The average RPM range of our boring consumer cars, or heck, even our more performance fueled cars are sub 10,000 rpm. So how does F1 make an engine that revs to 20,000 RPM? And why would they want to? What does a higher revving engine mean for performance?

  • You are forgetting n°4: efficiency More rpm = More force due to friction. So, if you go super fast you will also lose a lot of energy. If engines wouldn't break and it was cheap to make them to rev fast, they wouldn't be economical in fuel consumption. Also, an engine with low rpm and everything else equal will last longer. That's why, when we can, we make rpm as low as possible. Boats and stationary diesel engines have very low rpm, like 100 rpm or so. They are VERY fuel efficient. One of those engines can achieve 50% efficiency (you move with half the energy contained in the fuel). Compare that to a normal car, with less than 25% efficiency.

  • Pretty good little vid... I try to explain to people that in road racing 5 grams (the weight of a nickel) off of each reciprocating assembly is worth more than 100 pounds off the entire weight of the car. - less power to accelerate the actual reciprocating assembly is more power to accelerate the car.

  • I do not like limitations. Ultracar: So, you have a problem with air density. Use it. So, you have a problem with rev limits... Make the piston sleeve work against the piston itself, as another piston moves it, increasing total compression, while opposing the sleeve to another piston. You add explosives to your mix to expedite propagation by passing the wave with excited microparticles. You eventually replace the idea with deuterium and go nuclear in a cyclical engine, but that is an auto supreme. The Ultracar uses an engine as a back up power source for emergency and as a starter. It also helps exchange exhaust gases into power. An Ultracar lubricant is liquid hydrogen. An Ultracars power source is the road, usually rail, but Ultracars are not restricted to these roads, but gain peak performance from them. A fuel cell for hydrogen provides partial power, the engine can burn nitrogen oxide, natural gas, or hydrogen. It requires water. The electrical engines load to orbital dynamic kinetic energy battery, which then displace needed energy through dynamic torque conversion. Dynamic as the transmission stages into variant torque loads in the toroid body. Transpositional tires then take the load of the drive train to a semi-conical tread, which allows the tires to act like a transmission but also lowers the chassis onto the rail while maintaining the same suspension system. Most trains use leverage systems to pick up chassis and change lanes or break line and separate for cars to go to destination exit without stopping the train. Autos are Independent, and equal to private jets, with equal legislative enforcement. The road is both power and communication. Yet both are also independent, as the locomotives are powered, yet the line is renewable and nuclear facilities. Lightning collected. The Ultracar is larger than a normal car, rating to a big rig transport truck or a tank. Its tires are cooled with hydrogen. Breaking returns energy to the vehicle, and respectively to the line. Emergency breaking is done with the use of the snow tread, and parking struts, while extremes in breaking hop the body down to full chassis dragging in controlled and extreme g chattering. While body panels blow away to display roll displacement air bags if the vehicle enters a frictionless or contact roll. High speed transit system for a new age of vehicle. The ultra car becomes the new nascar and reaches mach speeds. So with a Tesla valve engine combines with scramjet systems once velocity is reached and a few other tweaks to a first generation nasucar vehicle... Interdependent four wheel steering means your controls are augmented. Whole full manual is a nightmare of pedals clutches, paddles, and throttles, the mid electrically controlled vehicles are suited, while full auto controlled is available, yet licensing requires the use of mid formats. Which are redundant systems after the vehicle is taught by a full manual pilot. Push to stop, pull to accelerate, while pedals and throttles are reduced in number with automatic clutching. As the drive is four wheel independent, the need for dynamic turning, and suspension alterations are fully manual to fully automatic. Toggle controls for each wheel provide full coverage of wheel alignment. Again a full back stroke will provide dynamic breaking when over all tires, and opposite to each side. Forward stroking will promote a hop. Yes, full hydrolic control. m.facebook.com/story.php?story_fbid=10225850480029827&id=1267698847

  • Forgot one other important limiting factor. Air molecules only move so fast before you run into problems with mach numbers. Honda figured this out in the late 70's with their NR500 oval piston F1 motorcycle engine. The physics of air limits rpm to 24k so even solving for all these other problems (which they did with the development engines), you'll never fill the cylinders above 24k rpm.

  • Rod to stroke ratio and extreme light parts made from "unobtanium" is how F1 has achieved it for decades till they limited the rpms. A smaller displacement engine has a better chance from smaller swept volumes. HP = tq x rpms ÷ 5252 Tq is bore and stroke Rpms is rsr small bore 2 sides of the same coin to make HP Say i have a 03 636r @ 16krpms and a 03 1200 HD @ 6500rpms. .636 x 16000 = 10,176 liters displaced for 120hp 1.2 x 6500 = 7800 liters displaced for 79hp The engine 1/2 the size out displaced and made more HP through volumetric efficiency

  • all this talk about things bouncing, and stopping and starting, and never one mention of the speed of sound... air has to get moving. air has to stop and start at valves and ports. air starts to reach transonic speeds and it stops flowing. its mach speeds in ports that start limiting top speeds. flame propagation doesnt create force. its not the FLAME that pushes the piston, its the PRESSURE INCREASE from adding HEAT. the pressure wave travels far faster than the chemical reaction at the flame front. if it propagates too fast, pressure rises too high, things fail like firecrackers in trashcans... if it propagates too slowly, the reduction in pressure due to the receding piston outweighs the increase of pressure from the addition of heat from burning fuel. like in detonation, the pressure increase affects areas of the fuel/air charge that are not in contact with the flame front, causing the entire charge to ignite with a sudden catastrophic increase in pressure. the pressure travels faster than the flame front itself.

    otto leeverinkotto leeverink25 giorni fa
  • If you think about it the real limit is piston speed, which can't exceed flame velocity and which affects friction and thus wear. So shorter stroke means higher revs. But once you get below about 50cc the friction losses and other inefficiencies start to become excessive. A 250cc 5 cylinder 20 valve engine would have the balance, short stroke and low valve lift to exceed 20000 rpm but fuel injection and, I think, emissions, would make it a non-starter.
