1.Bevezetés My name is Csongor and I will talk about the new hybrid power units of Formula 1 that were introduced in 2014. The new engines are six cylinder, 1,6-litres power units, and make around 600bhp (horsepower), and consist energy recovery systems. 2.Engine The internal combustion engine produces power through consumption of traditional carbon-based fuel, while electrical energy is harvested from braking and exhaust heat by two motor generator units. The two systems are called the motor generator unit-kinetic and heat. (MGU-K, MGU-H) These systems must work in harmony, with teams and drivers balancing the use of the two types of energy throughout the race. With the energy recovery system the combined maximum power output is around 760bhp similar to the output of the V8 engines of 2013. 3.MGU-K Under braking, the motor generator unit-kinetic (MGU-K) operates as a generator, recovering some of the kinetic energy dissipated during braking. The energy is converted into electrical energy and stored in the Energy Store. Under acceleration, the MGU-K is powered from the Energy Store or from the MGU-H and acts as a motor to propel the car. It provides an additional boost up to a maximum power of 120 kW. 4.MGU-H The motor generator unit-heat (MGU-H) is connected to the turbocharger. Acting as a generator, it absorbs power from the turbine shaft to convert heat energy from the exhaust gases. The electrical energy can be either directed to the MGU-K or to the battery for storage for later use. 5.Fogyasztás The new hybrid power units cover a grand prix distance using 35% less fuel than the V8 engines. In terms of consumption there is a double restriction, in order to make Formula One more environmentally aware. Since 2014 they have a maximum fuel load of 100kg, which is about 135 litres. The rate of fuel flow is also limited to 100kg/hour. However, at the maximum flow rate the cars could not even finish the race. This means drivers doesn't only have to save the tyres, but also have to manage fuel. The engines are limited to 15,000 (revolutions per minute) rpm, but they rarely exceed 12,000 rpm due to the reliability and fuel flow restrictions. 6.ERS This new Enegy Recovery system for F1 is a next generation uptake on the previous Kinetic Energy Recovery System (KERS). KERS involved capturing waste energy during braking, which is then transformed into electrical energy. When activated, the stored energy gave an extra 60kW (80 bhp) for up to 7 seconds per lap. With the new ERS system for 2014, drivers will not only have access to longer power bursts of 33 seconds, but double the power to the tune of 120 kW. 7.Stratégia How teams deploy the new power units on track? As a result, there is a complex exchange of energy going on between the components in the system, at varying (verijing ) levels of power over a lap. The use of the two types of energy needs an intelligent management. This is completely invisible to the driver as it is all controlled electronically by the control systems. A maximum of 2MJ energy per lap can be transferred from the MGU-K to the Energy Store, and a maximum of 4MJ per lap can be transferred from the Energy Store to the MGU-K. However, there are certain driver-operated modes to allow him to override the control system, for example to receive full power for overtaking. In qualifying the driver is able to use 100% of the allowed fuel flow and the entire energy budget from the battery store for his qualifying lap, but this case he will not be able to complete two flat out timed laps and will instead have to wait until the store recharges. 8.Összegzés In the beginning of the new era of Formula 1 there have been many techical issues with the new elements, but nowdays there are less problems with the new system.
