AFTER-MARKET ABS !! ARE THEY WORTH ??

ABS which simply means Anti-Locking Braking System prevents the rear or the front wheel or both in some case from locking up which if fails, ends in a disaster.

In technical terms,Anti-locking Braking System, is a complex technology in a motorcycle or a car that can help reduce the speed or stop the vehicle in an emergency situation without locking either of the two wheels or even all the four in case of cars. This is achieved by using speed sensors that is attached to the wheels that continuously monitor the wheel rotation speed and sends the data to the braking ECU which is in turn connected to the hydraulic unit that adjusts the hydraulic pressure of the brake fluid inside accordingly. In an emergency braking situation which is otherwise panic braking, one can be confident that the wheels wouldn’t lock up giving the rider a taste of the tarmac.

Can ABS System Purchased separately (After-market ABS)?

The answer is YES. But there are certain hitches in that too! You’ll have to figure out a way to calibrate the aftermarket ABS to your specific car/motorcycle. You must also understand that automakers spend thousands of hours testing and calibrating a car/motorcycle fitted with ABS, in order to fine-tune its working in real-world conditions. Obviously, this isn’t something that’s feasible for most owners. This is also a reason why after-market ABS systems, though available, are unpopular. Also after-market ABS are costly for example, Bosch makes an aftermarket ABS that costs a whopping Rs. 6 lakhs! 

It’s better to buy a motorcycle that has a factory fitted ABS system which would have been tested rigorously by the motorcycle manufacturer as an integrated part of the motorcycle itself.

WHY MODERN ENGINES USE FORGED PISTON? CHECK OUT THE ANSWER !!

Now-a-days forged pistons are used by most of high end vehicles.The main characteristic that makes forged pistons excel in high performance applications is strength and durability. 

The high silicon content of cast pistons makes them brittle compared to forged pistons. Silicon gives the metal lubricity and is mixed in the alloy to limit heat expansion. This is primarily the reason why cast pistons require careful handling. 

Mild shock applied to it may cause the material to break. The process of forging compresses the molecules inside the alloy, which results in a denser surface area compared to a cast piston.

The Difference:

The difference between a normal or cast piston and a forged piston is the manufacturing technique. Traditional cast pistons are considered good enough by most engine manufactures when it comes to stock setups, and suffer no drawback in terms of compression and service life. The cast piston is most common on all mass-produced engines, because the casting process of making this type of piston presents a low cost opportunity to the manufacturer.

Forged pistons employ a single lump of billet alloy which is stamped by the use of a die. The shape of the die determines the size and shape of the piston.Forged pistons are also easy to manufacture as there is no need for big, heavy and expensive casting equipment as employed in the manufacture of cast pistons.

How Air Bags Work ?

Air Bags:-

An airbag is a type of vehicle safety device and is an occupant restraint system. The airbag module is designed to inflate extremely rapidly then quickly deflate during a collision or impact with a surface or a rapid sudden deceleration. 

The purpose of the airbag is to provide the occupants a soft cushioning and restraint during a crash event to prevent any impact or impact-caused injuries between the flailing occupant and the interior of the vehicle. The airbag provides an energy absorbing surface between the vehicle's occupant and a steering wheel, instrumental panel, A-B-C- structural body frame pillars, headliner and windshield/windscreen.

There are three parts to an airbag that help to accomplish this feature:

>The bag itself is made of a thin, nylon fabric, which is folded into the steering wheel or dashboard or, more recently, the seat or door.

>The sensor is the device that tells the bag to inflate. Inflation happens when there is a collision force equal to running into a brick wall at 10 to 15 miles per hour (16 to 24 km per hour). A mechanical switch is flipped when there is a mass shift that closes an electrical contact, telling the sensors that a crash has occurred. The sensors receive information from an accelerometer built into a microchip.

>The airbag's inflation system reacts sodium azide (NaN3) with potassium nitrate (KNO3) to produce nitrogen gas. Hot blasts of the nitrogen inflate the airbag.
