What they said: “While Bowman’s competitors have introduced mechanical turbo compounding that converts the exhaust gas into mechanical energy that is fed back to the crankshaft, the exhaust heat recovery system from Bowman Power is unique in its ability to convert some of the heat energy from exhaust gases into useful electrical energy. Running the turbo generator at controlled speeds, which is one of Bowman’s pending patents, optimises the efficiency across a wider range of engine conditions and delivers significantly higher fuel efficiency, thereby having an advantage over the mechanical turbo generators from competitors.”
