Konse difference ha petrol and diesel engine me

konse difference ha petrol and diesel engine me

Hello friend aj ham janege petrol or diesel engine me kya difference ha. yani petrol or diesel engine me kya kya difference ha. so petrol engine ko ham SI engine kehte ha or diesel engine ko ham CI engine kehte ha. SI engine ka matlab ha spark ignition eska matlab petrol engine me power stroke ke time pe power produce hota ha. air fuel mixture jalane ke liya electric spark ki jarurat hoti ha. vo spark produce hone ke liya spark plug use karte ha. or vo spark 20,000V (DC) power pe produce hota ha. or diesel engine ko ham CI engine matlab compress ignation bhi kehte ha. eska matlab air +fuel mixture ko burn karne ke liya power stroke ke time per jis external factore ko use Kiya jata ha use compression kehte ha. jab piston TDC to BDC piston travel hota ha us samai compression se jo temperature or pressure generate hota ha vo sahi hona chahiya  tabhi air + fuel mixture sahi se jalta ha.

FLUID MECHANICS & MACHINERY ki jankary gate ke liya


         Matter exists in three phase solid, liquid and gas. The phase of matter depends upon the inter-molecular attraction between two molecules. Solid is inter-molecular forces are very strong. Molecules very close to one another. Liquid is inter-molecular forces are weak. More space between the molecules. Gases is inter-molecular forces are very weak. More space between the molecules. Fluid is defined as substance which has capacity to flow. That deform continuously under the action of shear stress, no matter if it is small. NO definite shape of its own, but conforms to the shape of container. Fluid mechanic is branch of engineering science which is deals with the behaviors of the fluids at rest as well as in motion HYDRAULICS is topic in applied science and engineering dealing with the mechanical properties of liquids.

Made easy handwritten class notes gate free download basic thermodynamics 2018[ PDF ]

Basic thermodynamics 

Made easy study material and books  for mechanical engineering gate notes available on this site you can download free and made easy books for mechanical engineering available.
Thermodynamics is the branch of science which deals with energy interaction and it's effect on system and surrounding Energy is can be understood as the ability to cause changes System System can be a fixed mass or a region in space where our study in focused Surroundings is a Every thing except the system is called surrounding. The part of the surrounding which is directly affected by the system is called immediate surrounding Boundary is a real or imaginary surface which separates the system from the surrounding Boundary can be fixed or movable.

TYPES of system Pressure (gases) Acceleration to kinetic theory of gases the molecules of the gases are in continuous random motion and due to there random motion they collide with one or other and the walls of the container due to this collision force is extorted and avg normal force per unit area is termed pressure.


Properties of the system:-Any characteristics of the system is called property of the system Properties can be classified as 1) Intensive, 2) Extensive .Intensive (intrinsic) Independent of mass of the system under consideration eg. Pressure, temperature, density etc. All specific properties are intensive property eg. Sp.  Volume, sp. Enthalpy, sp.  Internal energy etc. Extensive (Extrinsic):-Depends on mass of system under consideration eg.  Volume, Internal energy, Enthalpy, entropy etc. State of the system and processes:-Any condition of the system is called as state of System State is specified by the properties of system If any one of the property changes, the state of the system changes.  The change in state of system is called process. the infinite state through which the system pass, while going the initial state to a final state is called process path.

The processes can be classified as : 1) Quasi-static 2) Non-Quasi-static A process is said to be a quasi-static process if it takes place infinitely slowly otherwise non quasi-static In quasi-static process the properties remain uniform throughout where as in non-quasi-static process the properties are non-uniform Friction-less quasi-static processes are reversible processes and also most efficient processes Reversible and Irreversible processes :- If  process is said to be a reversible processes If it can be reversed in direction following the same path as that of the forward process without leaving any change in the system and surrounding Note :- Ideal flow through a nozzle ,  diffuser etc. Will be considered as reversible.

Macroscopic approach in this approach the avg.  Molecular behavior is studied and individual behavior is disregarded. This approach is applied when the continue concept is solid Continuum is a   matter is treated as continuously distributed without in void present continuum can be considered if the mean free path is much smaller than the system dimension. Mean free path it is the avg.  Distance traveled by the molecules between two successive collisions. Microscopic approach this approach is applied when the matter become rare (Density is very less) hence the avg.  Property become meaningful in this approach we focus on individual molecules. It is used in space exploration. One of the methods is ratified gas flow theory.

