Renault Scenic ZEV H2

Renault has very large projects in the electric vehicle, but he also sees further. In every sense, including that of having more autonomy through a fuel cell (CAP) powered by hydrogen. With a reservoir pressure of 350 bars, the autonomy of the Scenic ZEV H2 already reached 350 km, and although Renault has not done, it would be possible to put a reservoir to 700 bars of pressure, for bring to more than 500 km. The 350 bars nevertheless sufficient to validate the technology, more promising than any electric batteries, and with even more easily than Renault may not station outlet of hydrogen at 700 bars on its test centre. Renault Scenic ZEV H2

Renault Scenic ZEV H2The base used to develop these prototypes is well known is that the Grand Scenic. But there is a substantial difference between these protos hydrogen and a Scenic standard height. Renault has clearly not yet know-how Honda, which has launched production of the FCX Clarity, he had slightly (6 cm still) raise its Scenic to enable it to accommodate a technology for which he had, it is true, not been designed. There is also inlets different, a PAC to need more air an engine combustion, it has expanded those of Scenic.

But alongside this, to understand these differences, a surprising thing, a very small thing, the logo. The Scenic indeed, is Renault-Nissan badge. There are perhaps who remember the first prototype Renault PAC, a Laguna break at the end of the last century. It was conducted by the manufacturer french. While it is a collaborative effort of 2 marks Allied, which is not an evil, but emphasize that Nissan has provided the most important, namely the CAP and Lithium-Ion battery. Elements imagine that very close to those of Nissan FCV. Renault Scenic ZEV H2

Renault Scenic ZEV H2The architecture of the vehicle is divided into 3. It is under the hood the electric motor and transmission (one report, move forward or backward), accompanied by any power electronics that control the car, and an air compressor. The air is sent to the CAP, located in the center of the car, under the front passenger seat, which combines with hydrogen from a tank located under the floor of the trunk, near the battery. This architecture is not ideal. The solution Honda or GM, to use a large central console, to house elements, is definitely more skilled.

But these manufacturers have chosen to develop a dedicated architecture, where Renault has chosen to adapt the existing platform of Scenic. With this constraint, it has been fairly successful, since habitability is fully preserved. Only the trunk is somewhat reduced, by a raised floor. It is therefore aboard a Scenic normal, ie a well-designed car at the interior, albeit with a modified instrumentation, or more exactly appropriate.The revolution and the regime gives the electric motor, the gauge gasoline has become an indicator of pressure hydrogen, while the indicator energy is available on the navigation screen. Renault Scenic ZEV H2

Renault Scenic ZEV H2The electric motor has a power of 90 kW, which seems sufficient, but not exciting as long as this Scenic hydrogen is 300 kg heavier (!) That the diesel model series (dCi 130). It is 1850 kg on the scale, and much. It may still, of course, appreciate the flexibility unmatched electric motor, but with a top speed of 160 km / h and an acceleration of 0 to 100 km / h to 14 “65, there is no What complacency. It is true that there is no need for athletic performance to validate and test the technology and hydrogen CAP, but in competition, the GM Sequel goes from 0 to 100 km / h in under 10 seconds.

So if this prototype is a good effort on the part of the brand in diamond, which was late, it shows that Renault follows, but remains behind the leaders of hydrogen as GM, Honda or Toyota. To compensate, we look forward to the future electric Renault. The earlier, or Kangoo Express, had not been very successful.But that was partly due to the network, which had been unable (or unwilling) to make the necessary effort to promote them. With a strong commitment by Carlos Ghosn himself for future Renault and Nissan electric cars Series scheduled for 2010/2011, we do not have many doubts they are the best globally. Finally green rimera with Renault!

The new Toyota FCHV drive north of the earth

Honda has announced that mass production of fuel cell vehicles “clarity” is a feeling of future automotive debut in style. F1 race, similar to rival Honda fuel cell vehicles will also work hard, because Toyota can not keep silence. It would be, F1 funds to take over the development of fuel cell vehicles, Toyota’s recent trend that is worrisome?

Previous reports, as the Hokkaido Shibetsu Toyota’s vast small test course “iQ” we were able to hold the steering thing, but when this latest fuel cell hybrid vehicle, “Toyota FCHV-adv (Fuel Cell Hybrid Vehicle – advanced) “could also test-drive.

Toyota FCHV is like Honda’s new platform is a nonissue because we have not given, but the contents have been steadily evolving. Toyota to develop a lot of people see the situation is quiet SUV “Krueger”, already has completed the production and sales of the model may be used by. Somehow it felt old. Hokkaido test-ride event Okamoto, who was vice chairman of Toyota’s “do not always make the body, so please be patient,” he added. The most important thing is the performance of fuel cell reliability of the cost.

