What engine is the 5 cylinder inline:  it s a five-cylinder piston engine where cylinders are arranged in a line along a common crankshaft.

What is the 5 cylinder inline displacement: it is in a range between 1984 cc and 3654 cc in recent model line up powertrain.

How much is the power of the 5 cylinders inline: the power of the 5 cylinders is in a range from 90bhp to 400 bhp

Which cars use 5 cylinder inline engine: 5 inline has been used by many brands such Alfa Romeo, Mercedes, Vw group and Volvo among the other but only for limited number of models in high end vehicles.

A five-cylinder engine inline is almost as compact as an inline-four, and almost as smooth as a straight-six engine so can be easily  positioned in the chassis front transverse or front longitudinal for front wheels drive, rear wheels drive and all wheel drive traction. The engine sound is really nice and smoothness more similar to a six in line than a 4 inline engine expecially at low and mid rpm.

The five-cylinder engine's advantage over a comparable four-cylinder engine is related to the rotation process. In a four-stroke cycle the engine fires every cylinder once every 720 degrees so each piston fires for every two rotations of the crankshaft, 720 degrees ÷ 4 = 180 degrees which is two power strokes per revolution of the crankshaft. A given power stroke can last no more than 180 degrees of crankshaft rotation, so the power strokes of a four-cylinder engine are sequential, with no overlap. At the end of one cylinder's power stroke another cylinder fires where in the 5 cylinder in line the power stroke last  720 degrees ÷ 5 = 144 degrees with always 2 pistons pushing a little simultaneously.

However as the camshaft timing each power stroke lasts approximately 120 degrees [ending when the exhaust valve opens], this means that there is a very short period of about 24 degrees when the crankshaft receives no torque. 

The use of straight-five petrol engines in mass production cars only became popular with reliable fuel injection. A five-cylinder engine using a carburetor fuel system has an unavoidable problem in that the length of the inlet manifold between the carburetor varies too greatly between cylinders at the ends of the engine and those nearer the carburetor for reliable and consistent fuel delivery. Using multiple carburetors, (two or three) always results in one carburetor feeding more cylinders than the other, which also produces running and tuning problems. Multi-point fuel injection solves all the above problems by fueling each cylinder individually. This fueling issue was never present in diesel engines (except the Volvo D5) which, like all diesel engines, used fuel injection from the very start, which is why large five-cylinder diesels were commonly seen decades before the type's adoption for automotive use.

As the engine fires once every 144 degrees crankshaft angle (720 degrees / 5 = 144 degrees). Most common firing order for inline-fives is 1-2-4-5-3 used by Volvo, VW group, GM and Honda.