Thermodynamics Equilibrium is the system is said to be said to be thermodynamics equilibrium if it satisfied the following equilibrium conditions. Thermal equilibrium Equality of temperature , mechanical  equilibrium Equality of forces, chemical equilibrium Chemical reaction potential should not be present , Phase equilibrium Mass of each phase remains constant with time .Pure substance :- A substance is said to be pure substance if it is of Homogeneous chemical composition throughout (P+ F = C + n ), P is a  No.  Of phase (solid, liquid, gas), C is a No.  Of chemical component, N is a No. Of non-composition variable. DOF degree of freedom DOF is the minimum no. Of independent intensive variables required to fix the state of the system. 

 Zeroth law of thermodynamics According to Zeroth law if a body ‘A’ is in thermal equilibrium with body ‘C’ and also body ‘B’ is in thermal equilibrium with body ‘c’ then body ‘A’ and body ‘B’ is in thermal equilibrium with each other In Zeroth law body ‘c’ acts as thermometer Zeroth law gives the concept of temperature measurement Hotness or coolness is the feeling associated with the rate of Heat transfer Temperature is a parameter which represents random energy per unit molecules. 

TYPES of thermometer Thermometers are based on finding thermometric property. Thermometric property is a property which helps in finding temperature for volume and length in mercury thermometer Temperature exactly show the physical condition of given fluid 1) Resistance Thermometer or Thermistor It is based on Wheatstone bridge principle and the Thermometric property is the resistance 2) Thermocouple It is based on see Beck effects acceleration to this effect of two metals are joint to form two different junction and they are maintain of different temperature then emf is generated which is directly properties to the temperature difference by measuring the emf the unknown temperature can be found Emf , voltage or current is the Thermometric property Peltier effects is opposite of see back effects and it is used for thermo- electric refrigeration 3) constant volume gas thermometer :- IV)  constant pressure gas thermometer Both cv and cp gas thermometer are called ideal gas thermometer because material of construction is ideal gas Ideal gas thermometer are independent of material of construction that is if the gas is an ideal gas it does not matter which gas it is.

It is more important subject as a gate point of view and also important in SSC JE exam near about 30 number of question asked in SSC JE exam. In gate exam number numerical basis question asked and also in je exam objective type question asked. in this subject contain thermodynamic law more numerical asked on this basis. Thermodynamics are used in the heat conversion area areas Mechanical Engineering Thermo-Science design engine and power strips, heating, ventilation and air conditioning (HVAC) systems, heat exchange, gas sink, radiator, refrigeration, insulation and others are used. i will provide important notes for gate and ssc je very soon.

STRENGTH OF MATERIALS ke bare me jankari


Elasticity = when an external force acts on a body, the body tends to undergo some deformation. If the external force is removed and the body returns to its original shape and size, then the body is known as elastic body. If the body comes in its original shape then it is called completely elastic body. Elastic limit marks the partial break down of elasticity beyond which removal of load result in a degree of permanent deformation. Steel, aluminum, and copper, concrete can be considered completely elastic within a certain range.

ENGINEERING MECHANICS lecture 1 ki jankari


               Mechanics this science is defined as a branch whose condition describes and predicts Body or body movement under powerful operation the engineering mechanism applies Principle for design, taking into consideration the principles of military effectiveness. Static Static’s are associated with the balance of the body. Hard body A strict body is defined as a certain amount of substance, the portion of which has been fixed The physical body is never completely related to each other, but it is quite rare Under the load's proceedings. If the deformation is negligible if compared to its size the body is called strict. Forced Persistent can be defined as any action that prompts someone to change the state of rest or movement. To whom it is applicable To define the full force, the required three numbers are called its S.

