Types of Three-Cylinder Engines Available:
First Inline3, V3, and W3.

The Inline-three engine (also called an inline-triple or Straight-three engine) is a three-cylinder piston engine with cylinders arranged in a line along a common crankshaft. Straight-three engines have been used in various motorcycles, cars, and agricultural machinery.

The V3 engine is a V engine with two cylinders in one bank and one cylinder in the other bank. It is a rare configuration mostly used in two-stroke engines for motorcycles competing in Grand Prix motorcycle racing.

A W engine is a type of piston engine where three banks use the same crankshaft, resembling the letter W when viewed from the front. Due to their shape, these are also known as "broad arrow" engines.

Advantages of 3 - cylinder engines
Compact size: Having one cylinder less to accommodate gives manufacturers more space in the engine bay.

Better fuel efficiency: The fewer the cylinders, the lesser the area for metal-to-metal contact, and the lesser such contact, the better the fuel efficiency of the car.

Less raw material usage: The fewer the number of cylinders, the lesser the total material required to manufacture the engine. This gives a significant advantage to the manufacturer in terms of cost savings that they can transfer towards lowering the price of the car.

Lighter weight: This is a pretty straightforward advantage.

3 Cylinder Engines | Disadvantages
Less Responsive Engine: The lower amount of cylinders makes the engine respond in a bit delayed manner. Although the difference seems negligible, the difference can be felt by someone who has driven or is used to driving a 4-cylinder.

Not Refined: A 3-cylinder engine requires more work than a 4-cylinder engine due to the lower number of cylinders. The 3 cylinders perform most of the work against the 4 cylinders, making them a tad bit noisier than their 4 cylinder counterparts.
