Abstract Global warming caused by greenhouse gas emission is a major threat in recent times. Carbon dioxide (CO 2 ) is a major source of greenhouse gas emission from CI engine. The present study aims to investigate the effect of pre-combustion, oxygenate and post-combustion system with biofuel blends in single cylinder CI engine on CO 2 emission. All the experiments were conducted in a single cylinder CI engine with 5.2 kW rated power at 1500 rpm at 50% and 100% load. Diesel is replaced with Karanja oil methyl ester (KOME) and both are taken as baseline data. Low carbon biofuel namely orange oil (ORG) was blended on an equal volume basis with KOME and tested. Zeolite based post-combustion capture system (ZPCS) and fuel ionization filter (FIF) as pre-combustion capture system was tested along with 20% methanol (M) blend with KOME-ORG. FIF electrochemically ionizes the fuel molecules and aids in quick dispersion of the ions for improved combustion. Hydrocarbon based biofuels are converted to carbon, hydrogen and oxygen ions, where hydrogen takes part in combustion and oxygen enhances the combustion process. At 100% load, CO 2 emission for KOME-ORG + M20 + FIF + ZPCS is 68% less compared to KOME. The combination also reduces NO and smoke by 48% and 51% compared to KOME at 100% load. The combined effect of FIF, ZPCS and methanol aided in the simultaneous reduction of NO, smoke and CO 2 emission.

电离系统生物燃料电化学转化对CI发动机及后燃系统CO 2 排放减缓的影响

摘要 由温室气体排放引起的全球变暖是近年来的主要威胁。二氧化碳 (CO 2 ) 是 CI 发动机温室气体排放的主要来源。本研究旨在研究单缸 CI 发动机中混合生物燃料的预燃、充氧和后燃系统对 CO 2 排放的影响。所有实验均在单缸 CI 发动机中进行，额定功率为 5.2 kW，转速为 1500 rpm，负载为 50% 和 100%。柴油被Karanja油甲酯（KOME）取代，两者都作为基线数据。低碳生物燃料即橙油 (ORG) 与 KOME 等体积混合并进行测试。基于沸石的燃烧后捕获系统 (ZPCS) 和作为燃烧前捕获系统的燃料电离过滤器 (FIF) 与 20% 甲醇 (M) 与 KOME-ORG 的混合物一起进行了测试。FIF 以电化学方式使燃料分子电离并帮助离子快速分散以改善燃烧。基于烃的生物燃料被转化为碳、氢和氧离子，其中氢参与燃烧，而氧增强了燃烧过程。在 100% 负载下，与 KOME 相比，KOME-ORG + M20 + FIF + ZPCS 的 CO 2 排放量减少了 68%。在 100% 负载下，与 KOME 相比，该组合还减少了 48% 和 51% 的 NO 和烟雾。FIF、ZPCS 和甲醇的综合作用有助于同时减少 NO、烟雾和 CO 2 排放。与 KOME 相比，KOME-ORG + M20 + FIF + ZPCS 的 CO 2 排放量减少了 68%。在 100% 负载下，与 KOME 相比，该组合还减少了 48% 和 51% 的 NO 和烟雾。FIF、ZPCS 和甲醇的综合作用有助于同时减少 NO、烟雾和 CO 2 排放。与 KOME 相比，KOME-ORG + M20 + FIF + ZPCS 的 CO 2 排放量减少了 68%。在 100% 负载下，与 KOME 相比，该组合还减少了 48% 和 51% 的 NO 和烟雾。FIF、ZPCS 和甲醇的综合作用有助于同时减少 NO、烟雾和 CO 2 排放。
