Bowman Power Group Ltd (Bowman) has conducted emissions trials on a gas fuelled generator to investigate the effect of using its Electric Turbo Compounding (ETC) technology on unburnt hydrocarbon (UHC) emissions. Initial findings indicate a 25 – 50% reduction in UHC emissions.
This was achieved by reducing the scavenging pressure in the engine cylinders, almost entirely eliminating fuel short circuiting and also reducing the release of non-combusted fuel.
To achieve this level of reduction would typically require long research and development periods for ‘in-engine’ solutions by an original equipment manufacturer, followed by intrusive and costly engine modification – difficulties avoided with the new technology.
