IN A 1.6L V6 ENGINE, WHAT DOES THE 1.6L REFER TO?

In a 1.6L V6 engine, what does the 1.6L refer to?

Engines are measured in litres. The parts of the engine where the fuel is burned to produce movement are called the cylinders – a car will usually have three, four, six or eight cylinders – and the volme of these cylinders is measured in litres. Simply,it is is the total displacement of all cylinders when piston moves either from TDC(Top dead center) to BDC(Bottom dead center) or BDC to TDC .Its also termed as stroke volume.

A 1.6 litre engine will have 1.6 litres of cylinder space altogether. 

1.6L = 1.6 Liters (or 1600 cubic centimeters or 1.6 decimeters)

V6 = 6 cylinders in a V shape.This type of engine is used in F1 racing - max rpm at 15,000. They use this engine because the pistons are light, small, the stroke is reduced, and this allows the engine to reach that insane rpm. 

So if it has six cylinders, each cylinder has a volume 1600/6 = 267 cc

A 1.6L engine might also be referred to as 1.6 in brochures. Sometimes, the size of the engine will be part of the name of the car.
