What Is Mgu K in Formula 1

What Is Mgu K in Formula 1

The ERS system of an F1 car is used to recover what can be called wasted energy and use it to give the car a power increase of several hundred horsepower on each lap. It consists of many different components, all of which are part of the car`s powertrain. The two main components are the motor generators, the MGU-H and the MGU-K. So we need to think about what happens to energy in a car when it`s driven. The engine uses fuel and oxygen to generate mechanical energy through combustion. This is the result of the chemical energy of the fuel and oxygen that is burned, and the mechanical energy of the pistons is converted into kinetic energy in the wheels that pushes the car forward. Which seems strange, let`s say, blame Porsche for getting rid of MGU-H. They`ve already built one – he`s won Le Mans three years in a row, in the 919 Hybrid LMP1. But everything that makes everyone agree at this point. The MGU-K is the more complex of the two systems. As I said, when wires are placed in a rotating magnetic field, a current is generated. The faster the engine runs, the more power is generated.

The MGU-K consists of an engine, similar to the MGU-H. However, in this case, it is connected to the crankshaft, which converts the movement of the piston of the engine into the rotational movement of the wheels. Instead, its main goal is to do what the MGU-H does and harvest the “wasted” kinetic energy from the retardant wheels and convert it into electrical energy that can then be sent to energy storage. From there, it can be sent both to the turbocharger compressor and to the wheels themselves when the accelerator pedal is depressed, giving the car that massive power boost. ERS stands for Energy Recovery System and is a fairly new innovation in the world of Formula 1. First appearing on the scene in 2009, it has become an integral part of the powertrains of F1 cars over time. So what are MGU-H and MGU-K, and how do they work? The French engineer then explained what the MGU-H, the unit connected to the turbocharger, is. The MGU-H is more of an F1 thing. We started to see a similar device in production cars. It`s called the E-Turbo and it`s designed to run the turbocharger at low revs. The MGU-K is very similar to what can be found in so-called hybrid production cars,” Taffin said at the Canadian Grand Prix in Montrãal©. In Formula 1, we have an electric motor connected to the petrol engine.

During braking phases, it recovers energy that is normally lost by heat. We now recover much of this kinetic energy, which is then stored in a battery. The MGU-K can work both ways: to recover or provide energy.â Where the powertrain differs from that of your road vehicle is in the power they can provide to cars. They are capable of reaching more than 1000 hp, which is a huge amount of power for a car that weighs less than a ton. The engine itself produces about 700 hp, with the remaining power coming from the engine`s generators that this article will explain. These devices generate and use the energy stored in an additional energy storage (ES) or energy storage (ESS) system, which is essentially a large lithium-ion battery. It is regulated to weigh between 20 and 25 kg. They are also regulated in terms of how much energy they can store and supply. When the driver releases the accelerator pedal, the engine stops working so hard and there is much less exhaust coming out of the waste barrier. This is not enough to turn the turbine, so the compressor also stops turning.

This is good because the engine does not need additional power when the driver passes more slowly. The problem is when they walk on the gas again.

The MGU-K converts the wasted kinetic energy of the decelerating wheels into electrical energy that can also be stored in the vehicle`s energy storage. The two work together to give the cars massive performance gains. Battery heat and recovered kinetic energy can be consumed immediately if necessary or used to charge energy storage or battery. “The output force of the stored energy is now taking place almost all over the round,” Taffin confessed. “We have achieved an excellent level of overall efficiency. Today, the MGU-K is capable of producing almost all of the 120 kW rounds, which corresponds to 160 hp. As soon as the driver presses the accelerator and we are no longer limited to grip, he brings out all the power. It is no longer whether the driver wants to use it or not.

Power is available. Everything is controlled automatically. In 2014, Formula 1 introduced new technical regulations that required all engines to be turbo hybrids. Turbocharging is a way to use exhaust gases to run a compressor that feeds more air and fuel into the engine cylinders. Hybrid technology uses an electric motor to support the gasoline engine. This extra resistance that the motor must overcome to generate electricity requires a lot of kinetic energy. Fortunately, it can remove this kinetic energy from the wheels, which it does very quickly. .
