    Diodes are electronic components that allow current to flow in one direction while blocking it in the opposite direction. They have a specific polarity, with a cathode and an anode, and are designed to conduct current when the voltage across them is above a certain threshold. This property makes diodes useful in various applications such as rectifying AC current to DC current, protecting circuits from reverse polarity, and controlling the direction of current flow.

    Please fill answer below What does the EGR valve do?

    Correct Answer
    Recirculates exhaust gas
    Explanation
    The EGR valve is responsible for recirculating exhaust gas back into the engine's intake manifold. This helps reduce nitrogen oxide (NOx) emissions by diluting the incoming air/fuel mixture with inert exhaust gases. By reintroducing a portion of the exhaust gas, the EGR valve helps lower the combustion temperature, which in turn reduces the formation of harmful pollutants. This process also improves fuel efficiency and engine performance by preventing excessive combustion temperatures that can lead to engine knocking and damage.

      In the trunk

    • D.

      In the gas tank

    Correct Answer
    A. By the gas tank
    Explanation
    The vapour canister is located by the gas tank. This is because the vapour canister is a part of the vehicle's evaporative emission control system, which is designed to capture and store fuel vapours that escape from the gas tank. Placing the vapour canister near the gas tank allows for efficient capture and storage of these vapours, preventing them from being released into the atmosphere.

    If a vehicle has a DOHC engine and is a V6, how many cams would it have?

    • A.

      4

    • B.

      2

    • C.

      6

    • D.

      None

    Correct Answer
    A. 4
    Explanation
    A vehicle with a DOHC (Dual Overhead Cam) engine means that it has two camshafts, one for the intake valves and one for the exhaust valves. Since it is specified that the vehicle is a V6, which means it has six cylinders, each cylinder will have two valves, resulting in a total of twelve valves. Therefore, to control these twelve valves, the DOHC engine would require four cams, two for each camshaft.

    A car's wheelbase is measured from centre of the wheel to centre of a wheel on the same side.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because the wheelbase of a car is indeed measured from the center of one wheel to the center of another wheel on the same side. This measurement is important as it determines the stability and handling of the car. A longer wheelbase typically results in better stability and a smoother ride, while a shorter wheelbase allows for better maneuverability and turning ability.
