In diesel engines, internal combustion results in expansion of high-temperature, high-pressure gases, which in turn move pistons, transforming chemical energy into mechanical energy. In 1919, Clessie Lyle Cummins founded Cummins Engine Company to improve diesel technology and produce the world's finest engines.
