But the waste exhaust gas could be run through a heat exchanger and heat the car and save the battery.
The Rotary ICE would require liquid cooling heat would be diverted through a 4 way valve to the vehicles cabin, recycling the exhaust gas heat as per VW Beetle proved very inefficient.
To enable the Rotary engine to behave like a diesel engine (i.e GDI) the fuel will have to injected directly into the combustion chamber as per modern diesel engine, you also need to maintain a fuel velocity speed between 80-110m/s for maximum efficiency.
I have only briefly looked at your link my brain is a bit exhausted at the moment, the waste gas would need to run a turbo to increasing the air pressure above 14.69 pounds per square inch (1 bar) to produce a cleaner more efficient burn.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
