When a lot of people picture a fire extinguisher, the picture that's called to mind belongs to a CO2 extinguisher. With their large, metals cylinders of bright red and hard horns, these fire extinguishers have been installed as an emergency measure in homes and businesses for generations. Carbon dioxide extinguishers could be differentiated from similar extinguishers through the lack of any kind of pressure gauge at the top of the tank. Diesel engines are becoming the predominant power behind modern tractors simply because they have the highest thermal efficiency of the internal or external combustion engine, due to their higher than normal compression ratio. Unlike gasoline engines, the diesel engines in tractors use highly compressed hot air to ignite the fuel as opposed to spark plugs.
