what is solidworks ? SolidWorks is a popular 3D computer-aided design (CAD) software that is used for creating and designing complex models and assemblies in mechanical engineering, product design, and other industries. It is developed by Dassault Systèmes, a French software company that also owns other popular software such as CATIA and SIMULIA. SolidWorks provides a range of tools and features for creating 3D models, such as sketching, surface modeling, solid modeling, sheet metal design, and assembly modeling. It allows users to simulate and analyze the performance of their designs before manufacturing, including motion analysis, finite element analysis (FEA), and computational fluid dynamics (CFD). It also supports collaboration and sharing of designs with other users through various formats such as STEP, IGES, and STL. SolidWorks is known for its user-friendly interface and intuitive design, which makes it easy for beginners to learn and use. It is widely used in industries such a...
Definition of Engine :
An engine is a device which transforms one form of energy into another form .
Normally ,most of the engines convert thermal energy into mechanical work and therefore they are called heat engines
Definition of Heat Engine:
Heat engine is a device which transforms chemical energy of fuel into thermal energy and utilizes this thermal energy to perform useful work. Thus thermal energy is converted to mechanical energy in a heat engine.
Heat engines can be classified into two categories :
1. I.C.Engines
2. E.C.Engines
I.C. - Internal combustion
E.C. - External combustion
I.C. or E.C. are of two types :
1. Rotary engines
2. Reciprocating engines
External combustion engines are those in which combustion takes place out- side the engine whereas in internal combustion engines combustion take place within the engine.
There are two types of engines :
1. Spark ignition (SI)
2. Compression ignition (CI)
Engine Components :
1. Cylinder Block
2. Cylinder
3. Piston
4. Combustion chamber
5. Inlet Manifold
6. Exhaust Manifold
7. Inlet and Exhaust valves
8. Spark plug
9. Connecting Rod
10. Crankshaft
11. Piston Rings
12. Gudgeon pin
13. Camshaft
14. Cams
15. Fly Wheel
Nomenclature:
1. Cylinder Bore (d)
2. Piston Area (A)
3. Stroke (L)
4. Stroke to Bore Ratio (L/d)
5. Dead Centre
6. Displacement or swept volume (Vs)
7. Cubic capacity or engine capacity (cc)
8. Clearence volume (Vc)
9. Compression Ratio (r)
There are two dead centres in engine .
1. Top Dead Centre (TDC)
2. Bottom Dead Centre ( BDC)
