Mclaren’s new front wing at Singapore

As part of a big update to its car, McLaren introduced a new front wing at Singapore. The new wing has a totally revised stacked element, in fact the one element featured at Spa and Monza is now replaced by two seperate elements. The outer one is a simple, small two-element wing attached to the main front wing endplate. The wing itself has its own endplate as well, as indicated by an arrow.

The more inward part of the stacked element looks rather more sophisticated and connects to the wing’s base panel which is now even more curved. Contrary to previous McLaren front wings, the stacked element is now also decoupled from the front wing adjuster, the most inward vertical panel on the wing.


Also note that McLaren did not fit the rest of their update package to the car this weekend for reliability reasons. It will be introduced at the next race.

Common Rail

Bosch is the only company worldwide to offer common-rail systems for the entire engine spectrum, from passenger-car and diesel commercial-vehicle engines to large diesel engines. Bosch developed the MCRS modular common-rail system for large diesel engines that have high engine speeds, up to 2.2 megawatts of power, and over 2.5 liters of displacement per cylinder. The MCRS now extends all the advantages of common-rail injection technology to diesel engines, which in the marine market are used in cargo ships, ferries, and yachts. With the system, Bosch can help engine manufacturers meet their goals of complying with future emission standards for ship drives. Moreover, the use of common-rail technology cuts fuel consumption in marine engines just as it does elsewhere, offering economic benefits for ship operators.

Modular design makes MCRS flexibly adaptable for large diesel engines
The Bosch MCRS is a modular common-rail system without the separate high-pressure accumulator that, in conventional systems, provides each injector with fuel. The fuel accumulator volume in the MCRS is integrated instead into the high-pressure pump and the injectors. The injectors themselves are connected to each other via short high-pressure lines. The system is designed so that the pressure at the nozzle is constant and independent of the engine speed. Since there is no separate high-pressure accumulator, the system can be flexibly adapted to different numbers of cylinders, thus making it appropriate for everything from four-cylinder in-line engines to 20-cylinder V engines. The only thing that must be changed is the number of injectors and pump elements. Each injector is equipped with a solenoid ball valve to allow up to three injections per combustion cycle. The CP9.1 high-pressure in-line piston pump, which is controlled electronically and lubricated with oil, generates pressures of up to 1800 bar for these injections. Depending on the level of performance needed, the CP9.1 can be equipped with anywhere from two to five pump elements. To guarantee reliable operation and a long service life even when fuel quality is inferior, the high-pressure pumps and injectors have an especially solid construction. Appropriate engine control units for the MCRS include the Bosch EDC17 series.

Meeting future emission targets
In improving the MCRS common-rail platform to offer injection pressures of up to 2200 bar, Bosch is making it possible to comply with both current and future ship-engine emission standards – such as EPA/EU Tier 4 as of 2015 and IMO Tier III as of 2016. The MCRS will be available starting in 2014.

Chandhok has had a taste of the new circuit before any other driver

By Sarah Holt

Hispania Racing’s Karun Chandhok is optimistic the Yeongam circuit will be ready in time to host the inaugural Korean Grand Prix on 24 October.

Chandhok became the first F1 driver to run on the new track, completing 14 laps in a Red Bull car on Saturday.

"Everyone has been a bit doom and gloom about it but it’s actually not that bad," the Indian racer told BBC Sport.

"The organisers think it’s all within their timelines and are confident that it will be ready on time."

A final official track inspection will take place on 21 September, only 32 days before the F1 cars are due out on the Yeongam circuit for the first time.

There has been growing speculation as to whether the scheduled race will go ahead because of delays in construction, in particular to the track surface.

After running the rule over the circuit, Chandhok said there is still some catch-up work to do but added that the organisers believe the circuit will be ready for Korea to make its bow on the F1 calendar.

 

"If they do everything they have told me that they are going to do then yes [it will be ready on time]," Chandhok continued.

