since water is a good energy carrier, we just need to direct a small coolant hose to the brake caliper. This should be good for the future F1 cars.
You can have low pressure circuit for low temperature heat exchanger, but the moment it goes to the exhaust gas heat exchanger, it needs to be pressurized or else it will turn into steam. Pumping steam requires 10 times more power than pumping liquid water.
Considering that i draw oxygen from the pressurized oxygen tank, the peak efficiency is constant across engine load/rpm. it works very differently from regular car where the volumetric efficiency depends on engine speed, throttle opening, tuning, turbo, etc.
The vehicle needs to run with methanol or else the range is below the requirement. Assuming that we use the same composite tank for NGV, oxygen having almost twice the density of methane ensures plenty of oxygen to be available for every refilling. Other than that, high engine efficiency is a must or else the car wont be travelling far.
I used to work as a engine design engineer for a japanese oem and an F1 team. I have to say that once I develop compression ignition engine and understand its efficiency, i am a true convert of CI engine. Furthermore, i need the center of the combustion chamber for fuel injector, there is no place for a spark plug.
It's not as small as breadbox, but considering that the engine makes power in every revolution at constant peak torque even at low rev. I would say the displacement is really small.
