________________________________________

Internal combustion engines can be classified into a large number of types based on several criteria. The classification of IC engines is given below:

1. Based on the fuel used

· Diesel Engine

· Petrol Engine (or Gasoline Engine)



2. Based on the type of cycle

· Otto Cycle Engine

· Diesel Cycle Engine

· Dual Cycle Engine



3. Based on the number of strokes per cycle

· Two-stroke Engine

· Four-stroke Engine



4. Based on the number of cylinders

· Single Cylinder Engine

· Multi cylinder Engine

Ø Twin Cylinder Engine

Ø Three Cylinder Engine

Ø Four Cylinder Engine

Ø Six Cylinder Engine

Ø Eight Cylinder Engine

Ø Twelve Cylinder Engine

Ø Sixteen Cylinder Engine



5. Based on the type of ignition

· Spark Ignition Engine (S.I. Engine)

· Compression Ignition Engine (C.I. Engine)



6. Based on the lubrication system used

· Dry sump lubricated engine

· Wet sump lubricated Engine



7. Based on the cooling system used

· Air-cooled Engine

· Water-cooled Engine



8. Based on the arrangement of valves

· L-head Engine

· I-head Engine

· T-head Engine

· F-head Engine



9. Based on the position of cylinders

· Horizontal Engine

· Vertical Engine

· Radial Engine

· Opposed Piston Engine

· Opposed Cylinder Engine

· V Engine

Different types of loads in engineering mechanics are compression, tension, torsion and bending.

Compression:

Compression loading is an effect in which the component reduces it size. During compression load there is reduction in volume and increase in density of a component.

Tension:

Tension is the act of stretching rod, bar, spring, wire, cable etc. that is being pulled from the either ends.

Torsion:

Torsion is the act of twisting of an rod, wire, spring etc. about an axis due to applied couple (torque).

Bending:

Bending is act of changing component from straight form into a curved or angular form.

The purpose of the is to receive the high-pressure gas from the compressor and convert this gas to a liquid . It does it by heat transfer, or the principle that heat will always move from a warmer to a cooler substance.

A is a device that increases the pressure of a substance (usually a gas) by reducing the volume of the substance.
Compressors are used in many applications, most of which involve increasing the pressure inside a gas storage container, such as: Compression of gases in petroleum refineries and chemical plants.

Mechanical seals are devices that are used to provide a seal at the point of entry or exit of a rotating shaft.
Typically it is used to prevent the leakage of one high pressure fluid into a lower pressure fluid .

is an engineering branch that combines engineering physics and mathematics principles with materials science to design, analyze, manufacture, and maintain mechanical systems.It is one of the oldest and broadest of the engineering branches.
