What is BlueEFFICIENCY?

BlueEFFICIENCY is not a single technology, but rather on the Mercedes-Benz collectively own series of environmental technology, the integrated environmental technology, including optimization of internal combustion engines, to improve combustion efficiency through hybrid technology to achieve zero emissions by battery and fuel cell vehicles travel and other aspects of the content, but also a description of the step-Benz zero emissions strategy. 85 to 2010 Mercedes-Benz models have been using this technology, including into the country C180K, E200, E260 and other models, these models will be in the fender labeled “BlueEFFICIENCY” sign.

1.BlueEFFICIENCY features

● improve the fuel efficiency of diesel locomotive type

there are a lot of new energy vehicles mass production but in terms of an integrated environment, the internal combustion engine over a long period of time will still occupy the mainstream forces and root out the potential of the internal combustion engine relative to the current environment more practical. The first step BlueEFFICIENCY strategy would include the existing internal combustion engine as a technology to improve meterPlanning, as one of the representatives of the CGI engine is mounted on top of the domestic C-class, E-class.

compared to conventional prior Benz supercharged engine, the maximum advantage turbocharged direct injection engine comprising a direct injection system. Regular gasoline engines typically petrol injected into the intake manifold, the gas and air mixture is formed into the cylinder for combustion. Since the injector of the cylinder a certain distance, the concentration of the mixed gas stream and susceptible to the switch valve, so that the theoretical air-fuel ratio is difficult to achieve. Direct injection engine can be a good solution to this problem by sophisticated computer controlled high pressure fuel is injected directly into the cylinder form, to achieve the mixing ratio of air and gasoline, precise control of injection timing, let the mixture burn more fully, to improve energy efficiency.

except for engine improvements, BlueEFFICIENCY integrated environmental technology further by reducing the weight, reducing the air resistance, friction reduction, energy management, and a series energy recovery means to reduce energy consumption, improve fuel efficiency, the province province, details of the measures is in place.

● practical use of hybrid technology

before the zero-emission era has not yet arrived, the hybrid is seen as one of the main forms of technology transition. The face of Lexus hybrid offensive, Mercedes-Benz BlueEFFICIENCY strategy, also launched its own hybrid products, and includes the weak mixing, strong mixing and other forms.

At present, the hybrid can buy products only BlueEFFICIENCY S400 HYBRID, S350 based on the development of a lithium-ion battery hybrid.

different from S350, S400 HYBRID power transmission in terms of improvements that include a modified gasoline engine of 3.5-liter V6, a subsidiary of the electromagnetic motor, a hybrid module is specially equipped 7G-Tronic seven-speed automatic transmission, and control the operation of the necessary electronic components, transformers, and high-voltage lithium-ion battery.

S400 HYBRID compact hybrid module, the disk type motor plays a dual role of starter and generator. Acceleration phase, the motor power assist intervention work, providing the maximum torque of 160Nm for additional 6-cylinder gasoline engine. andDuring braking, the electric motor acts as a generator role, can recover kinetic energy during braking loss.

S400 HYBRID hybrid module further comprises a ECO automatic start-stop system. When the vehicle is coasting to stop no more than 15 km / h speed (for example, before encountering traffic lights stop), automatic start-stop system will automatically turn off the engine until the vehicle started again. Once the driver releases the brake pedal or the accelerator pedal is depressed, the motor to restart the engine immediately.

Since mild hybrid, the motor power alone is not sufficient to drive the vehicle, the battery capacity is very limited, only a hybrid module plays the role of the auxiliary drive. Perhaps it is the compression function, the volume of the battery system has been well controlled, the additional weight of the overall system is only 75 kilograms, from the S400 HYBRID the price point of view, this hybrid system can also make people Gladly accepted.

abroad, has been released Benz hybrid further comprising a plug-in hybrid and diesel hybrid which hybrid version S500 is employed plug-in hybrid. In the driving battery, the hybrid vehicle can travel S500 in the case of complete electrical drive 30 km, the standard fuel consumption is only 3.2L / 100km, CO2 emissions of 74g / km. While eating less, but under the action of V6 gasoline direct injection engine, the hybrid module, S 500 did not shrink properties of the hybrid vehicle, which 0-100km / h acceleration time of just 5.5s!

