AMT – automatic manual transmission – Clutch less

AMT – automatic manual transmission – Clutch less. Guys in the previous article their was a lot of discussion over the automatic manual transmission (AMT).So what I decided is to give a article regarding this technology,this article gives a knowledge about this technology in easy words with a deep meaning. You know what guys, basically this technology evolved as a result of reduction of cost as compared to the automatic transmission and to get the same fuel efficiency as that in the manually geared automobiles.

AMT – automatic manual transmission – Clutch less

Now moving on to what basically it is,so in short we can say that AMT is a electro-hydraulic mechanism basically designed for automating manual transmission.

AMT - automatic manual transmission - Clutch less

AMT – automatic manual transmission – Clutch less

AMT is based basically on a electronic control unit and a hydraulic system that govern the clutch use and the gear shifting. It basically permits the driver to change the gear without the use of clutch.

The basic 3 functions which are performed are-

  • · Opening and closing of clutch.
  • · Operation of gears.
  • · Controlling the choice of transmission(mode of changing gears).

And this all is governed by the hydraulic actuators, controlled by the electro hydraulic valves.

The basic outcome of the AMT technology is that it it reduces the emission of CO2. Mechatronic is basically the latest generation of this technology. AMT (automatic manual transmission) gives a especial feature to combine the Electronic controls with the hydraulic systems in the single unit.

AMT – automatic manual transmission is also known as the semi automatic transmission.

The basic advantage is that it gives more direct contact of engine and the wheels thus it is used where the high performance is needed.

OPERATION - AMT – automatic manual transmission – Clutch less

Basically the gear stick in such systems is different then the traditional ones. But the gear lever is the same. In few cars using this the gear stick can only move forward or backward to shift the gears.Their is no use of the H pattern. In Bugatti veyron such system is used.

While the formula 1(F1) or the Ferrari uses the paddle shifters in which we need to press right and left paddles of the staring to change from high to low gears or visa versa.

Sensors are there which predict the direction of shift.

The main emphasis of the systemliesin the fact that the electrical equipment can react much faster then human also without the intervention thus making the performance a much better one.

Hope u like the article the next time it will be a much more interesting topic so stay tuned.Suggestions are always greeted.

Maruti introducing a clutchless car

Its been a while that I was not able to update with my article. But the reason was that I was in search of a new and a fresh topic. And what I found was amazing car THAT WILL BE introduced by MARUTI SUZUKI In the DELHI AUTO EXPO.

Maruti introducing a clutchless car

Maruti Suzuki is the leading car manufacturer of Indian automobile world, and to keep up their triumph over others they are coming out with one more technology of AMT(Automatic Manual Transmission). Though the automatic transmission is not new in the automobile world but maruti Suzuki in itself to introduce automatic transmission in the year 1987.
The AMT is used in F1 cars but on the small cars this technology is used the first time…!
Maruti has brought in a new technology to use the manual gears like automatic transmission without having the involvement of clutch. Now the technology used here is known as the automatic manual transmission. AUTOMATIC MANUAL TRANSMISSION(AMT)- the AMT technology gives 5% more mileage then the automatized transmission system.

Introduced in its global hatchback and making its world debut in delhi expo it is learnt that it is new offering celerio. Though many companies have tried to make such use of technology(i.e AMT) but have failed to do so due to some or the other reasons. Now the biggest advantage of this technology is that,it is giving the same fuel efficiency,as well as the cost is same. Though there is a bit of hassle regarding the cost,but certainly it will be costlier then the manually geared ones and cheaper then the fully automatic ones. “It gives the comfort of automatic transmission and the fuel efficiency of the manually transmitted cars”.this was the saying of a high authority of maruti. He also added that that customers can change gear like automatic transmitted but the cost will be same as that of manually transmitted. It is expected to have a K-series engine also used in wagonR A-star.with 1 ltr capacity.with fuel efficiency of 20km/l.

International Atomic Energy Agency

International Atomic Energy Agency. The IAEA serves as an intergovernmental forum for scientific and technical cooperation in peaceful use of nuclear technology and nuclear power worldwide. IAEA was established in 1957 and has its headquarters in Vienna, Austria. The IAEA has two “Regional Safeguards Offices” which are located in Toronto (Canada) and in Tokyo (Japan) and it also has two “liaison offices” which are located in New York City (USA) and in Geneva (Switzerland). In addition, the IAEA has three laboratories located in Vienna and Seibersdorf, Austria, and in Monaco.

