How does F1 engines work?

Formula 1 engines are at the front of technology for internal combustion engines today. They are 2.4 liter V8 engines, with an operating range of 2000-20000 RPM. Like most car engines they have pistons connected via connecting rods to a crankshaft, they have a transmission and a clutch, as well as cam shafts and valves. Current F1 engines are naturally aspirated, and are not turbocharged. In order to produce 900hp, these engines must be capable of revving very high, 20,000 revolutions per minute to be exact. To do this these engines can not use conventional valve springs, but instead used compressed gas to return the valve to the closed position. Apart from that, and a few differences in some part locations such as the clutch, an F1 engine works just the same as any car engine.
