TLDR
In this article, the effect of a fraction of biodiesel in the blends, the variation of load (20 to 100% in a step of 20%) and compression ratio (CR) (14:1, 16:1 and 18:1) on combustion characteristics of non-edible linseed (Linum usitatissimum) biodiesel blended with petrodiesel (PD) are presented.Abstract:
In this article, the overall combustion characteristics of non-edible linseed (Linum usitatissimum) biodiesel blended with petrodiesel (PD) are presented. The objective of the present study is to investigate the effect of a fraction of biodiesel in the blends, the variation of load (20 to 100% in a step of 20%) and compression ratio (CR) (14:1, 16:1, and 18:1) on combustion characteristics. The obtained result, compared with baseline fuel PD, is operated at rated CR 17.5:1. The result shows the higher value of cylinder combustion pressure (CP), a rate of pressure rise (RPR), cumulative heat release, combustion duration, and combustion mean gas temperature and lower ignition delay (ID) for biodiesel and its blends compared with PD. On an average, the ID increased by 30% and 3.3% at CR 14:1 and 16:1, respectively, and reduced by 28.3% at CR 18:1 for LB blends.read more

Experimental investigation of ethanol/diesel and ethanol/biodiesel on dual fuel mode HCCI engine for different engine load conditions
TL;DR: In this article, the effect of different mass flow rates of ethanol on dual fuel mode HCCI engine working under different load conditions was investigated and the results showed that with an increase in the mass flow rate of ethanol, ignition delay (ID) increases, combustion duration (CD), in-cylinder pressure and temperature are reduced; which leads to reduce NOX emission and smoke opacity of ethanol/diesel (E+D) and ethanol/biodiesel (E−B20) dual-fuel mode HCI engine compared to neat diesel engine.

Triglycerides-based diesel fuels

TL;DR: The main advantages of using biodiesel are its renewability, better-quality exhaust gas emissions, its biodegradability and given that all the organic carbon present is photosynthetic in origin, it does not contribute to a rise in the level of carbon dioxide in the atmosphere and consequently to the greenhouse effect as mentioned in this paper.
