There are currently 5 types of configurations of petrol/gasoline engines. In this video we will discuss in detail about the types of petrol engine based on configuration. 1. Straight/Inline engine
This is the most popular and widely used engine configuration today. Almost all the mainstream production cars that you are aware of use this engine configuration.
Configuration:
Cylinders are arranged next to each other - in a straight line.
Cylinders sit on top of the crankshaft.
Simple construction: a single cylinder head, cylinder bank and valve train.
Contains relatively lesser moving parts than the other engine configurations.
Typically a single exhaust manifold.

2. Flat/Boxer engine
We now move into the realm of performance engines! Although the number of manufacturers that use the boxer engine have dwindled, with Porsche and Subaru continuing to persist with the boxer engine in their current offerings, the automotive/racing world has fond memories of this engine layout.
This engine configuration was made famous by the original VW Beetle, which used an air-cooled, rear-mounted boxer engine.
Configuration:
The biggest design departure with an inline engine is that a boxer engine has horizontally opposed pistons.
These horizontally opposed pistons are contained in 2 cylinder banks, on either side of a common crankshaft.
Due to this layout, boxer engines are very low and also wide.
3. V-engine
We now enter a much vaunted performance temple that most have heard of. We've all had atleast one wall poster or a desktop wallpaper of a fire-breathing V12 car, that is the equivalent of automotive pornography!
These engines derive their name from the V-shape that their cylinder banks are in, on either side of the crankshaft.
Configuration:
*) Cylinders are located in a V-angle, on either side of a common crankshaft
*) The angle of the V varies between manufacturers, although ones where the V angle is 90 degrees is preferred in some racing applications.
*) Denoted by the numbers of cylinders, a V-configuration engine is a V6, V8, V10 or V12. The V2- used in motorcycles, is called a V-Twin.
*) Note that the V16 engine is no longer used in automotive applications, since its smaller siblings - the V10 and V12 provide similar output characteristics, at far lower costs
*) Higher the number of cylinders, closer does that car get to being a supercar- with the V12 engined cars occupying the highest pecking order in a car's society!
*) 2 exhaust manifolds
4. Rotary/Wankel engine
If ever there was a giant-killer in the engine world, its the Wankel engine. A very clever engine design that produced power comparable to engines much larger in size, with fewer moving parts, it finds mention here for what it represented, although its no longer in production today.
Mazda became synonymous with the Wankel engine, persisting and improving its design, till the last Wankel-engined Mazda in 2012, when the Wankel engine met its demise due to pollution norms.
Configuration:
No pistons! Used rotors instead.
Crankshaft remained stationary - the whole cylinder block moved around it instead
A 3-sided symmetrical central rotor placed around an eccentric shaft, in an oblong housing
A single rotation of the rotor covered all 4 strokes- intake, compression, ignition and exhaust.
5. W-engine
This is an extremely un-common engine configuration, with VW currently the only manufacturer of the W-type engine - the W16. This is a rather famous engine, used in the world-record shattering Bugatti Veyron hypercar, with 10 radiators, not less!
VW also recently announced a new W12 engine with its group company Bentley.
Configuration:
Cylinders are arranged in the shape of a W (or 2 tight Vs)
4 cylinder banks sharing a single crankshaft
2 cylinder heads, 2 camshafts
