CPL Acft Tech -Fuel injection, Super/Turbocharging, Exhaust

Advantages of a fuel injection system include which of the following? Select all options that are correct.

• No refrigeration icing

• Better control of fuel to air ratio

• Less maintenance problems

• Better throttle response

A disadvantage of a fuel injection system is...

• a greater chance of fuel line blockages

• over boosting

• greater maintenance issues

• increased wear on the carburetor

The two types of fuel injection systems are;

• direct and continuous flow

• direct and indirect

• continuous and non-continuous flow

• indirect and non-continuous flow

In a direct fuel injection system, the fuel is injected...

• directly into the cylinder head

• via the carburetor into the manifold valve

• directly through the manifold valve

• directly into the intake manifold

Select all of the parts of a fuel injection system...

• injection nozzle

• pump

• float valve

• heater

In a continuous flow fuel injection system...

• fuel is injected continuously into the intake manifold

• fuel is injected continuously into the cylinder heads

• fuel is injected directly into the carburetor

• fuel is metered according to a float valve

True or False.....

Intake icing cannot occur in a fuel injected engine.

• True

• False

Select the correct option below.

• A supercharger is geared directly off the crankshaft

• A superturbocharger (aka "turbocharger") is geared directly off the crankshaft

• A supercharger is geared directly off the camshaft

• A superturbocharger (aka "turbocharger") is geared directly off the camshaft

Which of the following has a 'wastegate'?

• carburetor

• supercharger

• superturbocharger

• impulse coupling

A disadvantage of a turbocharger (aka 'superturbocharger') is...

• backpressure in the exhaust system reduces the efficiency of the engine

• increased friction losses from gearing off the engine result in reduced engine efficiency

• increased propensity for icing

• critical altitude is reduced