Asahikawa in Shibetsu test from the 100 km road course FCHV to drive. ETC with Krueger also enjoy the highway. The passenger seat Ishiguro, Chair of the developers sit.

he fuel-cell vehicles have a hybrid system. Nickel-metal hydride secondary battery and fuel cell body (stack) combination.Stack becomes easy to replace internal combustion engines. In other words, you accumulate savings to electric box-like secondary battery, a stack of electrical power generation system is paired with the other two. The Prius has the same meaning.

Toyota FCHV-adv

300 ~ 500km rather than the medium-range game is?

Asahikawa in Amsterdam to leave. And a stop signal, fuel cells will automatically shut down. Unlike the internal combustion engine stops, originally quiet stack is shut down, the feeling is not idle stop. And when the brake energy regeneration, but can not originally high energy efficiency (energy consumption is low), meaning the recovery is extremely high. Less money from a large portion of your change.

But the model is the relationship between secondary battery capacity, many of the regenerative energy recovery can not. The next step is to practical use lithium-ion batteries until the recovery rate is low. Therefore, even if actually running the engine brakes feel very strong. This recovery rate is low.

700 low-pressure hydrogen gas fuel is using, but this time as there is no hydrogen station areas, how the hydrogen to fill it out? So the idea is hideous mobile hydrogen station. Iwatani International Corporation of Japan has undertaken a hand.

Honda has 350 hydrogen gas pressure system will be stuck with the world becoming a standard atmospheric pressure is 700. Kruger Toyota FCHV SUV is a vehicle height is high, so high-pressure hydrogen storage tank to the floor. Highly efficient hybrid system and a combination of the stack, and 700 with a low-pressure fuel FCHV is a range of more than 500 km that is secure.

Ride in the passenger seat while driving Organizer Ishiguro, a variety of stories blast. Osaka to Tokyo’s Odaiba hydrogen from the station until without refueling (lubrication oil so the word is also incorrect) to cover the whole of it. Also, Toyota will run only secondary battery EV (electric vehicle) and fuel-cell vehicles to differentiate how the idea? The answer is that distance and duration. For example, 200 ~ 300 km run in the EV, 300 ~ 500 Km of fuel cell vehicles, 500 ~ 1000 Km of internal combustion engines and hybrid might be considered.

With an output of 90kW fuel cell

Honda has stuck with the 350 Pressure is the reason for this is to think of hydrogen filling. Excessive pressure of 700 and it is not practical. Honda is certainly plausible explanation.

Pressure 700 manufacturers from around the world to believe that immediate standard is 700 atmospheres, you can study, because we can reduce later. Ishiguro, as Chair of Toyota’s my opinion “about 500 atmospheric pressure at the optimal solution might have,” he said in the study stage in the high hurdles mean that there would be a good idea.

Since evolution of the FCHV is very cold areas where there is work that has been confirmed. Organizer Ishiguro himself all over Canada and the Arctic Circle, close to the cold-start test and the minus 37 degrees and it was confirmed that the work.

Get on the freeway and the performance of the newly evolved FCHV shock. 90kW higher output in the design of a new generation of high-performance fuel cells to beat him hurtling to earth in the north. “Dental and well” is an expression of literary, but it is quiet, tire and wind noise, the lone road only hear the sound.

Output 90kW how big? Have been installed in my home for a family of fuel-cell stack is only 1 kW. This compared to how energy is used vehicle or vehicles that would be understandable. Toyota’s fuel cell vehicle that is one of about 50 households MAKANAE power to them.

Hydrogen energy is becoming a source of intuition

I felt attracted to fuel-cell cars is almost the same time Toyota and Mercedes are the future of automotive fuel cell vehicles is a powerful message out from the start.

Attracted more than anything is that the hydrogen fuel. It was Mechanical Engineering students to teachers is a pioneer in the hydrogen engine. The premises of a prototype of a hydrogen engine vehicle is “PUTSUNPUTSUN” BAKKUFAIYA out with a big, run, it was left to the head. Is the car’s hydrogen energy and intuitive feeling was that instead of hydrogen-burning hydrogen engine, hydrogen fuel cells, hydrogen power can be interested.

My steering wheel is the first time in 1996, “RAV4″ made the EV-based early stage. Tokyo Gas, the site of a test ride. At that time, technology is the hydrogen-absorbing alloy metals (rare earth) type. So I ran and the weight is too groggy to remember.

