Both compress air entering an internal-combustion engine, with the goal of increasing the amount of oxygen available in the fuel-air mixture that enters the cylinders, and thus increasing the amount of energy available to each power-stroke of each piston. A supercharger is direct-driven from the engine itself, typically by a toothed belt from the driveshaft, but occasionally directly from the driveshaft itself. The most common form is an external-compression, or Roots supercharger , which uses counterrotating lobed “rotors” or gears to trap air (or fluid, in other uses) against the inside of an enclosure, and move it from one side to the other. Explaining this is the exact reason animated gifs were invented: Those gifs are two-dimensional (well, three, with the third being time rather than Z, but..) the most common implementation uses three-lobe rotors which have a helical twist, in order to minimize pulsation or “hammering” of the output. It’s worthy of note tha
What is Engine? What are Main Types of Engine? Today we will discuss about engine and types of engine used in automobile. Any device which can convert heat energy of fuel into mechanical energy is known as engine or heat engine. Engine is widely used in automobile industries or we can say that engine is the heart of an automobile. Basically engine may be classified into two types. Types of Engine: 1. External combustion (E.C.) Engine It is an engine in which combustion of fuel take place outside of the engine. In this type of engine heat, which is generated by burning of fuel is use to convert the water or other low boiling temperature fluid into steam. This high pressure steam used to rotate a turbine. In this engine we can use all solid, liquid and gases fuel. These engines are generally used in driving locomotive, ships, generation of electric power etc. Advantages of E.C. engine- In these engines starting torque is generally high. Becaus
