control the temperature of the engine

• To adjust the air-fuel mixture in the engine

Describe the role of the crankshaft position sensor in the engine's ignition timing.

• It monitors the temperature of the engine coolant

• It controls the fuel injection timing

• It regulates the air intake into the engine

• It detects the position of the crankshaft and sends this information to the engine control unit to determine the ignition timing.
