If you have a bit of an understanding of your car’s various parts and how they work, then you will feel more comfortable driving it and taking it in for service and maintenance. Perhaps you have realized you need to take your car in for an engine service in McKinney but stopped to ponder what parts make up a car’s engine and how do they work? This knowledge will only benefit you when it comes to taking care of your car, saving you time, effort, and money as well as ensuring your vehicle maintains its value.
The engine is the heart of your car. It is what keeps it alive and running. Gas and diesel vehicles utilize internal combustion engines. The name comes from how the engine works, the fuel and air work together to combust inside the engine which then generates an energy that moves the pistons. The core part of your engine is the cylinder. Inside the cylinder is where the pistons move up and down. Keep reading to learn more about these parts and how they work together.
The different parts that make up your car’s engine consist of: the engine block (cylinder block), the combustion chamber, the cylinder head, pistons, the crankshaft, the camshaft, the timing chain, the valve train, valves, rocker arms, pushrods/lifters, fuel injectors, and spark plugs.
The engine block is the core of your engine. It is usually made of aluminum alloy, and on rare occasion iron. It is also called a cylinder block because of the cylinder tubes that help make it up. The cylinder block is the home for the pistons (where they move up and down). Often cars have more than one cylinder (usually four, six, or eight). The more cylinders that the engine has the more powerful it is.
The combustion chamber is where the energy is transformed in the combustion process. This is the area of the engine in which the fuel, air, electricity, and pressure have an explosive reaction that causes the pistons to move up and down. The movement of the pistons gives the car the power to move.
The cylinder head sits above the engine’s cylinders creating a space at the top of the chamber for combustion. It is also the home for various other parts such as intake and outtake valves, the spark plugs, and the fuel injectors.
As explained before, when the energy is created the pistons then move up in down to give the vehicle power to move. They look similar to cans and are connected to the crankshaft. Pistons also consist of compression rings and oil rings which help to seal the combustion chamber and prevent oil from leaking into that area.
The crankshaft is the part of the engine that rounds out the up and down motion of the pistons. It is connected to rubber belts which are connected to the camshaft allowing for power to be delivered to various parts of the car. The camshaft is connected to the drive train which is the part that transfers power to the wheels.
The camshaft works with the crankshaft, connected by a timing chain, allowing the intake and outtake valves to open and close according to a specific timeline.
The camshaft and crankshaft, as mentioned above, are connected by a timing chain. These parts work together to make sure certain actions take place at certain times, which is vital for the functioning of the engine.
The valvetrain is the part of the engine that controls the movement of the valves. It is made up of the valves, as well as the pushrods and lifters, and rocker arms. It is connected to the cylinder head.
The valves in an engine are the intake valves and the outtake valves. Intake valves work to transfer the air and fuel levels into the combustion chamber. The outtake valves work to move the exhaust that is created from the combustion out of the chamber.
The rocker arms work with the cams (from the camshaft) to press down on the valve system and let the needed air into the chamber or the exhaust out.
In engines (overhead valve engines) in which the camshaft lobes don’t touch the rocker arms, the pushrods/lifters are used in place in the valve system.
For the combustion process to occur, fuel is necessary. The fuel injectors work to move fuel into the cylinders. There are three different fuel injection systems: direct fuel injection, ported fuel injection, and throttle body fuel injection.
There is a spark plugs that resides above each of the cylinders. During the combustion process, the spark plugs spark which ignites the compressed fuel and air and therefore causing the “explosive” process that pushes the piston down.

We might be moving towards electric mobility and alternative-fuels powered vehicles but let’s not forget, it was the internal combustion engines where all the magic began. Known as the heart of a conventional automobile, a car engine is a complex piece of machinery and art. Thousands of mechanical and electronic parts work in tandem to make your beloved possession go like a dream. The parts of a car engine are aligned in a way to strike the perfect between efficiency and performance while also offering a pleasant experience to the driver and the occupants of the car. Let’s learn about how a car engine works!
Talking about the car engine parts names, well, there are plenty of them. From the components of the combustion chambers to the engine parts of the exhaust gas treatment assembly and turbocharger, a typical car engine of the 21st century has got them all. With the advent of technology in the global automotive industry, the innovation quotient of modern-day automobiles has risen exponentially. Hence, what used to be the flagship technology of the past can now be seen deployed in budget vehicles well, for instance, airbags and seatbelt pretensioners.
Are you curious to know about working of engine in car? Today, with this blog, we’ll look at the process of how a car engine works step by step through the anatomy of a car engine to see its car parts engine names and components. We have compiled a comprehensive list of car engine parts that are the most important in making a car engine work properly and to the best of its efficiency and performance levels. So, without further ado, let’s scroll down to know more about the most crucial parts of a car engine and their function and see how they contribute to the characteristics of an internal combustion engine. Please note that here we are considering both petrol and diesel engines. Parts of engine that are exclusive to either one of them would be given a special mention. So, let’s get started with these essential parts of car engine!
