About This Quiz

Your car engine is made up of many, many parts. If one fails, chances are that your car is not moving! So how does it all work? Well, the engine provides the power. This is fed through the transmission, either manual or automatic, to the differential which, in turn, will turn the wheels of the car. Sounds simple enough but it isn't, really. How those engineers worked this all out all those years ago still boggles the mind, don't you think? All those parts have to work in perfect harmony. Pistons moving, valves opening at the right time, spark plugs firing at the right instance, gases moved out of the engine. One little problem and the engine might still run, but not efficiently.

So let's get onto the task at hand. In this quiz, you will be given a description of a car part and a brief idea of what it does in the engine. From that, you will have to identify it from four choices. Seems simple enough, right? Well, some are pretty simple, but what about the inner workings? Do you know all the parts that help make an engine run or the supporting parts, without which the engine wouldn't even start?
 
Up for the challenge? Good! Let's see how you do!

Boosting your engine with nitrous oxide will improve engine ______?
Power
Fuel efficiency
Running temperature
None of the above
Correct Answer
Wrong Answer

Nitrous oxide when heated will split. One of the products of this is oxygen, which when fed into the engine provides more power. Nitrous oxide is commonly known as NOS in the racing world.

From the options below, name the parts of the engine which open and close in a certain sequence.
Oxygen sensor
Muffler
Valves
Pushrod
Correct Answer
Wrong Answer

The valves within an engine open and close in sequence. They do this to let the air and fuel mixture in. Then they seal to allow combustion to take place. Finally, they open to let the gas produced, out.

Which part of the engine is tasked with igniting the fuel/air mixture after the compression stroke?
Glow plug
Spark plug
Carburetor
Rotor
Correct Answer
Wrong Answer

The spark produced by the spark plug is the catalyst that ignites the fuel/air mixture in the cylinder after the compression stroke. This results in the next stroke, the power stroke. Note that a four-cylinder car will have four spark plugs each firing at the right time.

What part of an engine removes impurities from lubricant?
Oil filter
Air intake housing
Circlip
Valve spring
Correct Answer
Wrong Answer

The moving parts of an engine are lubricated by oil. An oil filter helps to remove impurities in the oil that might damage the engine.

What part of the engine moves up and down within the cylinder?
Piston
Engine control unit
Fan
Thermostat
Correct Answer
Wrong Answer

The movement of the piston within the cylinder helps to compress the fuel/air mixture and then produces the power to turn the crankshaft once that is combusted.

Which stroke in the engine cycle helps to squash the fuel/air mixture, making combustion even more powerful?
Exhaust stroke
Intake stroke
Squashing stroke
Compression stroke
Correct Answer
Wrong Answer

The compression stroke in an engine sees the piston move within the cylinder to compress the fuel/air mixture let in by the intake stroke. This allows more energy to release on ignition.

Can you name the part of the ignition system that makes sure the spark plugs fire in the right order?
High tension leads
Distributor
Oil sump
Cambelt
Correct Answer
Wrong Answer

Part of the ignition system, the distributor fires the spark plugs in the correct order. It is connected to them by high tension leads.

Which liquid serves as a lubricant for all internal engine parts?
Coolant
Brake fluid
Gasoline
Oil
Correct Answer
Wrong Answer

Oil, an engine lubricant, is stored here while the engine is not running.
Oil pan
Glow plug
Rotor
None of the above
Correct Answer
Wrong Answer

Found at the bottom of the cylinder block, the oil pan serves as the oil reservoir. A hole in this will soon leave you with a seized engine, a big mess and an even bigger repair bill.

What part on your car must confirm to strict regulations when it comes to engine emissions?
Tailpipe
Muffler
Catalytic converter
None of the above
Correct Answer
Wrong Answer

The exhaust emissions on all modern vehicles are controlled by the catalytic converter. This should always be replaced when the sensors indicate on your dashboard.

Can you name the engine stroke that lets the fuel/air mixture into the cylinder?
In stroke
Entry stroke
Open stroke
Intake stroke
Correct Answer
Wrong Answer

The intake stroke is the first one an engine takes when started. It allows the fuel/air mixture into the cylinder where it is compressed, combusted and the gases produced are removed.

Gases formed by the combustion process are expelled from the engine and leave your car through which part?
Tailpipe
Muffler
Catalytic converter

Advertisement

Can you name the part of your engine which determines when coolant is moved from the radiator for cooling purposes?
Coil
Thermostat
Fuel pump
Solenoid
Correct Answer
Wrong Answer

A thermostat ensures that coolant is only pumped from the radiator once the engine has warmed up sufficiently. If it malfunctions, you'll soon find yourself with steam coming out from under the hood!

Rigid
External
Internal
Light
Correct Answer
Wrong Answer

Although electric and even steam engines were around driving cars at the turn of the 20th century, the internal combustion engine held out to win the race. Of course, hybrid and electric engines are now starting to give it a real run for its money, and in the next 100 years it's possible that it might be phased out completely.

During what stroke of the engine can it lose power?
Intake stroke
Compression stroke
Exhaust stroke
None of the above
Correct Answer
Wrong Answer

During the exhaust stroke of the engine, it can lose power due to something called back pressure. Here, power is lost as the exhaust stroke meets the pressure produced in the stroke process.

Pistons are held in place in the cylinder through which of these below?
Cylinder head gasket
Piston pin clip
Distributor cap
Piston sleeve
Correct Answer
Wrong Answer

The piston pin clip keeps the piston pin in place within the cylinder. To make sure it remains secure, it is connected on both sides.

Can you name the part of your engine that allows the fuel/air mixture into each cylinder?
Cambelt
Air intake manifold
Glow plug
Brake rotor
Correct Answer
Wrong Answer

The air intake manifold allows the fuel/air mixture into the cylinder of the engine where it will combust, prompting the engine to run. It does this by evenly distributing the air/fuel mixture to the intake ports.
