1. Air filter
   Oil filter
2. Camshaft
   None of the above

An air filter ensures the air entering the engine, which is used during the combustion process is kept clean and free of any particles which may damage the engine.

1. Connecting rod bolt
   Intake valve
2. Piston pin bush
   Starter ring

The intake valve is a real valve! It's camshaft-driven and is located in the cylinder head. Its only job is to allow the correct amount of air into the engine for peak performance.

1. Air intake manifold
   Poppet valve
2. Engine block
   None of the above

The engine block is the lower section of the engine. It is cast out of metal and houses the crankshaft, pistons and cylinders

1. Valve
   Pushpin
2. Glow plug
   None of the above

The valves within an engine open and close in sequence to let the air and fuel mixture in. They then seal when combustion takes place and let out the gases produced.

1. Tappet
   Single overhead camshaft
2. Double overhead camshaft
   None of the above

This type of engine has one camshaft. It opens and closes the exhaust and intake valves, which lets the fuel/air mixture into the cylinder and then allows the gases produced during combustion to leave.

1. Alternator
   Starter motor
2. Solenoid
   None of the above

The first starter motors were introduced in 1912, but it took some time for them to become standard on all makes and models of cars.

1. Fuel system
   Ignition system
2. Coolant system
   None of the above

This system helps to start the engine by generating a spark that causes the air-fuel mixture within the combustion chamber to ignite.

1. Fuel rail
   Fuel pump
2. Fuel vapor hose
   Fuel water separator

A fuel pump makes sure fuel gets from the area where it is stored (the fuel tank) to the engine where it is burned to help propulsion. When this fails, your car's engine may turn over when you try to start it but it will not fire.

1. How much gas it burns before running out
   The maximum revs it can run at
2. The line where you fill the oil
   None of the above

If you look at the tachometer (or rev counter) on your dashboard, you will see a red line between 6000 and 7000 revolutions per minute (rpm). This is the maximum amount the engine should spin without causing damage.

1. Rocker arm
   Rubber strip
2. Fan belt
   Ball bearing

A fan belt is made from rubber and connects a number of components of the engine including the cooling fan, alternator and the crankshaft pulley. Sometimes a worn fan belt will make a terrible screeching noise. Time to get it replaced!

1. Exhaust flange gasket
   Valve cover
2. EGR valve
   Connecting rod

The valve cover is attached to the cylinder head. Sometimes called rocker covers, these were not found on early engines, which means valves had to be constantly re-oiled and cleaned of dirt. This cover stops that problem!

1. True
2. False

True! Fuel injection does away with the need for a carburetor. Injectors push fuel into the engine. In engines without them, a carburetor will in fact suck fuel into the engine. Most modern engines are fuel injected.

1. Spark plug
   Piston
2. Connecting rod
   Exhaust manifold

A diesel engine has no need for a spark plug as it does not fire and start in the same way as a gas engine. It uses hot air which has been highly compressed to ignite the fuel instead of the spark from a spark plug.

1. There is a fuel leak in the engine.
   A leak has developed in the valves or piston rings.
2. The oil sump is full.
   None of the above

Oil coating the spark plugs shows leakage, either through the valves or piston rings. This can cause the plugs to misfire and will lead to a drop in overall performance.

1. Cylinder head bolts
   Tappet cover
2. Camshaft locking plate
   None of the above

Head bolts are sometimes referred to as cylinder head bolts. These secure a cylinder head and gasket to the engine block.

1. Intercooler
   Air blower
2. Windpump
   None of the above

Found in turbocharged engines, an intercooler reduces the temperature of the air compressed by the turbocharger. This makes it denser when it is pushed through the engine, which produces more power.

1. 2009 ZR1 Corvette
   AA Capitol
2. Citation
   Nova

The LS9/LSA Chevy V8 engine was first seen in the 2009 ZR1 Corvette. It produces a staggering 638 brake horsepower, thanks to a 6.2-liter displacement and a supercharger!

1. A big block engine will only use diesel as fuel.
   A small block engine uses smaller spark plugs.
2. A big block engine has bigger bores.
   None of the above

Let's look at the example of a V8 engine. BIg block engines have bigger bores over small block engines. This helps them generate more power as the piston moves further. Of course, they are far heavier and much larger.