The hybrid car is not simply a patent, diesel fuel having a high inherent properties with the help of hybrid technology, it is easier to obtain a good fuel efficiency.

As a representative of the Mercedes-Benz diesel hybrid models, E 300 BlueTEC HYBRID hybrid module equipped with 3.2L four-cylinder diesel engine, which only consume one hundred kilometers

● 1L but it can also be installed electric motors make it relies on pure electricity with zero emissions driving.

2.BlueEFFICIENCY the Glossary

BlueEFFICIENCY is not a single technology, but rather on their own Mercedes-Benz collectively series of environmental technology, the integrated environmental technology, including the optimization of the internal combustion engine, through hybrid technology to improve combustion efficiency to achieve zero-emission driving, and many other content via battery and fuel cell vehicles, Mercedes-Benz is also zero emissions strategy step by step description. 85 to 2010 Mercedes-Benz models have been using this technology, including into the country C180K, E200, E260 and other models, these models will be in the fender labeled “BlueEFFICIENCY” sign. The basic idea

● environmentally friendly technologies under the new guide

All along, SUV known as the “gasoline killer.” But now, the new engine technology has been prohibitive to make such a “gas guzzler” docile lot on fuel consumption. Mercedes-Benz released in New York in conjunction with BGL facelift lueEFFICIENCY technology is.

at the New York Auto Show facelifted GL released 350 equipped with the new Mercedes-Benz engine, the new engine is the use of the BlueEFFICIENCY technology, known as the GL350 BlueTEC (diesel version). The car uses a redesigned grille, bumpers, wheels and LED headlights.

GL350 BlueTEC which will replace the current version of the GL350 CDI BlueEFFICIENCY, Mercedes-Benz claims that, according to the car’s fuel economy 20-30% higher than the same displacement gasoline engines. The seven SUV’s battery life is impressive – to fill a tank of fuel can travel up to 600 miles (about 965 km). Not only is the GL350, fuel economy and enhance the rate of the GL-Class models for the other 5% of the entire GL-Class models are available to meet the Euro 5 emission standards.

In the engine, the Mercedes-Benz engine equipped with a series of new GL level. One of them is GL 350 CDI 4MATIC BlueEFFICIENCY engine, which is a can output 165 kilowatts (224 hp) power and torque of 510 Nm V6 engine. Allegedly, fuel consumption per 100 kilometers on average this engine is 9.3 liters. Top models for the GL 500 4MATIC models, this model is powered by a can output 285 kilowatts (388 hp) of power and 530 Nm of maximum torque 5.5-liter V8 engine. The car mounted 7G-TRONIC automatic transmission has a manual mode can be turned on when the traffic congestion so that the lowest fuel consumption function.

● careful planning “full” to reduce fuel consumption

Of course, in addition to the Mercedes-Benz engineers on the engine as much as possible “hands and feet” outside, in order to improve fuel economy, has also done a lot of other detailed work and improvements.

released from the Mercedes-Benz C-Class Blue Efficiency version we discovered that in order to reduce fuel consumption on a full range of cost-conscious. Of course, the first to reduce the curb weight, by switching to a special Mercedes thin windshield, and the new cast alloy wheels and other measures for the new car, trim down 32 kg. In order to overcome travelEnormous air resistance caused by fuel waste, improved aerodynamics performance, engineers and installation of guard at the bottom of the vehicle, while the suspension height is also reduced by 15 mm. Tire failed to “survive”, Michelin’s new low-resistance tires to reduce rolling resistance in maximum.

non-renewable petroleum resources to the traditional sedan existential crisis can not be avoided. However, currently used as a car battery-powered internal combustion engines for automotive new energy seems too early, then, what kind of green car is what we need to do? At least one thing is certain, and that is no matter what kind of scene, the engine power is still the mainstream car market, passenger car manufacturers should continue to develop new technologies related to the internal combustion engine and a series of technology to reduce fuel consumption. At this point, Mercedes-Benz BlueEFFICIENCY technology is undoubtedly at the forefront of the industry.
