KNOW THE MEANING OF A/F ON NUMBER PLATE IN NEW VEHICLES !!!!


A/F stands for Applied For. This was a previous notation on the newly bought number plates of the vehicles. Every vehicle needs to be registered under the Motor Vehicle Act 1989.

Yes,it's illegal to drive with an A/F plate in India and can attract heavy fine and even car can be bonded. Every car that rolls off the showroom now gets either a temporary number or a permanent number according to the state.

The Central Motor Vehicles Rules (CMVR) do not allow driving a vehicle without registration. To drive a vehicle even with the `A/F' (Applied For) status is an offence. "It is a misconception that people can drive with an A/F tag,"

KNOW WHAT WILL HAPPEN IF YOU BLOCK YOUR ENGINE EXHAUST !!

If someone blocked it successfully the engine would stop because it can't expel the exhaust gas on the second stroke of the piston.Damage to the engine would be highly unlikely.The engine is basically a big air pump. Air is drawn into the engine through the air filter and the fueling system by the movement of the pistons. As the piston moves down, valves open on the air filter side allowing air to fill the piston. As the piston move back up after compression and ignition, the valves on the exhaust side open allowing the air to be pumped to the exhaust system. If the exhaust system won’t allow any air out, the engine won’t run as it won’t be able to draw air and fuel into the engine. Air has to have somewhere to go for it to flow.


DIFFERENCE BETWEEN BRAKE FADE AND BRAKE DRAG EXPLAINED !!

Brake fade-Since during braking of a vehicle a large amount of heat is generated and the brakes drums and discs are forced to absorb this.Hence brake fade describes a condition where heat is generated at a faster rate than they are capable of dissipating into the surrounding.

Since the brake pad is fixed with some adhesive material hence when such large temperatures are achieved during braking this adhesive material starts to vapourise and forms a layer between the disc rotor and brake pad there by decreasing the braking force(as the layer formed is compressible)which in turn reduces the braking efficiency of the vehicle.Also the friction material overheats and the coefficient of friction drops off significantly which also reduces the braking ability of brakes.

Brake drag-It is the rolling drag that brakes incur at elevated temperatures.This problem can be caused by several occurrences from failing of master cylinder to misalignment of brake calipers.Generally brake drag is caused due to incomplete brake shoe release.
Or by broken or weak springs on drum brakes.Or may be due to corroded or jammed caliper piston.Also brake drums that have defective linig material,out of round(elliptical),have clogged lines or hoses or loose anchor pins can also cause brakes to drag.

TWO MOTORBIKES WITH SAME CUBIC CAPACITY BUT DIFFERENT MILEAGE !!! WHY ??


You might have noticed that motorbikes having same cubic capacity gives different mileage. For Example,Bajaj Platina has cubic capacity of 100 CC and it gives mileage of 104 kmpl,on the other hand Hero Splendor is also having same cubic capacity but it gives the mileage of 81kmpl.

It is mainly because the bikes like Platina has been made keeping in mind mileage.Parts are light to keep bike weight low.Carburetor is tuned to extract mileage though it puts a strain on engine which you can judge from harsh engine note.If you race it will shudder as it puts strain on engine.Also it gives Low torque, low BHP, and leaner air fuel mixture. Tyres are slim for less friction with road.All this saves you petrol but at a high maintenance cost & low resale value.High maintenance cost can be curtailed with regular servicing but if you give less petrol to engine then wear & tear will be more anyway.

NITRIDING PROCESS EXPLAINED !!

Nitriding is the diffusion of nitrogen into the surface of special alloy steel to give a hard surface and soft core without the need for further treatment. Processing is generally carried out in the temperature range 470ºC to 530ºC in an atmosphere of ammonia, although other processing media can be used, such as salt baths and plasma.


Nitriding is only carried out on special alloy steels containing chromium or aluminium. It is the reaction of the nitrogen with these alloy elements that causes the hardening, so that, unlike carburising and carbonitridingquenching is not required after processing. The nascent nitrogen is obtained from an atmosphere of ammonia gas, which at 500°C dissociates into its constituent elements, nitrogen and hydrogen. The nitrogen, which is in solution in the iron, diffuses inward and forms aluminium or chromium nitrides producing high hardness in the surface of the nitrided component. A layer of iron nitride and alloy nitrides forms on the surface (the "white layer''). Since this is brittle it is normally removed from bearing surfaces before service. As with carburising the case depth is time and temperature dependent.

