KERS - Kinetic Energy Recovery System

Williams Toyota is still considering running KERS (kinetic energy recovery system) in the 2010 Formula 1 season. This would conflict with the FOTA’s ban KERS in 2010 but Williams is not apart of FOTA as they chose to break ranks and sign up for the 2010 Formula 1 season during the FOTA vs. FIA battle.

The FOTA KERS ban is considered a gentleman’s agreement among the FOTA members but Williams has continued to develop their flywheel KERS system throughout the year as the technical regulations will permit teams to use the controversial hybrid system in 2010.

One FOTA member that may want to consider reviewing the KERS ban is McLaren, who have built a reliable system and used it in many races this season.

‘KERS Not Relevant to Road Cars According to Mercedes Engineer

KERS - Kinetic Energy Recovery System

McLaren-Mercedes is the only Formula 1 team that has run KERS (Kinetic Energy Recovery System) on both of its cars in every race this season. McLaren has developed two different KERS. One system is electric and uses batteries to store power, while the other is mechanical and uses a flywheel to store power.

A source inside the engineering department has stated that neither KERS system currently has an application for road vehicles at this time. McLaren managing director Anthony Sheriff recently said, “What’s important is that it’s pushing the envelope of battery technology to its limits and that has got to be good news.”

Brawn Reigns Supreme in Melbourne F1 Debut

APTOPIX Australia Auto Racing F1 GPThe Brawn GP debut in Melbourne, Australia couldn’t have been any better. The team finished the race taking the top two spots with Rubens Barrichello finishing 2nd and Jenson Button winning the race from pole. There is still a great deal of controversy regarding the diffusers used by the Brawn GP, Williams and Toyota teams. Ferrari, Red Bull and Renault protested the use of the diffusers stating they were illegal. The race stewards dismissed these claims and decided the diffusers were acceptable according to FIA regulation. It is believed that the protesting teams will follow up with their previous complaint claiming that while the diffusers are technically legal according to the regulations, they violate the “spirit” of the rule.

Will BMW Sauber have KERS for Australia Opener?

KERS - Kinetic Energy Recovery System

Nick Heidfeld has said that BMW Sauber has yet to make a decision on whether the or not they will be using a kinetic energy recovery system for the opening race in Melbourne, Australia.

Williams and Toyota have stated that they will not have cars with KERS on the starting grid. Red Bull has announced that they might postpone the introduction of their KERS system.

BMW Sauber is believed to have one of the most advanced kinectic energy recovery systems and has been one of the biggest supporters of the technology in Formula 1. The precise benefits gained by using the KERS is still not known. While the system delivers an instant horsepower boost at the driver’s command, the system adds an additional 40 kg of weight to the car, changes the weight distribution, raises the center of gravity, needs more cooling, and affects stability in braking. And then there is also the question of reliability.

“Reliability seems quite good and we are testing it quite often, not all the time, but on and off to understand the benefits that we will hopefully have,” Heidfeld stated on the Formula 1 website.

Vodafone McLaren Mercedes MP4-24 Photos, Press Pack and Technical Specification

Posted in Formula 1, Heikki Kovalainen, Lewis Hamilton with tags , , , , , , , , , , , on January 16, 2009 by autoracingpower

vodafone-mclaren-mercedes-mp4-24Ferrari was first with the F60, then Toyota with the TF109, now McLaren has introduced their new 2009 Formula 1 car to the world, the Vodafone McLaren Mercedes MP4-24. Judging from the pictures, Lewis Hamilton and Heikki Kovalainen look very happy with the design of the new car with huge smiles all around. As expected, the look of the car is very similar to the Ferrari F60 and Toyota TF109. A side-by-side comparison of the MP4-24 and last year’s McLaren F1 car may leave you believing that they are taking a step in the wrong direction aesthetically. Don’t blame McLaren. Channel all your rage towards the regulations. Let’s just hope the sacrifice in looks is forgotten as soon as the boys hit the track.

Aerodynamics

This year’s aerodynamic regulations were framed by the FIA and the Overtaking Working Group (helmed by Vodafone McLaren Mercedes engineering director Paddy Lowe, Ferrari’s Rory Byrne and Renault’s Pat Symonds) which met throughout 2007 in order to address the issues affecting passing in Formula 1.

The OWG’s influence can be most clearly seen around the front wing, which has been widened, and the rear wing – which is now more compact. Other factors affecting aerodynamics include the banning of ancillary appendages, the addition of driver-adjustable front-wing flaps and a heavily revised diffuser.

KERS

The MP4-24’s KERS device has been developed in collaboration with McLaren and Mercedes-Benz HighPerformanceEngines, which has been developing and refining the system for almost two years. The device enables the car to recover energy under braking, store the energy for a lap and release it when the driver presses a button on the steering wheel.

With a fully optimised KERS device’s output capped at 400kJ (discharging 80bhp boost for 6.7s per lap), the development team’s primary focus has already shifted to further improving the unit’s integration within the chassis in order to minimise performance loss elsewhere within the package.

An optimised KERS package can be expected to deliver a 0.3-0.5s gain per lap.

Winter test programme

With in-season track testing now prohibited, the MP4-24 will undergo an intensive winter programme at the following venues prior to the season-opening Australian Grand Prix on March 29:

Jan 19-22 Portimao Group test one
Feb 10-13 Jerez Group test two
Mar 1-4 Jerez Group test three
Mar 9-12 Barcelona Group test four
Week 12 Private test ahead of transportation to Melbourne

New F1 Scuderia Ferrari F60 Photos Released

Posted in Formula 1 with tags , , , , , , , , , , , on January 12, 2009 by autoracingpower

f1ferrari2The Scuderia Ferrari F60 is here, and it definitely has an updated look. Many of these changes have been mandated by the new regulations put into place by the FIA.

The narrow rear wing stands out as the biggest change. Other noticeable changes include the larger front wing and a lack of aerodynamic appendages on the sides of the body. The F60 also includes the new Kinetic Energy Recovery System, or KERS.

Flywheel and KERS – Racing Auto Parts

Posted in Auto Parts, Flywheel, Formula 1 with tags , , , , , , , , , , , on December 24, 2008 by autoracingpower

In a traditional vehicle, the flywheel is the large wheel connected to the crankshaft that provides the momentum to keep the crankshaft turning while power is not being applied. The momentum is created by the energy generated during the power stroke. This energy is also used to drive the crankshaft, connecting rods and pistons during the three idle strokes of the 4-stroke cycle. This makes for a smooth engine speed. The flywheel forms one surface of the clutch and is the base for the ring gear.

Flywheel and KERS

flywheel-kers

The upcoming season of Formula 1 will allow teams to incorporate the new Kinetic Energy Recovery System (KERS) system into their cars. This addition will essentially turn the cars into hybrids. KERS is not a battery electric hybrid technology that most people are familiar with. The recovered energy is stored in a rotating flywheel instead of being converted into electricity and then applied through an electric motor. The flywheel is approximately 5 kilograms and contained inside the car’s transmission. This stored energy in the flywheel can be used by pressing a boost button during certain times of the race.