International Atomic Energy Agency

History of International Atomic Energy Agency:

1) In 1953, the President of the United States, Dwight D. Eisenhower, proposed the creation of an international body for regulating and promoting the peaceful use of atomic power.
2) During 1956, an IAEA Statute Conference was held to draft the founding documents for the IAEA, and the IAEA Statute was completed at a conference in 1957.
3)From IAEA’s commencement in 1957, it has been operated and controlled by many Director- Generals viz.
o Sterling Cole (1957-1961)
o Sigvard Eklund (1961-1981)
o Hans Blix (1981-1997)
o Mohamed ElBarade (1997-2009)
Yukiya Amano(2009 to Present)
4)Both the IAEA and its then Director General, ElBaradei, were awarded the Nobel Peace Prize in 2005. In ElBaradei’s acceptance speech in Oslo, he stated that only 1% of the money spent on developing new weapons would be enough to feed the entire world.

Mission of International Atomic Energy Agency:

The IAEA has following missions :-
1)Peaceful Uses :- Promoting the peaceful uses of nuclear energy by its member states.
2)Safeguards :- Implementing safeguards to verify that nuclear energy is not used for military purposes.
3)Nuclear Safety :- Promoting high standards for nuclear safety.

Structure of International Atomic Energy Agency:

International Atomic Energy Agency
International Atomic Energy Agency

The IAEA’s objective is guided by the needs of its member states. The IAEA is an autonomous organization which does much of its work with the Security Council and it also reports to UN General Assembly.
It has three main bodies :-
1)Policy Formulators: This body is responsible for making policies and comprises of

International Atomic Energy Agency
International Atomic Energy Agency

a)Board of Governors :

It consists of 22 member states elected by the General Assembly and at least 10 member states nominated by the outgoing board. The outgoing board designates the 10 member states who are most advanced in atomic energy technology. The 22 elected members must also represent a stipulated geographic diversity.
The Board gives advice and recommendation to the General Assembly on IAEA’s activities and budget and also appoints Director-General with the approval of General Assembly but the chairman for the board is elected by the board itself.

Fast Multiplication Trick – Short Cut method

Fast Multiplication Trick – Short Cut method. Hello friends, Today, we are going to discuss about some multiplication tricks Short cut method. Look, everybody knows How to multiply two-digit numerals but in competitive exams what matters the most is time. So if you are doing it in less time then only you will qualify or get good marks in the exams.

Fast Multiplication Trick - Short Cut method

Fast Multiplication Trick – Short Cut method

So to elaborate my point further let’s take some examples:
1)34*12
2)25*14
Now, just observe the above examples and instead of multiplying these numeral conventionally, Take them as if :

Example and steps for Fast Multiplication Trick – Short Cut method

e.g. 1) You are recalling the table of 34 up to 12.

For that, just follow these steps:
a) Multiply the number (other than the number which is close to 10)by 10 i.e. 34*10=340
b) Now recall the table of 34 two more times and for that just multiply 34 by 2 i.e. 34*2=68
c) And finally add the result obtained in both the above steps 340+68=408 and you’re done.

Similarly for the second
e.g. a) 25*10=250
b) 25*4=100
c) On adding 250 and 100 you’ll get 350 as simple as that.

So you can use such types of tricks while multiplying any 2-digit numeral within the range
of 11-14 with any other 2-digit numeral. I hope this article will help you a lot. And we will discuss many more such type of tricks in my subsequent articles. For any suggestions and expressing your views, do comment below.

Fast Multiplication Trick – Short Cut method – Vedic Maths

Fast Multiplication Trick – Short Cut method – Vedic Maths. Hi guys, in my previous article of Multiplication trick we have discussed about multiplication of 2-digit numerals out of which one numeral can be any 2-digit numeral & other one should be in the range of 11-14. Now we will discuss about 2-digit numerals in which both the numerals are close to 100(& also less than 100).

