What are the arrangements of cylinders?

Cylinder arrangements: In-line L-type, V-type, W-type, horizontally opposed engine, and R-type rotary engine. In an in-line L-type engine, all cylinders are arranged at the same angle in a single plane, using only one cylinder head, and the structure of the cylinder block and crankshaft is relatively simple. The V-type engine divides all cylinders into two groups, arranging adjacent cylinders at a certain angle so that the two groups form a V-shape when viewed from the side. The W-type engine's cylinder arrangement is approximately W-shaped, a variant of the V-type engine. The horizontally opposed H-type engine has a cylinder angle of 180 degrees. The R-type rotary engine, also known as the Miller cycle engine, directly converts the combustion expansion force of the fuel into driving torque.
I've driven quite a few cars with various cylinder arrangements. The inline type is the most common, like four or six cylinders arranged in a straight line, used in older sedans. It saves space and costs less, but vibration can be significant. V-type engines, such as V6 or V8, have cylinders split into two rows at an angle, installed in sports cars or SUVs. They offer strong acceleration and low noise but have complex structures and expensive maintenance. The horizontally opposed type lays cylinders flat on both sides, favored by brands like Subaru. It provides a low center of gravity for stable cornering but is troublesome to repair. There's also the W-type with cylinders in three rows, used in high-end Volkswagen models, offering dense power but large size. These designs all balance space, cost, and performance. When choosing a car, it depends on your needs. I think inline engines suit family use, while V-types are for those pursuing a sense of speed.
As a car enthusiast who loves speed, I believe the cylinder arrangement directly impacts the driving experience. The inline-four is super popular in everyday sedans—fuel-efficient but a bit sluggish at takeoff. V6 engines, like those in American muscle cars, feature cylinders arranged in a V-angle, delivering an exhilarating roar at high speeds with stable power output and good balance, though maintenance can be tricky due to more parts. The horizontally opposed layout lowers the car's center of gravity, enhancing grip in corners—just drive a Subaru to feel its charm. The W-type is rare, stacking cylinders in three rows for explosive power but heavy fuel consumption. Each engine layout complements the overall vehicle design, and after driving enough, you'll find the V-type suits spirited driving best.
