N2 - Based on the structural characteristics of the double swirl combustion system(DSCS) and lateral swirl combustion system (LSCS), which used the shape of combustion chamber to generate swirl motion in the longitudinal and lateral spaces, respectively, a multi-swirl combustion system(MSCS) was proposed to generate a double swirling in the longitudinal and lateral spaces of the combustion chamber. For exploring the experimental performance of MSCS, the speed-characteristics of the multi-swirl (MS) combustion chamber at different injection angles were studied on a single-cylinder diesel engine. Experimental results show that the MSCS has the lowest fuel consumption and soot emissions when the fuel injection direction is aimed at the tip of convex edge. Compared with the speed characteristics of the DSCS, the brake specific fuel consumption and soot emissions of MSCS were reduced by 4~5 g/(kW·h) and 60%, respectively under the same operating conditions, indicating that the MSCS can effectively reduce the fuel consumption and soot emissions, thereby improving the overall performance of the diesel engine.
