The day-to-day human needs are strongly associated with the transportation and industrial sectors, which are influencing to deplete fossil fuel reserves. At this situation, the use of biodiesel in an efficient way is the only practical alternative to run compression ignition engines. The biodiesels fuel-borne oxygen may reduce carbon monoxide (CO), unburnt hydrocarbons (HC), and smoke emissions but increase carbon dioxide (CO₂) and oxides of nitrogen (NO_x) emissions. The scientists and researchers are starving to improve engine performance by reducing the most harmful NO_x emissions. Because of this, the author has investigated naturally aspirated single-cylinder unmodified direct injection compression ignition (DICI) engine. Two grams of mixed culture algal biomass particles are added in highly saturated coconut and unsaturated Karanja biodiesel fuels. The brake thermal efficiency of algal particles-emulsified fuels increased due to the explosion of biodiesel-surrounded algal particles after attaining autoignition temperature. The reduction in NO_x emissions is noticed with algal particles-emulsified fuels because the particles absorb heat from the combustion chamber.

人类的日常需求与运输和工业部门密切相关，而这正影响着化石燃料储备的枯竭。在这种情况下，高效运行生物柴油是运行压燃式发动机的唯一实际选择。生物柴油中的氧气可以减少一氧化碳（CO），未燃烧的碳氢化合物（HC）和烟气的排放，但会增加二氧化碳（CO ₂）和氮氧化物（NO _x）的排放。科学家和研究人员在挨饿通过降低最有害NO提高发动机性能的_X排放。因此，作者研究了自然吸气单缸未修改直喷压缩点火（DICI）发动机。将两克混合培养藻类生物质颗粒添加到高度饱和的椰子和不饱和的Karanja生物柴油燃料中。达到自燃温度后，由于生物柴油包围的藻粒爆炸，藻粒乳化燃料的制动热效率提高。中的NO的减少_X的排放，因为颗粒从燃烧室吸收热量与藻类颗粒乳化燃料注意到。
