PULSE PLUG - AN INNOVATION IN SPARK PLUG ERA !!

Everyone is familiar about spark plugs. A brand called 'Pulstar' launched a new kind of spark plug called as pulse plug. Pulse plugs - a different innovation in spark plug technology and design acclaims to increase horsepower and fuel efficiency. The new pulse plug produces a stronger and wider spark when compared to the existing spark plugs. Generally the main work of the spark plugs is to ignite the charge (air and fuel) in gasoline engines. The more better and complete combustion of charge also drastically increases the horse power and efficiency. In this post lets see about the technology behind pulse plugs in comparison with existing the spark plugs.

Spark plugs work similar to a lightning bolt in clouds. To create a spark the power should have a very high voltage in order to travel across the electrode and create a good spark. 

Voltage at the spark plug can be anywhere from 40,000 to 100,000 volts. This high voltage is usually produced by an induction coil. This induction coil is similar to a step-up transformer to produce a high voltage discharge.

The high voltage from the induction coil is supplied to the spark plug by the spark plug cable and a spark is created between the electrodes of the spark plug.

In pulstar spark plug, a capacitor space is included in the plug which boosts the voltage when compared to an ordinary conventional spark plug. This high voltage discharge produces a wider and better spark. But it is not 100% guaranteed that it improves HP and fuel efficiency. Normally a new spark plug performs better compared to the old one, so it is tough to decide which is a better one.

NGK iridium spark plugs produce a consistent and steady spark area which improves performance. It lasts longer than ordinary spark plugs. The Pulstar pulse plugs are usually larger in size and pricy too, plus they don't have fit properly in many vehicles. Not available in our country.

The only advantage of using a pulse plug is that it can produce a spark with larger area. Hence the combustion becomes complete even the charge (air & fuel mixture) is lean or rich.

CARBURETOR VS FUEL INJECTION SYSTEM EXPLAINED !!

Why do more and more motorcycles now a day have fuel-injection systems rather than carburetor?  

So here is our discussion Carburetor Vs Fuel Injection – Brief Discussion.

The carburetor is one of the most essential mechanical part on a motorcycle and many small engine machines. All engines require a proper mixture of air and fuel for combustion; this vital device known as the carburetor controls the ratio of the fuel/air mixture entering the engine.

The fuel injected system is controlled by a computerized fuel delivery system, while the ECU takes information from various sensors and determines how much fuel the engine receives based on this data. Other sensors deal with RPM, engine temperature, throttle position, and the crankshaft position.

Carburetor Vs Fuel Injection System :

1. Fuel injector gives a slightly higher engine performance and slightly more efficiency when running at the best fuel-air ratio. Throttle response is also a bit better.
2. Crucially, most carburetor problems can be fixed easily at the side of the road with an assortment of basic tools. An electronic fuel injection system, though, if it goes wrong, will usually require a new part – and that’s going to cost you. Repair is far more difficult. Today’s modern fuel injection systems require a computer to diagnose the problem.

Advantages of Carburetors:

* Easy to operate and cheap to replace.
* Quick servicing.
* On the go tuning and setting possible
* Can be opened up individually without disturbing the engine.

Disadvantages of Carburetors:

* Diaphragm inside is delicate and can tear which will end up to have it replaced.
* The tuning process needs a big screw driver and has to be done physically.
* There is a certain amount of lag in the process of fuel delivery.
Old technology.
* The air-fuel mixture ratio is not constant.

Advantages of Fuel Injection:

* Fuel delivery is optimum and fuel atomizing allows for complete combustion.
* Increase in fuel efficiency and power output.
* Acceleration sensitivity increases.
* The air fuel mixture can be changed on the go using different fuel maps pre-loaded on the ECU for variable power outputs.

Disadvantages of Fuel Injection:

* Servicing of the FI unit is cumbersome.
* If there is an ECU failure, the bike will seize to work.
* It costs a lot and the service and maintenance is costly as well.
* Producing new Fuel maps needs loads of expertise.
* Procuring new fuel maps is a costly affair.

It is fairly obvious that most automobiles will be changing to fuel injection systems due to the lower emissions. However, unless the cost of these systems decreases significantly then there will still be a massive following that will stick to carburetors. When looking at pure horsepower, the fuel injection system only delivers about 10 extra horsepower at peak.

CHECK OUT WHY TYRES HAVE TREADS ON THEM !!

The tread of a tire or track refers to the rubber on its circumference that makes contact with the road or the ground. As tires are used, the tread is worn off, limiting its effectiveness in providing traction. A worn tire can often be retreaded.

The grooves in the tire are correctly called the tread pattern, or simply the pattern, but the word tread is often used casually to refer to the pattern of grooves molded into the rubber.

But why do tires have treads anyway? Why aren’t the tires on our vehicles bald with no treads like those on race cars?

The reason our tires look different from those outfitted to race cars, is because we drive for different reasons. Race car drivers require a smooth tread on their tires because it provides more grip during dry conditions. If dry conditions are not present, then they may switch to tires with treads.

Since the rest of us do not use our vehicles for racing, we frequently drive through adverse conditions, like rain, snow and mud. Since water accumulates on the road during these wet conditions, our tires need treads for better traction in these harsh conditions that we so often drive through.

The grooves that you see on your tires work to siphon water away from the tires when the roadway is wet. This can help to reduce the risk of hydroplaning when traveling at higher speeds on a wet road or highway. If the treads on the tire are not at the proper depth, it can become difficult for enough water to be carried out from beneath the tire, thus increasing the possibility that you could lose control in such conditions.

When a vehicle is traveling too fast, or the tire treads are not able to channel enough water out from beneath the tire, it can result in hydroplaning. This is where your vehicle loses contact with the road and skims across a thin layer of water instead, causing a loss of control.

That is why monitoring your tires tread depth is critical to vehicle performance and safety.
