Though biofuels never gained the growth and popularity of diesel fuel, a late 20th-century resurgence in research has revived interest in biofuels and biodiesel engines. Students will consider this phenomenon, the diesel engine, and how it relates to their calorimeter apparatus as a thermal system while also seeking to answer the driving question, “How do biodiesels compare with their virgin source oils, traditional petro-diesel fuel, and kerosene with regard to their potential use as fuels?” Note: The biodiesel sample preparation process that is required before students begin the activity takes a minimum of 6 calendar days from start to finish.
