Changing BMW Become Best Electric Exhaust

According to the experts and engineers, despite the current machines is very efficient in turning fuel energy into heat, only a third of which can be used to propel the car. As many as two-thirds of the waste in the form of heat through the exhaust and radiator. Well, now wasted heat energy that want to use. Various methods were done! One of them is an ambitious project of BMW engineers in Germany.

Hot start
The first idea is to start the car manufacturers experts based in Munich is no longer distart engine is cold. Thus, the move could reduce konsusmi fuel and emissions. For that, the engine was covered, like a thermos so that the temperature is maintained.

All the machines covered or fitted with heat insulation. Thus, the engine will stay hot when turned on again. Materials for insulation is not expensive, which is similar to that used for the floor.

After contact OFF or turned off the engine, the temperature remains 40 degrees Celsius after 12 hours. Every degrees Celsius above the ambient temperature around the engine will mengirit fuel consumption to 0.2 percent.

"Thermoelectric"
The second approach to change exhaust heat into electricity. The experts claim, this could mengirit fuel consumption by 2 percent. To that end, BMW uses the principle of thermoelectric generators have already been shown last year.

Further development is to use an integrated component in the cooling exhaust gas recirculation (egr). This method can produce 250 watts of electricity when the car was driven at normal conditions. According to BMW, that much energy equal to half the electrical energy required 5-Series sedans today equipped with various electrical and electronic equipment.

Thus, they use the element thermoelectric semi-conductors to produce electricity. The greater the temperature difference, the greater the high voltage generated.

Exhaust temperature typically ranges between 300 and 900 degrees Celsius. This section is used as the hot side of the generator, while the cold is the engine coolant.

Described, 3 to 8 percent of all fuel consumed by cars of today are used to operate equipment that requires electrical energy. Therefore, this method is very pontensial assessed in mengirit fuel.

The third version uses the waste heat from the radiator to knapot or channeled to the interior of the heater. However, this method can only be used in cold climates or in winter.

Traffic Management
Heat engines can also be used to reduce friction. That is, the machine is set to work at the appropriate working temperature. For example, transmission. This tool is used for heat exchangers (heat exchanger) that could heat up quickly on the transmission normal working temperature.

In fact, according to BMW, they also have the possibility of using aerodynamic system that can be set to prevent the heat energy wasted. Other efforts are now in use-is the regenerative braking system (like KERS).

In fact, traffic management with the help of satellites, according to BMW, can help reduce fuel consumption while reducing emissions. By controlling the satellite, acceleration and braking can be done smoothly.

Apparently, a navigation system not only to avoid bottlenecks and waste a lot of energy spent in vain, but also to reduce pollution in large cities.

Automatic Parking Fast and Secure with Sensor "Ultrasound"

One of the problems frustrating enough drivers are parking in the cramped space. More difficult again, the available parking space was in a position perpendicular to the car. Add another hassle, parking is expected to help deliver on cue, shouts, and the code does not exist! Can stress!

In fact, since 2008, car manufacturers have started to equip their products with a technology called parking assist or parking assistant. But now, the vehicle enhanced by using ultrasound sensors to monitor objects that are not visible or blind spots. Reported by Bosch of Germany.

Preventing bump
With ultrasound sensor, parking assistant working ability even worse. Sensors that provide comfort to the driver and the parking process go faster.

"Its function is more fun because it helps the driver parked the car with ease in parking spaces is very limited, especially with the right angle. In addition, there are also additional warning system to prevent side collisions. This parking assistant helps not only parking, but also out of the parking lot, "says Dr. Rainer Kallenbach, executive vice-president of Sales of the Bosch Automotive Electronics Division.

He added, Bosch focus creates "sensory organs" so that the driver is not stressed again when parking. In addition, this tool also helps smooth the traffic, especially the parking places. "With parking assistant, the process of parking and out of the parking lot so more quickly. This also prevents the possibility of blisters due to car body nudging objects or other cars, "said Kallenbach.

"Power steering" electricity
Currently, parking assistant semi-automatic only used in cars with electric power steering. The system only works with helping turn the steering wheel. The drivers still have to control and operate the gas pedal and brake.

Later, the system will be developed along Park Steering Information. In this way, the driver can get the maximum movement can be done when parking. In fact, the system will be used on cars that still use hydraulic power steering.

More sophisticated, parking assistant helps the driver out of the parking space. The technology is moving the steering wheel, while the driver stepped on the gas just to get out of the parking lot. The system will cancel the work if the driver holds the steering wheel and the brake pedal.

Ultrasound sensor is actually used in a parallel parking assistant. However, engineers are not satisfied with the features or the ability to work the parking assistant. They want, parking assistants can be applied to help drivers park in narrow spaces and difficult position.

"To park in a small space to turn broken, must use an ultrasound sensor with a range longer work. Should be able to measure the sensor depth of field with a longer range and precision, "Kallenbach beber.

Fully automatic
He also explained, with the use of ultrasound sensors, technology and workplace parking assistant has undergone a significant progress compared to previous versions. The problem, now a step toward technology that is also highly awaited car makers, the parking assistant that is fully automated. In this system, not just the steering wheel is driven by the assistant park, but also the gas and brake pedals. Meanwhile, the driver just watching the car's motion.

Other applications of ultrasound sensors is Side Distance Warning, which immediately produced by Bosch. This technology is used to the side of the car is not knocking the object or another car was parked.

Parking assistant technology originated from a simple parking pilot developed in 2006. He served to give information to the driver not to hit or bump another car or object in the vicinity. The first cars using this technology is the Citroen C4 Picasso used to measure the length of parking spaces.

Stay Fun with White Gown

We do tend to be critical when viewing another person's appearance. Dressed all in black, almost like a psychic, or to leave the wake. The dominant wear white, sort of like the paramedics or nurses. But why the assumption that vanished when we saw the appearance of celebrities in all-white outfit is this?

The secret may exist in the materials used, cutting, or accessories worn. Cameron Diaz looks at the reception attended the star on Hollywood Walk of Fame was (picture 1, left) to compliment many circles. Diaz wore a continuation of the material design lace Oscar de la Renta. As an accent, wearing a red belt wrap and pointy-toe heels with the same color.

In the middle, Megan Fox attended the premiere of Transformers 2 with a one-shoulder gown by Kaufman Franco, revealing a beautiful pair of arms. Black rope is loose dilingkarkannya hips. Kwiat diamond bracelet from her wrist was adorned.

Cameron Diaz still appear again with a white dress, this time owned by J Mendel designer, to attend the premiere of the movie My Sister's Keeper. Diaz appeared minimal with flowing hair on the shoulder, clutch, and nude color shoes.
