Today we will discuss about main parameters used to test a engine performance. Engine testing is very important part of engine design. The engine performance indicates by the term efficiency. For the testing basis, five major efficiencies are used which we have discussed in the last post. If you have not read the last article first …
The engine performance is indicated by the term efficiency. Today we will discuss about diesel engine efficiency and petrol engine efficiency. In auto industries, five engine efficiencies are used to check an engine performance. These efficiencies are Indicated thermal efficiency, Brake thermal efficiency, Mechanical efficiency, Volumetric efficiency and Relative efficiency. These all are that parameters which …
We all know about air conditioning system. The automotive air conditioning system is also works on the reverse Brayton or Rankine cycle. As like all air conditioning system the aim of automotive air conditioning is to control the temperature and humidity of the atmospheric air and circulate the same in the automobile. The automotive air conditioning system …

Today we will discuss about continuous variable transmission. We also discuss about advantages and disadvantages of CVT transmission. Till now we know that we use gear box to change the torque according to the driving requirement. For this we have four to five gear ratio which we shift and change the gear. But CVT is an …

Today we are going to discuss about ABS technology used in automobile. If you use car, you have heard this term many time in your life. When we go for purchase a new car and the salesman told us this car is with new safety feature ABS. That time we are surprised what is ABS? …
Today we will discuss about hydraulic brake system. It is one of the most useful braking system. Most of the cars today use hydraulically operated foot brakes on all the four wheels with an additional hand brake mechanically operated on the rear wheels. This type of brake is more reliable and easy to handle. Today …
Today we will learn about air brake system. Air braking system is one of a high power braking system. It is commonly used on heavy vehicles, like trucks, buses, etc. In my previous post we have discussed about types of brakes and we know that there are only two types of braking system. The first …
Today we will discuss about types of brakes. The brake is one of the most important controlling component of vehicle. We have heard about drum brake and disk brake. Drum brake is widely used in the automobile. The brakes are required for stop the vehicle within the smallest possible distance or to slow down the …
Today we discuss about automatic transmission. We all use bikes and cars. We all know that we need transmission box or gear box to change the torque according to driving condition. In earlier we used manual gear box in which there is a hand or foot operated lever and clutch through witch we shift the …

The shock absorber is provided provide the damping of the spring to prevent excessive flexing. In the leaf spring the friction between the leaves provide the damping effect but sometimes it is not sufficient so we used shock absorbers. In case of helical springs the whole damping effect is provided by the shock absorber. The …
