ABSTRACT The quest for sustainable energy solutions has driven extensive research into biodiesel derived from renewable sources such as soybean oil and algae. This study aims to optimize production algae using transesterification pyrolysis processes. Additionally, it evaluates the performance emission characteristics of these biodiesels in conventional low heat rejection (LHR) engines enhance understanding processes their impact on engine emissions. Soybean were used feedstocks via pyrolysis. produced biodiesels, specifically methyl ester (SBME), (ALME), pyrolytic (SBPO), tested both LHR engines. Performance metrics brake‐specific fuel consumption (BSFC), brake thermal efficiency (BTE), exhaust gas temperature (EGT), emissions (CO, HC, NOx) analyzed. SBME20 blend demonstrated superior with lower BSFC, higher BTE, reduced CO HC compared ALME20 SBPO20 blends. However, NOx due increased combustion temperatures. engine's enhanced environment improved efficiency, particularly SBME20, which exhibited best overall profile. concludes that is most efficient environmentally friendly engines, highlighting potential a viable feedstock production. Further optimization required achieve comparable levels.

Thermoelectric generation (TEG) is a solid-state technique that efficiently captures waste heat from the exhaust of internal combustion engines. Heat pipes are passive energy recovery devices work with minimum temperature decrease, making them very efficient. TEGs and distinguished by their absence mechanical components noiseless performance, relying solely on thermal for operation. This research examines practicality combining device thermoelectric pipe (TEG–heat system) to capture utilize wasted stationary diesel engine operates in dual-fuel mode. The uses cooking oil methyl ester as pilot fuel introduces biogas (0.75 kg/h) an induction fuel. performance system was evaluated conducting experiments at different loads, specifically 1, 2, 3 kW. aimed analyze impact integrating into system. findings suggest incorporating generator greatly increased difference between modules. However, amount supplied modules reduced exchanger lengthened. In summary, integration TEG–heat has shown ability produce additional electrical power exhaust, hence enhancing efficiency.

Abstract The study investigates the performance, combustion, and emission characteristics of Mahua oil in a low heat rejection (LHR) diesel engine with retarded injection timing. oil, non-edible biodiesel, was evaluated against conventional both coated uncoated configurations. partially stabilized zirconia (PSZ) showed significant improvements. Brake thermal efficiency (BTE) increased by 9.15%, specific fuel consumption decreased 6.23% compared to standard engine. Emission analysis revealed reduction carbon monoxide (CO) unburnt hydrocarbons (UBHC) 20.35% 12.28%, respectively. However, nitrogen oxide (NOx) emissions 5.36% due higher combustion temperature induced PSZ coating. Exhaust gas (EGT) also rose 18.64%, highlighting enhanced combustion. concludes that when used an LHR timing coating, offers improved reduced emissions, making it viable alternative applications. Future work should explore effects varying compression ratios different biodiesel blends optimize performance further.
