dc.description.abstractThere is a need to find alternative fuels to replace the fossil fuels and also to reduce the harmful emissions. Biomass based fuels are one such alternate fuel to diesel. The main aim of this study is to find the suitability of sweet almond oil (Prunus amygdalus dulcis oil) in compression ignition engine (CI), moreover to enchance the performance and emission parameters by premixed charge compression ignition (PCCI) combustion with hydrogen fuel. A decrease in diesel engine performance was observed with the blend. Further to reduce the fossil fuel consumption, hydrogen was introduced in the intake manifold. As hydrogen is inducted well before the combustion, it makes premixed charge with intake air for better combustion. The results reveal that 30LPM (litres per minute) hydrogen flow rate lead to maximum improvement in engine performance. Compared to the blend, the thermal efficiency increased by 8.38 % at full load, and a reduction of 70 %, 56 % and 27 %, for HC, CO and smoke emissions respectively was observed. However, an increase of 14 % in NO emission was observed. Hydrogen addition along with SAO20 (20 % blending of sweet almond oil biodiesel in diesel) operation increases the in-cylinder peak pressure from 79.8 bar to a maximum of 89.5 bar at full load. Hydrogen increases the rate of heat released in the premixed combustion but the peak heat release rate is delayed with different hydrogen flow rates due to lower centane number of the combustible mixture. The novelty of this paper is to run the engine with unexplored low carbon biofuel prunus amygdalus dulcis oil in diesel engine and also to improve the performance by premixed hydrogen fuel.en_US
