how to work Reciprocating compressor

 Reciprocating compressor

Reciprocating compressor is a type of positive displacement compressor.We know that   positive displacement compressor are machine in which successive volume of air or gas are confined within a closed space. A reduction in a volume of this   space  result in an increase in the gas pressure.

The  reciprocating compressors are probably the most common of all the types of compressor. it comes in many sizes and configuration such as a single or double acting ,single or multi cylinder with  cylinders arrange in a number of different ways.

The trunk type reciprocating air compressor operate similarly to the two cycle engine with the exception that the crank shaft is driven from an external source. No fuel is injected into the cylinder and the compressed gas is discharge at the peak of the compression stroke into a storage receptacle.

How to two  cycle engine work

A two-stroke (or two-cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during only one crankshaft revolution. This is in contrast to a "four-stroke engine", which requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time.
