What is the main function of a supercharger in the Volvo Engine Architecture (VEA) petrol engine?

To force larger volumes of air into the engine

Explain why a belt driven supercharger is used in the VEA petrol engine instead of relying solely on a turbocharger.

It allows the engine to deliver high torque from very low revolutions

It increases fuel efficiency at high speeds

It decreases the engine temperature

Compare the operational roles of the supercharger and turbocharger in the VEA petrol engine.

The supercharger is used at low speeds, while the turbocharger is used at high speeds

Both are used at high rotation speeds

The turbocharger is used at low speeds, while the supercharger is used at high speeds

What is the main function of the Roots supercharger as described in the document?

To move a volume of air in pockets between the rotors from the inlet to the outlet without internal compression

To compress air internally before sending it to the engine

To cool the air before it enters the engine

To reduce the pressure in the intake manifold

When is the supercharger normally engaged according to the document?

Directly from idling speed to ensure good response

According to the document, what condition must be met for the supercharger to engage?

Torque request to ECM is above 130 Nm and engine speed is below 2400 rpm

Torque request to ECM is below 90 Nm

Explain why the supercharger creates a pressure higher than the current atmospheric pressure in the intake manifold.

Because it pushes more air into the intake manifold than the engine can use at that moment

Because it compresses air internally

Because it reduces the volume of the intake manifold

Because it cools the air before entering the engine

A vehicle is accelerating from low revolutions and the torque request is above 130 Nm but below 2400 rpm. What will happen to the supercharger?

It will be engaged to provide additional air to the engine

It will be mechanically disengaged via the electrical clutch

It will activate the turbocharger instead

Which of the following is NOT a main part of the supercharger as described in the material?

Two four-bladed, screwed rotors/impellers

Maintenance-free roller and ball bearings

What is the primary function of the rotors/impellers in the supercharger?

To move air from one side to the other with high precision

Why are the impeller blades in the supercharger described as maintenance-free?

They are mounted with maintenance-free roller and ball bearings

Suppose a supercharger’s impeller blades were not mounted with maintenance-free roller and ball bearings. What potential issues could arise in the operation of the supercharger?

Increased need for regular maintenance and possible mechanical failure

Improved air movement efficiency

Reduced weight of the supercharger

What is the function of the gear unit in the supercharger system as described in the material?

To increase the speed of the input shaft in a first stage

To reduce the speed of the rotors

According to the material, what is the gear ratio effect when the crankshaft is at 3500 rpm?

The supercharger runs at approximately 23000 rpm

The supercharger runs at 3500 rpm

The supercharger runs at 7000 rpm

The supercharger runs at 11500 rpm

Which of the following statements is TRUE about the operation of the rotors in the gear unit?

The rotors are driven entirely by the gears and never touch each other

The rotors are directly connected and touch each other

The rotors are driven by a belt system

The rotors are lubricated by water

What is the minimum and maximum torque drawn by an engaged supercharger from the crankshaft, as stated in the material?

At least 12 Nm and at most 30 Nm

At least 5 Nm and at most 20 Nm

At least 20 Nm and at most 50 Nm

At least 10 Nm and at most 25 Nm

If the gear unit is positioned in a bath of 50 ml oil, what is the likely purpose of this oil bath?

To lubricate the gears and reduce friction

To increase the speed of the gears

Given the information about mechanical losses, why is there always a loss when the supercharger is driven by the crankshaft?

Because of the moment of inertia

Because the gears are not lubricated

Because the rotors touch each other

Because the oil bath is too small

What is the primary function of the magnetic clutch in the supercharger system?

To enable the supercharger to disengage from the crankshaft

To increase the speed of the crankshaft

To regulate the temperature of the engine

To control the fuel injection timing

Which signal type is used to control the magnetic clutch engagement?

Pulse Width Modulation (PWM) signal

Why is the ignition lowered during the engagement of the magnetic clutch?

To ensure a smooth engagement by causing a slip

To increase the speed of engagement

To reduce the temperature of the clutch

To disengage the clutch from the crankshaft

How does the control signal change after the initial engagement of the magnetic clutch?

It is reduced to allow the clutch to slip easily

It switches to a different frequency

Explain why a controlled slip is performed during the engagement of the magnetic clutch and how long it typically lasts.

To ensure smooth engagement, lasting about half a second

To prevent overheating, lasting about one second

To increase torque, lasting about two seconds

To reduce wear, lasting about five seconds

What is the primary function of the ECM in controlling the supercharger engagement?

To create a regulated current through the clutch coil

To regulate the engine speed directly

What happens to the friction plate when the current to the clutch coil is disconnected?

It returns to its original position against the companion flange

It remains engaged with the pulley

Explain why the ECM actuates a higher current to the clutch coil when the supercharger is fully engaged.

To ensure the clutch does not start to slip by increasing the magnetic field

To disengage the supercharger quickly

Describe the sequence of events that occur when the supercharger is disengaged.

The voltage supply to the clutch coil is interrupted, the magnetic field disappears, and the friction plate returns to its original position

The clutch coil current increases, the friction plate locks, and engine speed rises

The engine torque increases, the clutch coil is energized, and the friction plate moves forward

The supercharger input shaft accelerates, and the clutch coil is supplied with constant voltage

What is the purpose of the inspection hole in the underside of the supercharger housing?

To check for any wear on the clutch.

To adjust the pulley alignment.

What could be the consequence if the check shows that there is no clearance or the clearance is too small between the friction linings and clutch surface?

The supercharger risks continuous engagement, which can damage the supercharger.

The supercharger will operate more efficiently.

The clutch will automatically adjust itself.

If a defective clutch is found during inspection, what is the recommended action?

Replace the supercharger as a complete exchange part.

Ignore the defect if the supercharger is still running.

Add more lubricant to the clutch.

Explain why it is important to check the clearance between the friction linings and clutch surface in a supercharger. What could happen if this step is neglected?

Neglecting this step can lead to continuous engagement of the supercharger, causing potential damage to the supercharger. Regular checks ensure proper functioning and prevent costly repairs.

It will make the supercharger run faster.

It will improve fuel efficiency.

It will reduce the need for future inspections.
