Test 3 Flashcards
What type of fuel injection system is the RSA systems?
- 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.
What if there are fuel stains on the atmospheric vent?
-leak/clogged injector
Superchargers are driven by a _______?
-belt/the crankshaft
What is the source of oil on a supercharger bearing?
Engine oil
What controls the amount of exhaust that is routed to the turbine?
Wastegate
The APC senses what pressure to the supercharger?
upper deck pressure
The ratio controller used with the APC prevents what in the supercharger system?
Opening the wastegate slowing the turbine and maintaining the 2.2 pressure ratio
The spring in the automatic wastegate drives the valve to full closed or full open?
full open
On the sea level boosted engine the density controller limits manifold pressure
NO
In the power recovery (turbo compound) system the turbine wheel shaft… which boost manifold pressure. true or false?
FALSE
When engine is running at cruise position which pressure is higher?
Impact pressure
Pressure between the compressor and the throttle valve?
Upper deck pressure
What closes the wastegate on an automatic turbo charger system?
Engine oil pressure
What unit is between the turbine and the compressor?
Bearing housing/Assembly
More efficient. Turbocharger or Supercharger?
Turbocharger
What is critical altitude?
maximum altitude of a turbocharger aircraft that can maintain certain amount of power
Rate of change controller prevents what from happening in the turbocharger system?
To prevent rapid changes in boost resulting from abrupt throttle changes
The PRV installed in the upper deck pressure in a turbocharger prevents what?
prevent excessive high pressure or prevent overboosting
On sea level boosted engine what does that exhaust bypass valve do?
Similar purpose to wastegate
Maintain atmospheric pressure
In power recovery (turbo compound) system the turbine wheel shaft turns what?
Turbine wheel is linked through a fluid coupling to the cranksshaft