But remarkable progress has been made in 2001, the Prius hybrid system that combines the same. And finally minister in December 2002 to develop fuel-cell vehicle certified by the Cabinet and Government / leasing companies have started selling.

Toyota’s efforts to follow this has been the Honda and DaimlerChrysler and General Motors (GM). Toyota will further fuel cell bus in collaboration with Hino Motors, Daihatsu and Nissan’s fuel cell car developed. Honda differences in company size and the development of the road map is somewhat different.

Fuel cell vehicles and electric vehicles colleagues in the broad sense

The FCHV-adv hydrogen tank is two-fold increase in the fuel economy mode and that can travel 840 km. The safety of the car violently crushing a hydrogen tank would also be protected so strongly built on it.

What is worrisome is sent to stack the hydrogen leak of hydrogen in the pipeline. The FCHV hydrogen exclusively from side to side, before and after the crash sensors to place the cabin at the top of the stack and the hydrogen tank and a hydrogen leak is equipped with sensors to detect. As a result, hydrogen and hydrogen tank leak may have automatically closed the valves.

Japan in September 2008 from the sale of some government agencies to lease began. Priced at 7,760 US$ per month for 30 months and lease expensive, but still, someone is not going to use the attention of the world.
Toyota, Honda and Nissan continued to fuel cell vehicles to show for his attention, but I wonder about the electric vehicle is equipped with a lithium-ion batteries are completely separate working on it. Fuel cell vehicles and electric vehicles in the broad sense of camaraderie. In that sense, the Japanese fuel cell vehicles and electric vehicles, the roadmap is a different feeling in there?

Electric vehicles and fuel cell vehicles or energy from the viewpoint of the jurisdiction of the Ministry of Economy, Trade and Industry, Japan’s fuel-cell vehicles to conduct field trials “JHFC (hydrogen fuel cell demonstration project),” fuel-cell-related private companies Making “FCCJ (Fuel Cell Commercialization Council)”, and the spread of electric cars is another program that is working hard to understand.

Withdrawal from fossil fuel and renewable energy to achieving a sustainable society is possible. Ishiguro, Chair of the sides to listen to Toyota’s technical department in the diversity of electric drive technology while fully understanding the technology and scrub.

Mazda Motors renewed palette

With a renewal of its engine range and light engineering will the Mazda car manufacturers by 2015 the consumption of its car models by 30 percent. The first step is a newly developed 2.2-liter diesel engine, the Mazda6 in early 2009 premiere will celebrate. The engine is on the German market following the current 2.0-liter self after Igniter replace and in three performance levels of around 96 kW/130 hp to 136 kW/185 hp offered, with the top version of the beginning. Also still 2009, the engine also the range of only a thirsty petrol offered CX-7 SUV. With an average consumption of 5.6 litres per 100 kilometres in the Mazda6, the 185-hp version on the same level as its only 103 kW/140 hp predecessor.
Mazda x16
In addition to the consumption, it is primarily the smoothness and low noise level at high speeds, the new diesel concerned. During the trip on the highway, the top Mittelkl├Ąssler version of the Mazda6 easy ride in responding promptly to every command acceleration and can be hardly anything to hear from. Only when stop lights attentive driver hears a soft-on-ensuring round-nails. The acoustic restraint, inter alia, through improved insulation of the engine block and a new balance shaft.

The dimensions of the unit has undertaken the two-litre engine, little changed since the longer stroke offset by shorter connecting rods. Even the turbocharger of the common rail diesel, the engineers hand. The shovels were for a better passage and slightly bent. A revised injection increases the cash injection by 200 to 2 000 bar, the number of injections and the fuel and the Einspritzzeiten.

In addition to the already in the works from the band Hiroshima current 2.2-litre diesel 2011, there will be a further developed by Mazda self-ignition. By 2010, a new rotary engine with hydrogen drive under the name 16X on the market. Under the Spritsparprogrammes the Japanese also have a start-stop automatic, the new Mazda3 will celebrate its premiere. The startup process after the stop lights should be submitted as SISS (Smart Idle Stop system) twice as fast as go for products of competition because in addition to the launch by generator at the same time also the first ignition in one of the piston. At the same time, a reduction in vehicle weight of 100 kilograms and more for all new models from 2011. Dies soll vor allem durch die Verwendung neuer Materialien erreicht werden. This will be primarily through the use of new materials.

