This means that drivers no longer have tired of stepping on the clutch to shift gears. On cars with manual transmission, to shift gears, the clutch must be pressed.

Another fact, of all the control systems should be operated driver’s car, the clutch is the most energy-consuming. In addition, the level of operation is also very high, especially when traffic jams or solid creep!

Easy out
Nevertheless, it turns out there are still many among us who still assume negative effect on the automatic transmission. It is also recognized by auto manufacturers. For example, if the strike, cars with automatic transmission can not be encouraged. If is often used in mountainous areas, brake quickly exhausted.

All the assumptions of the past. Now, more and more automatic transmission, the manufacturer provides the mechanics who have the ability to fix it faster if there is a problem. In fact, now there is also a general workshops that could deplete the entire automatic transmission fluid (ATF) in the transmission and then filled with a lubricant that really new and clean.

In the car now, especially the use of injection systems, when the battery is weak, then the machine will not start. Because the engine computer to get energy from the battery. Therefore, the position of manual and automatic transmissions the same!

Then, on the assumption that the automatic braking when the car drove lavishly in areas with many derivatives, ascertained, that the condition occurred because the driver was too relaxed, allowing the transmission to position “D” course. In fact, D is the highest gear.

Keep working
To reduce the workload of the brakes, the driver must use engine brake effect by using a lower gear. In this case, it could be “two” or if more steep and slippery, should be “L”. Same with low teeth, 3 or 2 on the manual transmission. As for acceleration, the driver should kick or step on the gas pedal down fast!

So, driving with automatic transmission that does not mean the hand does not work at all. At a certain field conditions, 3, 2, and L should be used. Hand still be active. Only the left foot is completely relaxed. No need to stampede the clutch at all. For example when the streets are declining or accelerated during the ascent!

In fact, the bad conditions, by releasing the brake pedal and transmission at the position “D”, the car can crawl without having to hit the brakes.

If you already taste the delicious automatic transmission, especially for those who drive themselves, often through a traffic jam, and have high mobility, they certainly will not want to go back to manual if you do not have to. In fact, they are willing to spend additional costs, both for the transmission of more expensive fuel consumption plus a little more than manual

In driving, there is the term “understeer” and “oversteer”. Maybe you have or have often heard these two words. Just like what the symptoms of a vehicle, perhaps you have not experienced it. Or if ever, perhaps because you do not feel it does not know which one over, which is under.

Well, to understand it, can see the explanation below. Also, how to cope when experiencing.

Understeer
Symptoms tend to car straight, although the steering has been deflected. Commonly known as skid traction because the front is missing. If this was a panic-drivers-especially large potential for harm because the car out of the road.

How to cope :

1. Immediately slowed until traction vehicle back.

2. Do not add spin the wheel, or brakes.

3. Cut down on the accelerator gradually.

4. Reduce the steering wheel rotation.

Oversteer
The opposite of understeer, the rear tires lose grip. Consequently, the stern of the car to shift or twist.

The cause, most commonly we do braking when turning. At that time, the weight moves forward so that makes the rear tires less grip on power. Another factor for turning the steering wheel abruptly.

The danger, the car can be out of control and collided with something from the side. Meanwhile, the sides are not protected as well as front or rear.

How to cope :

1. Do not brake.

2. Do not move the position of the hands on the steering wheel.

3. Make a counter-steering or “reply to” steering wheel with alacrity, but not excessive.

4. Cut down on the accelerator (for rear wheel drive car).

5. Add just enough pressure on the gas pedal (for the front wheels moving car).

6. Move your eyes to the point of going to the intended

7. Be prepared to return the wheel to its original position

For motorists who drive a car with a Multi Information Display (MID) device can easily monitor the use of fuel. Then, how about the MID figures show that wasteful fuel usage? Least wasteful fuel consumption also depends on driving style, technical factors other than mechanical course.