1. It can catch fire.
   It can grind to a halt and seize.
2. It will perform poorly.
   None of the above

The purpose of oil running through an engine is to lubricate the mechanical parts. Without it, metal will grind on metal and that will cause an engine to seize.

1. 1900
   1971
2. 1992
   1932

V8 engines were certainly not new by the time Ford introduced their first offering in 1932. The Ford V8 produced 65 bhp, which was incredible at the time. It had its problems though. It burned a LOT of fuel, for one thing.

1. Studebaker
   Chevrolet
2. Nash
   Hudson

The Chevrolet V8 small block engine, released in 1955, is somewhat of a legend in the world of motoring. In fact, motoring magazine Ward's Autoworld ranked it as one of their 10 best ever engines made in the 20th Century. The Chevy V8 small block was produced until 2003.

1. It has no oil.
   An engine fire
2. A cracked or warped engine block
   None of the above

If white smoke is coming out of a car's exhaust and it is particularly thick, the engine block is either warped or even cracked. This then allows coolant to flow out, which is then burning in the exhaust system, creating the smoke.

1. Rolls Royce
   Audi
2. Jaguar
   None of the above

Ford has a contract with Jaguar in which they provide engines for the luxury car maker until 2020. At that point, Jaguar will be making their own power plants.

   Chevrolet, Ford
2. Honda, Dodge
   Ford, Dodge

Honda and Chevrolet supply engines to the IndyCar series. The current engine format has been in place since 2012 and sees cars running 2.2-liter V6 power plants. These produce up to 700 bhp.

1. Winner, winner chicken dinner
   Go Fast!
2. Stovebolt
   None of the above

The 'Stovebolt', a straight-six engine from Chevrolet, produced the their small straight-four in a variety of their models. It was available in three options, a 3.0, 3.2 and 3.4-liter.

1. Distributor cap
   Turbocharger
2. Fan belt
   Water pump

In simple terms, a turbocharger pushes more air into the engine, which in turn creates more power as more fuel is burned. Turbochargers can be added to engines but in many new models, they already are part of the engines found on performance models.

1. Thunderbird
   Pinto
2. Model T
   Ka

Certainly not the most powerful but one of the most important engines ever made. Why? Well the Ford Inline 4 drove possible the most significant car in auto history - the Model T.

1. Piston
   Cylinder liner
2. Crankshaft
   None of the above

Combustion of the fuel/air mixture within the cylinder in the engine causes the pistons to move, this in turn moves the crankshaft, which turns the differential and then moves your car. Simply, isn't it!

1. Muntz
   Stutz
2. Imperial
   Ford

Ford's 300 I-6 engine was first produced in 1965 and remained in production for a 31-year period. It was mostly found in their F-truck series. This 4.9-liter 300 cubic engine produced 170 bhp.

1. Z
   W
2. V
   Straight

Z is most certainly not an engine configuration! Most cars are straight (inline or I) formats while you have heard of V6 or V8 powered cars. A W is essentially two V8 engines sitting side by side, as found in the Bugatti Veyron hypercar.

1. It shows how much the fuel can be compressed.
   The higher the octane rating, the slower your car goes.
2. The higher the octane rating, the better your fuel consumption.
   None of the above

The higher the octane rating, the more a fuel can be compressed by a piston together with air before it combusts in the cylinder. Higher octane ratings mean better performance.

1. Fuel tank
   Lubricant container
2. Oil filter
   Oil pan

The oil pan serves as the oil reservoir. It's a removable part that is mounted on the bottom of the cylinder block.

1. Water pump
   Thermostat
2. Fuel line
   None of the above

A thermostat ensures that coolant is only pumped from the radiator once the engine has warmed up sufficiently.

1. Fuel injection
   Fuel suction
2. Fuel pumping
   None of the above

Most modern engines use fuel injection to get the gas into the cylinder, where together with air, it is ignited. Before fuel injection, this was accomplished by carburetion.

1. Fuel injector
   Water pump
2. Fuel pump
   Catalytic converter

Coolant, which is kept in the radiator, is circulated around the engine when it starts to get hot. How? Through a water pump.
