How Does the Cummins 6.0 Engine Work?

Understanding how the Cummins 6.0 engine works can help you appreciate its engineering brilliance. At its core, this engine operates on the principles of diesel combustion, which involves compressing air to a high pressure and injecting fuel into the combustion chamber. The high-pressure common rail (HPCR) system plays a crucial role in this process, delivering fuel at precise intervals to ensure optimal combustion.

The Cummins 6.0 also features a turbocharger, which enhances its performance by compressing air and forcing it into the engine's cylinders. This increases the amount of oxygen available for combustion, resulting in greater power output and efficiency. Additionally, the engine's intercooler reduces the temperature of the compressed air, further improving performance and fuel economy.

Here are some key components of the Cummins 6.0 and their functions:
