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

Working of four stroke petrol engine

• A four stroke engine is an internal combustion engine in which the piston completes four separate strokes while turning the crank shaft. • A four stroke engine delivers one power stroke for every two cycles of the piston. • Following strokes are continuously taking place. ü Suction stroke – Suction of air fuel mixture takes place. ü Compression stroke – Adiabatic compression of air fuel mixture. ü Power stroke – Combustion and adiabatic expansion taking place. ü Exhaust stroke – Burnt gases are exhausted from the cylinder. SUCTION STROKE :- • During suction stroke, inlet valve is opened and exhaust valve is closed. • Piston moves TDC to BDC • When the piston moved TDC to BDC vacuum is created inside the cylinder. • Due to the vacuum air fuel mixtures is drawn into the cylinder. • Inlet valve is closed at the end of suction stroke. COMPRESSION STROKE :- • In compression stroke

Does heat transfer takes place in vaccum space?

Of course! How earth receives heat energy from sun? Here is answer for these two questions. Heat can transfer in vacuum space. In this article you may know how heat is transferred in vacuum space. How earth receives heat energy from sun? First we should understand the modes of heat transfer. There are three modes available to transfer heat. They are, Heat conduction, Heat convection and radiation. Let's see one by one. Heat conduction In heat conduction mode of heat transfer heat is transferred by means of molecules present in the object. In this mode, energy will be transferred among the molecules. Example: I am holding a metal bar in my hand. I am going to heat that. What will happen. The bar gets heat from the source. Unfortunately, I can feel heat transfer in another side which is hold by means of hand. There is no objects present in the space. So heat cannot transfer by conduction mode in space. Heat convection In this mode of heat transfer heat is tr

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

ENGINE AND ITS CLASSIFICATIONS

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.