Example and steps for Fast Multiplication Trick – Short Cut method – Vedic Maths

To understand that, let us take an example :.
1) 96*90
Now subtract 100 from both the numerals,so after doing that we’ll get -4 and -10.
Then follow the steps as depicted in the figure.

Two Stroke engine – Petrol and diesel

Two Stroke engine – Petrol and diesel. Guys, basically a stroke means the linear distance the piston moves between the top dead center (T.D.C)and the bottom dead center(B.D.C).so as the name suggest “2-stroke” means that the piston moves two times In between T.B.C and B.D.C. In other words we can say that a engine in which 2 strokes are carried out by the piston can be termed as a two stroke engine.

  • The basic concept of a two stroke engine is that all the essential operations are carried out in one revolution of crank shaft or two strokes of the piston.

Classification of two stroke engine

  • 2 stroke petrol engine
  • 2 stroke diesel engine

Basic components of a two stroke petrol engine

Difference between Two Stroke engine – Petrol and diesel

 


Petrol engine

Diesel engine
In a petrol engine we use spark plug for spark ignition While in the diesel engine we use fuel injector and thus accomplish a task of compression ignition
Petrol engine uses a carburetor the main
function of which is to properly mix the charge (air + fuel).
While there is no such facility in a diesel
engine
In petrol engine charge in the form of air +fuel In diesel engine the charge intake is only
in form of air
A petrol engine works on Otto cycle A diesel  engine works on diesel cycle
Operates on constant volume process Operates on constant pressure process
Uses gasoline as a fuel or petrol alternatively Uses diesel as fuel
Better efficiency for same compression
ratio
Low efficiency
Cheaper engine. Costlier engine
Less maintenance More maintenance
Easy to start due to lower
compression ratio
Difficult to start

 

Here is the Diagram showing Otto Cycle of Petrol Engine and Diesel Cycle of Diesel Engine:

General Working Of Two Stroke engine – Petrol and diesel

Two Stroke engine – Petrol and diesel
  • OPERATION-

In a two stroke engine,the inlet ,transfer and exhaust ports are covered and uncovered. By the movement of piston so according to the opening and closing of exhaust , inlet and transfer port following process es take place in a two stroke engine.

  • CHARGE TRANSFER AND SCAVENGING-

When the piston is nearer to the B.D.C,the transfer and exhaust port open up.the charge is slightly compressed due to which it enters the transport port and due to which it drives out the exhaust gases in the cylinder through the exhaust port.

IT CAN BE SEEN FROM THE DIAGRAM THAT  THE PISTON TOP IS MADE DEFLECTED IT IS BASICALLY DONE TO DEFLECT THE INCOMING CHARGE UPWARDS AND THUS SWEEPING OUT THE BURNT GASES.THIS PROCESS IS KNOWN AS “SCAVENGING”.

  • COMPRESSION AND SUCTION-

As the piston now moves upwards  the exhaust port and the transfer port are been closed and thus the charge is been trapped and the charge inside the cylinder is compressed.at the same time due to crank movement the suction poet opens and  due to the partial vacuum created due to compression ,the fresh charge is forced inside.

  • COMBUSTION-

As the piston reaches T.D.C a height intensity  spark  ignites the spark and thus start the combustion.due to this height pressure is generated inside the cylinder and it is forced downwards.at about 80% downward stroke the exhaust gases move out through the exhaust port.and now  the gases again enter the cylinder in form of new charge due to pressure difference this process is called “charging”.

These were the basic process that takes place in both diesel and the petrol engines,but in the diesel engine we use  fuel injector instead of spark plug.

SPARK PLUG – two Stroke engine – Petrol and diesel
FUEL INJECTOR – two Stroke engine – Petrol and diesel

Port timing diagram for  petrol engine

After studying the working we need to look at the port timing,which refers to the relative opening and closing of the ports with respective to the crank rotation.

