  • 2. 

    __________ monitors amount of O2 in exhaust so ECU can make adjustments.

    Explanation
    An oxygen sensor is a device that monitors the amount of oxygen in the exhaust system of a vehicle. It provides feedback to the engine control unit (ECU) so that it can make necessary adjustments to the air-fuel mixture. This sensor is essential for maintaining optimal fuel efficiency and reducing harmful emissions.

    __________ measures mass of air entering engine.

    Explanation
    The Mass Airflow Sensor is responsible for measuring the mass of air that enters the engine. It is a crucial component in the engine management system as it helps determine the correct air-fuel mixture for combustion. By accurately measuring the amount of air entering the engine, the Mass Airflow Sensor ensures optimal performance and fuel efficiency.

    ____________________ monitors pressure of air in intake manifold.

    Explanation
    The correct answer is Manifold Absolute Pressure. The Manifold Absolute Pressure sensor is responsible for monitoring the pressure of air in the intake manifold. This information is crucial for the engine's control unit to calculate the correct air-fuel mixture and optimize engine performance. By measuring the pressure, the sensor helps ensure that the engine is running efficiently and can detect any abnormalities or malfunctions in the intake system.

    Define Pulse Width-

    Explanation
    The pulse width refers to the duration of time that the fuel injector remains open during each cycle. This duration directly affects the amount of fuel that is delivered to the engine. A longer pulse width means that the injector remains open for a longer period, allowing more fuel to be injected into the engine. Conversely, a shorter pulse width results in a smaller amount of fuel being injected. Therefore, the pulse width plays a crucial role in determining the amount of fuel that the engine receives.
