- M​y SF90 Stradale configuration. Doesn't really relate to the article at all but it's pretty so I don't care.

T​he ICE is inefficient, how can we combat that?

W​e know that they can be CLEANER than EVs, but how can we make them more efficient?

A​n ICE car, when powered by Synthetic fuels has potential to be fully carbon neutral, and prices are becoming more viable. We all know that by now. However, there is an issue with the ICE that can't be combatted by the fuel source. That is its inneficiency. Over 3/4 of all energy produced by an ICE is wasted. And a load of that is heat. This actually means they contribute to global warming as much as a BEV. A BEV uses nearly all the energy it produces.

T​his is a serious issue. You can't go around wasting that much energy. There are two ways we can counter this: one, change the way an ICE functions or two, put that energy to use. As a petrolhead, I wouldn't want to change the ICE as far as is possible, so I am thinking of solutions for the second option.

O​bviously, I have been thinking about what in an ICE car could do with a bit more energy or heat. I came up with an idea that heat could be transferred to the brakes. This might sound bad but hear me out. Due to convection currents, heat would circulate around the brakes at an even pace meaning the brakes would always be at a neutral temperature. This would be an improvement in terms of safety and maybe for track cars would improve lap times.

I​'ve had about a bajillion other ideas of similar principles that I can't be bothered to write down. Therefore I set you this challenge: find out a way of using the excess energy in an ICE car. The best idea wins the "mind blown" thingy that I will buy you with my own tribecoins. You are only allowed 1 post but you can put as many ideas as you want in that comment. The deadline is on the 4 March 2021. I know, sounds cool right. So put your solution in the comments!

  • As you mentioned heat is one of the biggest wastes of energy in combustion. There are parts of cars that need heat to work, like the heating system. It would have to be filtered in some way to stop the gases, but air filters already exist. Another way for this heat to be used is to turn this excess heat to create electricity, to charge batteries in the car or hybrid systems, this works with thermoelectric material when you have one side thats hot and the other is cold (google was used for that bit). Anyway, that creates a gradient in which electrons will flow. this is then used to provide power to parts of the car. What this means is that electric motors can be mounted on one of the axels, then they can be partly powered by our engines. Probelm slightly solved.

    • Yeah. Hybrids make sense. The theory has been proven with power being sourced from the heat of brakes. More heat being used equals more power and we all want that. It's even used in a few "self charging hybrid cars" that are relatively...

  • I think Christian von Koenigsegg know how to do it

  • I can’t be bothered to spend tonnes of money and time so I’d just use an electric motor with fuel cells (which are less efficient then batteries but are lighter)

    • Yeah. I think that could be a solution in the long term. If fuel cells could become sustainable eventually then that would be pretty damn close to no emissions.

  • They are currently using heat capture technology on F1 cars. It will trickle down. That needs to happen quickly.

    ReGen brakes. Stop wasting the energy in the form of heat. Capture the energy and utilize. Hybrids do this well. Make adaptations for older cars that are not insanely difficult or expensive to install. On EV's they could add capacitors to use part of the energy to store it for a boost when needed. KITT anyone?

    AC units convert heat to cold by generating more heat. Capture this heat and use it along with this exhaust heat. Convert it to electricity and send it to the batteries.

    In hot climates are ovens. Capture that heat! It too can be converted and harnessed. Otherwise it's an AC unit making heat to cool the inside down for the occupants.

    Engine heat that needs to be removed via side vents or hood vents. CAPTURE THAT HEAT. Use it.

    Now we have reused cabin, brake, engine and exhaust heat. That leaves only the heat generated by the shell of the car. That too can be converted and used.

    Now we have one cool car!!

    Switch systems from belt driven to electric and use this energy. That does what? Makes that ICE more efficient. Add in the FreeValve tech that is being developed by Koenigsegg, which uses electricity. That makes ICE even more efficient. Driveline loss is 15%. Move to a direct drive system and eliminate this loss or at least reduce it further.

    Lubricants. This is another area that can improve ICE efficiency. It's always in constant development. There are many that are better than traditional oil. They just cost a lot more. Ramp up production and bring the cost down. Figure it out, yo.

    Fuel. This is yet another area that can be further developed and Porsche is working on it. So is Mercedes. It's still prohibitively expensive but that can change.

    That's about all I can think of for now.

    • The general consensus is on regenerative brakes and hybrids so far. It would improve performance and maybe could mean we could have a more refined driving experience. A more direct system using electricity could be powered by the heat...

  • Today I heard of something called a 6 stroke engine, I haven't had time to research it but it seems interesting, but complicated. I could just be annoying and say use an electric motor though.
