The first production Caterpillar diesel engine, the D9900, was manufactured in October 1931 after 18 months of design and testing. Over $1 million (U.S.) was spent on research and development — a considerable investment in those days. Originally designed to power the Caterpillar Sixty track-type tractor, this engine cemented the company as a pioneer in building vehicular diesel engines. In 1931, Caterpillar created a separate engine group and expanded its engine development to areas like CAT generator sets and CAT marine power.

Today, Cat engines are commonly found in electric power generation. Other uses for Cat power include engines for the petroleum industry, marine, locomotives, agricultural equipment, industrial power, construction equipment and many more. The diesel engine’s virtues of efficiency, dependability and simplicity were what prompted Caterpillar to pioneer its use in mobile equipment sixty years ago. These same attributes are characteristic of the Cat engines of today.
