Enterprise Piston Web


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.
