Name the part of the engine that moves up and down within one of the cylinders.
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.
All major engine parts are found here.
The engine block is the lower section of the engine. It is cast out of metal and houses the crankshaft, pistons and cylinders.
This plays an important part in starting your engine. Name it.
Spark plugs provide the spark that ignites the air-fuel mixture which starts the motor and keeps it running.
Identify the part that moves coolant through the engine when it's hot.
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.
Gasses that form as a result of the burning of the fuel/air mixture are released into the exhaust system through this. What is it called?
An exhaust valve is found in the cylinder head. It is driven by thencamshaft and releases exhaust gases after combustion.
Oil, an engine lubricant, is stored here while the engine is not running.
Found at the bottom of the cylinder block, the oil pan serves as the oil reservoir
What is the name of the protective piece bolted to the cylinder head?
The valve cover is bolted onto the cylinder head. It acts as a protective lid.
Unwanted crankshaft vibrations are stopped by this engine shaft which is counter weighted. It is called a ___________________.
The balance shaft is a counterweighted engine shaft. It offsets unwanted crankshaft vibrations.
The amount of air/fuel mixture taken into the engine is controlled by this part.
Driven by the camshaft, the intake valve is located in the cylinder head.
Identify the part that helps keep impurities out of the lubricant that moves around the engine.
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.
In older engines without fuel injection, this part controls the amount of fuel/air entering 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.
Can you name the part of the ignition system that makes sure the spark plugs fire in the right order?
Part of the ignition system, the distributor fires the spark plugs in the correct order. It is connected to them by high tension leads.
This engine part is often abbreviated to SOHC.
The single overhead camshaft refers to an engine with one camshaft that operates both the exhaust and intake valves.
This part connects the piston to the crankshaft.
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.
Also known as the sleeve, the piston moves near this part and it fits in the cylinder bore.
The cylinder liner is also known as a sleeve. It's a replaceable, hollow tube that fits into the cylinder bore.
These fasteners secure the cylinder head to the engine block.
Head bolts are sometimes referred to as cylinder head bolts. These secure a cylinder head and gasket to the engine block.
Moving pistons rotate this part, which ultimately leads to the vehicle moving. Name the part, please.
When fuel burns in the engine, it pushes the pistons which, in turn, rotate the crankshaft. This causes the vehicle to move.
The 'brain' of the engine, this measures many variables to see that everything is performing properly.
The electronic control unit ensures optimum engine performance in modern engines.
This ensures lubricant flows through the engine so that all moving parts move easily. What is it?
The oil pump circulates oil within the engine.
Without this part, the engine won't turn over when you turn the key.
When you turn the key of your car, the starter motor begins the combustion process by rotating the engine.
This engine part, not found in all cars, gives the car far more bang for its buck! Any ideas what it is?
In simple terms, a turbocharger pushes more air into the engine, which, in turn, creates more power as more fuel is burned.
Air entering the engine is a crucial part of the combustion process and this part makes sure it is clean.
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.
By opening and closing in a certain sequence, these parts allow the air/fuel mixture into the cylinder and the gasses out once combustion has taken place. Name them, please.
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.
These connect the spark plugs to the distributor. What are they?
High tension leads connect the sparks plugs to the distributor.
Name the part that lets air into the engine to mix with fuel.
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.
This moves the propellant that drives the engine from the storage area to where it is needed for combustion.
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.
Identify the reservoir that stores coolant that keeps the engine operating at the right temperature, please.
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.
Fuel entering the engine must be clean. This ensures it is.
A fuel filter will help to remove impurities that might be in the fuel which, if they get into the engine, can cause complications.
In a nutshell, this makes the air entering a turbocharged engine cooler.
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.
This part helps to reduce friction between various components and comes in different sizes.
A bearing is a curved metal piece that reduces friction between components. It comes in many different shapes and sizes.
This part includes a set of teeth.
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.
Name the small ring that controls the rate of oil consumption within the engine's cylinders.
The oil control ring controls oil consumption within the cylinder. It comes under the umbrella of piston rings.
Identify a belt with teeth that helps ensure the engine runs efficiently .
The timing belt is a toothed belt. It's usually made of reinforced rubber and it rides on the sprockets.
Name the lever that moves when the pushrod within the engine moves.
The rocker arm is driven by a pushrod or camshaft lobe. This transfers motions to open and close the valves.
