Suspension System of an Automobile

Suspension System Suspension system is the basically the term given to the system of springs, shock absorbers and linkages that connects a vehicle to its wheels and supports the vehicle. This is done to isolate the vehicle body from road shocks that maybe in the form of bounce, pitch and roll and caused due to the bumps, potholes and other road irregularities.Whenever  Tyre of the vehicle hits an obstruction on the road it experiences a reaction force and the suspension system tries to reduce this force. In short, all the parts and components that isolates the vehicle from road shocks are collectively known as suspension system. The main objective of the suspension system is as followed below:   It supports the weight of the vehicle    Provides a smoother ride for passengers   Protects the vehicle from damage  Keeps the wheels firmly pressed to the ground for better traction   It isolates the vehicle from road shocks and vibrations Main Components of a suspension s

Magnetic Ride Suspension

Magnetic Ride Suspension Magnetic Ride Suspension is a type of Active Suspension system that actively controls the vertical movement of the wheels with respect to the vehicle's body. It uses a kind of shock absorber, which also known as MR damper, in which the liquid contains a suspension of metal particles and the conventional fluid which on the application of magnetic field that turn on the signals provided by the sensors.  How is works ? The piston have a number of channels through which the liquids flow in normal condition but whenever there is any sharp turn or any other kind of irregularity on the road surface which bring the role of suspension system in action, then sensors send the signals and the electromagnetic field is generated which aligns all the metal particles in horizontal direction which as a result creates difficulty for the piston to move and provides stiffness which results in better handling as well as control and contact with the surface improving t

Octane Number and Cetane Number.

Automotive Fuels As we all know that the major fuels that are used in the Automobiles are Petrol in SI engines and Diesel in CI engines, apart from these there is CNG (compressed natural gas) that is also used as a fuel and the Electric Vehicles, but here we will discuss only about the Petrol/gasoline and the Diesel fuel. The Automotive fuel which is used for the purpose of the combustion inside the engine have ratings  or we can say the quality standards on the basis of which we can easily identify the quality of fuel which will be discussed below in details: Rating of Engine Fuel:     In case of S.I (spark ignition) or petrol/gasoline engines, the quality or rating of fuel i.e petrol is  based on the Octane Number, whereas in case of CI (Compressed Ignition) or Diesel engines the quality of fuel (diesel) is determined by the Cetane number. What is Octane Number? It is an expression which indicates the ability of the fuel to resist detonation in SI engines. It is

COMBUSTION IN IC ENGINES.

Image
Hey guys in this post we will talk about the fuel behaviour and the combustion process in the IC (internal combustion) engines and we will also look at the various important terms that each and every automotive enthusiast should know about the combustion process i n IC engines. What is Combustion? It is the rapid and high temperature oxidation of fuel with liberation of fuel energy. The requirements for initiating the combustion process are: ·        Combustible air-fuel mixture ·        Means for starting the combustion and formation, stabilisation and propagation of flame inside the combustion chamber of the engine. Some of the very important terms: Ignition Lag or Delay period - It is the first time interval between the instant of spark and the instant when there is noticeable rise in the pressure due to combustion.  Self-ignition temperature - The temperature at which fuel will ignite itself without flame or in absence of flame i.e we don'

TWIN CHARGING AND FUTURE OF FORCED INDUCTION SYSTEMS

In the previous post we told you about the Forced Induction Devices and later We talk about Turbochargers and Superchargers. Now what we see is that sometimes you would find yourself unable to decide about which is better:                 1. Turbocharging the engine?                                      or              2. Supercharging the engine?        Turbocharging will be more efficient but not as fun as the Supercharger.                                   Therefore :           SUPERCHARGER+TURBOCHARGER = TWINCHARGER                                           Twincharger A twincharger is the perfect example of "Best of both Worlds". Twincharging an engine in simple words mean adding both, a Turbocharger as well as Supercharger into the engine. How does it work? The mechanism of a twincharger is not complicated at all. As a matter of fact , it follows the basic fundamental principles of turbocharging and Supercharging. What happens is that

Turbochargers Vs. Superchargers.

Introduction We are all aware of the naturally aspirated engines that we have been seeing since the starting of automotive industry but in the later times came the forced induction systems which brought a completely new power and changed the scenario, as forced induction system increased the performance as well as the efficiency of the internal combustion engines. The Turbocharger and supercharger both are different type of forced induction systems and also both are the best examples of forced induction system. The mechanism of the Turbocharger and Supercharger is quite different but they both use process of compression of air into the engine. The use of Turbocharger and Supercharger is nothing but to increase the performance and efficiency (in case of the turbocharger). What is a Turbocharger? It is a turbine driven Forced Induction device. Turbocharger is being used in about 95% of the diesel vehicles today and is the most popular Forced Induction system. Pop
