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, gasses 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!
Attached to a connection rod, the piston is found in the cylinder where it fits tightly. It moves up and down, compressing the air/fuel mixture which is then combusted.
The engine block is the lower section of the engine. It is cast out of metal and houses the crankshaft, pistons and cylinders.
Spark plugs provide the spark that ignites the air-fuel mixture which starts the motor and keeps it running.
A water pump moves coolant from the radiator through the engine where the excess heat is transferred to it. It then returns to the radiator.
An exhaust valve is found in the cylinder head. It is driven by thencamshaft and releases exhaust gases after combustion.
Found at the bottom of the cylinder block, the oil pan serves as the oil reservoir
The valve cover is bolted onto the cylinder head. It acts as a protective lid.
The balance shaft is a counterweighted engine shaft. It offsets unwanted crankshaft vibrations.
Driven by the camshaft, the intake valve is located in the cylinder head.
Oil keeps all the moving parts of an engine lubricated. An oil filter helps to remove impurities in the oil that might damage the engine.
This controls the amount of air and fuel entering the engine. Too much and the engine will run too rich. Too little and it will run too lean.
Part of the ignition system, the distributor fires the spark plugs in the correct order. It is connected to them by high tension leads.
The single overhead camshaft refers to an engine with one camshaft that operates both the exhaust and intake valves.
The connecting rod forms the mechanical link between the piston and crankshaft. It converts the up and down motion to the crankshaft's rotary motion.
The cylinder liner is also known as a sleeve. It's a replaceable, hollow tube that fits into the cylinder bore.
Head bolts are sometimes referred to as cylinder head bolts. These secure a cylinder head and gasket to the engine block.
When fuel burns in the engine, it pushes the pistons which, in turn, rotate the crankshaft. This causes the vehicle to move.
The electronic control unit ensures optimum engine performance in modern engines.
The oil pump circulates oil within the engine.
When you turn the key of your car, the starter motor begins the combustion process by rotating the engine.
In simple terms, a turbocharger pushes more air into the engine, which, in turn, creates more power as more fuel is burned.
An air filter ensures the air entering the engine, which is used during the combustion process, is kept clean and free of any particles that may damage the engine.
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.
High tension leads connect the sparks plugs to the distributor.
This part is essential to how your engine runs. It allows the fuel/air mixuture into the cyclinder of the engine where it will combust, causing the engine to run. It does this by evenly distrubuting the air/fuel mixture to the intake ports.
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.
This reservoir holds coolant which is used to keep the engine cool during operation. When needed, the coolant is pumped through the engine, taking heat away from it and back to the radiator.
A fuel filter will help to remove impurities that might be in the fuel which, if they get into the engine, can cause complications.
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 and produces more power.
A bearing is a curved metal piece that reduces friction between components. It comes in many different shapes and sizes.
A sprocket is a wheel with a set of teeth on the outer circumference. It drives items like the chain or timing belt.
A DOHC is a Dual (or Double) Overhead Camshaft. It's like an SOHC, but with an extra camshaft.
The oil control ring controls oil consumption within the cylinder. It comes under the umbrella of piston rings.
The timing belt is a toothed belt. It's usually made of reinforced rubber and it rides on the sprockets.
The rocker arm is driven by a pushrod or camshaft lobe. This transfers motions to open and close the valves.
