How Rotary Engines Work

No more boring introductions, lets get started & understand how does a Wankel engine work & what exactly it is !
History :-
The first Wankel engine was developed by German engineer – Felix Wankel. Wankel received his first patent for the engine in 1929.
However, the Wankel engine design used today  is designed by Hanns Dieter Paschke – which he adopted forming the modern engine !

Wankel engine :-
Wankel engine is an Internal combustion engine unlike the piston cylinder arrangement. This engine uses the eccentric rotor design which directly converts the pressure energy of gases into rotatory motion. While in the piston-cylinder arrangement, the linear motion of the piston is used to convert into rotatory motion of crankshaft.
Basically, in a simple way, the rotor revolve in housings shaped in a fat figure-of-eight.

Rotor :- The rotor has three convex faces which acts like a piston. The 3 corners of rotor forms a seal to the outside of the combustion chamber. It also has internal gear teeth in the centre on one side. This allows the rotor to revolve around a fix shaft.
Housing :- The housing is epitrochoidal in shape(roughly oval). The housing is cleverly designed as the 3 tips or corners of the rotor always stay in contact with the housing. The intake and exhaust ports are located in the housing.
Inlet & exhaust ports :- The intake port lets fresh mixture enter into combustion chamber & the exhaust gases expel out through outlet/exhaust port.
Spark plug :- A spark plug delivers electric current to the combustion chamber which ignites the air-fuel mixture leading to abrupt expansion of gas.
Output shaft :- The output shaft has eccentric lobes mounted on it, which means they are offset from
centreline of the shaft. The rotor is not in pure rotation, but we need these eccentric lobes for pure rotation of the shaft.

Note :- The output shaft is a thing which can’t be explained completely in words. It is quite difficult to imagine it’s contribution in the working. this video link might help you to understand it.

Transverse Vs Longitudinal Engines: The Pros And Cons

The way in which an engine is orientated can have a huge influence on the rest of a car’s design. Should the car be rear-wheel drive? What size of engine is expected? Are there space issues that could influence which way the engine lies? All these questions have to be answered by the engineers responsible for the car, as the powertrain setup can have a large impact on how the car goes, handles and stops. Looking at front-engined cars, the two possible orientations are longitudinal and transverse, with each having its own benefits and drawbacks that can govern which is chosen for the car at hand. In-light of this engineering decision, here’s a basic guide to the features of each engine layout and which is best for different applications. Transverse engines Transverse engines are mounted perpendicularly to the direction of travel, lying horizontally within the engine bay. This is predominantly used in front-engined, front-wheel drive setups but has also been implemented i

How Twin-clutch Transmission Works (DSG)

The dual-clutch transmission, also known as the Direct Shift Gearbox (DSG) or twin-clutch transmission, is an automated transmission that can change gears faster than any other geared transmission. Dual clutch transmissions deliver more power and better control than conventional automatic transmission and faster performance than manual transmission. Originally marketed by Volkswagen as the DSG and Audi as the S-Tronic, dual-clutch transmissions are now offered by several automakers, including Ford, Mitsubishi, Smart, Hyundai and Porsche. DRIVING A CAR WITH A TWIN-CLUTCH / DSG TRANSMISSION. Twin-clutch equipped cars do not have a clutch pedal; the clutch is engaged and disengaged automatically. The twin-clutch transmissions bridge uses an automatic-style shift selector with a traditional P-R-N-D or P-R-N-D-S (Sport) shift pattern. In "Drive" or "Sport" mode, the dual-clutch transmission operates as a regular automatic. In "Drive" mode, the transmission
