What is Mechanical Engineering?
Mechanical engineering is a diverse subject that derives its breadth from the
need to design and manufacture everything from small individual part sand devices (e.g., micro scale sensors and inkjet printer nozzles) to large systems (e.g., spacecraft and machine tools). The role of a mechanical engineer is to take a product from an idea to the marketplace.In order to accomplish this, a broad range of skills are needed.
The obvious differences between a two stroke and a four stroke engine:
One difference that is easily noticed is the sound of the engines;
a
two stroke has a higher pitched sound unlike the low pitched sound of
the four stroke engine
Another difference noticed when handling an engine is that a four stroke engine weighs more than the two stroke engine
The types of fluids the engines run on:
A two stroke engine requires gas that is mixed with oil
A four stroke engine doesn't require oil to be mixed with gas; therefore less smoke is produced
certain oils are not recommended for Atv's and dirtbikes because they may harm the engine
Definitions: Reciprocating Air Compressor Terms.
Are you concerned with engineering field? Are you interested in
compressor? Do you have any engineering education?
Before taking up the
actual study of air compressor one must know the important
terms which are frequently used. These definitions are most essential
because they are the fundamentals fair compressor education. One who is
interested in reciprocating air compressor must always remember the
following definitions.
Air Compressor
This is the machine which is used to increase the pressure of air by reducing its volume.
Reciprocating Compressor
This is a machine which compresses air by means of piston reciprocating inside the cylinder bore.
Single Acting Compressor:-
This is a machine which compresses air in only one end of piston and cylinder.
Double Acting Compressor
This is a machine where air is compressed at both end of piston andcylinder.
Single Stage Compressor
This is a machine in which air from atmospheric pressure is compressed
up to desired discharge pressure in single operation (stage).
