Engine Instrument System

The principal fault in the pressure type fuel flow meter indicating system, installed on a horizontally opposed continuous-flow fuel injected aircraft reciprocating engine, is that a plugged fuel injection nozzle will cause a

A bourdon-tube instrument may be used to indicate

• Pressure

• Temperature

• Position

• Quantity

A characteristic of dyna- focal engine mounts as applied to aircraft reciprocating engines is that the

Which of the following will decrease volumetric efficiency in a reciprocating engine?

• Full throttle operation.

• Low cylinder head temperatures.

• Improper valve timing.

• Sharp bends in the induction system.

• High carburetor air temperatures.

Which of the following types of electric motors are commonly used in electric tachometers?

• Direct current, series-wound motors

• Synchronous motors

• Direct current, shunt-wound motors

What instrument indicates the thrust of a gas turbine engine?

• Exhaust gas temperature indicator

• Turbine inlet temperature indicator

• Engine pressure ratio indicator

A manifold pressure gauge is designed to

• Maintain constant pressure in the intake manifold

• Indicate differential pressure between the intake manifold and atmospheric pressure

• Indicate absolute pressure in the intake manifold

Excessive valve clearances will cause the duration of valve opening to

• increase for both intake and exhaust valves.

• decrease for both intake and exhaust valves.

• decrease for intake valves and decrease for exhaust valves.

What basic meter is used to indicate cylinder head temperature in most aircraft?

• Electrodynamometer

• Galvanometer

• Thermocouple-type meter

Jet engine thermocouples are usually constructed of

• Chromel-alumel

• Iron-constantan

• Alumel-constantan
