Noken as BALAP MOTOR

ve so often you read and understand how a 4 stroke engine on a motorcycle to work, you certainly know the part called the valve / valve, which allows him a mixture of air / fuel into the engine penetrated or ejected out into the exhaust. Noken using the bulge (called Nok) to compress the valve to open when Noken spinning - pear valve and then works to restore the valve to the closed position. This is a very important performance! Have the most impact on the output power / performance of the engine at different speeds.

Here, we will learn to understand how Noken As affects the performance of a machine. So when you want to develop your racing machine to a higher level, be it a Road Race, Drag Race, Cross, or simply want to improve the performance of your bike for daily use on the highway, you know that the RAT Motorsport Noken produce the highest possible performance, provide superior service, and always do the development of technology.

So let's start from scratch!

Lockdown of a camshaft is Noken or ridge / Nok / Lobe has. When Noken spins, this bulge punching valve to open and close in accordance with the movement of the piston. This is proof that there is a direct relationship between the shape of a Noken and how to display the engine performance at different speed ranges.

To understand this case, imagine we are running the engine very slowly - 10 or 20 RPM - so that the piston has a few seconds to complete the cycle. But it is impossible to run this machine as slow as normal, but just imagine if we could. With speeds as low as this, we want a bulge shape Noken as:

Instantly the piston moves down on the steps of suction, the intake valve is open. And closes when the piston in the TMB.
Exhaust valve opens when the piston TMB at the end of the expansion step, and close the flue when the final step.
This setting is suitable for a machine that moves very slowly. But what happens when you increase RPM? Let's find out!

When you raise the RPM to be only 4.000 rpm, the valve open and closed 2,000 times every minute, or 33 times every second. Yet we still think the RPM is low is not it? For us fans speeds, to increase the adrenaline usually we like menggeber to over 8.000 RPM, and imagine that the valve opens and closes more than 60 times each second! Even blink our eyes alone can not be that fast. Then how can meet racing engines intake air / fuel into the engine, and discard the rest of the combustion gases at high speeds of up to 12.000 RPM engine screamed more?! Wow, at this speed, the piston moves up and down in the cylinder so fast, also a mixture of air / fuel penetrated so rapidly into the cylinder.

When the intake valve opens and the piston start the suction step, a mixture of air / fuel in the port began to accelerate into the cylinder. Immediately below the piston reaches the suction step, a mixture of air / fuel is moving at high speed. If we just close the intake valve at this point, the overall air / fuel stops and does not enter the cylinder. By allowing the valve to remain open a little longer, inertia (momentum) velocity of gas mixture of air / fuel intake will continue to push this into the cylinder while the piston has started initial compression step. We also want the valve wide open at high speeds - this parameter is called Lift Valve, which is set from profiles Noken bulge.

Therefore, every detail of a particular specification, use the tuner to design Noken specifically for the machine and the purpose built machine. How the lack of a machine, can be driven from the heart, regulating pulse and rhythm of the pace of an engine power of Noken course. Grinding Noken far more effective and efficient way to regulate the rhythm of duration and lift as long as it is done properly by an experienced tuner in its field.

Noken EACH WILL ONLY PERFECT IN A RANGE OF SPEED OF CERTAIN MACHINES! At a certain energy range, the engine will not produce the performance on its full potential. Of course not optimal to use the default standard Noken motor when the engine has been modified in such a way as to be driven on a racing competition. As we can not apply Noken with specifications for competition racing on a standard engine that is used daily, in addition to wasteful consumption of fuel is also potentially damage the engine. Of Noken as Street Performance is playing in 270 degrees and lobe lift is not too far from the original congenital motor, ideal for standard engines or with minimal changes, slightly above mengatrol power without loss of torque in the run-down so that fuel consumption can still be tolerated.

RAT MOTORSPORT, never forget that performance is not simply defined in the theorem - both on the track or on the road. We spend thousands of hours devoted to personal, as well as racing team, to continue to develop products that we produce Superior Performance and durability of the strongest.
