Here we saw how the engines have evolves through the years. Changing with the times, to meet all the new stringent rules and regulations that come along. The sport is now designed to make engines with resemblances to the road cars. This means, that in one way or another, the technologies present here trickle down to our everyday cars slowly. But Definitely.
The modern Formula 1 engines are nothing short of a masterpiece. By the rules, these have to be a 1.6-litre V6 engine. They are turbocharged. Energy Recovery system is inculcated in it too. The newer engines have the Energy Recovery system. Here we have systems squeezing back the energy lost in the exhaust as heat and due to braking. These are stored in the battery pack and used when needed.
When broken down, the components look like this.
The Energy Recovery System (ERS) is a stepped up version of the Kinetic Energy Recovery System (KERS). Introduced back in 2009, KERS was here to stay. All cars had it, and drivers could use the system for a set amount of time every lap, in order to gain a potential competitive advantage over their rival. The ERS, has almost twice the power. In a KERS, where you harness the kinetic energy lost during braking, here you have the system broken down into two main sub systems.
The MGU-H and The MGU-K.
The Motor generator unit- Kinetic takes the waste energy caused due to braking. This is then stored In the unit, and used when needed. The MGU-K is only capable of saving 2MJ per lap. It can work the other way round too, by controlling the crank through sets of timing gears.
Unlike the MGU-K, this one doesn’t have any restriction regarding the energy that can be stored. The name may drive you into thinking that the energy is derived from the heat. This is far from true. The MGU-H acts by saving energy by varying the rotation of the shaft in the Turbo charger. It can slow down or speed up the shaft, through an attached gear train, thus eliminating turbo-lag. The MGU-H and MGU-K works side by side, boosting the power out-put.
The Engine regulations are set to receive a major face over in 2020. The current MGU-K and MGU-H systems are over complicated and have been driving the engineers crazy ever since their inception in 2014. The fact that MGU-K can work with the constant help from MGU-H only adds to this entanglement. Talks have been going on and will continue to happen for some time regarding the Noise produced by these engines. Some find it too mundane.
Great F1 cars from yesteryear to remind us of what we have lost
