Abstract
The environmental preservation and energy conservation measures of marine engines are urgent concerns that need to be addressed. NABTESCO contributes to address these concerns by applying fluid control technology which it has developed in recent years to the electric control of marine diesel engines. ★ This technical paper describes the development of an intelligent hydraulic control valve intended for the fuel injection control of the unit pump system. The development concept was to create a high value product with the superior reliability of NABTESCO’s hydraulic control valves using simulation technology with particular emphasis at the early stages of development.
