BUSI PULSTAR




Busi Pulstar, busi dengan teknologi terbaru, mampu menghasilkan 1 juta watt selama 2 nano detik, sehingga mampu membakar secara sempurna seluruh bahan bakar di dalam ruang pembakaran, dan terlalu singkat untuk menjadikan blok mesin ataupun komponen mesin lainnya menanggung panas yang berlebihan. Selain itu, pembakaran yang lebih cepat dapat meningkatkan tekanan silinder hingga 10%, sehingga akhirnya juga meningkatkan tenaga mesin dan menghemat BBM.
Busi Pulstar , mempunyai prinsip kerja yang berbeda jika dibandingkan dengan busi biasa. Pada busi biasa, banyak energi yang terbuang menjadi panas selama proses ionisasi elektrodenya. Hal tersebut berarti bahwa loncatan bunga api tidak akan terbentuk selama tegangan di antara ujung elektrodenya tidak mencukupi untuk membuat sebuah percikan dan akibatnya banyak energi yang terbuang. Busi Pulstar bekerja dengan mengumpulkan energinya di dalam sebuah resistor. Jika tegangan yang akan digunakan untuk membuat bunga api mencukupi, maka energi tersebut akan melewati resistor dan seketika muncul mejadi percikan api di antara ujung elektrodenya.

Busi Pulstar, dapat meningkatkan torsi hingga 12 %, meningkatkan tenaga hingga menghemat BBM hingga 11 %, mengurangi waktu akselerasi hingga 5 %, juga mengurangi emisi gas buang.
Busi Pulstar adalah langkah pertama untuk menambah torsi dan tenaga mobil bensin anda, sebelum anda melakukan modifikasi apapun.







Pulstar Pulse Plug
The company says the high power of the Pulstar™ will not damage an engine because the high power event lasts only for 2 microseconds (billionths of a second). This very brief moment is enough to ignite the fuel in the cylinder, but too brief to overheat the combustion chamber or metal engine components. So it will neither harm your engine nor void your manufacturer's warranty.
"Pulstar™ looks like a spark plug because it was designed to fit into the same hole in your engine. But, internally, Pulstar™ is very different, incorporating a pulse circuit no other plug has. This is why we call Pulstar™ a "pulse plug" and not a spark plug."
How it Works
Pulse plugs incorporate a pulse circuit, which stores incoming electrical energy from the ignition system and releases the stored energy in a powerful pulse of power. Instead of 50 watts of peak power typical of all spark plugs, pulse plugs deliver up to 1 million watts of peak power.
Spark plugs waste energy by heating ignition components before the spark occurs. Pulse plugs capture wasted energy with a pulse circuit and then release the captured energy into and eyond the spark gap. When the ignition power overcomes the resistance in the spark gap, the pulse circuit discharges all of its accumulated power - 1 million watts - in 2 billionths of a second!
Why It Doesn't Work
It's great to throw out clever sounding ideas that appear to solve a problem, but without understanding the fundamentals behind the problem, how can one determine if the suggested solution is applicable? These plugs rely on two fundamental 'problems': 1. Gasoline has extra energy in it that is lost because it is not fully burned, and 2. An 'impulse' plug can solve this problem by using more power to burn the gasoline more wholly.
What's the problem here? It's three fold. -The amount of energy that exists in 'unburned gasoline' in a conventional automobile under the most common of conditions is almost nonexistent. -The gasoline that is unburned is recaptured by a car's exhaust gas recirculation system and is sent back through the combustion chamber to reduce vehicle emissions. -The idea of using an 'impulse' of electricity that supposedly provides more energy is ridiculous. Where is the extra energy for this special spark plug coming from? How is this 'impulse' different from a spark, anyway? A spark plug is a resistance gap, exactly like the 'pulse plug'. Regardless, it doesn't matter because there aren't any gains to be had from burning gasoline in a different way than car manufacturers already design.
If you're not convinced, go ahead and buy them. Go put them on a brand new vehicle and see what happens. The gas mileage is not going to go up unless you already have worn out spark plugs that cannot perform the way they were designed.
What makes a Pulse Plug?

Terminal: This is the primary connection point to the rest of the ignition system. It is shaped so the wire usually just snaps onto the top of the plug.
Insulator: Made from an aluminum oxide ceramic that is able to withstand very high temperatures and protect against the high-voltages that the ignition system requires from ‘leaking out’.
Resistor: This is what keeps EMI and RFI from getting into the advanced computer systems of today’s automobiles.
Pulse Circuit: This is what separates a pulse plug from a normal plug. Here, the energy is stored to be released into the gap once breakdown voltage is achieved by the ignition system. A typical plug will have only the resistor then a conductor that continues to the center electrode.
Plated Shell: This provides the hex to torque down the plug, the threads to hold the plug in the engine, the sealing surface to keep combustion gasses in the engine, the mounting point for the ground strap and the connection to ground for the plug.
Gas Seal: This part of the plug keeps the combustion gasses from just pressing out the center electrode on the plug and causing a leak. Center Electrode: The center electrodes on plugs are made from many different materials from copper to inconel to iridium. This is the first half of the plug that actually creates the gap for the spark.
Ground Strap: The ground strap is the second part of the gap and comes in a multitude of shapes and materials. One example is the Bosch platinum series that come with your choice of one, two or 4 ground straps.
How you get a spark
When the ignition event in an engine is needed what happens in the ignition system depends on the type of ignition system.
In an inductive ignition system the primary side of the coil is always energized at 12v until it’s disconnected; when the primary is disconnected the magnetic field on the primary collapses and induces a 30,000v charge on the secondary coil which has the spark plug as its load.
In a CDI(Capacitive Discharge Ignition) system the signal is sent to the CDI circuit which sends a short, high-voltage pulse to the CDI ignition coil. The CDI ignition coil is basically just a transformer that takes the 250v input voltage and steps it up to around 40,000v very rapidly. In either case, what you get is a high voltage charge that is used to create the spark that ignites whatever fuel the engine happens to be burning, from ethanol to gasoline.
The breakdown voltage required to cross the gap in the engine depends on a multitude of factors such as air temperature, air pressure and fuel saturation. Assuming normal atmosphere the breakdown voltage required for a typical .044" plug gap and compression pressure of 160psi is around 25kv. That is a typical engine usually at full throttle, additionally, when the engine is at part throttle that voltage demand decreases significantly.
When the plug gap reaches its breakdown voltage requirements a plasma stream is formed from the center electrode to the ground strap on the plug. This plasma stream has zero resistance and drains the available power from the pulse circuit in about 2 microseconds. After this the normal resident stage of the spark continues until the coils have discharged and the process starts again.
The breakdown of the gap in a plug will cause electromagnetic and radio frequency interference. Proof of this is in old spark-gap Morse code transmitters that relied on this interference for transmission. This interference would cause havoc with new electronic ignition and fuel injection computers, not to mention the radio frequency interference causing problems in radio reception. These resistors are in the plugs and also resistance is put into the plug wires leading to the plug. In a pulse plug the insulation from interference is still there but it’s before the pulse circuit and therefore the stored energy has an open pathway to freely discharge across the gap.
What does this mean in the engine
Pulse plugs take advantage of the charge / discharge cycle by storing energy on the voltage rise into its capacitor and releasing it very quickly when the breakdown of the gap happens. Instead of a typical spark that has 25kv and .05amps, the pulse plug can, for around 2 microseconds, put 50 amps across the gap. Since the gaps are usually the same as or less than your normal spark plug, and timing is unaffected since the spark voltage and length do not change.
