1.	What is a dual fuel engine?(a) The engine which uses gaseous and liquid fuel(b) The engine which uses two liquid fuels(c) The engine which uses two gaseous fuels(d) The engine which uses one liquid and any other fuelThis question was posed to me in an online interview.Question is taken from Nonconventional Engines in division Nonconventional Engines, Conventional Energy Sources & Cooling System of Automobile Engineering
Answer» Right option is (a) The engine which uses GASEOUS and liquid fuel For explanation: The duel fuel engine uses gaseous and liquid fuel. The dual-fuel engine works on the diesel CYCLE. The gaseous fuel is called the PRIMARY fuel. The mixture of air and gaseous fuel is compressed in the CYLINDER.
