HOPI CUMMINS diesel generator set adopt Cummins engines. The Cummins power generator with the world famous alternators---Stamford, Marathon, Leroy-Somer meet your requirements for reliability power quality, rated performance, and efficient operation. It features at low oil consumption, stable performance, easy maintenance, low operation cost, low emission, which are available in sizes ranging from 20kw to 800kw/25kva-1000kva. These clean, modern diesels with optional exhaust after treatment are suitable for either standby/emergency power, continuous or prime power applications.

Cummins Diesel Generator Set Main Features: 
1. High-strengh alloy cast iron cylinder body and its head. Quenching crank-shaft,  high strength and smooth operation.
2. Dc24v power start, generator for charging, electronic adjustment system, and its feature is better tan GB/T2820.5&ISO8525-5.
3. PT fuel system (Cummins patent) with unique protect design, low-pressure fuel supply and ultra-high injection pressure (100-140Mp), as well as good atomizing and complete combustion. STC, more complete combustion in higher & lower load. Lower fuel consumption, low pollution exhaust, in compliance to EU2/EU3/EPA/CARB reqirements.6CT PB/W, PN or AD injection pump is used.
4. Valves each cylinder, direct injection, inter cooling technology, utilize advanced exhaust-driven turbocharger, adaptable for high altitude, less than 1500m no loss of output power.
5. The heat-exchanger engine can works well in poor ventilation site, such as basement or antiaircraft tunnel.
