چکیده

Abstract The reduction of CO 2 and pollutant emissions internal combustion engines (ICEs) keeping their performance close to the expectations is main driver research in transportation sector. To counteract global warming issues international governments set strict emission limitations foreseeing severe penalties for exceeding them. vehicle electrification surely helps match these stringent requirements, but a net can be achieved only if electricity from grid has low carbon content. This not case most part Countries where fossil fuels are still sources electric energy production. Thus, considering also higher cost vehicles, technological improvement ICEs assumes strategic importance this transition period. Among possible interventions ensuring achieve aim, efficiency enhancement ICE cooling pump one effective. As matter fact, it proven that replacement conventional centrifugal with Sliding Rotary Vane Pumps (SVRPs) lead an interesting decrease fuel consumption emissions. Nevertheless, design machines straightforward due complex thermo-fluid-dynamic phenomena taking place inside chambers. aspect even more critical wide operating range as heavy-duty vehicles. Here, high revolution speeds could provided satisfy flow rate requirements thus involving deterioration friction losses enhancement. Therefore, reduce speed needed by elaborate required rate, novel strategy based on volumetric capability presented. resulting approach was called Low Speed LS which prototyped experimentally characterized over conditions. indicated cycle measured better assess fluid-dynamic behaviour machine. experimental results show maximum 60% accordance best literature results.
