There is a lot of misunderstandings of what ABS is and what it does and more importantly, what it doesn't do. Let us discuss it with a listing of what I think are 3 facts and myths surrounding ABS and why it could save your life someday . ABS is Anti Brake-Locking System As the name implies, it prevents brake locks - the heart-stopping panicking moments of wheel locking up if we apply brake too suddenly. Brakes? Kinda are more important than the engine themselves. This can cause awesome skids which could be attractive if you are a stunt rider and are stunnting. Whereas, if you are trying to stop because you are riding head-on onto oncoming traffic; I have no clue why you would be; but that wouldn't spell good for you, so stopping the biking when you want it to stop is critical for riding. ABS is any system that prevents the wheel lock, by releasing the pressure on the brake disc, if it senses a wheel lock. This is done using motion sensors, which in turn...

How to Increase Engine Power - Keeping CC Constant

By


jawadhu hills


Easy Question to ask with the answer being- by burning more fuel.

But the complication comes into picture when you compare two different engines of the same CC, can we infinitely throw in more fuel to extract more power?

Let us take two different engines of the same manufacturer and compare them to answer the question.



So how one produces 30% more power while being the same CC with only 500 rises in RPM?

Let us look at another figure:



Now, this is only 17% rise in torque curves with 1500 rise in RPM.

So how does engine produce power? The air-fuel mixture is thrown into the cylinder and ignited.

This combustion creates expansive pressure that pushes piston which turns the camshaft.

Longer the stroke of the piston - more torque generated
Shorter the stroke, More frequent the stroke becomes (higher RPM) - more power.

So to increase the power output of an engine, it is important to increase the RPM at which the engine runs.

How to increase the RPM, hence the Power?

  1. We can make the fuel-air ratio to be richer: but if we go past the Stoichiometric ratio, it will produce lesser power - to do this, we will require a free flow air filter, tune the engine fuel richness and also ensure that the exhaust has enough back pressure.
  2. We can increase the compression ratio: but we should also increase the piston and engine quality to be able to withstand the increase combustion pressure - This is not adjustable for all bikes on the go, and hence not done by consumers.
  3. We can make the engine components to be lightweight - which will decrease the momentum they carry which increases the RPM - Same reason as above, not done by consumers.
  4. We can increase the lubrication by adding engine oil that is better - Easiest to be done; whereas engine must be compatible with fully synthetic engine oil - which if is the case, directly use Motul 300V.

   
This explains why Street Rossi change their muffler first and claim to have increased bhp
    - which isn't true because they usually don't upgrade the air intake.
And why does R15 produce more power than the FZ15?
- simply because the engine is engineered to be able to run at a higher RPM while making shorter strokes whereas the latter runs at lower RPM but making longer strokes.

The above-mentioned methods of increasing engine power aren't exhaustive and only a guide towards how power increase happens.

Ergo, Rise

By
I fondly remember the first time I saw a motorcycle, the first time the memory of a machine on two wheels got etched into my mind. It was a moped and I was 2 years old, ergo, it seemed like a big machine that is capable of pulling an entire family. Utterly ignorant of its complexity, what stuck in my mind was that it was a useful addition. Fast-forwarding by several years, I remember being dropped at the school by my uncle or being taken out for ice cream. We as a family, never had a motorized vehicle as dad doesn't drive or ride so motorcycling became missing for the majority of my life. However, around high school, dad gifted me my first bicycle and with that, the range of my 'territory' increased! I remember the first time I crossed the Adyar bridge and went to Mylapore to have coffee without telling my parents. A mere distance of 5 kilometres which was previously unreachable became reachable with just a bit of courage and planning. Did your crush live a few kilometres a...

What is Compression Ratio...? and how is it related to High Octane Gas...?

By
The internet has a lot of information regarding what Compresssion Ratio means for engines. But there are very few articles that mean much to motorcycle engines and about how the CR influences the characteristic of a motorcycle. In theoretical terms, the compression ratio is the ratio of volume between the top-dead-center and bottom-dead-center.. Here are the CR for some common Indian Motorcycles: Model Wet Weight in KG Compresion Ratio KTM D390 163 12.8:1 R15 136 10.4:1 CBR 250 164 10.7:1 RE Classic 350 187 8.5:1 Avenger Cruise 155 9.5:1 What this number actually signifies is how much the air-fuel mixture gets compressed to before being ignited . That is, how much pressure would the combustion produce inside the engine. To Simplify:     More the CR, more the internal combustion pressure     More the CR, more the heat produced during combustion  ...

The Will of the Unwilling - Suicide Note of a Dying Breed?

By
The differences in the motorcycle brands are converging and it will only converge more onto a point of superposition.  Rewriting that and replacing "motorcycle brands" with "people", the differences in the people are converging and it will only converge more onto a point of superposition.  It is not very difficult to see that total convergence is bad irrespective of entity. Michael Crichton, with all his wisdom, wrote that internet is a fall for the human kind. Because the thoughts and ideas that were isolated yielded aggressive and diverse progress. With the advent of internet, it has bought thoughts and ideas closer and they have stopped being unique. Ergo, the progress is linear and no longer diverse. The same is happening to us right now. As people and as motorcycle brands. Do you support feminism or not? It has become black or white. There is no longer a grey area. Such polarized classification will only yield friends or enemies. It will stop being possible for...