  • COMPARING TWO BRANDS - BRAND -A v/s BRAND-B

“What makes a racing engine so powerful and fast? Well it is the small details that make the difference. Probably, huge amounts of money invested in R&D; it’s not just on the engine design, but also on the manufacturing of the engine. Many racing engine manufacturers use special equipment to make their parts, like laser cutters and special high precision balancing equipment that your ordinary tool-and-die shop simply doesn’t have access to. The process control necessary to make a piston and sleeve assembly that will seal properly at high temperatures and last while being used in an engine capable of turning 30,000 RPM, is not easy. One single out of spec part could cause the engine to fail prematurely. Simple numbers like engine displacement and the color of the heat sink head are not going to tell you if the engine is any good or not. Even the manufacturer’s suggested HP has to be taken with a grain of salt. Engine “A” can crank out 1HP… under what conditions? What temperatures? How long? At what RPM? These are all blurry claims. It’s best to ask around your local track and choose a manufacturer with a history of good, reliable, and easy to tune engine designs. It’s always better to ask around than to waste your hard earned money on the flavor of the month engine manufacturer. Hey, with basic machining tools and a CAD model, anyone can make an engine. It takes years of experience and machine know-how to build a great engine! Make no mistake, some of the sport engines from the manufacturer “B” will burn the barn doors from the turbo model of brand “A”.”

Tips for better running of two stroke engines-

For smooth running of the engine we can use engines with less peak horse power.another method would be to adopt a suitable transmission system according to the needs.another implementation can be  by doing proper tuning  of pipe designs in order to help the 2 stroke engine.

Where are two-cycle engines used?

Two-cycle engines are inexpensive to build and operate when compared to four-cycle engines. They are lighter in weight and they can also produce a higher power-to-weight ratio. For these reasons, two-cycle engines are very useful in applications such as chainsaws, Weed-eaters, outboards, lawnmowers and motorcycles, to name just a few. Two-cycle engines are also easier to start in cold temperatures. Part of this may be due to their design and the lack of an oil sump. This is a reason why these engines are also commonly used in snowmobiles and snow blowers.

Some advantages and disadvantages of two-cycle engines

Because two-cycle engines can effectively double the number of power strokes per unit time when compared to four-cycle engines, power output is increased. However, it does not increase by a factor of two. The outputs of two-cycle engines range from only 20 to 60 percent above those of equivalent-size four-cycle units. This lower than expected increase is a result of the poorer than ideal charging efficiency, or in other words, incomplete filling of the cylinder volume with fresh fuel and air. There is also a major disadvantage in this power transfer scenario. The higher frequency of combustion events in the two-cycle engine results in higher average heat transfer rates from the hot burned gases to the motor’s combustion chamber walls. Higher temperatures and higher thermal stresses in the cylinder head (especially on the piston crown) result. Traditional two-cycle engines are also not highly efficient because a scavenging effect.

How are two-cycle engines lubricated?

Two-cycle motors are considered total-loss type lubricating systems. Because the crankcase is part of the intake process, it cannot act as an oil sump as is found on four-cycle engines. Lubricating traditional two-cycle engines is done by mixing the oil with the fuel. The oil is burned upon combustion of the air/fuel mixture. Direct Injection engines are different because the fuel is directly injected into the combustion chamber while the oil is injected directly into the crankcase. This process is efficient because the fuel is injected after the exhaust port closes, and therefore more complete combustion of fuel occurs and more power is developed. Direct injection engines have a higher power density than traditional two-cycle engines. Because the oil is directly injected into the crankcase, less oil is necessary and lower oil consumption results (80:1 range). Direct Injection motors have higher combustion temperatures, often up to 120F. They also require more lubricity than traditional two-cycle motors.

String Trimmer – Application And Example Of two-Stroke Engine

It is known as a weed eater by other name. it is basically a tool used for cutting tools. String trimmers powered by an internal combustion engine have the engine on the opposite end of the shaft from the cutting head .the gasoline engine is of about 21cc and is two stroke most of time. Most trimmers use two stroke engines and require gasoline mixed with oil. But the disadvantage is that it pollutes heavily.

  • internal combustion engine (ICE) powered bicycles-

it is a type of bicycling which uses  a engine and transmission system for the purpose of ease in paddling. Small two-stroke, bolt-on gasoline bike motors and adapter kits for bicycles had a brief surge in popularity in the late 1960s and early 1970s in the U.S. and Canada. These engine kits were designed or marketed by both small and large companies, including Bike Bug, Taps Spitz.