"They’ve got to a point now and it is almost like they are doing touch-up work.

"They need to put another coating of top surface on the asphalt, the kerbs need some work and there are a few bumps to sort out.

"The garages are finished and the pit buildings, which look over the sea, are enormous – I’ve lived in smaller houses!

"The main grandstand is finished although they need to put up other temporary grandstands because they don’t have time to put up any more permanent ones.

"Admittedly, the circuit isn’t completed yet but there is a circuit for us to drive around."

The Korean circuit is the only new venue on the F1 calendar this season and has been designed by Hermann Tilke, the man behind the layouts of the new tracks in Malaysia, China, Bahrain and Abu Dhabi.

And Chandhok has said the 3.49-mile Korean International Circuit should provide an exciting test for the drivers.BBC Sport – F1 – Karun Chandhok impressed by first taste of Korea track

Bosch eBike System

Bosch is publicly presenting its new e-Bike system for the first time at the “Eurobike” bicycle trade show from September 1st to 4th 2010. Numerous bicycle manufacturers will have e-Bikes fitted with the drive system to test at Eurobike and will begin delivery to shops in spring of 2011. The Bosch e-Bike system offers bicycle manufacturers a great deal of design freedom, which is reflected in the variety of models seen. Whether mountain, trekking or touring bikes, the widest-range of bicycle types are to be seen at the trade show and can be experienced on the test track of the show. The professional servicing of the retail trade will be taken over by Magura – a well known constant in the bicycle trade for decades – as the service partner of Bosch e-Bike Systems. Bosch sees partnerships with established market players as a way to understand the market and better service them. The agreement with Magura is already the second such partnership with known names from the bicycle field. The first such agreement was agreed upon with Cannondale at the beginning of 2009, so as to introduce the requirements of bicycle manufacturers in the development of the E-Bike drive system.
Bosch is presenting its e-Bike drive system on stand A6-305 at “Eurobike” in Friedrichshafen.

Modular Bosch high performance drive with refined power outlay.
The Bosch e-Bike system is made up of closely calibrated modular components. The Drive Unit, the Battery Pack including charger and the handlebar HMI (Human-Machine-Interface) control unit present a lighter weight with a powerful and robust high performance drive. Furthermore, it offers greater drive safety due to the lower-laying vehicle center of gravity. The compact Li-Ion battery pack, that can be fully charged in only 2 ½ hours (288 Wh) or 50% charged after only one hour, offers scope for individual creativity and is therefore available in different build configurations for frame or carrier fitting. Built with three sensors that measure speed, torque and pedaling cadence, the system deploys the instantaneously requested drive power in an efficient and comfortable way; nonetheless remaining unobtrusive so as to maintain the typical bicycle characteristics.

Drive characteristics that correspond to the type of bicycle.
The drive characteristics of the Bosch e-Bike system is programmable, allowing to set it up for a specific type of bicycle, according to one of four levels – named Eco, Tour, Sport and Speed. For example, the drive will therefore deliver its power in a more dynamic way on a sporty mountain bike than on a trekking bike set out for greater range. It is the bicycle manufacturer who decides which drive characteristics the e-Bike will have. In case they enable more than one of the four levels, the e-Biker will be able to select the appropriate level from the control unit of the drive system according to the situation.

The strategy of Bosch in the e-Bike market is based upon technological competence.
The proximity of electric bicycles to the social trends of energy-saving, E-mobility and health consciousness is of key importance to the world leading autotive supplier when taking the plunge into the sale of e-Bike drives. Bosch is investing in different fields relating to these long-term trends. E-Bike drives are an important part for the sustainable mobility concepts that point out the way for the future.
Bosch can furthermore bring its long-term experience in the construction of compact and efficient electrical drives, as well as powerful batteries to e-Bikes. This will allow the production of especially high-performance and variably adaptable e-Bike drive systems when combined with robust drive electronics and sensitive sensor technology
