What are the internal parts of a motor?
Electric motor designs can vary quite a lot, though in general they have three main parts: a rotor, a stator and a commutator. These three parts use the attractive and repulsive forces of electromagnetism, causing the motor to spin continually as long as it receives a steady flow of electric current.
What are the 4 components of an engine?
For a four-stroke engine, key parts of the engine include the crankshaft (purple), connecting rod (orange), one or more camshafts (red and blue), and valves. For a two-stroke engine, there may simply be an exhaust outlet and fuel inlet instead of a valve system.
What are the 7 engine components?

What 3 major parts are inside an engine block?
The cylinder block is where all the combustion action takes place. The key components here are the combustion chamber, piston, and the crankshaft. 3. The oil sump constitutes the lowermost part of the engine.
What is commutator in motor?
A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. … In a motor the commutator applies electric current to the windings.
What are the two basic components of motors and generators?
The structure of an electric motor consists of two basic parts. There is a rotor, which is made up of coiled wires. The rotor is situated in the middle of a component known as the stator, which is lined with magnets or with coil windings. There is a small air gap between the two.

What is the most important part of an engine?
Flywheel: Flywheel is one of the most important engine components. It is a large and heavy metal wheel. Flywheel is attached to the back of the crankshaft to smooth out the firing impulses.
What is the difference between SI and CI engine?
Difference Between Si engine and Ci engine
Si engine is internal combustion engine that operates on the principle of spark ignition. It uses petrol and utilizes the Otto cycle. The diesel (Ci) engine is also an internal combustion engine, which uses diesel fuel and operates on diesel cycle.
What is liner in engine?
It is a cylinder that is fitted to the engine block to form the cylinder, and is one critical function part that forms the engine interior. In Japan they are usually called Cylinder Liners, but some countries (companies) call them Cylinder Sleeves.
Which is part of CI engine?
Main Components of Compression Ignition Engine
Exhaust Valve: The whole burnt or exhaust from the cylinder thrown out through exhaust valve. Combustion chamber: It is a chamber where the combustion of fuel takes place. Piston: It is reciprocating part of CI engine which does reciprocating motion inside the cylinder.
What are engine components made of?
An engine is made up mainly of various metal alloys, so the material used in the engine and its components can be recycled. The most important structural materials in 4-stroke engines are cast iron, alloy and structural steels, and aluminium alloys.
How an engine works in detail?
The engine consists of a fixed cylinder and a moving piston. The expanding combustion gases push the piston, which in turn rotates the crankshaft. … After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion. The expansion of the combustion gases pushes the piston during the power stroke.
What is the best engine block materials?
The material selected for the engine block is either gray cast iron or aluminum alloy. Both of these metals have good thermal conductivity and fluidity in the molten state. To learn more about these metals click on there names.
