“…They also investigated its ignition and combustion behaviour after injection in a constant volume combustion chamber. Ashraful et al (2014) had compared fuel properties, engine performance, and emission characteristics of biodiesel from various non-edible vegetable oils (karanja, polanga, mahua, rubber seed, cotton seed, jojoba, tobacco neem, linseed and jatropha).Various biodiesel types with different vegetable oils (soybean, rapeseed, mustard, canola, palm, sunflower, rice bran, jatropha, karanja and used cooking oil) were analysed by Issariyakul and Dalai (2014). Biodiesel fuels prepared from different vegetable oil sources (canola, soybean, sunflower, and corn) were studied through electrochemical impedance spectroscopy by M' Peko et al (2013).…”
