Test 3

Question 1

What type of fuel injection system is the RSA systems?

Answer 1

• Continuous flow system
• It delivers a low pressure continuous flow of fuel to nozzles installed in the intake valve chambers of the cylinders, just outside of the valve.

Question 2

What if there are fuel stains on the atmospheric vent?

Answer 2

-leak/clogged injector

Question 3

Superchargers are driven by a _______?

Answer 3

-belt/the crankshaft

Question 4

What is the source of oil on a supercharger bearing?

Answer 4

Engine oil

Question 5

What controls the amount of exhaust that is routed to the turbine?

Answer 5

Wastegate

Question 6

The APC senses what pressure to the supercharger?

Answer 6

upper deck pressure

Question 7

The ratio controller used with the APC prevents what in the supercharger system?

Answer 7

Opening the wastegate slowing the turbine and maintaining the 2.2 pressure ratio

Question 8

The spring in the automatic wastegate drives the valve to full closed or full open?

Answer 8

full open

Question 9

On the sea level boosted engine the density controller limits manifold pressure

Answer 9

NO

Question 10

In the power recovery (turbo compound) system the turbine wheel shaft… which boost manifold pressure. true or false?

Answer 10

FALSE

Question 11

When engine is running at cruise position which pressure is higher?

Answer 11

Impact pressure

Question 12

Pressure between the compressor and the throttle valve?

Answer 12

Upper deck pressure

Question 13

What closes the wastegate on an automatic turbo charger system?

Answer 13

Engine oil pressure

Question 14

What unit is between the turbine and the compressor?

Answer 14

Bearing housing/Assembly

Question 15

More efficient. Turbocharger or Supercharger?

Answer 15

Turbocharger

Question 16

What is critical altitude?

Answer 16

maximum altitude of a turbocharger aircraft that can maintain certain amount of power

Question 17

Rate of change controller prevents what from happening in the turbocharger system?

Answer 17

To prevent rapid changes in boost resulting from abrupt throttle changes

Question 18

The PRV installed in the upper deck pressure in a turbocharger prevents what?

Answer 18

prevent excessive high pressure or prevent overboosting

Question 19

On sea level boosted engine what does that exhaust bypass valve do?

Answer 19

Similar purpose to wastegate

Maintain atmospheric pressure

Question 20

In power recovery (turbo compound) system the turbine wheel shaft turns what?

Answer 20

Turbine wheel is linked through a fluid coupling to the cranksshaft
