Basic Thermodynamics

First stage of combustion Separately first stage of combustion: When the spark contacts some areas of the fuel then the chemical action begins in those particular areas. The heat generated in this area spreads to the other area of the fuel, where the chemical actions begin in the other area. There is propagation of nucleus of the area in which

First stage of Combustion: Less air is allowed to enter the fuel spray during the first stage of combustion. Hence the fuel supply is also less. The air cross the fuel spray before the chemical action begins. Hence the air is physically in contact with fuel for some time. The time taken for the physical contact is known as the

Internal combustion engine is an engine; it converts the chemical form of energy into the thermal form to produce mechanical output. In this process the combustion takes place inside the engine. In this engine, only exorbitant liquids and gaseous fuels are used for the process. Principles of operations: In the combustion chamber air fuel mixture is ignited by a spark

In the 2 stroke engine it consists of one cycle with one rotation In the 4 stroke engine it consists of one cycle with two rotations. The inlet and the exhaust valves of the 4 stroke engine are replaced by 3 ports in a 2 stroke engine. In 2 stroke engine the lubrication oil must be mixed with the petrol

Super charger acts as an air compressor. It is used to increase the density and pressure of the air that is supplied to the internal combustion engine. In the engine, during the intake of the cycle it takes more oxygen and burn more fuel to accomplish the work. This is due the power increase. By using the belts, gears, shafts,

Thermodynamics One or more forms of works are involved at the same time in a control system. The control volume boundary must be stationary and the moving boundary work must be zero. The work involved in the form of electrical work or shaft work. And also the other form of work must be from fluid, which is flow work. Flow

Thermodynamics is a Greek work Thermo, which means heat and dynamic force. It is a branch of physics which deals with the temperature and their relationship between the work and energy. It defines the variables like Entropy, enthalpy and equilibrium. The thermodynamics deal with the system in equilibrium. Classification of Thermodynamics: Thermodynamics are classified into two types they are Equilibrium
