A Diesel Bhatti Machine is a cooking device commonly used in outdoor settings where electricity or gas is not available. It is popular in rural areas of South Asia, particularly in India. The machine is a rectangular metal box with a perforated tray on top for the cooking vessel and a fuel tank at the bottom. The fuel, diesel, is ignited using a spark plug, and the heat generated is used for cooking. The temperature can be adjusted by the air vents located on the sides of the machine. Diesel Bhatti Machines come in various sizes.