1: Engine Block
Topping the list of car engine parts is the engine block. It is one of the main parts of an engine known as the house of all the car engine's main parts. Parts of an engine block are usually made of cast iron or aluminium. The engine block has a well-defined pattern of holes and vents to make space for the cylinders as well as housing the cooling, lubrication and combustion assembly. Not just that, the engine block also contains some of the fundamental and most significant components of a car engine, such as the crankshaft, camshaft, pistons, and all the cylinders. Be it a single-cylinder engine or a W16 one, all of them are contained in the Engine Block only. It is usually the engine block that is displayed in a car engine diagram.
Depending on the layout of the engine, being an inline, boxer, flat or a V, the shape of the engine block and the list of engine parts can change. Among all parts of a car engine, the engine block bears the most flex as it is the mounting point and because it houses the main parts of a car engine and the electrical parts of a car engine.
2: Piston
In the chronological order of importance and functionality, the next car engine part that comes up is the piston or Pistons (in the case of multi-cylinder engines.) A piston is part of an engine better known as the fire-breathing monster. Well, quite literally because they are the components that create the internal combustion in an internal combustion engine, be it a diesel engine or petrol.
Talking about the shape of a piston, they are cylindrical in shape with a flat surface to compress the air-fuel mixture. The piston engine parts are designed in such a way that they convert the most amount of thermal energy generated into mechanical energy and transfer it to the parts of an engine, such as the crankshaft, which eventually moves the vehicle by overcoming the rolling friction. When the spark plugs ignite the air-fuel mixture in the combustion chambers, the movement of the piston happens. This process happens in petrol engines, however, for typical diesel engines, the air-fuel mixture is ignited by compressing it by the force of the pistons.
The primary function of pistons is to get the crankshaft rotating, which eventually spins the wheels via the transmission of a vehicle. The pistons also contain piston rings that act as a sealant to generate and maintain the compression ratio inside the combustion chamber and protect the piston from wear and tear against a cylinder’s inner wall. This gives an overview of how pistons are responsible for the car engine working.
3: Cylinder Head
Another essential car part engine component in the list is the cylinder head. As suggested by its name, the cylinder head constitutes parts of the engine of a car on top of a cylinder block and is sealed with a rubber layer called a gasket to prevent any loss of gases from the combustion chamber.
The cylinder head is home to many of the small but very substantial car engine parts and components of an internal combustion engine that aid in the overall functioning. The list of these car engine parts includes lifters, valves, valve springs, pushrods, rocker arms, camshafts, belt drive assemblies. Basically, this entire assembly of multiple components is responsible for regulating the airflow in the combustion chamber for all the function of engine strokes of a combustion cycle. These components of engine not only channelise the intake airflow but also regulate the passage of exhaust gases leaving the engine.
4: Crankcase
You must have heard about this engine part name, the crankcase. The oil pan and the lower part of the cylinder block together are called the crankcase. It is the bottom portion of the cylinder block, in which the crankshaft is fitted.
Crankcase is a rigid structure made of aluminium or grey cast iron. It is one of the main parts of engine either cast separately and attached to the block with bolts or it can be cast integrally with the engine block.
The crankcase has a simple shape like that of a box but without a bottom. Its bottom half is formed by an oil pan or sump.
The crankcase is designed to support the main bearings and journals of the crankshaft, helping them maintain their axis of rotation’s alignment under different engine loads.
The crankcase gets support with the help of several bearings that are called the main bearings.
5: Oil Pan
Next on the engine parts list is the crankcase’s bottom half is made up of an oil pan or sump which is attached to the crankcase with the help of set screws and a gasket that makes the joint leakproof. This oil pan at the bottom of the crankcase serves as a reservoir to store and cool the engine's lubricating oil.
The bottom of the oil pan contains a drain plug that is used to drain out the used, dirty oil. Generally, the pan is constructed out of aluminium alloy casting or pressed steel sheet.
It stores oil for the lubrication system of the engine.
It collects the return oil draining.
It serves as a container for foreign matters and impurities.
It provides space for cooling of the hot oil.
Oil is drawn from the oil pan by the oil pump and then delivered to all the working parts of the car's engine.
The oil from all these parts drains off and runs down back into the pan.
Thus, a constant circulation of oil between the oil pan and the other parts of the engine is maintained.
6: Manifolds
The exhaust Manifold is a separate set of pipes that are attached to the cylinder head and carry the mixture of air and fuel with the exhaust gases. These parts of a car engine are usually made out of cast iron so they can withstand the extremely high temperatures of the exhaust gases.
It consists of the throttle body, air intake, one intake manifold flange for the tail-pipe, and one flange for a carburettor.
As the air passes through the air intake, it travels through the throttle body and then into the intake manifold. From there, the air passes through the cylinder head into the engine.
