INTERNAL COMBUSTION ENGINE PARTS

   VIDEO LECTURE ON BASIC COMPONENTS OF IC ENGINE INTERNAL COMBUSTION COMPONENTS An Internal combustion engine has various parts. Some important parts are listed below. Cylinder block Cylinder head Cylinder liner Crankcase Piston Connecting rod Crankshaft Cam shaft Flywheel Valve and valve mechanism Gaskets Lubrication system Cooling system Spark plug and fuel injector Cylinder block It is the main body of the engine. It contains cylinder. It is made by casting method. Cast iron, grey cast iron and its alloys are used. Crank shaft, cam shaft are available inside of the cylinder block Water jackets are provided for water cooled engine blocks. Air cooled cylinder block contains fins to reduce the heat produced inside of the engine. The piston reciprocates inside the cylinder. Cylinder head is placed at the top of cylinder block. The crank case is provided at the bottom of the cylinder block.   CYLINDER BLOCK Cylinder head It is made by casting. CI, GCI and its alloys are us

BASICS OF THERMODYNAMICS

    VIDEO LECTURE ON BASICS OF THERMODYNAMIC   Contents Definition of thermodynamics Basic terms used Laws of thermodynamics System, Boundary and Surroundings Equilibrium Intensive and Extensive properties State, Process, Cycle Point and path functions Definition Thermodynamics is the branch of science deals with relationship between heat and work. It deals with transfer of energy within the system and across the boundary of the system.  Basics Terms Used Mass Weight Volume Density Specific weight Specific gravity Specific volume Pressure Temperature Heat Work Power Energy   Mass Mass is the amount of matter contained in an object, and does not depends on gravity. Unit of mass is gram, kilogram. W=mg It is denoted as 'm' Weight The amount of mass depending upon gravity is called weight. It is the product of mass and acceleration gravity. W=mg. Unit is Kgm/sec 2 (or) Newton. It is denoted as'W' Volume Space occupied by the mass. Ratio of mass t
