Porduct application
The engine power range produced by Chongqing Cummins is 200HP-1600HP. The products are mainly used in heavy-duty vehicles, large passenger cars, construction machinery, mining machinery, petroleum machinery, rail machinery, port machinery, stationary and mobile diesel generator sets, power stations, and ship propulsion. Power units and auxiliary power units, pump power units and other power units. NTA855 has many uses. It can be equipped with generator sets. For example, it can be equipped with generator sets for ships. It can also be equipped with vehicles. If equipped with vehicles, it is mainly construction machinery, bulldozers, excavators, cranes, etc.Now we take NTA855-G1 as an example, analyze the specific parameters of this engine