Here are some tips and tricks that need to be done to reduce fuel budget:

1. Do not stomping.
   Pedal must be stable and gradual. If you step on the gas pedal abruptly, auto fuel that will be sucked into the combustion chamber is also growing. Meanwhile, at that time was still low engine rpm. Consequently not all that fuel into the engine room fire. Which is called a waste. Because no fuel coming out in the form of energy, but go wasted through exhaust.
2. Discover the engine RPM.
   One way to make an efficient fuel consumption is to change gear (transmission) the right, which is when the engine reaches maximum torque (maximum moment).Gearshift when cars were in need of torque (thrust force), should be conducted with respect to information about the maximum moment (maximum torque) of each car (usually in units of kgm / rpm). Meanwhile, if the vehicle is moving (where the thrust is not needed), the most efficient when driving with the RPM between 2500 until 3500 and with the highest gear.

   For example, technical data on the manual written book Maximum torque: 200Nm/3750rpm. This means that the highest moment of 200Nm occurs at the time of rotating machines as much as 3750 per minute.

   In this example, means that we should make the shift gear when the figure shows the range of 3750 rpm. Figures can be viewed at RPM tachometer located on the dashboard of a car.

   Figures RPM on tachometer very important note. To streamline fuel consumption, while speeding down the road. Keep the engine speed at the maximum torque range. Because, that’s when fuel supply is in accordance with the output from the machine.

   One habit that is often overlooked driver is: do not immediately adjust the gears after lowering speed (deceleration). After running hard and then suddenly put the brakes suddenly, you should also pass the shift gear to a lower position.

3. Measure the HC and CO.
   Whether or not extravagant consumption of fuel is also determined by engine components. Machine components that have a lot of wear / damage can cause incomplete combustion processes.To detect it, check the exhaust emissions. If the examination results show the value of HC (hydrocarbon) and CO (carbon monoxide) is too high, this is a sign of combustion in combustion chamber is not perfect (lots of wasted fuel).
4. Expenses and Activator.
   Another factor that determines the fuel consumption is a load and drive (drive vehicles). Increasingly heavy burden to be transported, their consumption will also increase. The definition of driving include: couplings, bearings (wheel), coupling (propeller shaft), axles, and wheels.

   When these components worn or damaged, would cause loss of power generated by the engine to push the car running. Meanwhile, fuel consumption remains large. Related to the wheels, use of large tires and wheels, including the factors that affect fuel consumption.

Here, other tips are also noteworthy:

1. Habits out of the office lunch / evening, preferably reduced. Bring lunch / delivery seemed better.
2. If traveling, take the family / colleagues that one purpose / intention to go together in one car. For the same matters do not necessarily have to run two or three vehicles while with one unit will suffice.
3. Switch to public transport such as busways, railway, or metrominis.
4. When a traffic jam, while out of town, you should stop first. Changing other activities such as rest, eat, go to the bathroom, or fill the fuel to decompose congestion.
5. Drive gently. Reduce the frequency of braking. When facing a red light does not need to step on the gas, let the car slide because they must be stopped. Reduce the frequency stepping on the gas and brakes. This is the step energy disposal in vain.
6. When sliding or decreased, gear should not be positioned at neutral. Engine brake effect proved more economical fuel than stationary.
7. Turn on the AC as needed.
8. Ask workshop setting appropriate timing according to the type of fuel used. Ignition point too forward or backward resulting wasteful of fuel.
9. Clean the air filters (can be done by yourself) per 2500 km, or depending on conditions.
10. Do not heat the car for too long, maximum 2 minutes. Warming-up machine for 30 minutes, synonymous with traffic for 30 minutes as well.
11. Find the route / alternative road is not jammed, out a little with the current path is more save.

“Paradigm has changed. The smaller the engine capacity, “said Fred Becker, Director of Sales Engineering Concepts NREC, a company turbocharger producers from the United States, at SAE World Congress in Detroit last week.

However, the performance is not sacrificed. “In fact, the more intense, more efficient, and exhaust gas emissions are also so low. The car was driven by steady on a variety of conditions, “he added.

