Mercedes Benz F-Class
Edmunds.com recently took a closer look at the German ingenuity of Mercedes-Benz’s DiesOtto. Imagine the fuel efficiency of a diesel engine minus the rattle and without compromising its power. DiesOtto was first introduced at the 2007 Frankfurt Auto Show and featured in the Mercedes-Benz F 700. The F 700 was intended to be a research vehicle to demonstrate technologies that might be incorporated into future S-Class sedans.
It was termed as DiesOtto to honor Rudolf Diesel, who invented the compression-ignition internal combustion engine, and Nikolaus Otto, who popularized the four-cycle internal combustion engine.
DiesOtto achieves the diesel-like fuel efficiency and great performance through the new combustion strategy called Homogenous Charge Compression Ignition (HCCI). Edmunds.com said that HCCI “combines the technique of spark ignition when the engine is cold or accelerating with the principle of diesel-style auto-ignition under partial loads.”
Until the temperature and pressure rise high enough to ignite the mixture, a lean air-fuel mixture is compressed in the cylinder. HCCI technology then creates a flameless release of energy throughout the entire combustion chamber that completes the combustion process and promotes low temperatures. Fuel efficiency and low-temperature combustion is achieved by the HCCI engine with the help of the lean operation.
In the F700, the Mercedes-Benz DiesOtto engine works with a small gasoline engine, two-stage turbocharging, direct fuel injection, variable valve timing and HCCI.
According to Mercedes Benz, instead of manipulating the cylinder head, variable compression is achieved by physically influencing the crankshaft. DiesOtto’s project leader Günter Karl says, “We can adapt the compression ratio very well to the operating points, so we have good efficiency.” He continues, “Under part load we go as high as possible — higher than spark ignition but lower than diesel. At wide-open throttle we can go lower, so we have no knocking.”
With all the promising effects the DiesOtto has, many are wondering when it will be available in the market. Mercedes-Benz said it will be awhile before it is released since there are many things that need to be done. Günter Karl says, “We have a pressure transducer in each cylinder for closed-loop combustion control. This is absolutely necessary to get good transient behavior between HCCI mode and spark-ignition mode.” He also added that the complexity of the system may need “real physics in the ECU.”

Mercedes-Benz F700: the car that thinks
There are countless concept cars emerging every now and then in auto shows. These futuristic automobiles take on a variety of shape, size, and design, among others. Aside from their unique exterior features, people are likely going to look in on what the car can offer to them. Vehicles are made for the convenience of motorists and the German automaker Mercedes-Benz knows this. Mercedes-Benz F700 is the company’s latest find that can answer to both user and environment demands.
Although the Mercedes-Benz F700 is yet to be finalized, it thus look promising. Starting from the high-end Mercedes-Benz Parts installed in it. For starters, the vehicle is capable of adjusting to various road conditions because of its one of a kind headlights. These auto parts are equipped with laser sensors. With these sensors, the headlights function like eyes and survey the road surface. Once the needed data is gathered, the Benz F700’s control units make the necessary precautions for such road condition. The computer sends out messages, which translates to movements, to the the vehicle’s other parts. The wheels, which are the primary receivers of the information from the computers, perform the necessary action with the help of the water-powered pumps.
Another notable feature of the luxury company’s Mercedes-Benz F700 is the DiesOtto, which is responsible for making the vehicle ozone friendly. The special 1.8-liter engine is capable of of an advance production of power but with lesser noxious emissions, such as the Carbon dioxide and Nitrogen oxide. A catalytic converter further keeps the emission of the Benz F700 in a safer level. Despite the relatively low harmful exhaust, the engine prowess still translates to more power. The Benz F700, which has a ceiling speed of 210 kilometers per hour, can jump from zero to 100 kilometers per hour in just 7.5 seconds.
A Servo-HMI is also available in the Benz F700. In a small monitor, which is like a navigation screen, the driver can access his or her computer assistant. The user can upload his own inputs by only speaking to it. The intelligent computer saves and analyzes the audible data it gets. Directions to certain places, for example, can be stored in this intelligent navigation computer system of the Mercedes-Benz F700.
Clearly, this new concept car from Mercedes-Benz is more than just its good looks but it is more of the remarkable benefits it can provide to its user as well as the environment.

Mercedes Benz concepts and upgrades in Frankfurt Auto Show
Mercedes Benz owners and enthusiasts are surely looking forward for the upcoming Frankfurt Auto Show as 19 of the manufacturer’s cars, which are mix concept and updated cars, will grace the event this September.
According to Geoff Day, who is the director of corporate communications for Mercedes Benz, the luxury automobile manufacturer will showcase 19 new finds in only 15 minutes. This long list of cars will consist of concept cars and upgraded models. Hyrbrid cars will also grace the said auto show.
Most of the cars in the upcoming auto show will be likely from the F-class line of the luxury automobile company. The Mercedes Benz F700 concept car, which is a big luxury car, will be part of the show. The F700 may have drawn its name and some of the Benz parts from the Mercedes Benz F500 concept car, which was introduced in the Tokyo auto show four years ago.
A hybrid diesel powertrain and a night vision system will be the latest features that will keep the F500 above the ranks. Aside from the additional upgrades, the F500 is equipped with a 1.8-liter four-cylinder engine. What makes this engine superb is that it works like a diesel, but burns gasoline. Thanks to the spark plugs, the burn cycle of the gasoline is fired up. These abilities of the Mercedes Benz F500 engine makes it more fuel efficient. This powerful big-built luxury car is more than just the power because it also a pro-environment vehicle as it guarantees lower Nitrogen oxide emissions.
