In order to understand the step-by-step process, let’s take a look at the diesel engine components and functions.

The diesel engine working principle was completed by the inventor, Rudolf Diesel, in 1892, and the first prototype was created in 1897. In the years following, he continued to work on improving his theory, and others soon realized the potential of this invention and started making their own versions. One of the people to recognize the importance of the diesel engine was Clessie Lyle Cummins. In 1919, He founded Cummins Engine Company with a goal of improving diesel technology and producing the world’s finest engines. Thanks to his vision, Cummins Inc. is now a global leader, producing advanced diesel engines for applications ranging from heavy-duty trucks and consumer pickups to industrial mining and oil drilling.