Nitriding produces advantages in addition to a freedom from distortion, which is due to the low treatment temperature and the fact that quenching is not required.


Materials that can be nitrided include low carbon steels, which will develop file hardness, alloy steels such as 4130, 4140, 4340 and Nitralloy 135M which are the most common nitriding steels and special application steels including, mold steels (P-20), air hardening tool steels (A-2 and D-2), hot work and shock steels (H-13 and S-7), high speed steels (M-2, M-4 and M-42), and stainless steels (304, 316, and 17-4 PH).

A prime application for nitriding is plastic injection mold components, including screws, tips and barrels. The hardness of the nitrided layer is especially useful in reducing wear from plastic molding, particularly when abrasive plastics like glass filled polymers are extruded.

18 CYLINDERS !!! 2000 HORSEPOWER !! 4600 CC !!! WATCH THIS GIANT IN ACTION THROUGH CUTAWAY !!


The R-2800 Double Wasp is an American made, 18-cylinder radial engine which was the most powerful engine of its type in the world during that time. Designed in early 1930s and first tested in 1937, it is still considered one of the best piston engines ever designed. Arriving right before World War II, the original 2,000 horsepower it generated made it ideal for placement in war planes.

WHICH ENGINE OIL IS BEST SUITED FOR YOUR VEHICLE? SYNTHETIC OR MINERAL?? CHECK OUT THE ANSWER !!!


There are 3 types of motor oil or engine oil used for the lubrication of engine. Engine oil is the most vital and essential one for an engine to function properly. The three types in general are mineral oil - derived from petroleum based products, fully synthetic - completely artificial and synthesized in labs. semi-synthetic- a blend of synthetic and mineral oil in definite proportions. 


Generally an engine oil has many benefits like lubricating the engine, carries away the heat produced during operation, reduces friction, wear and tear of the internal components and keeping the engine clean, free from sludge combustion and carbon deposits.

Synthetic oil is not only refined but also distilled, purified and broken down into its basic molecules. This process not only removes more impurities from the crude oil but also enables individual molecules in the oil to be tailored to the demands of modern engines. These customized molecules provide higher levels of protection and performance than conventional oils. A fully synthetic motor oil or engine oil is widely used in high performance motorcycles and cars. The main advantage of using a fully synthetic engine oil is that it maintains its stability and viscosity (thickness) even at very high temperatures. Hence it protects engine and its components during high speeds and long run. Superbikes in the world like Yamaha R1, Suzuki Hayabusa and MotoGp racing bikes, high performance cars use fully synthetic engine oils.
Fully synthetic engine oils provides better engine protection than any other type of motor oils. The advantages of using a fully synthetic oil is that it provides better engine performance, less engine heating, improved acceleration and more interval of oil change. It lasts longer than mineral and part synthetic oils.
But all this advanced technology doesn't come cheap. A synthetic oil change can cost over twice as much as conventional oil.but is it worth it beyond its obvious better performance characteristics?

This is not exactly a straight yes or no answer to go along with this question as there are several variables to consider, but in general, most experts would agree that synthetic is (for now) the lesser of the two evils.
Their logic stems from the fact that while conventional oil is evil because it is derived from petroleum, synthetics are unfortunately formed by chemicals that are no less harmful to the environment... but there is a difference here. Synthetics can last as much as three times longer than conventional oil.
With todays technology, synthetics are cleaner and meaner (just not necessarily any greener). Their composition is much cleaner, because it is derived in a laboratory rather than nature, and it has been proven to have a lower volatility and therefore not vaporize out the exhaust as quickly.
If you want to be on the safe side, you can follow what your manufacturer recommends as far as oil goes. In general more performance oriented vehicles require synthetic because of the high heat that builds in these engines, whereas conventional engines don't require anything special.