POWER PLANT ENGINEERING kya ha jankari exam point of view


Gas Turbine It is a mechanical device converts one form of energy into useful form of energy. Type of engine:-1} I C engine:- In the case of  IC engine the product of combination itself is the working fluid and produces output Compression and expansion takes place at Same location 2}E C engine :- In the case the case of EC engine the product of combustion are transferred their heat to the another working fluid and which it used for providing some useful output. Advantage of gas Turbine over IC engine Simple mechanism ,High speeds can developed due to the rotary engine ,Easy balancing, Compact that is weight to power ratio is less Disadvantage :-1}The comp.  Which is used in gas Turbine handling the gaseous phase of working fluid which is not negligible in comparison to the Turbine work, therefore the net workout put reduce and it's efficiency work, therefore the net workout put reduce and it's efficiency is less as that IC engine.2) high speed reduction gear are required as the value of centrifugal force are high. 3) High heat resistant material are required for the gas Turbine because these are subjected to higher temperature continuously for a long period of time. (Creep failures changes) 



Manufacturing process :-It is process of converting raw material into a finished product It is a process of value addition to the raw material Classification :-1) casting -- zero process ( casting ), 2) Forming - Additive process ( Rapid prototype ), 3) Fabrication process -- subtractive process, 4) material removal process -- subtractive process. Casting  :-It is process in which molten liquid metal will be allow to solidify in a pre defined mould cavity. ORE = RAW material of casting1) pattern 2) mounding sand  3) tools Mould box :-Two box, Three box Advantage 1) complex shape of object produce ,2) It is simple and leas expensive process ,3) Ductile and brittle material can be produced, 4) large size object can produce by casting only, Ex. Machine tool beds ,  engine blocks,  gear box housing ,  Road rollers. Limitations :- Poor surface finish due to liquid  metal is contact with grains of mounding sand Ra = 10.15 um Due to permeability of mounding bond (press different )  gas defects are more so casting is not used for domestic cylinder Bcs  of non - uniform condition. 1) casting objects are not having smooth surface finish 2) it is laborious and time consuming process 3) there is a possibility of gas defect in the casting 4) casting object are not having uniform mechanical properties due to non uniform cooling.



Material science:-A study of relationship between structure and properties of engineering material Microstructure:-microstructure is defined as the internal structure details of a material, which can be observed at high magnification under a microscope  Microstructure include, 1) Grain and grain boundaries 2) phase and phase Boundary 3) grain orientation luster Microscope us observed at magnification more then or equal to 100x Metallic sample are opaque - metallurgical micro-structure atom Transparent sample :- pathological microstructure examine (blood  and urine sample )  To change microstructure :- manufacturing process Properties are depend of phase change :- microstructure change Macrostructure :-It is defined as the external geometrical characteristics of an object which can observed by naked eye or under the microscope at lower magnification of the order of less than 100x Only to achieved Macro structure improvement welding ,  forming ,  machine.



MECHANISM AND MACHINE Simple mechanisms:-Kinematics link or element:-Each part of the machine which is relative motion with to some other part will be known as Kinematics link or element. It is necessary for the link to be a resistant body.  So that it is capable of transmitting power and motion from one element to the other element. TYPES of link:-1) Rigid link: - Deformation are negligible (microscopic)  E.g. Cams,  connecting Rod,  piston,  cylinder. 2) Flexible link: - Deformation are not negligible, but are in permissible limits, E. g.  Belt, rope, chain drive. 3) Fluid link: - when the power is transmitted due to fluid power. E.g.  Hydraulic breaks lift.



Automotive mechanical by Joseph heithes (For subject point of view and object queation) I. C.Engine by v. Gnesan ( For problem point of view) I.C.Engine by Mathur and sharma Thermodynamics :-It is the field of science which deals with energy possessed by gases and vapors,  It's conversion in terms of heat and work and it's relationship between various properties of system. System:-Reference to any space,  A matter or a group of Metter within a definite Boundary whether real or imaginary is defined as a system. Surrounding:-Any matter that is outside the boundary and affect the behavior of system is defined as surrounding. Shown the gas inside the piston cylinder arrangement is a system both Boundary B1 and B2. Cylinder is system for the boundary B2 and surrounding for the boundary B1 P, V, T = Are the fundamental properties of gas. Properties:-Property of a system is that quantity which belongs to the system.  And without which the system cannot exist. Thus P, V, Railway are known as the fundamental properties of system. Heat and work are not a property of system. Note- Heat is not a property of gas because without heat gas is existing. If volume is constant then work is zero so work is not property of gas.
