To further strengthen our upgrade portfolio for Enterprise engines, Cooper acquired HOERBIGER’s Engines Services (HES) division in 2019. Cooper now offers even more upgrade technologies including the HyperFuel System™, HyperBalance™, HyperLogic™, ePCC™, and ePFI™. The Engine Services team offers engine emissions reduction and efficiency improvement upgrades that are applicable to all types of Enterprise engines.
Cooper’s facility in Houston, Texas serves as the Enterprise COE within Cooper’s global support network. Enterprise helped develop standards for nuclear standby diesels and engineered the technology to qualify components to these standards. The shop is a certified nuclear cylinder head repair facility and is the only certified shop to manufacture and repair Enterprise R-4 steel heads for the Nuclear industry.
The history of the Enterprise Engine dates all the way back to 1886 when the Enterprise Engine and Machining Company began building castings for gold mining machinery. After the notorious 1906 San Francisco earthquake and fire, the company played a significant role in the rebuilding of the city which expanded the business. For the next 35 years, the company built furnaces for the steel industry and started a new engine department to capitalize on the demand for diesel propulsion.
During World War II, the business built hundreds of diesel engines for the United States Navy for tug- boats, harbor craft, small vessels, and auxiliary electric generators on larger ships. Many Enterprise engines were sold to drive electric power generators in cities and towns across America. After the war, Enterprise expanded and began building the more modern diesels utilized in almost every conceivable type of prime-mover application from powering boats and pumping oil to generating electricity.
Cooper purchased the Enterprise business in 1988 and has continued to support Enterprise engines operating around the world in nuclear power plants, university and municipality cogeneration plants, US Navy and Air Force bases, and in gas transmission services.

Enterprise legacy engine product models
The Enterprise R Series line of engines was introduced in the 1950s with an in-line configuration followed a few years later by a vee-type. R Series engines are used primarily for marine and stationary power and nuclear standby service.
Enterprise spark-ignited HA, HV, and HVA engines feature high performance, fuel conservation, greater operating flexibility, and cost efficiency. Hundreds of H Series engines were put into service powering generators and driving compressors. They have the capability to run low BTU gas or gas with heavy hydrocarbon components.
