Category: In-line Engine
In aviation, an in-line engine refers to an internal combustion engine with banks rather than rows of cylinders, including straight and V engines, but excluding radial and rotary engines
Usually found in 4- and 6-cylinder configurations, the straight engine has all cylinders aligned in one line, with no or only minimal offset. A straight engine is considerably easier to build than an otherwise equivalent V engine because the cylinder bank can be milled from a single metal casting and it requires fewer cylinder heads and camshafts. In-line engines are also much smaller in volume than designs like the radial, and can be mounted in any direction. Straight configurations are simpler than their V-shaped counterparts.
In a V engine, the cylinders and pistons are aligned, in two separate planes, so that they appear to be in a “V” when viewed along the axis of the crankshaft. The V configuration reduces the overall engine length, height and weight compared to an equivalent straight engine. It is common for V engines to be described with V# notation, where # is how many cylinders it has:

Supermarine Spitfire
Thursday, December 4th, 2008
Probably the most famous British aircraft of all time, the great fighter played a secondary role in the Battle of Britain to the less glamourous Hawker Hurricane. But the Spitfire’s elegant looks, excellent handling characteristics, and huge production give it a unique place in aviation history. There was a bit of happenstance in the Spitfire’s [...]
