HONDA COMBI BRAKE SYSTEM EXPLAINED !!!

The Honda Combi Brake system was introduced in India with the Honda Activa in 2009. However, this system has been in use since more than 30 years internationally. The Honda Combi Brake system is a first-in-industry technology.

What is the Honda Combi Brake System?

The most efficient way of braking is to apply the front and rear brakes simultaneously. But it is a practice, most two-wheeler riders have not mastered.Combi brake means that the brake will act on front and rear wheel together every time you apply the brakes. This means a lot of improved safety.

How does the Honda Combi Brake System Enhance Safety?

In two wheelers (scooters and bikes), there are two separate brake controls for front and rear wheels.Most of two-wheeler riders apply only rear wheel brake, or use only rear brake in most of the cases. However for most effective braking and stopping in small distance safely without loosing control, both front and rear brakes should be used together. Most people fear using front brakes too much because if you press them too hard, the scooter/bike may skid and the rider will fall badly.

Honda Combi Brake system applies the front-brakes in the correct amount whenever rear brakes are applied. This applies both brakes when you apply only rear one. This means that the scooter rider need not worry about using front brakes, they will be used in correct amount automatically when the rear brakes are used. See the image above, the highlighted green area shows how they have put an extra-cable to brake lever control of Honda-Activa 2009 to make combi-brakes work.

Advantages :-

Honda Combi Brake with Equaliser, ensures distribution of Force between the Front and Rear Wheel at the same time, giving perfect balance to the rider.

It ensures that rider with low expertise is also confident while braking.

Simultaneous application of Front and Rear Brake leads to the most effective braking.

TRACTION CONTROL SYSTEM EXPLAINED !!

Almost all super bikes and cars nowadays are using a traction control system to maintain an excellent stability and also to provide better safety.In general, a traction control system is identical to some of the commonly and widely used electronic systems in vehicles today like ABS brakes, fuel injection systems and damping control system which uses micro controllers. It can be also called in many other names like ESC (Electronic Stability Control) ESP (Electronic Stability Program) VSA (Vehicle Stability Assist) etc depending on the brand of a vehicle.

The super bikes and cars are usually equipped with high power engines which delivers instant power to the wheels to spin and move on. So when a situation like starting from halt to accelerate instantly and slowing down during cornering and accelerating again, there may a chance of wheel slip between the road surface and the vehicle. In bikes, the contact surface of tyres during cornering are not the same for both front and rear tyres. All these situations may lead to loss of stability & ultimately leading to an accident. 

You may occasionally experience a wheel spin when starting off or accelerating, particularly on a slippery or wet road surface. The Traction Control prevents wheel spin. While the Antilock Braking System ABS prevents the wheels from locking during braking by reducing the braking pressures, Traction Control ensures that the wheels do not spin when driving off or accelerating. To do this, the drive torque at each driven wheel is reduced respectively. Traction Control improves the traction of the vehicle and increases vehicle safety by avoiding unstable driving situations within the limits. 

This feature is available in all super bikes like Yamaha YZF-R1, Ducati Diavel, 1098, Kawasaki ZX14-R etc.

In some systems it also reduces the power output from the engine until the optimum traction between the tyre and road is obtained. In simple words its a reverse mechanism of ABS which senses wheel lock and in here the system senses for wheel spin.

DIFFERENCE BETWEEN SHAPER AND PLANER MACHINE EXPLAINED !!

In Shaper machine, tool is having reciprocating motion and w/p is clamped on table which is stationary. It is mostly suitable for light duty operation.In Shaping large cutting force is transferred to tool.

In Planer machine, tool is having stationary and w/p is clamped on table which is reciprocating motion. It is mostly suitable for Heavy duty operation.In planner large cutting force is transferred to table.

DIFFERENCE BETWEEN FORGING AND CASTING EXPLAINED !!

Casting and forging are both industrial processes of metal forming and shaping. Different process used in different conditions. The main difference between casting and forging is that the metal is compulsory to heat and convert 
into liquid stage in casting but in forging metal is converted into desire shape by applying pressure with or without applying heat. If the metal is preheated into forging it does not convert into liquid stage. But before differentiate this both terms; you have to know about what is casting and what is forging.

Forging vs Casting:

What is casting?

Casting is a process in which metal is heated until molten stage and pour this liquid metal into a mold or cavity where it is allow solidifying. This process converts the metal into desire shape. It is useful to make complex structure. Most of the industrial structures parts are like lathe machine bed, milling machine bed make big base of other machinery part, IC engine components etc. are made by this process.

Advantages of Casting

• This process can form very large structure which is impossible to form by other process.
• It can make any complex and unsymmetrical structure.
• The structure formed by this process has high compressive strength.
• It can attain wide range of properties.
• This process can attain high accuracy.

What is forging?

On the other hand forging is the process of converting metal into desire shape by applying pressure and with or without heat. When the metal is heated before applying pressure the process is called hot forging. In forging metal is heated before below critical temperature or below molten stage. Rolling, pressing, Wire drawing etc. is various types of forging. All sheets, small component, wire etc are formed by this process.

Advantages of Forging:

• It produces tougher product compare to other.
• The product made by forging has high impact or tensile strength.

CHECK OUT THE REASON WHY TRACTORS DO NOT HAVE SUSPENSION SYSTEM !!

First its required to get know what are things affected by a suspension system.

If a suspension is installed in a vehicle , then the vehicle will not have constant motion body. The body tend to oscillate in the direction of axis of the spring.

This oscillation can change ride height while operating . The condition may be while working or moving.Well tractors are supposed to maintain a constant depth in ploughing/digging. For this it requires the movement of the body to be restricted so that we do not disturb the main tractor functions.

If we have a suspended tractors which bounces too much over undulations in a field then we can't expect to have a constant ploughing depth which is a requirement in agriculture.

Suspensions also affects the off road stability.

As the speed of the tractor is less and the tyres big(which absorbs more shocks),the need of suspension is felt less. 

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.