The air-fuel mixture is then carried by the inlet manifold from the carburettor to the engine cylinders.
7: Gaskets
Gaskets provide a rigid, tight-fitting joint or connection between two surfaces.
Rubber
Cork
Asbestos
he gaskets should conform to the mating surfaces which may have roughness or warpage.
It should have resistance to high pressures, extreme temperature and vibrations.
The gasket must be impermeable to the fluid.
the gasket should be resistant to the chemicals such as fuel, products of combustion, coolant and engine oil.
The gasket must have apertures for any studs, bolts, opening etc.
Copper-asbestos gasket.
Steel-asbestos gasket.
Steel-asbestos-copper gasket.
Single steel ridged or corrugated gasket.
Stainless steel gasket.
8: Cylinder Liners
Cylinder liners are cylindrical-shaped car engine part that are used in the cylinders to minimise their wear. They are one of the most critical functional parts that make up the engine’s interior.
Cylinder liners of the engine cylinder are made by casting a special alloy iron that contains manganese, nickel, silicon, and chromium. They need to be replaced when they wear out.
Usually, cylinder liners are cast centrifugally. They are quite resistant to wear and corrosion and hence, provide considerably longer engine life.
9: Crankshaft
Well, it’s a common notion in the automobile industry and amongst automobile enthusiasts that the cruciality of the parts of a car engine is decided by how much they can inhibit the vehicle’s movement if they break down. In that regard, the crankshaft is the most critical part of main engine component after the engine itself) of an internal combustion engine assembly. Why? Well, it is the place where power changes hands.
Wondering how car engine works? The engine generates raw power through the combustion in the cylinders, which pushes the pistons down. These pistons are connected to the crankshaft via connecting rods, and this crankshaft is further connected to the transmission of the vehicle. The crankshaft is the ultimate stage for power before its being sent to the transmission. Hence, no matter how many cylinders your engine has got, it will be a stalked engine if the crankshaft isn’t working. Talking about the mechanicals, the crankshaft is a long, perfectly balanced metal rod.
10: Camshaft
The camshaft can be placed at either of two locations, either in the engine block or on the cylinder heads, based on the engine configuration. However, the latest engine technology consisting of a Dual Overhead Camshaft (DOHC) or Single Overhead Camshaft (SOHC) has the camshaft placed in the cylinder head.
The camshaft controls the timing of valves opening and closing to regulate the amount and timing of the entry of the air-fuel mixture and exit of the exhaust gases from the combustion chamber. This entire cycle involves other components as well, such as the pushrods, rockers, and valves.
So, there were some of the essential car engine parts, an explanation of how does a car engine work and some common parts of engine diagram. The car engine parts list can go on and on as there are numerous parts of a car engine. However, the car engine parts names mentioned above are the most fundamental and vital parts of a car engine. They are present in nearly every internal combustion engine, irrespective of fuel and technology. Now, we’ll look at some of the most frequently asked questions about car engine parts.
Ans. As stated above, the main car engine parts are the engine block, cylinders, pistons, cylinder heads, crankshaft, camshaft, rocker arm, etc. Get familiar with these engine parts name and their functions to understand your car better. Spark plugs are parts of petrol engine as diesel engine use compression ignition for combustion.
Ans. Given the complex nature of car parts and especially car engine parts names, one should buy them only from authorised and trusted sellers. They can also be purchased from credible automotive eCommerce platforms such as Carorbis.com where you can search for engine car parts names.
Ans. There are thousands of them, to be precise. Get familiar with the name of engine parts in this blog. Depending on the complexity of the engine, the number of parts increases substantially. The number of moving parts also varies from one type to another type of engine, such as internal combustion, hybrid or alternate fuel-powered engine, while diesel engine components are a little different from some petrol engine parts.
Ans. The proximity to roads and the continuous exposure to heat and stress can cause engine parts to collect layers of deposits such as sludge, grease, dust, etc. Hence, the main parts of a car need to be cleaned thoroughly and at regular intervals. There are three main methods to clean an engine:
The wet cleaning method is the most widely deployed method in automotive workshops where the affected components are submerged into a cleaning solution and then installed back in place.
Ans. Well, you can refer to the owner’s manual of the particular car where the engine parts would be clearly mentioned. The owner’s manual will list engine all parts name in the index. The best practice to identify an engine part is noting down the Vehicle Information Number or VIN and then matching it with the brand dealers. Car dealers and OEMs register the vehicle and car engine data with respect to the VIN.
Ans. You can take a look at the cylinder head. The number of pipes in the exhaust manifold depicts the number of cylinders. Usually, most smaller capacity engines are inline engines where the cylinders are placed in line with respect to each other. However, the higher-performing engines are more likely to be V-type which have the cylinders stacked in the form of V. In addition, parts of a petrol engine are a little different from diesel engine parts. Getting to know car engine parts name will help you better understand the type of engine.
