BP Auto Spares India Talks about the Working of Rotary Engines

HARARE, Zimbabwe - May 1, 2018 - PRLog -- Let's take a time travel and go back to the time when the rotary engines came into being. The rotary engine came around in the year 1929 and was patented by a German engineer Felix Wankel. A rotary engine is an internal combustion engine; similar to the engine in your car, but the semantic of its working is completely different from the traditional piston engine. In a piston engine, the same cylinder carries out four quintessential jobs of intake, compression, combustion, and exhaust. Contrary to this, in a rotary engine, all these functions are carried out in their own part of the housing, which means each task is carried out by a separate cylinder.

The car experts of one of highly acclaimed and proclaimed Suzuki Car Spare Parts dealers, BP Auto Spares India in this press release will tell you about the fascinating working of a rotary engine. He starts by saying," A rotary engine, since it was developed by the famous German engineer Felix Wankel, is sometimes referred to as a Wankel engine, or Wankel rotary engine. They are exponentially and radically different in make and structure than the standard reciprocating piston engines. These engines were later fully developed and tested by a German firm in the year 1956. A basic rotary engine works on a similar principle as most the other internal combustion engines do. A mixture of fuel and air is drawn into the cylinder and then burned and compressed. But after this, the entire scenario changes in rotary engines.  Instead of pistons moving up and down in cylinders, rotary engines have a different way of doing things. Rotary engines boast a single rotor inside a sealed housing. The rotor resembles the shape of a triangle, the ends of which are slightly convex. The sealed housing inside which the rotor lies is oval-shaped and the long edges have small indentations in the middle, giving it an epitrochoid shape. Now, the main thing to note here is the movement of the rotor inside the housing. It does not rotate on a single spot; instead, the rotor follows an eccentric path around the housing inside the chamber, creating three separate sealed-off areas as it moves."

He further explains, in a traditional piston engine, the pressure created when the air and fuel mixture is burned is contained in the cylinders which force the pistons to move up and down. This reciprocating motion created by the upward and downward movement of the pistons is converted into rotational motion by the connecting rods and crankshaft to power the vehicle. Whereas in a rotary engine the pressure of air and fuel combustion is locked inside the sealed chamber. The eccentric path the rotor follows around the housing, keeps the ends of the rotor in contact with the housing, creating three separate volume of gas. This volume of gas expands and contracts with the movement of the rotor inside the chamber. This expansion and contraction are responsible for drawing air and fuel mixture into the engine, where it is burned and compresses to power the engine."