FORD EDGE HYSERIES DRIVE

The cleanest SUV in the world

With fuel cell cars there are – at least as prototypes – almost like sand on the sea. Buy but these cars can still nowhere. However: There will be further researched. Almost all development departments of car manufacturers werkeln in a clean power package, which consists of hydrogen on board the cars for the power an electric motor. The second major trend for a clean future is the battery-powered vehicle that is his power – such as just so popular Tesla Roadster – at the outlet tanks.

Ford now goes a step further: Both technologies were in fact the first time together in a vehicle. The prototype is called Edge HySeries Drive, and SPIEGEL ONLINE, the models around the Ford Research Center in Aachen first time. It is the first serial plug-in fuel cell hybrid – which comes under the eierlegenden Wollmilchsau research vehicles already pretty close. On short-haul runs the single unit with power from the outlet. And if the charge of the lithium-ion battery is low, the onboard computer raises the fuel cell to the battery to eat.

Nur das M├Ąusekino f├╝r die Energieflussanzeige in der Mittelkonsole, der Strom- anstelle des Drehzahlmessers und nat├╝rlich der Blick unter die Motorhaube irritieren: Statt des konventionellen V6-Triebwerks steckt dort ein ├╝berraschend kleiner Elektromotor mit umgerechnet 88 PS. Only the mice cinema for the energy-flow display in the center console, power instead of the speed gauge and, of course, look under the hood irritate: Instead of the conventional V6 engine there is a surprisingly small electric motor with converted 88 hp. The same unit is also working on the rear axle – the Edge shall retain the four-wheel drive and comes up to 176 hp.

At the wheel of the car does spectacularly unspectacular. Because of the chemical factory and the power plant on board the driver feels nothing. Ever need to sharpen the senses when the SUV on the future is how each electric car, this Edge almost completely silent and accelerated with the two 230 Nm times faster than anyone expected. Although the alternative propulsion technology around 400 kilos on the scales and it takes only one course, the car is therefore almost sparkling. It accelerates in 9.4 seconds from 0 to tempo 100, in city traffic keeps loose, and also on the road you can feel hardly any difference. Only on the highway was really busy – because at 140 km / h for the electric motors final.

The fact that this Edge runs differently than a gasoline car, you can feel even when Brakes: First, because then the front electric motor acts as a generator and the battery feeds. And secondly, because the mass powerful and pushes the car only to press to stop. “But that is only a prototype,” a companion excused the unusual braking.

With a battery filling, the Edge on a range of 40 kilometers. And the 4.5 kilograms of hydrogen in the tank full enough to power for another 320 km to produce. Even the gas at a pressure of 350 bar stored. Doch arbeitet Ford an Tanks, die 700 bar verkraften. But Ford is working on tanks, the 700 bar handle. Then would the range to 450 km climb and the Edge to everyday car. Most customers, however, have probably never been as one of the rare hydrogen filling stations. “Many go on the day less than 40 kilometers,” says project manager Roland Krueger. “Who the Edge in the local garage or in the company parking lot at the outlet depends, it has quickly full.” The loading process takes four hours.

The combination of large and small battery fuel cell has two advantages Kruger. “First, the range, and secondly, the fuel cell in a very limited operating range. Therefore, it is less complex and thus little cheaper than other systems.” This is particularly important for Kruger. Because the price is in addition to the lack of infrastructure for hydrogen remains the biggest hurdle on the way to series maturity of this technology.

“The technical problems we will be in seven or eight years under control,” says Krueger, with a view to cold start behaviour, performance and durability of the fuel cell. But the costs were pressed, dauere it safe even longer. “Finally, we need the price nor to reduce at least one point.” Even then, a fuel cell car close to the pain threshold of what the customers today for a Ford to pay. But in recent months Kruger sees the cost issue increasingly relaxed: “The more expensive gasoline and diesel are, the easier it is for us later, the customer to change.”

Suzuki SX4-FCV

The prototype hydrogen-Suzuki SX4-FCV presented the Japanese manufacturer at the G8 summit on the peninsula of Hokkaido. The small cars will be on a high-performance fuel cell and excess brake to accelerate use. The five-manufacturer creates a maximum speed of 150 km / h and has a range of 250 kilometers.

270 km rather than the current 160 km per tank is now also the prototype Mercedes-Benz A-Class F-Cell “plus” course. This has the Stuttgart manufacturer on a trial ride from Berlin to Magdeburg Environmental Forum demonstrated. The range increase of almost 70 percent is through increased compression of hydrogen. The new technology is also in the B-Class F-Cell to use and a range of 400 kilometers.
