An engine block is the structure which contains the cylinders, and other parts, of an internal combustion engine. In an early automotive engine, the engine block consisted of just the cylinder block, to which a separate crankcase was attached. … Another common term for an engine block is simply “block”.
Where is the block on an engine?
The main structural member of all automotive engines is a cylinder block that usually extends upward from the centre line of the main support for the crankshaft to the junction with the cylinder head.
What does block mean in engines?
Engine Blocks (sometimes called Cylinder Blocks) are the large casings that contain the Cylinder and its internal components, intake and exhaust passages, coolant passages, crankcases, and other internal components.
Is a piston part of an engine?
A piston is a component of reciprocating engines, reciprocating pumps, gas compressors, hydraulic cylinders and pneumatic cylinders, among other similar mechanisms. … In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod and/or connecting rod.
What part of the block is the deck?
Deck. The top surface of the block, where the cylinder head sits, is called the deck . It is machined perfectly flat and mated to the bottom face of the cylinder head . In between the block and the head there will be a head gasket .
What is the difference between an engine block and a cylinder block?
The engine block – also known as a cylinder block – contains all of the major components that make up the bottom end of a motor. … The block was originally just a block of metal holding the cylinder bores, the water cooling jacket, oil passages, and the crankcase.
What are the parts of cylinder block?
Following are the parts of the cylinder block:
- Oil passages and galleries.
- Head studs.
- Core plugs.
- Water pump mounting.
- Oil filter.
What are the parts of cylinder head?
Following are the parts of the cylinder head:
- Head gasket.
- Intake and exhaust ports.
- Head valves.
- Head combustion chamber.
- Spark plugs.
- Fuel injectors.
- Head camshaft.

What is the lower part of the engine block called?
Crankshaft – The crankshaft is located in the lower section of the engine block, within the crankshaft journals (an area of the shaft that rests on the bearings).
What is engine compartment?
Engine compartment means the compartment in which the engine is installed and in which a combustion heater may be installed.
What are the parts of a crankshaft?
A crankshaft consists of crankpins, crank webs (crank arms or cheeks), balancing weights, and main journals. The large end of the connecting rod is attached to the crankpin of the crankshaft. During one stroke, the center-to-center distance between the crankpin and the crankshaft is half of the piston displacement.
What is the engine in a car?
The engine is the heart of your car. It is a complex machine built to convert heat from burning gas into the force that turns the road wheels. … That is why the machine is called an internal combustion engine . As the mixture burns it expands, providing power to drive the car.
What does a crankshaft do in an engine?
The crankshaft is essentially the backbone of the internal combustion engine. The crankshaft is responsible for the proper operation of the engine and converting a linear motion to a rotational motion.
