Electronic Brake Force Distribution

Electronic Brake Force Distribution

“Electronic brake force distribution (EBD or EBFD) or electronic brake force limitation (EBL) is an automobile brake technology that automatically varies the amount of force applied to each of a vehicle's wheels, based on road conditions, speed, loading, etc. always coupled with anti-lock braking systems (ABS).” 

EBD can apply more or less braking pressure to each wheel in order to maximize stopping power whilst maintaining vehicular control.

Components of EBD

1. Speed Sensor: 

The speed sensor not only calculates the speed of the car, but the speed of the engine also (RPM). One of the scenarios can be that the speed of the wheel might not be the same as the speed of the car. Such a situation can lead to the wheel(s) skidding. The speed sensors calculate the slip ratio and relay it to ECU.

2. Electronic Control Unit: 

It is a small chip which collects the data from the speed sensors in each wheel and uses the data to calculate the slip ratio (difference between the speed of the car and the rotation of the tyre). Once the slip ratio is determined, it makes use of the brake force modulators to keep the slip ratio within limits. 

3. Brake Force Modulators: 

It is the job of these modulators to pump brake fluid into the brake lines and activate the brake cylinders. The brake force applied on each wheel can be modulated.

Working of EBD

Sensors that send signals to the brake force distributor from the anti-lock system. Information about the rotation of each wheel is recorded individually. 
The Acceleration / deceleration sensor, which refers to ABS. It is mounted in the wheel hubs of the car. The Valves that are part of the pressure modulator. The electronic unit which is common both for the braking system and for its “expansion”. He receives information about the speed of rotation of the wheels. Processes it. Activates only those valves of the brake system that are needed.
Hydraulic unit which is part of ABS. It changes the brake forces on the wheels and axles of the car distributes them correctly. Indicator lamp, which warns of problems in the active (brake) security system. Independently to solve the problem is strictly not recommended to operate a defective vehicle – too.
Advantages of EBD

1. Greatly reduce the possibility of brake lock up.
2. Provide better chance of steering.
3. Highly adaptable to every surface.
4. Greatly reduces the possibility of vehicle skidding.
5. Faster reactions to situations because of completely electronic & computer controlled.

Disadvantages of EBD

1. Expensive repairs & high cost of operation.
2. Require regular check ups & maintenance of sensors, valves and brake fluid.
3. Require complete overhaul on damage of few parts.
4. Delicate system, easy to harm and damage.

Centrifugal Pump

Image
Centrifugal Pump "Centrifugal pump  is a hydraulic machine which converts mechanical energy into hydraulic energy (i.e. pressure energy) by the use of centrifugal force acting on the fluid. " A centrifugal pump is the simplest machine which is used in various industries as well as in many daily applications to transfer fluid from lower head to higher head.  Centrifugal pumps are mostly used in chemical industries for easily transfer viscous fluids.   Also, it is less expensive than other pumping devices. In short, it is an excellent machine with efficient working in variety of applications. History of Centrifugal Pump- 1475- Italian engineer Francesco di Giorgio Martini designated mud lifting machine as a centrifugal pump. 1687- Denis Papin developed the first true  centrifugal pump  which was one with straight vanes that was used for drainage.  1851- John Appold, who was a British inventor, developed the first curved vane  centrifugal pump

Vapour Compression Refrigeration System

Vapour Compression Refrigeration System Vapour-compression refrigeration  or  vapor-compression refrigeration system  ( VCRS )  in which the  refrigerant  undergoes  phase changes , is one of the many  refrigeration cycles  and is the most widely used method for  air-conditioning  of buildings and automobiles. Vapor-compression uses a circulating liquid  refrigerant  as the medium which absorbs and removes heat from the space to be cooled and subsequently rejects that heat elsewhere. History:- 1805- The American inventor  Oliver Evans  described a closed vapor-compression refrigeration cycle for the production of ice by ether under vacuum. 1834-   American Great Britain,  Jacob Perkins , built the first working vapor-compression refrigeration system in the world. 1842-  American physician,  John Gorrie  who built a working prototype, but it was a commercial failure. 1850- American engineer  Alexander Twining  took out a British patent for a vapor compress

TURBOFAN ENGINE

TURBOFAN ENGINE The turbofan engine is a combination of the turbo prop and the turbojet engines combining the advantages of both. The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the turbo portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the fan, a ducted fan that uses the mechanical energy from the gas turbine to accelerate air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components.  In the 1950s, Rolls-Royce introduced the first turbofan in the world, namely, RB.80 Conway. Classification 1. According to Fan Location (a) Forward Fan Turbofan Engine (b) AFT Fan Turbofan Engine 2.