Actually, the trend has been underway since last few years. For example Volkswagen, which developed TSI engine. Although the 1.4-liter engine capacity, ability to match the 2.0-liter engine. VW engines have been used on products sold in Indonesia, the Touran MPV.

Gasoline engine-now-especially great because the more applications are combined with direct injection technology petrol or gasoline direct injection (GDI or DI) and the turbocharger. Especially for the turbo, this system does not only work on medium and high speed, but starting from the start. Turbochargers also no longer owned a large capacity machine, but also a small engine, below 1.5 liters.

Noise
In addition to boosting performance machines that are more efficient, development by turbocharger manufacturers is to reduce the noise caused by this device. For that, the engineer who specializes in automotive turbochargers special-application re-analyzing and designing turbo subcomponents, such as shape, angle, and the size of the fan leaf (blade-blade). Result, the ability of the turbocharger is now more intense.

In addition, because many companies are interested in automotive component suppliers producing turbochargers, new ideas emerged. For example, designing a turbocharger with a miniature model of water cleanup pumps in nuclear reactors.

There also are making impellers (blade-blade) as a hydroelectric turbine (power plant) is safe through the fish. Some are made to replace the axial fan tail rotor helicopter model. In fact, the NREC has managed to create a highly efficient turbocharger, capable of reducing NOx, and worked in the radial.

Recovering energy
“No less attractive because of design and engineering knowledge continue to grow. Turbochargers are designed specifically for current generation gasoline and diesel engines, “said Becker. Therefore, the upcoming turbocharger designed for smaller engine capacity and number of cylinders a little, for example, four, three, or even two cylinders. “In fact, had anyone have an idea to unite the turbo unit with EGR (exhaust gas recirculation),” Becker beber.

During this time, the development of automotive turbochargers on slow assessed. The reason is, the added value obtained from the turbocharger a bit.

“In order to obtain greater value added, research is now focused on the turbo impeller aerodynamics,” he said. He added, later not only to boost turbocharger (boost) power of the engine, but also to restore or recover energy.

Trends in the use of automatic transmission cars in Indonesia rose. Operation even easier than the manual, without the clutch. Nevertheless, it does not mean man can not make mistakes. And, the behavior of one can make the lifetime becomes shorter.

Transmission damage due to improper operation of only 10 percent, 85 percent of the largest oil change just due to negligence, while 5 percent due to the age of consumption.

There are minor omissions, negligence, although not fatal, to be the beginning of transmission damage. Like what is negligence?

• Do not move the lever to N. We stopped a long time in a traffic jam or a red light, sometimes the driver continues transmission rod in position D. This condition makes the transmission of extra work due to work as a limited supply of fresh air. If the stop of more than 60 seconds, immediately move the transmission to N so that lubricants do not increase dramatically.
• Step on the gas into the D. We sign up at the lights, so the sign is green, drivers often move the stick directly to D and direct the gas pedal. In fact, the transmission takes time to engage with the process fluid pressure to move toward the torque converter. If this habit is often done selenoid valve inside the transmission can be easily damaged.
• Frequently perform engine brake. To obtain the effect of engine brake, may be used in low gear. However, the displacement was made during the 3000 rpm engine speed. Because, if on top of that, there could be hard to reduce friction and wear life of the clutch friction within trasmisi.
• Move position from D to R. Move the gear lever from D to R (to parking) needs to speed his hand. However, if done roughly, the conventional transmission could result in damage to the planetary gear and one way clutch. While outside of the transmission components that are affected like the dc coupling cross joint, engine mounting and the axle (front wheel drive).
• Prevent the transmission in first gear. Needs engine brake on the street or down a steep incline on the road acceleration performance, one would need a tooth. But, this condition should only be done as necessary and unavoidable when dealing with normal road conditions (flat). Therefore, the burden increasingly heavy clutch. Moreover, if continued into high gear on a conventional automatic transmissions still use valves. Can make performance pedal parts behind the piston can be problematic due to excessive pressure.
