How A Car Engine Works
Hi, you will now be asked a series of questions that will test to see exactly how much you know about car engines.
Where is the carburetor located in the manifold?
The carburetor is the manifold.
The carburetor is located at the top of the manifold.
The carburetor is located underneath the manifold.
The carburetor can only be found on a bike, not a car.
What are the two methods of mixing air and fuel in a combustion engine?
Using air in a bottle and putting it into fuel.
Putting air into the gasoline tank.
Using a straw and blowing air through it into the engine.
Using a carburettor or fuel injection system.
Where do Electronic fuel injection systems spray fuel at high pressure?
Directly into the exhaust.
Into the wheels so the car moves faster.
Into the Radiator.
Directly into the combustion chamber or into the intake port of the cylinder during the intake stroke.
What is The difference between the initial volume of the cylinder and the final volume at the top of the compression stroke?
The decompression ratio.
The compression volume.
The compression ratio.
The gas ratio.
How is the fuel injected in diesel engines?
By a needle into the compression stroke.
In diesel engines the fuel is injected under high pressure towards the top of the compression stroke.
Through the gasoline tank.
By a hose directly into the engine.
When the piston of an engine compresses the charge, what increases?
An increase in compressive force supplied by work being done by the piston causes heat to be generated.
The amount of horsepower an engine can produce.
The amount of air in the engine.
An increase in the force applied by the work of the wheels.
What are spark plugs used for?
They are used to light my cigarette.
They are used as a source of heat in the winter.
Spark plugs are used as a source of light when looking into the engine.
Spark plugs are used to generate the spark
Do Compression ignition engines such as the diesel engine use spark plugs?
Let me get back to you.
How much voltage is applied to generate a spark?
A voltage around 100 watts is applied.
A high voltage of around 20, 000 Volts is applied.
The same amount of voltage used to light a lightbulb.
Very little voltage is needed to ignite a spark.
Where is the piston at the end of the exhaust stroke?
It's located somewhere under the hood.
The piston is at TDC and one operating cycle has been completed.
In the same place that it started.
Isn't a piston a horse, not part of a car.
When is the exhaust stroke? And What occurs?
It is the initial stroke. It lets out all of the bad odors that exist in the car.
The exhaust stroke happens every other 10 seconds and it ventilates the muffer to get rid of dust/dirt.
The exhaust stroke is the final stroke and it releases air freshner through the air vents of the car.
The exhaust stroke is the final stroke and occurs when the exhaust valve is open and the intake valve is closed. Piston movement evacuates exhaust gases to the atmosphere.
What do typical exhaust gases contain?
A little bit of dust, oxygen and smoke.
Typically exhaust gases contain oxygen, nitrogen, water vapour, carbon dioxide, carbon monoxide, hydrogen, nitrous oxides, particulates and unburned hydrocarbons.
It contains a soothing combination of womens fragrances.
It contains all the dirt in my car that has just been flushed out the muffler.
(useless trick question) If a tree fell in the woods, and no one was around to hear it..would it make a sound?
Yes, trees are heavy and the impact would create noise.
There would be no sound because no one was around to prove it.
Wait, how tall was the tree.
There is no answer to this question.
