What is Casting Defects? It is an unwanted irregularities that appear in the casting during metal casting process. There is various reason or sources which is responsible for the defects in the cast metal. Here in this section we will discuss all the major types of casting defects. Some of the defects produced may be …

What is Boyle’s Law? This law was established by Robert Boyle in 1662. At constant temperature, the absolute pressure of a given mass of a perfect gas is inversely proportional to its volume. Have you understand something from this? If not than let’s we understand what this statement implies. It means that if we have …

Brakes are very crucial for stopping a vehicle. Without brakes, it is impossible to drive a car or any vehicle. Brakes are of different types and according to the requirement, the types of brakes are chosen for the application. Here we will discuss Disc brake – its main components, working, advantages, and disadvantages with the …
If someone ask you a question that can you drive your vehicle without brakes? Then what will be your answer, obviously No. Driving a vehicle without brakes is impossible. Brakes are crucial for stopping a vehicle and driving safely on the road. The use of a proper braking system enhances the handling of the vehicle …
What is a Perfect Gas? A perfect gas or an ideal gas is a state of a substance, whose evaporation from the liquid state is completed and which obeys all the gas laws strictly under all conditions of pressure and temperature. In reality there is no ideal or perfect gas which obeys all the law …

Adiabatic process is a process in which there is no exchange of heat takes place from the working substance to the surrounding during its expansion or compression. This is possible when the working system is made thermally insulated, that is no heat can leave or enters it during the process. So we can say that …
The diesel cycle was invented by Rudolph Diesel in 1893. He put forward an idea by which we can attain higher thermal efficiency, with a high compression ratio. All diesel engine works on this cycle. Diesel is used as fuel in this cycle as it can be compressed at a higher compression ratio. It is …
The Otto cycle was given by Dr. Nikolaus August Otto. It is a gas power cycle that is used in spark ignition engine (i.e. petrol engines) for its working. The entire modern petrol engine works on Otto cycle. It consists of four processes, Two isentropic (reversible adiabatic) processes and two isochoric (constant volume) processes. It …

What is Spark Ignition Engine? It is an internal combustion engine in which the ignition of the air-fuel mixture takes place by the spark. The spark is generated with the help of a spark plug. Since in this engine, the spark is responsible for the ignition of the fuel, it is named as spark ignition …
