4 cylinder in line diesel engines are new models that our company has developed for markets needs. Adopting latest design idea and advanced technology, this series engines have good economic performance targets, compact structupower, easy operation and maintenance and perfect reliability, which keep series and common-use components of series 190 diesel engine and remain a leading level in its class. 
The engines are mainly used in fishing and ship transport as well as land power generation and engineering machinery, etc.
