What is the maximum number of cylinders an engine can have?

An engine can have up to 16 cylinders, such as the Bugatti Veyron. Number of cylinders in car engines: Common cylinder counts for car engines include 3, 4, 5, 6, 8, 10, 12, and 16 cylinders. For regular family cars, 3, 4, and 6 cylinders are most common. Engines with 1 to 1.5 liters of displacement typically use 3 cylinders, 2.0 liters usually have 4 cylinders, 2.5 liters generally have 5 cylinders, around 3 liters usually have 6 cylinders, around 4 liters have 8 cylinders, 5.2 liters have 10 cylinders, and engines above 5.5 liters use 12 cylinders. Methods to identify the number of cylinders in a car: Check the spark plugs: for gasoline cars, the number of spark plugs equals the number of cylinders. For diesel cars, check the number of fuel injectors, as each injector corresponds to one cylinder. Examine the ignition leads: the number of ignition leads matches the number of engine cylinders. However, many modern cars no longer have separate ignition leads, as they are integrated with the ignition coils, with one coil per cylinder. Therefore, the number of ignition coils indicates the number of cylinders.
I've always been a car enthusiast and often test drive vehicles with various engines. Small cars commonly use 4-cylinder engines, which are economical and provide sufficient power for daily use. After driving a car with a V8 engine, the experience becomes more exhilarating, with rapid acceleration and strong push-back sensation. What excites me most are supercars like the Bugatti Veyron, which is equipped with a 16-cylinder engine - the highest cylinder count in mass-produced cars. The advantages of multi-cylinder engines are powerful performance, smooth operation, and minimal vibration. But why do manufacturers rarely produce engines with more than 16 cylinders? Primarily because of high costs, complex structures, troublesome maintenance, poor fuel efficiency, and non-compliance with environmental requirements. From a practical perspective, passenger vehicles seldom have engines exceeding this number unless they're custom modifications, but those are exceptions. I believe engine design needs to balance performance and practicality, with ultra-high cylinder counts reserved for only a handful of luxury items.
As someone who frequently deals with car repairs, I've encountered various engine issues. Common engines range from 4 to 12 cylinders, but in high-end supercars like Bugatti, we've seen 16-cylinder designs, which are practically the limit for automotive engines. Maintaining such multi-cylinder engines is a headache, requiring regular checks on cylinder balance, cooling systems, and fuel supply to prevent overheating or wear. Large truck or marine engines sometimes exceed 20 cylinders, such as the V20 engines used in some locomotives, but these are for industrial applications and not road vehicles. The advantage of multi-cylinder engines is their ability to provide massive torque and smooth operation, but the downsides include being heavy, fuel-thirsty, and space-consuming. During repairs, we always remind owners to focus on routine maintenance like oil and filter changes to extend engine life. Nowadays, many cars are shifting to fewer cylinders with turbocharging to balance efficiency and power.
