N2 - An electrically assisted turbocharger is an advanced boosting technology that enhances the overall performance and reduces emissions of downsized engines. This paper investigates the effect of electric turbo assist [ETA] technology on a heavy duty, on-road diesel engine during steady state operation using a GT-Power 1-D engine simulation model. Two key findings have been observed: [1] Increasing assisting power at fixed torque, AFR and EGR rate values, leads to a reduction in pumping work, enhanced engine efficiency and reduced compressor mass flow, pressure ratio and turbocharger shaft speed. [2] Contrary to expectations, a fuel economy benefit was observed whilst assisting the turbocharger during high engine speed/full load operation and recovering energy at relatively low engine speeds and loads.
