kinetic energy recovery system is a new technology used in the FIA F1 car, abbreviation KERS principle: the body through technical means braking energy stored and released by using as an auxiliary power in the car acceleration .
1. The kinetic energy recovery system defined
the KERS kinetic energy recovery system, is the abbreviation KERS.KERS kinetic energy recovery system (Kinetic Energy Recovery Systems) abbreviation. Its underlying principle is: the vehicle body by means of techniques braking energy stored and released by using as an auxiliary power in the car acceleration! Use of specific methods may mimic the acceleration button A1 to achieve.

2 kinetic energy recovery system F1 introduced
battery – motor kinetic energy recovery system diagram of a lot of people think F1 introduction of KERS is FIA to increase overtaking opportunities – to improve the competition excitement, suppress engine R & D – to control costs soaring and temporary move to take, which is completely wrong!
the automotive industry around the world are faced with industrial development and environmental protection this contradiction. Energy, carbon dioxide emissions, is no longer fashionable topic, but it stood in front of, and need for immediate hands-on problem-solving. Germany introduced the emissions of carbon dioxide per kilometer should not exceed 120 grams indicators, this indicator if it becomes legislation, will mean that a large displacement engine is no longer promising. At the same time, some cities even plan only allows the use of hybrid vehicles in the city center, which means that manufacturers in the development of the product, must ensure that their vehicles may optional hybrid system. By these two cases, we can see the high efficiency of environmental technology for the development of the automotive industry how badly. Nowadays, although the major manufacturers have never reached any consensus, but has been basically formed the default development ideas: start with a hybrid start, then the transition to a pure hydrogen or electricity. Only in this way can there be in the future automotive industry.
At this time, known for high-tech, the highest in F1 motorsport pyramid, if you ignore this social trend, will face the danger of being eliminated. FIA president Max – Mosley was in 2006, said: “The trend in the world is changing, you will see the most obvious question is about global warming in every part of the world, have a very prominent public movement. If we do not reform now, we will miss this trend, F1 will become obsolete and, ultimately, death. “
Some people might think that if Mosley is alarmist, but the status quo is F1 follows: 2.4 l V8 engine, 100 km fuel consumption up to 49KG, 19000 rpm speed limit without any reference significance for civil engines, built at a cost of a 1: 1 wind tunnel cost more than 50000,000 euros, excluding the cost of 24 hours a year of operation, a station changed the aerodynamics practical value is zero …….
It is clear that F1 technology development, and is completely out of touch with society, and with increasing energy and environmental issues, it is contrary to the direction of social development. In the past, F1 is known as a testing ground for the automotive industry, the birthplace of advanced civilian technology; and with the change of technology trends, it’s this feature has become increasingly weak! In this case, reform is imperative and urgent. Because no one has a social responsibility, would be the use of “outdated” technology, a substantial waste of energy, environmental hazards sports pay homage!
KERS F1 conform precisely this social trend, keeping the first step towards advancement.
3. The kinetic energy recovery system rules limit
In order to encourage and promote the development of KERS technology, FIA gave the team plenty of space to play. Released version 2009 F1 Technical Regulations, the FIA KERS only a few technical indicators made provisions, all other aspects are open. According to Mosley saying, KERS development is almost unlimited. The new rules below is only bound by the terms:
1, KERS system input and maximum output power shall not exceed 60KW, the amount of energy released per lap shall not exceed 400KJ.
2 racing during the refueling stop, not to increase the energy storage system KERS.
3 racing engine, gearbox, clutch, differential and KERS and all the activation mechanism, ECU control must be designated by the FIA ECU suppliers (ie, standard ECU McLaren provided).
