What is V6 Engine? | Difference between V6 Engine and V8 Engine

The V engines are the most commonly used engines. The ‘V’ denotes the arrangement of the cylinders in the engine. The V engines have different types, and the V6 engine is one of them. The V6 engine is a type of engine in which six cylinders are arranged in a V configuration. This article mainly explains the V6 engine working, design, and applications.

What is a V6 Engine?

A V6 engine is a type of V engine that contains six cylinders arranged in two equal rows. These cylinders are arranged in the V configuration. All these cylinders share a common crankshaft.

The Delahaye, Deutz Gasmotoren Fabrik, and Marmon Motor Car Company were designed and produced the first V6 engines. The Lancia V6 engine was built after World War II, in 1950 for the Lancia Aurelia, and the Buick V6 engine in 1962 for the Buick Special.

Design of V6 Engine

Due to the short length of the V6 engine, it is often used as a large engine option for vehicles with inline 4-cylinder engines, especially transverse engine vehicles.

One of the disadvantages of luxury cars is that the V6 generates more vibration than an I6 engine. Some sports cars have a low center of gravity (for better handling) and therefore contain a flat-six engine instead of the V6.

The latest V6 engines typically range from 2.5 to 4.0 L (153 to 244 cu in) but are larger. However, the displacement of modern V6 engines is typically between 2.5 to 4.0 L (153 to 244 cu in), though larger and smaller examples have been produced, such as the 1.8 L (110 cu in) Mazda V6 used in the 1991–1998 Mazda MX-3, or the 1.6 L (98 cu in) Mitsubishi V6 engine used in the 1992–1998 Mirage/Lancer. The largest V6 engine was the 7.8 L (476 cu in) GMC V6 used in the 1962 GMC C/K series 6500.

V6 Engine Working

The V6 engine contains six cylinders that are arranged in a V-shaped configuration. Each cylinder undergoes four different strokes: intake stroke, compression stroke, combustion stroke, and exhaust stroke.

During the intake stroke, a fuel-air mixture is introduced into the engine cylinder. When the mixture enters the engine cylinder, the compression stroke takes place where the mixture is compressed.

When the air-fuel mixture is compressed according to the requirements, then the combustion stroke starts. During the ignition stroke, the air-fuel mixture is ignited, and the combustion process starts. When the mixture is combusted, the power is generated, which is used to run the vehicle.

At the last, the exhaust gases are expelled into the atmosphere during the exhaust stroke. The V6 engine design is ideal for larger and mid-sized vehicles.

Pros and Cons of the V6 Engine

Pros of the V6 Engine

  • Power and Performance: A V6 engine generally offers an excellent equilibrium of performance and power. These engines generate more power than smaller engines. However, they are more fuel efficient than large engines such as V8 engines.
  • Battery Fuel Economy: These engines have higher fuel efficiency than V8 engines and other large engines.
  • Weight: They have lower weight compared to larger engines such as V8 and V12 engine.
  • Low Maintenance Cost: V6 engines contain fewer parts compared to other larger engines. Therefore, they have lower maintenance costs than larger engines.
  • Small Size: They have a smaller footprint than larger counterparts, such as V8 engines.

Cons of V6 Engine

  • Cost: V6 engines have higher costs than smaller engines, such as V4 engines.
  • Design: They have a complex design compared to smaller engines.
  • Power: V6 engines have lower output power than larger engines, such as V8 engines.
  • High-end Power: These engines have limited high-end power compared to larger engines.
  • Fuel Efficiency: These engines have lower fuel efficiency compared to smaller engines.
