   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

  VIDEO LECTURE ON ENGINE AND ITS CLASSIFICATIONS ENGINE What is engine ? It is a power generating machine which converts power into motion. Otherwise we can define as, engine is a device which converts heat energy of the fuel into mechanical energy. Example : Petrol engine, Diesel engine INTERNAL COMBUSTION ENGINE What is heat engine? Heat engine is a device which converts heat energy into work. Example: IC engine, EC engine EXTERNAL COMBUSTION ENGINE   What is IC engine ? IC engine also called as internal combustion engine. The combustion of fuel takes place inside of the cylinder. During combustion process, chemical energy of the fuel is converted into heat energy. Further it is converted into useful work. Example : Petrol engine, Diesel engine, Gas turbine.   TURBINE What is EC engine ? EC engine also called as external combustion engine. The combustion of fuel takes place externally. In external combustion engine heat energy is converted into mechanical wo
